Insects of the family Formicidae, very common and widespread, probably the most successful of all the insect groups. All ants are social insects, and most colonies contain three castes, queens, males, and workers. Their habits are often very elaborate and a great many studies have been made of ant behavior. Ants produce a number of secretions that function in offense, defense, and communication. (From Borror, et al., An Introduction to the Study of Insects, 4th ed, p676)

Assessing genetic structure with multiple classes of molecular markers: a case study involving the introduced fire ant Solenopsis invicta. (1/1059)

We used 30 genetic markers of 6 different classes to describe hierarchical genetic structure in introduced populations of the fire ant Solenopsis invicta. These included four classes of presumably neutral nuclear loci (allozymes, codominant random amplified polymorphic DNAs (RAPDs), microsatellites, and dominant RAPDs), a class comprising two linked protein-coding nuclear loci under selection, and a marker of the mitochondrial DNA (mtDNA). Patterns of structure revealed by F statistics and exact tests of differentiation were highly concordant among the four classes of neutral nuclear markers, although the microsatellites were the most effective markers for detecting structure. The results from the mtDNA complemented those from the neutral nuclear markers by revealing that strong limitations to female-mediated gene flow were the cause of the local structure registered by the nuclear markers. The pattern of structure inferred from the selected nuclear loci was markedly different from the patterns derived from the other sets of markers but was predictable on the basis of the presumed mode of selection acting on these loci. In general, the results for all six classes of markers can be explained by known features of the social and reproductive biology of fire ants. Thus, the results from these diverse sets of markers, combined with detailed natural history data, provide an unusually complete picture of how the fundamental evolutionary forces of gene flow, drift, and selection govern the distribution of genetic variation within and between fire ant populations.  (+info)

Calibration of vector navigation in desert ants. (2/1059)

Desert ants (Cataglyphis sp.) monitor their position relative to the nest using a form of dead reckoning [1] [2] [3] known as path integration (PI) [4]. They do this with a sun compass and an odometer to update an accumulator that records their current position [1]. Ants can use PI to return to the nest [2] [3]. Here, we report that desert ants, like honeybees [5] and hamsters [6], can also use PI to approach a previously visited food source. To navigate to a goal using only PI information, a forager must recall a previous state of the accumulator specifying the goal, and compare it with the accumulator's current state [4]. The comparison - essentially vector subtraction - gives the direction to the goal. This whole process, which we call vector navigation, was found to be calibrated at recognised sites, such as the nest and a familiar feeder, throughout the life of a forager. If a forager was trained around a one-way circuit in which the result of PI on the return route did not match the result on the outward route, calibration caused the ant's trajectories to be misdirected. We propose a model of vector navigation to suggest how calibration could produce such trajectories.  (+info)

Attachment forces of ants measured with a centrifuge: better 'wax-runners' have a poorer attachment to a smooth surface. (3/1059)

The symbiotic ant partners of glaucous Macaranga ant-plants show an exceptional capacity to run on the slippery epicuticular wax crystals covering the plant stem without any difficulty. We test the hypothesis that these specialised 'wax-runners' have a general, superior attachment capacity. We compared attachment on a smooth surface for 11 ant species with different wax-running capacities. The maximum force that could be withstood before an ant became detached was quantified using a centrifuge recorded by a high-speed video camera. This technique has the advantage of causing minimum disruption and allows measurements in very small animals. When strong centrifugal forces were applied, the ants showed a conspicuous 'freezing reflex' advantageous to attachment. Attachment forces differed strongly among the ant species investigated. This variation could not be explained by different surface area/weight ratios of smaller and larger ants. Within species, however, detachment force per body weight (F/W) scaled with the predicted value of W(-)(0.33), where W is body weight in newtons. Surprisingly, our results not only disprove the hypothesis that 'wax-runners' generally attach better but also provide evidence for the reverse effect. Superior 'wax-runners' (genera Technomyrmex and Crematogaster) did not cling better to smooth Perspex, but performed significantly worse than closely related congeners that are unable to climb up waxy stems. This suggests an inverse relationship between adaptations to run on wax and to attach to a smooth surface.  (+info)

Octopamine reverses the isolation-induced increase in trophallaxis in the carpenter ant Camponotus fellah. (4/1059)

Social deprivation is an unusual situation for ants that normally maintain continuous contact with their nestmates. When a worker was experimentally isolated for 5 days and then reunited with a nestmate, she engaged in prolonged trophallaxis. It is suggested that trophallaxis allows her to restore a social bond with her nestmates and to re-integrate into the colony, particularly via the exchange of colony-specific hydrocarbons. Octopamine reduced trophallaxis in these workers as well as hydrocarbon transfer between nestmates, but not hydrocarbon biosynthesis. Administration of serotonin to such 5-day-isolated ants had no effect on the percentage of trophallaxis. Administration of phentolamine alone, an octopamine antagonist, had no effect, but when co-administrated with octopamine it reduced the effect of octopamine alone and restored trophallaxis to control levels. Moreover, the observed effect of octopamine was not due to a non-specific effect on locomotor activity. Therefore, we hypothesise that octopamine mediates behaviour patterns linked to social bonding, such as trophallaxis. On the basis of an analogy with the role of norepinephrine in vertebrates, we suggest that the levels of octopamine in the brain of socially deprived ants may decrease, together with a concomitant increase in their urge to perform trophallaxis and to experience social contacts. Octopamine administration may reduce this social deprivation effect, and octopamine could therefore be regarded as being partly responsible for the social cohesion between nestmates in ant colonies.  (+info)

Electron paramagnetic resonance study of the migratory ant Pachycondyla marginata abdomens. (5/1059)

Electron paramagnetic resonance was used to investigate the magnetic material present in abdomens of Pachycondyla marginata ants. A g congruent with 4.3 resonance of high-spin ferric ions and a very narrow g congruent with 2 line are observed. Two principal resonance broad lines, one with g > 4.5 (LF) and the other in the region of g congruent with 2 (HF), were associated with the biomineralization process. The resonance field shift between these two lines, HF and LF, associated with magnetic nanoparticles indicates the presence of cluster structures containing on average three single units of magnetite-based nanoparticles. Analysis of the temperature dependence of the HF resonance linewidths supports the model picture of isolated magnetite nanostructures of approximately 13 nm in diameter with a magnetic energy of 544 K. These particles are shown to present a superparamagnetic behavior at room temperature. The use of these superparamagnetic particle properties for the magnetoreception process of the ants is suggested.  (+info)

