Venoms from the superfamily Formicoidea, Ants. They may contain protein factors and toxins, histamine, enzymes, and alkaloids and are often allergenic or immunogenic.
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)

A spiral bacterium active as a human gastric pathogen. It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405).

Analysis of ectatomin action on cell membranes. (1/17)

Ectatomin (m = 7928 Da) is a toxic component from the Ectatomma tuberculatum ant venom containing two homologous polypeptide chains (37 and 34 residues) linked to each other by a disulfide bond. In aqueous solution it forms a four alpha-helix bundle. At concentrations of 0.05-0.1 microm, ectatomin forms channels in cellular and artificial bilayer membranes. Immunochemical analysis of the intracellular distribution of ectatomin showed that the toxin gets efficiently inserted into the plasma membrane at a concentration of 5 x 10-7 m and does not penetrate inside the cell. The effect of ectatomin on cardiac L-type calcium current was studied. Calcium currents (ICa) in isolated rat cardiac ventricular myocytes were measured using the whole-cell perforated patch-clamp technique. It was shown that ectatomin at concentrations of 0.01-10 nm inhibited ICa after a latency of few seconds. ICa was decreased twofold by 10 nm ectatomin. However, the most prominent effect of ectatomin was observed after stimulation of ICa by isoproterenol, an agonist of beta-adrenoreceptors, or forskolin, a stimulator of adenylate cyclase. At a concentration of 1 nm, ectatomin abolished the isoproterenol- and forskolin-sensitive components of ICa. The inhibitory effect of ectatomin was partially reversed by subsequent application of 2 microm of forskolin, whereas subsequent isoproterenol application did not produce the same effect.  (+info)

Ponericins, new antibacterial and insecticidal peptides from the venom of the ant Pachycondyla goeldii. (2/17)

The antimicrobial, insecticidal, and hemolytic properties of peptides isolated from the venom of the predatory ant Pachycondyla goeldii, a member of the subfamily Ponerinae, were investigated. Fifteen novel peptides, named ponericins, exhibiting antibacterial and insecticidal properties were purified, and their amino acid sequences were characterized. According to their primary structure similarities, they can be classified into three families: ponericin G, W, and L. Ponericins share high sequence similarities with known peptides: ponericins G with cecropin-like peptides, ponericins W with gaegurins and melittin, and ponericins L with dermaseptins. Ten peptides were synthesized for further analysis. Their antimicrobial activities against Gram-positive and Gram-negative bacteria strains were analyzed together with their insecticidal activities against cricket larvae and their hemolytic activities. Interestingly, within each of the three families, several peptides present differences in their biological activities. The comparison of the structural features of ponericins with those of well-studied peptides suggests that the ponericins may adopt an amphipathic alpha-helical structure in polar environments, such as cell membranes. In the venom, the estimated peptide concentrations appear to be compatible with an antibacterial activity in vivo. This suggests that in the ant colony, the peptides exhibit a defensive role against microbial pathogens arising from prey introduction and/or ingestion.  (+info)

A case of anaphylaxis by ant (Ectomomyrmex spp.) venom and measurements of specific IgE and IgG subclasses. (3/17)

Hypersensitivity to the stings of the Hymenoptera has been described since antiquity. The hypersensitive reactions to insect stings vary from minor skin reactions to severe and sometimes fatal anaphylaxis. Concerns about sting hypersensitivity have been increasing because of many incidents of allergic reactions of patients to the fire ant in the southern area of the United States as well as the harvester ant in some areas. We experienced one unique case with severe allergic reactions by ant of the Ectomomyrmex spp. of the subfamily Ponerinae, which is not a harvester ant. For three years the patient had been suffering from generalized allergic reactions such as anaphylaxis after the ant stings four-five attacks in a year. We determined that her reactions were due to specific IgE mediated type I hypersensitivity by the detection of a high level of specific IgE to the ant venom in her serum. The high level of specific IgG4 to the ant venom was also noted in her serum, however, the role of ant venom IgG4 was not clearly determined.  (+info)

