Napier grass, Pennisetum purpureum, is used successfully as a trap crop for lepidopterous stem borers in Africa. This paper reports on the evaluation of the suitability of Napier grass varieties as trap crops for Busseola fusca (Lepidoptera: Noctuidae). This was done through oviposition preference tests and evaluation of larval survival on different varieties. Napier grass varieties were collected from the wild, from research institutions and farmers growing them as forage crops. In multiple-choice tests with the different Napier grass varieties, differences in oviposition preference were observed. Results from two-choice tests with Napier grass and maize plants indicated B. fusca moths have no marked difference in oviposition preference. However, compared to maize, larval survival on Napier grasses was low and a rapid decline in larval numbers was observed over the first week after inoculation on the grasses. A scanning electron microscope study of trichomes on Napier grass and maize leaves was
Ovipositors of female leafminers were examined microscopically to locate and describe types of sensory receptors present. Two basic types were found: trichoid sensilla and basiconic sensilla. These receptors are believed to function as mechano- and chemoreceptors to evaluate the suitability of a host plant for feeding, oviposition, and subsequent larval development.. Two greenhouse experiments were conducted to evaluate the effects of photoperiod and application of plant growth regulators on two factors: 1) feeding and oviposition site selection and 2) spatial distribution of feeding and oviposition sites on individual chrysanthemum plants. In the photoperiod experiment, leafminers fed and oviposited more intensely on chrysanthemums grown under short days (SD) than on plants grown under long days (LD). Densities of feeding punctures and larval mines on chrysanthemums grown under SD was positively related to leaf height on the plant, and negatively related to leaf trichome density. Spatial ...
Genes required for egg laying in response to nicotinic agonists: To identify genes required for nAChR function in egg-laying cells, we assayed egg-laying behavior in levamisole-resistant mutants, which were originally identified on the basis of their resistance to the effects of levamisole on body muscle. Mutations conferring resistance to high concentrations of levamisole (i.e., 1 mm) have been identified in several genes, including unc-29, unc-38, unc-50, unc-63, unc-74, and lev-1 (Lewiset al. 1980a). All of these "strong" levamisole resistance genes affect the assembly of functional levamisole-binding receptors as assayed in vitro (Lewiset al. 1987), and three of them, unc-38, unc-29, and lev-1, are known to encode nicotinic receptor subunits (Fleminget al. 1997). Mutations in three additional genes (lev-8, lev-9, and lev-10) confer only partial resistance to levamisole (i.e., to concentrations ≤100 μm) and have no detectable effect on the biochemical properties of the receptor as assayed ...
In nature, parasitoid wasps encounter and sometimes show oviposition behavior to nonhost species. However, little is known about the effect of such negative incidences on their subsequent host-searching behavior. We tested this effect in a tritrophic system of maize plants (Zea mays), common armyworms (hosts), tobacco cutworms (nonhosts), and parasitoid wasps, Cotesia kariyai. We used oviposition inexperienced C. kariyai and negative-experienced individuals that had expressed oviposition behavior toward nonhosts on nonhost-infested maize leaves. We first observed the olfactory behavior of C. kariyai to volatiles from host-infested plants or nonhost-infested plants in a wind tunnel. Negative-experienced wasps showed significantly lower rates of taking-off behavior (Step-1), significantly longer duration until landing (Step-2), and lower rates of landing behavior (Step-3) toward nonhost-infested plants than inexperienced wasps. However, the negative-experience did not affect these three steps ...
Background Little is known about how malaria mosquitoes locate oviposition sites in nature. Such knowledge is important to help devise monitoring and control measures that could be used to target gravid females. This study set out to develop a suite of tools that can be used to study the attraction of gravid Anopheles gambiae s.s. towards visual or olfactory cues associated with aquatic habitats. Methods Firstly, the study developed and assessed methods for using electrocuting nets to analyse the orientation of gravid females towards an aquatic habitat. Electric nets (1m high × 0.5m wide) were powered by a 12V battery via a spark box. High and low energy settings were compared for mosquito electrocution and a collection device developed to retain electrocuted mosquitoes when falling to the ground. Secondly, a range of sticky materials and a detergent were tested to quantify if and where gravid females land to lay their eggs, by treating the edge of the ponds and the water surface. A randomized ...
The study of insect abundance and distribution.. I am an insect ecologist by "bent" and my students and I work on various applied and basic research areas. We generally take an individuals-process based approach to the study of insect abundance and distribution. We use various "model" systems to ask questions ranging from the effect of host chemistry on oviposition behaviour and early stage caterpillar survival, to the effects of learning on oviposition behaviour at a landscape level and the effects of climate on insect abundance. I prefer to work on Butterfly-plant interactions, particularly Monarchs and milkweeds.. A substantial amount of our applied research has been on the ecology and biology of Helicoverpa spp, the major pest of Australian field crops, and more recently Diamondback moth, a key pest of horticulture.. ...
We predicted that if maintenance of a large oviduct is energetically costly (Vézina and Williams, in press) then oviduct size should be tightly coupled to the functional demands placed on this organ (as reported for other organ systems, e.g. Diamond and Hammond, 1992; Hammond and Diamond, 1994; Hammond et al., 1996). This prediction was supported not just at the whole-organ level (e.g. rapid regression of the oviduct following last oviposition) but also at the intra-organ level, with rapid regression of the proximal sections of the oviduct even before the final oviposition. In the ∼24 h period after the last follicle was ovulated, but before this egg was laid, the proximal infundibulum/magnum and the isthmus regions decreased by 56% and 38%, respectively. Over the same period there was no change in shell gland/vagina mass, but these sections regressed by 34% in mass in the ∼24 h after the last oviposition. This maintenance of the functional capacity of the oviduct until last oviposition is ...