Pinpointing food sources: olfactory and anemotactic orientation in desert ants, Cataglyphis fortis. (6/1059)

Desert ants, Cataglyphis fortis, search for a repeatedly visited food source by employing a combined olfactory and anemotactic orientation strategy (in addition to their visually based path-integration scheme). This behaviour was investigated by video-tracking consecutive foraging trips of individually marked ants under a variety of experimental conditions, including manipulations of the olfactory and wind-detecting systems of the ants. If the wind blows from a constant direction, ants familiar with the feeding site follow outbound paths that lead them into an area 0.5-2.5 m downwind of the feeding station. Here, the ants apparently pick up odour plumes emanating from the food source and follow these by steering an upwind course until they reach the feeder. If the food is removed, foragers usually concentrate their search movements within the area downwind of the feeding site. Only when the wind happens to subside or when tail-wind conditions prevail do the ants steer direct courses towards the food. Elimination of olfactory input by clipping the antennal flagella, or of wind perception by immobilising the bases of the antennae, altered the foraging behaviour of the ants in ways that supported these interpretations. Ants with clipped flagella were never observed to collect food items.  (+info)

Lateral optic flow does not influence distance estimation in the desert ant Cataglyphis fortis. (7/1059)

The present account answers the question of whether desert ants (Cataglyphis fortis) gauge the distance they have travelled by using self-induced lateral optic-flow parameters, as has been described for bees. The ants were trained to run to a distant food source within a channel whose walls were covered with black-and-white gratings. From the food source, they were transferred to test channels of double or half the training width, and the distance they travelled before searching for home and their walking speeds were recorded. Since the animals experience different motion parallax cues when walking in the broader or narrower channels, the optic-flow hypothesis predicted that the ants would walk faster and further in the broader channels, but more slowly and less far in the narrower channels. In contrast to this expectation, neither the walking speeds nor the searching distances depended on the width or height of the channels or on the pattern wavelengths. Even when ventral-field visual cues were excluded by covering the eyes with light-tight paint, the ants were not influenced by lateral optic flow-field cues. Hence, walking desert ants do not depend on self-induced visual flow-field cues in gauging the distance they have travelled, as do flying honeybees, but can measure locomotor distance exclusively by idiothetic means.  (+info)

Three energy variables predict ant abundance at a geographical scale. (8/1059)

Energy theory posits three processes that link local abundance of ectotherms to geographical gradients in temperature. A survey of 49 New World habitats found a two order of magnitude span in the abundance (nests m(-2)) of ground nesting ants (Formicidae). Abundance increased with net primary productivity (r2=0.55), a measure of the baseline supply of harvestable energy. Abundance further increased with mean temperature (r2=0.056), a constraint on foraging activity for this thermophilic taxon. Finally for a given mean temperature, ants were more abundant in seasonal sites with longer, colder winters (r2 = 0.082) that help ectotherm taxa sequester harvested energy in non-productive months. All three variables are currently changing on a global scale. All should be useful in predicting biotic responses to climate change.  (+info)

Leafcutter ants are different than most other ants when it comes to their source of food. Most ants feed on sugary substances to obtain carbohydrates, and greasy substances or meats to obtain protein. Not so with the leafcutter ants. Leafcutters primary source of food is fungus. This process begins with leafcutter ant workers bringing pieces of leaves and other plant materials back to their nest. The collector ants do not eat this plant material since they are not able to digest all of the nutritional compounds in the plants they gather. However, these workers do get some nutrients from the juices in the plants they harvest. Other workers meet the collectors at the nest entrance and accept the harvested plant materials. The workers chew the larger pieces into smaller pieces. The small pieces mix with the ants saliva to produce a moist substance that is deposited into special parts of the nest called fungus chambers. As the fungi in the fungal chambers grow and reproduce, enzymes are secreted ...
The Argentine ant, Linepithema humile, is a widespread invasive ant species that has successfully established in nearly all continents across the globe. Argentine ants are characterised by a social structure known as unicoloniality, where territorial boundaries between nests are absent and intraspecific aggression is rare. This is particularly pronounced in introduced populations and results in the formation of large and spatially expansive supercolonies. Although it is amongst the most well studied of invasive ants, very little work has been done on this ant in South Africa. In this first study, we investigate the population structure of Argentine ants in South Africa. We use behavioural (aggression tests) and chemical (CHC) approaches to investigate the population structure of Argentine ants within the Western Cape, identify the number of supercolonies and infer number of introductions. Both the aggression assays and chemical data revealed that the Western Cape Argentine ant population can be divided
Fire ant (Solenopsis invicta) queens founding a colony with unrelated nest mates potentially face a trade-off. Increased individual investment enhances worker production, colony survival, and growth. However, increased investment may reduce a queens probability of surviving fights that invariably arise after worker eclosion. Indeed, previous studies showed that queens lose less weight (a measure of investment) when initiating colonies with cofoundresses than when alone, and that within associations the queen losing more weight is more likely to die. In this study, we tested whether queens adjust weight loss to social environment and fighting ability and whether restraining weight loss directly increases survival prospects. Experimental manipulation of colonies showed that reduced investment by queens within associations is primarily a response to the presence of a nest mate and not simply a response to per-queen brood-care demands. Differences in head width were associated with relati

Leafcutter ants, signature denizens of New World tropical forests, are unique in their ability to harvest fresh leaves to cultivate a nutrient-rich fungus as food.. Now, this mutualism -- a complicated interplay of ants, fungi and a suite of bacteria -- is coming into sharper focus as a team of University of Wisconsin-Madison researchers has published the complete genome of the leafcutter ant, Atta cephalotes.. The study, published today (Feb. 10, 2011) in the journal Public Library of Science (PLoS) Genetics, by an international team led by UW-Madison bacteriology professors Cameron Currie and Garret Suen, illustrates how lifestyle can remake an animals genetic blueprint over the course of evolutionary history.. The genome, the first for a leafcutter ant, reveals that the insect has shed genes that other ant species use to help acquire nutrients. The leafcutter, which cannot survive without its fungus food, has apparently slimmed its genome to get rid of genes it no longer needs due to its ...