Poneratoxin, a neurotoxin from ant venom. Structure and expression in insect cells and construction of a bio-insecticide. (4/17)

Poneratoxin is a small neuropeptide found in the venom of the ant Paraponera clavata. It is stored in the venom reservoir as an inactive 25-residue peptide. Here we describe both chemically synthesized poneratoxin and poneratoxin obtained by expression in insect cells. When expressed in insect cells, poneratoxin was observed attached to cell membranes. Both synthetic and recombinant ponerotoxins were soluble below pH 4.5. The structure of synthetic poneratoxin was characterized by circular dichroism and solved by nuclear magnetic resonance. In an environment imitating a lipid bilayer, at pH within the range of insect hemolymph, synthetic poneratoxin has a V shape, with two alpha-helices connected by a beta-turn. Insect larvae were paralyzed by injection of either of the purified toxins, with the recombinant one acting faster. The recombinant toxin-producing baculovirus reduced the average survival time of the insect host by 25 h compared with unmodified virus. Mass spectrometry analysis showed that the recombinant toxin has an N-terminal 21-residue extension, possibly improving its stability and/or stabilizing the membrane-bound state. The potential use of poneratoxin for the construction of biological insecticide is discussed.  (+info)

Description of an injury in a human caused by a false tocandira (Dinoponera gigantea, Perty, 1833) with a revision on folkloric, pharmacological and clinical aspects of the giant ants of the genera Paraponera and Dinoponera (sub-family Ponerinae). (5/17)

The authors observed an injury caused by the sting of a false tocandira ant in the hand of an amateur fisherman and they describe the clinical findings and the evolution of the envenoming, which presented an acute and violent pain, cold sweating, nausea, a vomiting episode, malaise, tachycardia and left axillary's lymphadenopathy. About three hours after the accident, still feeling intense pain in the place of the sting, he presented an episode of great amount of blood in the feces with no history of digestive, hematological or vascular problems. The intense pain decreased after eight hours, but the place stayed moderately painful for about 24 hours. In that moment, he presented small grade of local edema and erythema. The authors still present the folkloric, pharmacological and clinical aspects related to the tocandiras stings, a very interesting family of ants, which presents the largest and more venomous ants of the world.  (+info)

Insect venom hypersensitivity: experience in a clinical immunology/allergy service in Singapore. (6/17)

INTRODUCTION: To study the profile of patients with allergy to the venom of insect stings. METHODS: 31 consecutive cases referred to our clinical immunology/allergy outpatient service from June 1, 1998 to June 30, 2002 were reviewed. RESULTS: These patients comprised 3.5 percent of 889 cases referred during the study period. Their mean age was 28.8 +/- 10.5 (range 19-57) years and the majority were males (90.3 percent). Of these, 20 (64.5 percent) were Chinese, four (12.9 percent) were Malays and seven (22.6 percent) were of other races. 19 patients (61.3 percent) were men from the uniformed services including 12 (63.2 percent) full-time National Servicemen. 71 percent (22 patients) were stung for the first time. Urticaria (22 cases, 71.0 percent), dyspnoea (13, 41.9 percent), angioedema (12, 38.7 percent) and syncope (ten, 32.3 percent) were the most common manifestations of insect allergy. Anaphylaxis occurred in 22 (71.0 percent) cases, constituting 30.1 percent of all cases of anaphylaxis referred to our service during the study period. Although the causative insect was identified as honeybee (12, 38.7 percent), ant (four, 12.9 percent), wasp (three, 9.7 percent), and fire ant (two, 6.5 percent) by the majority of patients, ten (32.2 percent) patients were unable to identify the causative insect. The two patients stung by fire ants were Americans working in Singapore who had been stung while in the United States. Among those with anaphylaxis, honeybee, wasp and fire ant venom, for which specific immunotherapy is available, were identified as the cause in 40.9 percent, 4.5 percent, and 4.5 percent, respectively. CONCLUSION: Insect venom hypersensitivity made up 3.5 percent of allergy/immunology referrals and 32.8 percent of cases of anaphylaxis referred to our institution. The majority were military servicemen who developed allergic reactions during the course of duty. The inability to identify the causative insect in 50 percent with sting anaphylaxis limits the role of specific immunotherapy in our patients.  (+info)