The target of this fiasco was the red imported fire ant (Solenopsis invicta), which had been introduced into the port of Mobile, Alabama, most likely in cargo shipped from Argentina. Its colonies, each containing several hundred thousand very aggressive workers, construct soil nests surmounted by mounds as much as a foot high. The name fire ant comes from its sting, which feels like a burning match held too close to the skin. The exact time of the establishment of the species in the United States is not known, but was probably sometime in the 1930s. By rare coincidence I was the first person unofficially to record its presence. In 1942, as a thirteen-year-old Boy Scout studying ant species around my home near the Mobile docks, I discovered a single well-developed colony of red imported fire ants. Seven years later, when the species had become abundant enough to rank as a local pest, I was hired by the state of Alabama to make the first thorough study of its habits and distribution. I found that ...
Background (−)-Solenopsin A is a piperidine alkaloid that is a component of the venom of the fire ant Solenopsis invicta. Previously, we have demonstrated that solenopsin exhibit anti-angiogenic activity and downregulate phosphoinositol-3 kinase (PI3K) in the p53 deficient renal cell carcinoma cell line 786-O. Solenopsin has structural similarities to ceramide, a major endogenous regulator of cell signaling and cancer therapy induced apoptosis. Methods Different analogs of solenopsin were synthesized in order to explore structure-activity relationships. The anti-proliferative effect of solenopsin and analogs was tested on six different cell lines, including three tumor cell lines, two normal cutaneous cell lines, and one immortalized hyperproliferative cell line. FRET-based reporters were used to study the affect of solenopsin and analogs on Akt activity and PDK1 activation and sucrose density gradient fractionation was performed to examine recruitment of PTEN to membrane rafts. ...

In 2 to 5 years, a colony with a good supply of food may form a reproductive or dispersal generation. This generation consists of winged males and females. Males are about 5/8 inches long; winged females are 5/8 to 7/8 inches long. Most males, whose only purpose is to fertilize the females eggs, die shortly thereafter. The females shed their wings immediately after mating and become full-fledged queens. In Maine, a 3/4 inch long, wingless ant is probably a queen carpenter ant. They look for wet, rotten wood in which to start new colonies or join an existing one. The queen that starts a new colony lays about 30 eggs and cares for the larvae until they are adult workers. This new generation of workers takes over the various chores in the colony and the queens full-time job becomes egg laying.. The forest is the carpenter ants natural habitat. Any wet, rotten wood attracts a new queen. Carpenter ants infest live, dead or fallen trees wherever there is some rot and moisture. In nature, they play ...
The social Hymenoptera have distinct larval and adult stages separated by metamorphosis, which implies striking remodeling of external and internal body structures during the pupal stage. This imposes challenges to gut symbionts as existing cultures are lost and may or may not need to be replaced. To elucidate the extent to which metamorphosis interrupts associations between bacteria and hosts, we analysed changes in gut microbiota during development and traced the transmission routes of dominant symbionts from the egg to adult stage in the leaf-cutting ants Acromyrmex echinatior and Atta cephalotes, which are both important functional herbivores in the New World tropics. Bacterial density remained similar across the developmental stages of Acromyrmex, but Atta brood had very low bacterial prevalences suggesting that bacterial gut symbionts are not actively maintained. We found that Wolbachia was the absolute dominant bacterial species across developmental stages in Acromyrmex and we confirmed that Atta
Studies in almonds and citrus demonstrate Altrevin fire ant bait can kill 90 percent of a fire ant population in just seven days while providing up to eight weeks of control after application.1. Altrevin fire ant bait is an excellent new tool for almond and citrus growers fighting the many problems fire ants cause, said Steven Broscious, Technical Market Manager, BASF. The insecticide has demonstrated the ability to eliminate fire ant activity in as few as seven days, compared to the current market leader, which can take two months to impact the colony. Altrevin fire ant bait represents the continuous focus from BASF to bring targeted new tools to the specialty market. Fire ants cause a number of issues for growers, such as reducing yields. According to the University of California, even a mild fire ant infestation can cost an almond grower $102.30 per acre in just 14 days.2 Fire ants also pose a risk to workers; their bite is strong, painful, and, in rare cases, has the power to kill those ...
The first thing you notice is a crumb from your midnight cherry pie raid has sprouted legs and is moving across the kitchen counter. What was last nights cast off is now a feast for a family of ants. Ants can be common pests in homes. Damage from ants varies. Most ants are primarily a nuisance and cause little damage. Carpenter ants can weaken wood in structures. However unlike termites ants nest in wood but do not eat wood. Generally there are no disease problems associated with ants. Ants have a wide range of nesting habits and food preferences. Proper identification is important in determining control measures. Some ants build nests in soil producing characteristic mounds while others nest in homes behind moldings, baseboards, countertops and similar places. Still others like carpenter ants nest in decaying or moisture damaged wood. Ants feed on a variety of foods including starches, meats, fats and sweets. Thats why they hang out in the kitchen with us. Not all ants found outdoors become ...
Some species of ants possess an unusual form of social organization in which aggression among nests is absent. This type of social organization, called unicoloniality, has been studied in only a handful of species and its evolutionary origins remain unclear. To date, no study has examined behavioural and genetic patterns at points of contact between the massive supercolonies that characterize unicoloniality. Since interactions at territory boundaries influence the costs of aggression and the likelihood of gene flow, such data may illuminate how supercolonies are formed and maintained. Here we provide field data on intraspecific territoriality for a widespread and invasive unicolonial social insect, the Argentine ant (Linepithema humile). We observed abrupt and well-defined behavioural boundaries at 16 contact zones between three different pairs of supercolonies. We visited nine of these zones weekly during a six-month period and observed consistent and intense intercolony aggression that ...

From the modern revision of the genus by Alex Wild (2007): In subtropical South America, Linepithema ants are found near sea level in rainforests, scrub forests, and floodplains. In the Central Andes they ascend to 4,000 meters elevation. In northern South America, Central America, and the Caribbean Linepithema species are more typically montane, sometimes occurring locally at high densities to the apparent exclusion of other ant species. Two species, Linepithema humile and the Argentine ant Linepithema iniquum, have been carried around the world with human commerce, although L. iniquum seems to establish only in greenhouses (Wheeler 1929, Creighton 1950). Although Linepithema ants are often observed in undisturbed primary habitat, most species may also readily be found in pastures, lawns, roadsides and other disturbed habitats, suggesting that populations weather deforestation and habitat modification reasonably well. Some species, including the notorious Argentine ant, likely thrive with ...
Fire ants are no fun! They are bothersome to your family and pets and can sting when their mounds are imposed upon. Usually fire ant stings will cause only a raised welt, but the stings can be more serious to a small percentage of people.. Fire ants are small, yellowish-red to black in color, aggressive, vicious and known for their painful burning sting. They prefer to live outdoors and are often found around sidewalks, next to homes and under trees and shrubs. Disturb a fire ant mound and they will swarm out by the hundreds to sting any person or animal perceived as a threat.. Fire ants are social creatures with defined responsibilities in their colonies.

The name army ant (or legionary ant or marabunta) is applied to over 200 ant species, in different lineages, due to their aggressive predatory foraging groups, known as raids, in which huge numbers of ants forage simultaneously over a certain area. Another shared feature is that, unlike most ant species, army ants do not construct permanent nests: an army ant colony moves almost incessantly over the time it exists. All species are members of the true ant family, Formicidae, but several groups have independently evolved the same basic behavioral and ecological syndrome. This syndrome is often referred to as legionary behavior, and may be an example of convergent evolution. Most New World army ants belong to the subfamily Ecitoninae, which contains two tribes: Cheliomyrmecini and Ecitonini. The former contains only the genus Cheliomyrmex, whereas the latter contains four genera: Neivamyrmex, Nomamyrmex, Labidus, and Eciton. The largest genus is Neivamyrmex, which contains more than 120 ...

In fact, if there are ants at your place, you find that these ants can greatly affect your home and life.. Ants may not be as dirty as rats or cockroaches but the fact that they can contaminate your food and spread germs remains. Ants live to forage and when there are ants in your house; they would get to your food one way or another. If you can prevent this, then you should. If ants get to your food, they may end up leaving their droppings or contaminate it. Sometimes, this contamination would affect the quality of your food or ingredient. In the worst case scenario, you might end up suffering from diarrhea because of the contaminants ants may leave behind.. Some particular type of ants brings potential danger to your homes. These types of ants are ...
I had to remove some insulation along the foundation wall in the basement to allow the exterminator to spray for carpenter ants (an annual event), now I need to replace it. I was considering using foam/spray insulation but I dont know if this will give those nasty buggers a nicer home. We had found that carpenter ants set up a nice metropolis inside garage door panels stored in our barn (they dug through the internal styrofoam and set up shop). Does anyone have suggestions that address insect infestation???? Thanks for any advice. I appreciate all your knowledge and humour. Normwantabe
How to Identify Carpenter Ants. Carpenter ants play key ecosystem roles, particularly by aiding in the decomposition of decaying trees. They also can infiltrate homes and other buildings, nesting in moist, rotting wood and causing...
The ant Cataglyphis lives in the Sahara desert and is one of the most thermotolerant land animals known. It forages at body temperatures above 50 degrees C, and the critical thermal maxima are at 53.6 +/- 0.8 degrees C for Cataglyphis bombycina and 55.1 +/- 1.1 degrees C for Cataglyphis bicolor. The synthesis and accumulation of heat shock proteins (HSPs) were analyzed in Cataglyphis and compared to Formica, an ant living in more moderate climates, and to two Drosophila species. In Cataglyphis, protein synthesis continues at temperatures up to 45 degrees C as compared to 39 degrees C for Formica and Drosophila. The two Drosophila species, Drosophila melanogaster and Drosophila ambigua, differ with respect to their maximal induction of HSP synthesis and accumulation by 3-4 degrees C. In contrast, the two ant species accumulate HSPs prior to their exposure to heat, and in Cataglyphis the temperature of maximal HSP induction by de novo protein synthesis is only 2 degrees C higher than in Formica. ...
Probably gyne polymorphism is not rare in Cardiocondyla, but undetected in many species because of the small available sample size. It is expressed by strong variation in mesosoma dimensions and weak differences in postocular distance (a result of larger eye size of the flying macrosomatic gynes), whereas other characters are equal. Thus, gyne polymorphism in Cardiocondyla deviates from gyne polymorphism in Leptothorax, Tetramorium, Messor, or Myrmica in which measurements of all body parts differ between micro- and macrogynes. Hence, the use of the terms macro- and microgynes is problematic in Cardiocondyla; instead the terms macro somatic and microsomatic gynes are used here. Gyne polymorphism was observed in Cardiocondyla ulianini (see also Marikovsky & Yakushkin 1974), Cardiocondyla batesii, Cardiocondyla bicoronata, Cardiocondyla nigra, Cardiocondyla elegans, and Cardiocondyla sahlbergi. All these species are inhabitants of Palaearctic deserts, semi deserts or dry steppes and three of them ...
Ants are social insects, related to wasps and bees. Ants evolved from wasp-like ancestors 110 and 130 million years ago and diversified after the rise of flowering plants. More than 12,500 out of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and a distinctive node-like structure that forms a slender waist. A few ants classified as pests include the pavement ant, yellow crazy ant, sugar ants, the Pharaoh ant, carpenter ants, Argentine ant, odorous house ants, red imported fire ant and European fire ant.. Ants are some of the strongest creatures comparative to their size. It has been documented that the common American field ant has joints that can withstand 5000 times its own body weight.. Most ants are harmless, although there are a few dangerous varieties. Fire ants are a kind of wingless wasp that has been known to kill humans. Velvet ants, which are also wingless wasps, are said to have one of the most painful stings in all of ...

Growing up in New Mexico, I was always quick to point out a film that was set, but not made, in my adopted state, called Them! The basic plot is that the early atomic tests conducted in New Mexico had caused ants to grow monstrously huge, and quite loud and noisy for never-heard ants.. I thought of that film again when Vicki Lawrence sent me an email with pictures of a giant ant. Now in comparison, this ant is nowhere near the mutant giants of Them! but compared to our tiny Argentine ants, its pretty darn large, about a half inch.. Vicki wondered if the ant was a local guy or one that had perhaps hitched a ride into the state and somehow ended up in her hallway.. The ant is a carpenter ant, the largest such ant that we have in California. Although its called a carpenter ant, it doesnt eat wood, it just builds its nest in rotting trees, old stumps, firewood and, if youre unlucky, inside any rotted or partially rotted wood in and on your house.. Seeing one in our house isnt reason to ...
Proposal to Create a Ant-Libraries Sub-Project in Apache Ant ============================================================ (0) rationale Ant itself has accumulated lots and lots of tasks over time. So many, that Ant developers have become reluctant to adding new task. Furthermore any new task in Ant would be tied to Ants release schedule which is too slow for a thriving, fresh piece of code. The proposal allows Ant tasks and types to be developed under the Ant umbrella by Ant developers but have much shorter release cycles than Ant itself. In addition it would new committers who would have commit access to a single Ant library instead of the whole of Ant. (1) scope of the subproject The subproject shall create and maintain libraries of Ant tasks and types. Each library will be managed in the same manner as the Ant project itself, the PMC is ultimately responsible for it. Common Java libraries that only happen to provide Ant tasks as well are out of scope of the subproject. Providing the tasks or ...