Anaphylaxis caused by imported red fire ant stings in Malaga, Spain. (7/17)

A 27-year-old woman suffered from anaphylaxis after being stung by Solenopsis invicta ants while she was handling wood from South America. The patient reported no previous adverse reactions to stings by other hymenopteran species. Intradermal skin tests with hymenoptera venom (Vespula vulgaris, Polistes species, Apis melifera) were negative. Serum specific immunoglobulin (Ig) E yielded positive results for S invicta (5.28 kU/L) and negative results for A melifera, Ves v 5 and Pol a 5. Immunodetection assays showed the presence of serum IgE against the Sol i 2 allergen. The patient had probably been stung previously although inadvertently by red fire ants while she handled infested wood from South America, and precautionary measures are thus advisable when this material is to be handled. To our knowledge this is the first case of anaphylaxis from red fire ant stings reported in Europe.  (+info)

My journey to the ants. (8/17)

In this paper, I review the strange, unplanned and unexpected journey I have had with Solenopsis invicta, the imported fire ant. Through serendipity, good fortune and repeated invenomation, I have come to count as collaborators a number of entomologists, toxicologists, allergists and immunologists who have guided me on this journey to the ants. We now understand the mechanisms for the cutaneous reactions experienced by 50% of the exposed population stung per year, as well as the immunologic and toxicologic properties of the ants unique venom. Allergen immunotherapy to fire ant extracts has been demonstrated to protect patients from repeat anaphylaxis. Methods have been developed to prevent and treat massive sting attacks on frail elders, including those in residential and medical facilities. The potential beneficial effects of venom components are under investigation. And yes, the journey and the stings continue.  (+info)

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 ...

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.
Ant sting allergy in Australia is predominantly due to the Myrmecia pilosula species complex. Gel separation of M. pilosula venom is necessary so that the allergenic importance of each component can be defined by western blotting. However, previous PAGE methods produced suboptimal resolution and the components of each band were not precisely defined. Venom was resolved in both non-reduced and reduced form by one-dimensional acid urea PAGE, SDS-PAGE and two-dimensional acid urea-SDS PAGE. Resolved peptides were extracted and analysed by HPLC-MS. Acid urea PAGE and acid urea-SDS PAGE proved more effective than SDS-PAGE for resolution of peptides smaller than 10 kDa. All of the major peptides previously observed in M. pilosula venom were observed in gel resolved venom. Venom was found to primarily consist of peptides with molecular weight , 10 kDa, most of which contain disulfide bridges. SDS-PAGE of non-reduced venom clearly defined six higher molecular weight proteins between 26 and 90 kDa. An ...
Solenopsin is an alkaloid with the molecular formula C17H35N found in the venom of fire ants (Solenopsis). It is considered the primary toxin in the venom and may be the component responsible for the cardiorespiratory failure in people who experience excessive fire ant stings. Chemically, solenopsin contains a piperidine ring substituted with a methyl group and a long hydrophobic chain. Fire ant venom contains other chemically related piperidines which make purification of solenopsin from ants difficult. Therefore, solenopsin and related compounds have been the target of organic synthesis from which pure compounds can be produced for individual study. Originally synthesized in 1998, several groups have designed novel and creative methods of synthesizing enantiopure solenopsin and other alkaloidal components of ant venom. The total synthesis of solenopsin has been described by several methods. The method proposed by Bowen et al.(Figure 1) starts with alkylation of 4-chloropyridine with a Grignard ...
Venom from the giant red bull ant is helping University of Queensland scientists understand the evolution of animal toxins in work that could lead to better treatments for pain.
Insect venoms are complicated. Really complicated. You could be forgiven for thinking that it must be a relatively simple company of chemicals that makes up the painful sensation of a bee or wasp sting, but in fact a hugely complex mixture of all sorts of compounds - proteins, peptides, enzymes, and other smaller molecules - go into a small amount of venom. The range of compounds is far too vast to detail every single one - but we can examine some of the major constituents in bee, wasp, hornet and ant venom.. Well start with the venom about which we know the most - that of bees. Unlike many other insect venoms, we have a relatively good idea of the percentage breakdown of the venom of your average bee. When the bee stings, the venom is mixed with water, so the actual composition of the substance it injects into you is around 88% water and 12% venom. From this point onward, well consider the percentages of compounds purely in the venom itself.. The main toxic component of bee venom, also ...

A new sibling species of the primitive Australian ant Myrmecia pilosula has a chromosome number of n = 1. C-banding techniques confirm that the two chromosomes of workers are homologous. Males are haploid, as in other Hymenoptera, and their somatic cells contain only a single chromosome. This new species is potentially of great importance in both laboratory and field studies on gene organization.
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. ...

Allergic reactions to insect stings result from an overreaction of a childs immune system to the venom injected by the insect. After the first sting, the childs body produces an allergic substance called immunoglobulin E (IgE) antibody, which reacts with the insect venom. If the child is stung again by the same type of insect or by one from a similar species, the insect venom will interact with the IgE antibody produced in response to the previous sting. This in turn causes the release of histamine and several other chemicals that cause allergic symptoms. The sting of an insect may only cause a local response, where pain, redness, itching, and swelling are confined to the site of the sting. This type of reaction is considered normal. The normal reaction to fire ant stings is different. Clear blisters usually form within several hours then become cloudy within 24 hours. (The reaction usually presents in a ring or cluster, since a fire ant pivots and repeatedly stings. Also, fire ants travel in ...

Taxpayers pay taxes for services and I believe if selectmen Brooks took the time to look, she would find who has the responsibility to do this job. My opinion is people should not be asked to do a job they already pay to have done through their taxes! This pay it forward picture may make for a warm fuzzy feeling and a good rah rah cheerleading scenario, it is in the end, asking people to pay twice for a service and it is simply ...
Forty minutes pass. I while away the time by making panicky phone calls to our INFOSEC desk-how the hell did that macro virus get into the file on the inspectors PC? I love the smell of an enquiry in the morning-while I wait in Inspector Dudleys office, sweating bullets. Finally I hear the heart-warming song of two-tone sirens coming down the high street. Its not the warbling war-cry of police blues and twos, but the regular rise and fall of a fire engine-which means my prayers have been answered, and the Plumbers are coming, in the shape of an OCULUS truck.. From the outside it looks like a bright red Fire Service Major Incident Command vehicle, but its not crewed by Pugh, Pugh, Barney McGrew, Cuthbert, Dibble, and Grub-this ones occupants are the away team of 21 Territorial SAS, and theyre more likely to start fires than extinguish them. I watch as it drives nose-first into the police station car park and stops. Doors open and half a dozen wiry-looking guys dressed head to foot in black ...
Known History: Born in a remote location just outside of Vacuo, life was already difficult with the lack of outside support. When a group of Griffins swarmed the town when Charlene was only eight, however, things couldnt have gotten worse... She was lucky to have survived, as it was when she found the sense to run that she discovered her Semblance... which didnt, at the time, do anything more than stall just long enough for her to get past the Griffins that tried to attack. What made matters worse was when the town suddenly burst into an enormous ball of red fire for reasons that even she couldnt tell you. It IS theorized, however, that the Dust merchant visiting at the time had found the sense to gather up enough Fire Dust to wipe out every non-flammable thing in the town, not long after Charlene had gotten to cover just outside the towns now shattered borders. Knowing shed have to survive on her own, since then, shed tried every possible way to get by. Using her Semblance to perform, ...
I prefer the manga version & I think PGSM nailed it. She was serious, focused on her own interests, and had a bit of an ego - just like many Red rangers or red/fire themed Japanese superheroes and very much like every Aries I know. You can tease them about how they outwardly look, but their goals and passions are serious and self-justified. Very different from randomly grouchy gag and inconsistent character that she had in the anime. I was able to watch the original episodes with subtitles and I was always struck by how flighty unreliable she was - shed come through in the end but after her foibles put the mission in jeopardy or there was really no choice. And in the latter situation, ANY of the senshi would fight to the end and make sure to win. I think the anime episode where she stole the Moon wand was the most damaging to my younger eyes: I never looked at her favorably and I recalled how every other senshi knew she was in the wrong. Just…not the best way to showcase her. The only ...