European fire ants are a nuisance pest for people and a potential threat to the environment. They aggressively defend their territory and readily sting humans, pets and livestock that have the misfortune to move slowly or rest within the ants large foraging areas.. The severity of reaction to the European fire ant sting varies from one individual to another, and with the location of the sting. Usually a sting results in an inflamed red area from one to four inches in diameter, sometimes with a raised white area in the center. The sting causes an initial burning sensation and the affected area can remain sore for just a few hours, or a day or more.. Where this insect has established nests, homeowners have reported that they are unable to use their yards and gardens because of repeated stings by the ants.. If European fire ants move into new places, they may threaten native species of ants. In Europe, it is believed that competition with other native ants prevents the European fire ant from ...
Trophallaxis between individual worker ants and the toxicant load in dead and live Argentine ants (Linepithema humile) in colonies exposed to fipronil and hydramethylnon experimental baits were examined using accelerator mass spectrometry (AMS). About 50% of the content of the crop containing trace levels of 14C-sucrose, 14C-hydramethylnon, and 14C-fipronil was shared between single donor and recipient ants. Dead workers and queens contained significantly more hydramethylnon (122.7 and 22.4 amol/μg ant, respectively) than did live workers and queens (96.3 and 10.4 amol/μg ant, respectively). Dead workers had significantly more fipronil (420.3 amol/μg ant) than did live workers (208.5 amol/μg ant), but dead and live queens had equal fipronil levels (59.5 and 54.3 amol/μg ant, respectively). Moreover, the distribution of fipronil differed within the bodies of dead and live queens; the highest amounts of fipronil were recovered in the thorax of dead queens whereas live queens had the highest ...
Apache Ant is a Java library and command-line tool whose mission is to drive processes described in build files as targets and extension points dependent upon each other. The main known usage of Ant is the build of Java applications. Ant supplies a number of built-in tasks allowing to compile, assemble, test and run Java applications. Ant can also be used effectively to build non Java applications, for instance C or C++ applications. More generally, Ant can be used to pilot any type of process which can be described in terms of targets and tasks. Ant is written in Java. Users of Ant can develop their own antlibs containing Ant tasks and types, and are offered a large number of ready-made commercial or open-source antlibs. Ant is extremely flexible and does not impose coding conventions or directory layouts to the Java projects which adopt it as a build tool. Software development projects looking for a solution combining build tool and dependency management can use Ant in combination with ...
Broadcast baiting is the first secret to fire ant control. The bait should have Hydramethylnon, and its important for it to contain a fire ant killer. You can treat a specific area with a hand-held scoop. Focus on areas where fire ant mounds form. You know that there are fire ants in an area if there are granules spreading on the ground.. Do this late in the afternoon to early evening, and as often as once or twice a season. Broadcast baiting during the fall will lead to the reduction of fire ant population during the spring. If you do not know a brand, you can try the popular MaxForce for outdoor use, but make sure that you do not use this before it rains.. ...
Ant assemblages are almost all related with the vegetation composition and so can provide us important information for conservation strategies, which are especially relevant to an environmentally protected area. We sampled the ant fauna in three different phytophysionomies in order to verify if the composition of ant species is different among the areas, especially because one of the areas is a Rocky Field and there is little information about the ant fauna in this habitat. A total of 8730 individuals were registered and an NMDS analysis showed that the ant assemblies are different at the three phytophysionomies (Rocky Field, Riparian Forest, and Secondary Forest). This study shows that the species that compose the ant assemblies in different phytophysionomies are a reflex of the environment, supporting the hypothesis that the vegetational composition results in different compositions in the ant assembly. Vegetal composition is determinant in the formation of the litter and consequently in the

Grass-cutting ants (Atta vollenweideri) carry fragments that can be many times heavier and longer than the ants themselves and it is important for them to avoid falling over during load transport. To investigate whether the energetic costs of transport are affected by the need to maintain stability, the rate of CO2 production was measured in both unladen workers and workers carrying standardized paper fragments of different size and shape. We tested: (1) the effect of mass by comparing workers carrying either light or heavy fragments of the same size, and (2) the effect of shape by comparing short and long fragments of the same mass. Consistent with previous studies, metabolic rate increased but running speed remained constant when ants carried heavier fragments. The net cost of transport (normalized to the total mass of ant and fragment) was the same for heavy and light fragments, and did not differ from the costs of carrying a unit body mass. Ants carrying long fragments showed similar ...

But for that reason, I only put out baits when I have an ant problem, when theyre gone I throw them away. Ive tried all the natural ant remedies, and in my opinion, theyre all a big fail.

The team used Formica fusca, an ant species that can form thousand-strong colonies. This common black ant eats other insects, and also aphid honeydew. It often nests in tree stumps or under rocks and foraging workers can sometimes be spotted climbing trees.. Some ants were infected with Beauveria bassiana, a fungus. Infected ants chose food laced with toxic hydrogen peroxide, whereas healthy ants avoided it. Hydrogen peroxide reduced infected ant fatalities by 15%, and the ants varied their intake depending upon how high the peroxide concentration was.. In the wild, Formica fusca can encounter similar chemicals in aphids and dead ants. The Independent reported self-medicating ants a first among insects..

The phorid fly, Pseudacteon tricuspis Borgmeier, is an introduced parasitoid of imported fire ants, Solenopsis spp., in the USA. Although the assumption that phorid flies use fire ant alarm pheromones for host location is probably true, we demonstrated in a previous study the possible involvement of other ant semiochemicals in the response of P. tricuspis to fire ants. This study was conducted to determine the glandular sources and identity of the semiochemicals mediating this interaction. First, we tested the electroantennogram response of P. tricuspis to extracts of key body parts and glands of workers of the red imported fire ant, S. invicta Buren. The results confirm that the poison (venom) gland/sac is the key source of compounds which elicited strong antennal activity in P. tricuspis. Follow-up studies were conducted by using a combination of bioassay-guided fractionation and behavioral bioassays to test the hypothesis that attraction of this parasitoid to fire ants is mediated by venom alkaloids.