The core utilizes a dual-density design along with a moderate differential to produce a responsive backend reaction. Bottom line is that the Red Fire Pearl Octane Carbon creates easy length down the lane with continuous backend motion that powers through the pin deck.. ...
Blue Velvet opens on a Lumberton so idyllic it seems parodic: bright flowers along a white picket fence, a radio jingle, a shiny red fire truck from which a smiling fireman waves to us, the filmgoer. An indeterminate period. Some cars and clothes are 1980s, yet fashion and music, malt shop and nightclub mike, also draw from the 1940s through 1960s. (Lynch detests 1970s design, telling Powers: The cars were pitiful. I mean pitiful. It made you ashamed.) J.G. Ballard describes the visual style as a clash between Norman Rockwells Americana and Edward Hoppers noir.. As in many Lynchian tales (Twin Peaks, Straight Story, Mulholland Drive), paradise is marred by unexpected tragedy. In Blue Velvet, a fathers heart attack draws his son, college freshman Jeffrey (Kyle MacLachlan), home to help at the family hardware store. Finding a severed ear, Jeffrey plays Hardy Boy and discovers a criminal underworld. Simultaneously fascinated and repulsed by lowlifes, Jeffreys conflicted desires pull him ...

I looked at Paraponera morphology quite extensively, and I have to say they really show a mixture of features from different subfamilies: their maxillae are very Ponerinae like; their mandibles and antennal sockets very Ectatomminae like; while the petiole and gaster has some Myrmeciinae features. Reading Bill Browns monographs, I can see why they were classified as allied to ectatommines for a long time: they were considered ponerines in the old, inclusive sense (meaning, NOT-any other derived subfamily), that had the antennal sockets NOT-together like currently recognized ponerines, and large frontal lobes. Those were ectatommines (even including proceratiines). Now, all those features happen to be plesiomorphies.. While Paraponera seems to be a real relic, in-between lineages, I am very skeptical of its current position as sister to Tatuidris (basically). Both groups are very long branches, and it seems we have the usual problem of a phylogenetic artifact. Not sure how we are going to deal ...