N2 - Background The ant species Pachycondyla chinensis, which has spread from Far Eastern Asia to New Zealand and North America, induces anaphylactic reactions in human with its sting. However, the major allergens of P. chinensis have not yet been characterized. Methods We selected seven patients with histories of anaphylaxis induced by P. chinensis. Two-dimensional electrophoresis (2-DE) was used to identify the major allergens. We subsequently performed Western blots for P. chinensis-specific IgEs, N-terminal amino acid sequencing, ESI-MS/MS, and RT-PCR using primers based on the N-terminal sequence. Results Six of the anaphylactic subjects had an IgE specific to a 23 kDa allergen of P. chinensis. Two ...
Learn about little fire ants, including how to identify them versus other species of ants, how they can be a threat to your home and tips for control.
Crowded house. Most ant colonies live in nests on or under the ground or in trees, but some ant species live in clusters, not building any nests at all. Most ant colonies have a queen, large numbers of female worker ants, and occasionally some males. The queens only job is to lay eggs, and this she does throughout her entire life. But how does she begin her reign?. Queen for a day (or much longer). A young winged queen leaves her birth colony on her first and only flight with a number of winged males. Males are only produced for mating purposes and do no work other than to fertilize virgin queens. Mating flights typically include neighboring ant colonies, and the signals for this coordinated nuptial swarm are still not fully understood. After the queen and males mate, the males die. The young queen now finds a good site to make her nest and start her colony. She rakes the wings off her body, as she no longer needs them for her new life. The queen begins her new colony there, laying eggs and ...
In tropical areas, there are many different species of ants that live exclusively in the tree crowns. They do not come down to the ground and therefore cannot get nutrition there. This applies, for example, to weaver ants that live in the crowns of many different trees and bushes - including coffee trees. Each tree can have up to 60,000 ants.. In the laboratory, the researchers built a mini-coffee plantation with several individual coffee trees. The central coffee tree held a colony of weaver ants.. All the coffee trees were placed in water, so the ants could not move from tree to tree unless there was a bridge to take them across. To allow them to move between trees, the researchers built suspension bridges between some of the trees.. On the central tree, the ants were fed with an amino acid - glycine. The researchers were able to follow the labeled nitrogen in the neighboring trees to which the ants walked over via the suspension bridges.. ...
2. Make bait dispensers out of old plastic containers with lids. Punch holes in them so the ants can get inside, then put the soaked cotton balls into the containers and cover them with lids so the bait wont dry out.. 3. Place the bait containers wherever you see ant trails, in or outside the house.. 4. Clean the containers and use fresh bait solution at least once a week.. 5. Be patient! The key is to get worker ants to continually carry low doses of boric acid back to feed the ants in their nest. Boric acid is mildly repellent to ants, and using a very low dose makes it more likely that surviving ants will continue eating the bait and taking it back to the nest.. ...

Army ants can be roughly divided between species that forage above ground (epigaeic forms) and those that forage subterraneously or beneath leaf litter (hypogaeic forms), though some hypogaeic species will forage epigaeically if conditions permit (usually at night). Similarly, epigaeic foragers may in turn be either epigaeic or hypogaeic nesters. For obvious reasons, the epigaeic species are the best studied with little being known about the sociobiology of most hypogaeic species; however, it is the hypogaeic forms that account for the majority of army ant species. In all army ants studied to date, foraging is done by advancing columns or networks of groups of workers, without individual exploratory scouts searching ahead for food sources. Location of food sources is therefore largely fortuitous, though advancing columns are attracted to movement (potential prey animals have been observed avoiding predation by the simple expedient of not moving). In the subterranean forager Dorylus laevigatus, ...
This chapter highlights the severity of problems that the red fire ant caused and the opinions that clustered around the belief that the ant was a pest to be dealt with. This chapter also explains that the insecticides used to kill it were either a threat to other forms of life or were used with little regard for consequences. The ant changed its behavior in some areas where it had long been established, its density also declined along with its tendency to attack crops and vertebrates. During the same time, the insecticides were following their own natural laws, killing ants and songbirds. All these events were observed by people who had different standpoints who therefore interpreted these changes differently. The opinions of both the conservationists and environmentalists about the insect, the insecticides, and the eradication program surfaced from an interaction between the natural world and the ideas of those who represented different interests in American society. ...
The toxicology of red imported fire ant venom has been extensively studied. The venom is important to the red imported fire ant, enabling it to capture its prey and to defend itself. Some 14 million people are bitten annually in the United States, suffering reactions including sensitivity and anaphylactic shock. The venom contains some 46 proteins of which four are allergens. Venom plays an important role in a red imported fire ant colony, being used to capture prey items, for defence, and antimicrobial action. On average, however, a worker produces very little venom (less than 1 µg/kg). Newborn workers contain little to no venom within their reservoirs, but workers that are only one-day old can produce 1.17 µg/kg. However, workers that are 15 days old only produce 0.3 µg/kg. Workers deliver 0.66 nl of venom when they sting, which amounts to 3.1% of their supply. Older workers deliver less venom when they sting, but middle-aged workers and nest-defenders deliver much higher quantities. Like ...
We studied the relationship between Hirtella myrmecophila (Chrysobalanaceae), a common but little-studied Amazonian ant-plant that produces leaf-pouches as domatia, and its obligate ant partner, Allomerus octoarticulatus. Field observations revealed that H. myrmecophila drops domatia from older leaves, a characteristic that is unique among myrmecophytes. The physiological mechanism for abortion of domatia is currently unknown, but this characteristic allows for the existence, within the same plant, of branches with and without ants. Older branches generally bear only old leaves with no domatia and therefore have no ants, whereas younger branches have leaves of various ages. Ants forage mainly on new leaves, and experimental removal of ants showed that A. octoarticulatus is crucial for defense of these leaves against insect herbivores. However, A. octoarticulatus also acts as a castration parasite, severing the plants inflorescences. Mature flowers and fruits were only found on older branches ...

Mutualisms, or mutually beneficial species interactions (+/+), play a key role in ecological community functioning, influencing community stability and biological diversity. Despite their importance in ecological processes, the study of mutualism has limitations. First, seemingly positive interactions are often considered mutualisms without proper evaluation of the interaction consequences to both partners involved. Second, studies on mutualism often focus on a single life history stage, yet organisms often engage in multiple forms of mutualism during their lifetime (e.g., many plants rely on pollinators and seed dispersers). My research addressed these limitations in mutualism research by investigating (1) the outcomes of interaction between an invasive plant (Euphorbia esula L., Euphorbiaceae) and the native ant community during both the seed and flowering plant stages, and (2) how both the ant and plant benefit from myrmecochory (ant-mediated seed dispersal). My research had three main ...
active much earlier inthe year than Argentine ants, getting a jumpstart on their competitors. They start to reproduce, forage for food, and build new colonies in Argentine ant territory as early as March, while the Argentine ants take another couple of months to rise and shine and get going. Finding their old territories already occupied, the Argentine ants typically move on to other areas.. In forests, Asian needle ants nest in rotting logs, under leaves and mulch, and under rocks. In human environments, they can nest anywhere from potted plants to under door mats, in landscaping materials, and even under dog bowls.. While they love to eat termites, Asian needle ants will consume just about anything it can get its mandibles around, from dead insects to other ants to human garbage. Its aggressiveness, habitat versatility and eating habits could mean a great change to our eco-systems. When these guys move in they eat other ants, devour their food sources, and take up their nesting spaces, ...