fire ant bites - how to treat after a month!? You can extract one lemon or lime to stop the itching and apply it on the bites. FIRE ANT BITES This information has been provided to you compliments of the American Osteopathic College of Dermatology and your physician. Tannic acid in tea has powerful anti-inflammatory properties that help to soothe inflammation and reduces the itching, pain and burning sensation that you feel around the ant bites. Typically, the first signs of an allergic reaction to ant bites occur at or around the site of the bite. For example, red ant stings may not be too big an issue to deal with, but fire ant stings will definitely have you writhing in pain and agony. We find the dark red tiny ant in South America, and throughout the southern United States, Australia, Taiwan, and the Phillipines, to name a few â most typically in sunny, sandy places. Sings of an allergic reaction to ant bites may include fever and congestion. I have maybe 3 breakouts over a week and a half. ...
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 ...
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 ...
A new incursion of fire ants has been detected near the Brisbane airport. This is a new arrival of fire ants to Australia and genetic testing indicates that the ants originated from the Southern United States and are not related to current or previous fire ants populations in Queensland.. Its likely the new fire ants arrived in freight sometime in the last two years, and thanks to a vigilant person who reported them to Biosecurity Queensland in September last year, it is believed theyve not had time to spread far. The success of the Fire Ant Program in Gladstone and the Port of Brisbane has shown that this terrible invasive pest can be eradicated, and the key is to act quickly.. According to Biosecurity Queensland, the National Red Imported Fire Ant Eradication Program could not have achieved its success to date without the ongoing awareness and vigilance from local communities. Seventy per cent of fire ant sightings in south-east Queensland are reported by the general public. We urge you to ...

Hello, I have been searching the web for ideas to kill my new fire ant problem and was suprised to see that some people believe there are No Fire Ants in Colorado. Well thats not true and my yard is proof. I moved here from Florida two years ago and know fire ants when I see them and Ive got em in Peyton, Colorado. They started three weeks ago after the rain. Thistle plants just started growing in my yard and I wanted to kill them before they grew to the humungus size they were last summer. Much to my dismay when I stomped on a few of the small plants hundreds of fire ants came running out of them. Within the past two weeks I have huge fire ant mounds around the front of my house and lots of holes in the dirt full of ants. I am concerned because they are dangerously close to six new young trees I just had planted along my dirt road driveway and they are also in the areas where my I take my dog out in the morning. I am going to poison the hell out of the entire area around my house with 7 dust ...
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.. ...

Extinguish Plus Fire Ant Bait contains both an Insect Growth Regulator and an insecticide to kill the entire colony, queen and all. Broadcast Extinquish Plus Fire Ant on yard or treat mounds individually.
If more than 5 mounds are present, then treatment should be broadcasted over the entire area. A fire ant bait or contact insecticide may be used. Fire ant baits are made up of defatted corn grit covered with insecticide and soybean oil. Before broadcasting the fire ant bait, foraging activity should be evaluated. In order to test for foraging activity, place a potato chip or hot dog next to the mound. If fire ants find the chip or hot dog within fifteen minutes, then it is an appropriate time to broadcast the fire ant bait. Fire ants will typically actively forage when the soil surface temperature is between 70 and 90° F. The delivery process of fire ant baits into the colony is so effective, that the amount of insecticide applied in an area is significantly reduced. Fire ant baits should never be watered into the soil and they should not be used if they smell rancid. Contact insecticides can also be broadcasted over the entire area and these need to be watered into the soil. One contact ...
Fire ants writhe to make unsinkable rafts - life - 26 November 2013 - New Scientist: A raft of live fire ants, on the other hand, resists and dissipates external forces equally well on all scales. The ants can act as tiny, resistive springs by flexing and extending their legs, and they break and reform connections with their neighbours to create a flow around external forces, like being prodded with sticks. Importantly, rafts of live ants are significantly more elastic than those made of flash-frozen dead ants ...

Further, these ants impact a number of things ranging from the environment and wildlife (plants and animals) as well as people, their environment and infrastructure. Read More ...
Fire ants are known for its painful sting and venom. It has replaced many native ants in areas it infests. Fire ant colonies consist of the brood (eggs, larvae, and pupae) and several castes of adults. Adults include winged males with smaller heads and darker bodies than females, red to brown winged females, one or more queens, and workers.

Fire ants may be tiny - just 1/4 inch or less in length - but if youve ever been stung by them, you know that they pack quite a wallop. They may be similar to other red or black ants in appearance, but fire ants react angrily when their nest is disturbed. The ant first bites the skin, then inserts its stinger and injects a venom. The ant can sting several times in the same area, and many ants may attack at the same time. Reaction to the stings depends on your degree of allergy, but pustules up to 1/8 inch in diameter develop on the skin within 24 hours and can be very painful and sometimes require medical attention.. In addition to being a potential health hazard to humans and animals, fire ants often create a real problem for homeowners by building their mounds in lawns and gardens. The mounds can be a foot high and can seriously damage mowers and tillers.. Fire ants have spread across much of the southern United States and continue to advance into new areas.