In our study, 105 of the ant colonies used were from four genera of fungus-growing ants: Apterostigma, Mycetarotes, Trachymyrmex and Acromyrmex. In each of these four genera, workers both carry an abundance of visible white bloom of Actinobacteria on their cuticle (figure 1 and electronic supplementary material, figure S1a) and are large enough to facilitate targeted isolations of localized growth of Actinobacteria. In all of these ant colonies, multiple colony-forming units (CFUs) of morphologically similar Actinobacteria (see electronic supplementary material, figure S1b-d) were obtained from ant cuticles, and sequencing confirmed that these isolates were Pseudonocardia. We also isolated Pseudonocardia from the other five genera of fungus-growing ants examined: Myrmicocrypta, Mycocepurus, Mycetosoritis, Cyphomyrmex and Atta. One, three and four colonies of Mycetosoritis, Mycocepurus, Myrmicocrypta ants were sampled, respectively, and each ant colony yielded CFUs of morphologically similar ...
Technically no. But they do undergo periods of lessened brain activity similar to what we experience at sleep. They amass into colonies at night and have this collective period. There is this parasite called the liver lancet fluke which can thrive and reproduce in sheep. The prarsite lays eggs which pass out in the sheep excrement. Snails eat the excrement and within the snail the eggs hatch into parasite organisms. These pass out in the snail slime. Heres where the ants come in. Well, ants eat the slime, and in doing so become infected with the parasite. The parasite performs some sort of host manipulation - a mind control of sorts and causes the ant to react in an odd way. Every morning, just as the sun rises (nature has a beautiful drama) - the ant awakens from its lower brain power state - its sleep (not really, but...), before the other ants, and leaves the colony. The parasite seems to activate some suicidal tendency in the ant - it causes it to climb to the very top of grass blades, ...

Happier versions of the fable show the ants taking pity and giving the grasshopper some food, on the premise that turning the grasshopper away in his time of need is also morally questionable. A prime example is the 1934 animated short subject produced by Walt Disney. The Queen of the Ants decrees that the grasshopper may stay in the ant colony, but he must play his fiddle in return for his room and board. He agrees to this arrangement, and the ant tunnels become a grand ballroom where all the ants happily dance to the music of the grasshopper, who finally learns that he needs to make himself useful. Notably, this short introduced the song The World Owes Me a Livin, which would later become a signature tune for Goofy (Pinto Colvig, the original voice of Goofy, voices the grasshopper in this version ...

A good least-toxic method is the use of boric acid baits. Boric acid baits can eliminate some ant colonies in about one week. The trick is to not kill the ants at the bait station, but to get the ants to carry the boric acid back to the nest, poisoning the members of the colony that never leave the nest. Most ants feed either on sugars or on protein, fats, or oils. To see which type you have, place small dabs of jelly and peanut butter (not mixed) where ants are seen and watch which food they are attracted to. If they are attracted to the jelly, you can make a boric acid bait by mixing one-half cup jelly, such as apple jelly, with 1 1/4 tsp boric acid powder. Punch several holes in the lid of the jar, then screw the lid on tightly and seal with tape. The holes should be large enough for the ants to pass through to reach the bait. Place the bait jar on its side where the ants will come in contact with it. If the ants are unable to gain footing on the jar lid, you might want to scratch the surface ...
The Amazonian tree known Hirtella physophora looks rather unassuming, but it is the site of several grisly spectacles. Amid its leaves and branches, an animal, a plant and a fungus conspire to create a nightmarish trap where trespassers become meals, robbers get the death penalty, and assassins are assassinated.. The tree is home to ants called Allomerus decemarticulatus, which defend it from hungry insects. In return, the tree provides the ants with leaf pouches and swollen thorns as shelter, and feeds them with nectar and sugary nodules. These food sources are rich in carbohydrates but low in proteins. To supplement their diets, the ants need flesh, and they get it by shaping the tree into traps.. The ants cut hairs from the plant and weave them together into a hollow gallery, which extends down the side of the trees branches. Within the gallery, the ants hide inside small holes, jaws agape. From the outside, nothing can see them. If an insect lands on the trap, hundreds of lurking jaws seize ...

Ants Are On My Fava Beans. What Do I Do? I planted fava beans, and I noticed that I have ants on them. How do I get rid of them without using any unnatural pesticides?
The inchman (Myrmecia forficate) is a species of bull ant that can be found in Australia, in a range that includes Tasmania and possibly southeastern areas of Australia. This species is gregarious, living in colonies like most other ant species, but it forages for food alone. Nests often go unseen and are typically found under rocks. It reaches an average body length of up to one inch long, the trait from which it received its common name.. The inchman is both a scavenger and a carnivore and it is the most poisonous species within its genus. When this species stings, it is similar the sting of a wasp or fire ant, causing anaphylaxis, which kills its prey. The first symptoms of a sting from this species include swelling and fever, with three percent of cases reporting anaphylaxis..

Ants have been known to have a positive impact on soils by mixing different layers and by adding nutrients, etc. Now a researcher from Arizona State University, Dr. Ronald Dorn, has found that ants are enhancing the breakdown of certain minerals and the movement of carbon dioxide into calcium carbonate (limestone). The bottom line: ants might be helping to remove greenhouse gases from the atmosphere.. Dr. Dorn did not start out to study ants. He actually began the study 25 years ago to look at weathering of olivine and plagioclase minerals from Hawaiian basalt. He placed samples in various sites in Arizona and Texas, and then went back every five years to see what was happening to them.. Other researchers have shown that weathering of calcium and magnesium silicates by living things is important in removing atmospheric carbon dioxide gases. A simplified reaction is shown here: ...