Interpretive Summary: Due to their aggressiveness and venomous sting, red imported fire ants are a significant threat to humans, wildlife, crops, and livestock. Bait technology is an important component in fire ant management. The success of bait technology relies greatly on our understanding on fire foraging behaviors. Ants are the only group of animals (besides humans) that can collectively transport large food items. Although these behaviors have been extensively investigated on horizontal surfaces, few studies dealt with food transport on vertical surfaces. Red imported fire ants can forage on trees. Our studies showed that fire ants can use different strategies to transport food items on tree trunks. Small food items were carried and transported by individual ants, and larger food items were either collectively and directly transported or excised collaboratively first and small particles were then transported individually or collectively. The competition and deadlocks were frequently ...
Since both pest and non-pest ant species so commonly exist in the same orchard, monitoring plays an important role in efficient ant management. In agricultural cropping environments, coarse morphological differences, such as number of nodes on the petiole, presence of a sting, and color and size provide enough information to properly identify pest and non-pest ants. Learning about foraging activity and behavior, nest location and manner in which ants deposit tailings around the entrance hole is also helpful when distinguishing different ant species.. The UC IPM link above provides descriptions and a key for identification. In addition to what is on the website, other characteristics can help in identification. For instance, during hot daytime temperatures the foraging activity of southern fire ant diminishes considerably, while that of the native gray remains high. Also, during foraging, the native gray moves in a more herky-jerkey fashion than the southern fire ant. Both the southern fire ant ...
Chronic inflammation is believed to promote cancer through cellular and genomic damage. Inflammation creates a microenvironment within the tissue that enhances cell proliferation. In 2016, American Cancer Society estimates that 1,685,210 new cancer cases are expected to be diagnosed in the United States. Cyclooxygenase (COX) is an enzyme found to play an essential role in inflammation and converts arachidonic acid to prostaglandin-like molecules. The three isomers of COX are COX-1, COX-2, and COX-3. COX-2 has been found to be up-regulated in inflammation and some cancers, such as breast cancer and prostate cancer. Tetrahydropyridines (THPs) developed by our research group were effective in inhibiting inflammation, COX, and the growth of some breast cancer cells. Previous research has shown that pharmacological activities of the THP derivatives depend greatly on the nature and position of the substituents on the THP ring structure. Here, we present the synthesis of a series of novel THP ...

ants have a skinny little waist through which their digestive tract must pass. Solid food would lodge in the bottleneck and kill the ant, so the ants cant eat solids. They can only drink.. Yet, in forgoing solid food ants miss out on all sorts of protein available in the environment. Ants must either give up protein or figure out how to convert solids into drinkable juice. Thats where the larvae come in.. Larvae are made to eat and can handle all manner of food. They consume the solids that the worker ants have brought back to the nest and, after a little digestion, pass the protein back as a liquid. Most ant species have a simple, elegant way to do this: they regurgitate for the adults when prompted. But this direct food-passing behavior only appears in the more recent ant lineages. The ancient subfamily Amblyoponinae- including Adetomyrma- diverged from the rest of the ants over 100 million years ago and couldnt inherit this sensible way of doing things.. Natural selection is a blind ...
The big-headed ant (Pheidole megacephala) is considered one of the worlds worst invasive ant species. As the name implies, its colonies include soldier ants with disproportionately large heads. Their giant, muscle-bound noggins power their biting parts, the mandibles, which they use to attack other ants and cut up prey. In a new study, researchers report that big-headed ant colonies produce larger soldiers when they encounter other ants that know how to fight back.