The ultrastructure of the fat body cells (trophocytes) of the last larval instar of Pachycondyla (= Neoponera) villosa is presented. The cytoplasm is restricted to the cell periphery and to the smaller strips among the vacuoles, protein granules, lipid droplets, and around the nucleus. Cytochemically, the presence of basic amino acids in the protein granules and in the nuclei was observed by using the ethanolic phosphotungstic acid technique (EPTA). The lipid droplets stained for unsaturated lipids. This result was further confirmed by gas chromatography and mass spectrometry, where the unsaturated fatty acids were identified as oleic and linoleic acids together with saturated fatty acids such as palmitic and stearic acid. Carbohydrates (glycogen) were also detected in the fat body. The glycogen is present as β particles distributed among the lipid droplets and sometimes attached to them.
Sex ratios in social insects have been the subject of intense study since Trivers & Hare (1976) first modified Fishers (1930) sex ratio theory to include kin selection, particularly in species with haplodiploid sex determination. Their argument made specific quantitative predictions about the investment sex ratio and predicted that it would be affected by several aspects of colony structure (mating frequency, worker reproduction, queen number, etc.). In the simplest case, a single queen that mates once, workers are predicted to bias investment in a ratio of 3 : 1 in favour of their sisters, with whom they share higher relatedness. Female-biased sex ratios have subsequently been confirmed in many social Hymenoptera (e.g. Queller & Strassmann 1998; Ratnieks et al. 2006).. When colonies are founded by multiple queens, by a multiply mated queen or when workers reproduce, the predictions about sex ratio also change. Many studies have explored the effect of mating frequency (e.g. Starr 1979; Nonacs ...
When it comes to your house and the safety of your family, youre very protective of them. Why? Because your house is expensive and your family is priceless so youll do whatever you can in your power to keep them safe. Guarding them from dangerous invaders is a priority because not only can infesting insects cause damage to your home but some of these pests can cause harm and injury to your loved ones. To protect themselves, insects use various measures of defense such as biting or stinging their victims. Below is a pest control in Bellflowers list of top 5 worst insect bites and/or stings:. Fire ants. Fire ants are an incredibly aggressive ant. They belong to colonies that can reach up to 250,000 ants and are omnivorous, eating both vegetation and meat. What these ants are known for are their bites. For most, the bite is a shocking sting followed by a red and painful welt but for a small percentage of those who are allergic, this bite can be fatal. Since these ants arent solitary, it is ...
DNA computing is a new computing paradigm which uses bio-molecular as information storage media and biochemical tools as information processing operators. It has shows many successful and promising results for various applications. Since DNA reactions are probabilistic reactions, it can cause the different results for the same situations, which can be regarded as errors in the computation. To overcome the drawbacks, much works have focused to design the error-minimized DNA sequences to improve the reliability of DNA computing. In this research, Population-based Ant Colony Optimization (P-ACO) is proposed to solve the DNA sequence optimization. PACO approach is a meta-heuristic algorithm that uses some ants to obtain the solutions based on the pheromone in their colony. The DNA sequence design problem is modelled by four nodes, representing four DNA bases (A, T, C, and G). The results from the proposed algorithm are compared with other sequence design methods, which are Genetic Algorithm (GA), ...
But the story can get more complicated. Imagine a symbiosis with four co-evolving partners: three of them are engaged in a mutualistic relationship, while the fourth one is a parasite. Thats the beautiful case of fungus-growing ants. In their underground nests, the ants grow a mushroom-like fungus by feeding it with plant materials or other organic matter. In turn, the fungus serves as food for the ants (yes, this is agriculture!). But every garden has its pests, and the ants farm is home for the Escovopsis mold. Escovopsis is a specialized pest, found only on the crop of farming ants. To battle the parasite, the ants combine special behaviors and microbial symbionts. These insects carry a bunch of antibiotic-producing actinomycetes in elaborate cuticular crypts, supported by unique exocrine glands. The symbiotic bacteria produce substances that specifically inhibit Escovopsis growth. Although initially identified as Streptomyces, the actinomycete symbionts appear to belong to the ...

The ant works hard in the withering heat all summer long, building his house and laying up supplies for the winter. The grasshopper thinks hes a fool and laughs and dances and plays the summer away. Come winter, the shivering grasshopper calls a press conference and demands to know why the ant should be allowed to be warm and well fed while others are cold and starving. CBS, NBC, ABC and CNN show up to provide pictures of the shivering grasshopper next to video of the ant in his comfortable home with a table filled with food. America is stunned by the sharp contrast. How can it be that, in a country of such wealth, this poor grasshopper is allowed to suffer so? Then a representative of the NAGB (The National Association of Green Bugs) shows up on Nightline and charges the ant with green bias, and makes the case that the grasshopper is the victim of 30 million years of greenism. Kermit the Frog appears on Oprah with the grasshopper, and everybody cries when he sings Its Not Easy Being Green. ...
156. THE GRASSHOPPER AND THE ANTS. One fine day in winter some Ants were busy drying their store of corn, which had got rather damp during a long spell of rain. Presently up came a Grasshopper and begged them to spare her a few grains, For, she said, Im simply starving. The Ants stopped work for a moment, though this was against their principles. May we ask, said they, what you were doing with yourself all last summer? Why didnt you collect a store of food for the winter? The fact is, replied the Grasshopper, I was so busy singing that I hadnt the time. If you spent the summer singing, replied the Ants, you cant do better than spend the winter dancing. And they chuckled and went on with their work. [more info ...

Researchers have discovered a social chromosome in the highly invasive fire ant that helps to explain why some colonies allow for more than one queen ant, and could offer new solutions for dealing with this pest.
The life cycle of Large Blue Butterflies. (a) The adult female, living about 5 days, lays 50-100 white eggs on the leaves and flower buds of Gentiana spp. (b) The young caterpillar bores into the plant, where it feeds on the developing seeds for 10-15 days, reaching 2% of its adult biomass. (c) The caterpillar emerges and falls to the ground, where it secretes chemicals attractive to ants of the genus Myrmica, who carry the caterpillar back to their nest. (d) The caterpillar competes with the ant larvae in the nest. Each species is capable of secreting chemicals specific to one species of ant; if carried to the wrong sort of nest it stops secreting chemicals, relying on the general smell of the nest to provoke the ants to feed it, however this is much less reliable and frequently results in the death of the caterpillar. (e) The growing ant makes vocalizations similar to the ants queen, causing it to be fed in preference to the ants own larvae. It feeds this way for 10-22 months before emerging ...
The desert ant Cataglyphis fortis primarily feeds on dead insects that are sparse and unevenly distributed in their environment. A single forager can carry a small dead insect back to the nest without aid. As dead insects are typically found as individuals and not in groups, foragers locate food as individuals, rather than cooperatively. This…