TY - JOUR. T1 - An innovative ovipositor for niche exploitation impacts genital coevolution between sexes in a fruit-damaging Drosophila. AU - Muto, Leona. AU - Kamimura, Yoshitaka. AU - Tanaka, Kentaro M.. AU - Takahashi, Aya. PY - 2018/9/26. Y1 - 2018/9/26. N2 - Limited attention has been given to ecological factors influencing the coevolution of male and female genitalia. The innovative ovipositor of Drosophila suzukii, an invading fruit pest, represents an appealing case to document this phenomenon. The serrated saw-like ovipositor is used to pierce the hard skin of ripening fruits that are not used by other fruit flies that prefer soft decaying fruits. Here, we highlight another function of the ovipositor related to its involvement in genital coupling during copulation. We compared the morphology and coupling of male and female genitalia in this species to its sibling species, Drosophila subpulchrella, and to an outgroup species, Drosophila biarmipes. These comparisons and a surgical ...
As discussed previously, Aedes mosquitoes do not lay eggs directly in the water. They prefer to oviposit on a moist surface near the water line. In some cases, this could be the wall of the trap itself. This is very inconvenient, as the trap wall is a large surface area that would be difficult to study (in surveillance scenarios) and sanitize (in all scenarios). Fay and Perry tested medical tongue depressors as an oviposition pad in their ovitraps. Both uncovered tongue depressors and ones covered in various materials were tested. The results showed a preference for tongue depressors covered in brown blotting paper were strongly favored.. Studies that are more recent have found that many porous materials in dark or natural colors are effective oviposition sites for ovitraps. An ovitrap can use seed germination paper, Pellon paper, brown blotting paper, cardboard or wood with much the same effect. While there is bound to be an ideal substrate for egg collection, current Zika efforts are largely ...

were studied using larvitraps and ovitraps during a research carried out by the Public Health Ministry of Salta Province, in Tartagal, Aguaray and Salvador Mazza cities, in subtropical Argentina. The A. aegypti population was active in both dry and wet seasons with a peak in March, accordant with the heaviest rainfall. From May to November, the immature population level remained low, but increased in December. Ae. aegypti oviposition activity increased during the fall and summer, when the relative humidity was 60% or higher. Eggs were found in large numbers of ovitraps during all seasons but few eggs were observed in each one during winter. The occurrence and the number of eggs laid were variable when both seasons and cities were compared. The reduction of the population during the winter months was related to the low in the relative humidity of the atmosphere. Significant differences were detected between oviposition occurrences in Tartagal and Aguaray and Salvador Mazza cities, but no ...
ADVANCES IN THE NUTRITION AND MANAGEMENT OF THE MALE AND FEMALE BROILER BREEDER R M GOUS SUMMARY Poultry nutritionists have based the feed requirements of broiler breeder hens on the principles designed for the feeding of commercial laying pullets because of the lack of information specific to these birds. The practice of restricting the feed intake of broiler breeders during both the rearing and the laying periods differs from the that of feeding commercial pullets, and was introduced as a necessity because of the rapid growth rate of broilers, but there is still debate about the reason for the benefit derived from this practice. The extent to which feed should be restricted; the optimum time of release from the restriction programme; the basis on which the amino acid requirements for maintenance and for egg output are calculated; and the optimum intake of energy .. at various stages of the produ.ction period, arc all as pects 0 f broiler breeder nutr itron that require further defi nitive ...

Literature is reviewed on the spatial distribution of the eggs and neonate larvae of codling moth on apple trees in relation to research conducted in Nelson, New Zealand. At Nelson, oviposition increased with height and was greater in the north and east of the trees and in those with greater fruit load in some seasons, which matches published reports. All publications and the research recorded high percentages of eggs laid singly within 10-15 cm of the fruit, with most eggs on leaves even within fruit clusters; oviposition on fruit clusters of different sizes was nonrandom because more eggs were laid on those with more fruit, but the aggregation of both per cluster and within clusters was even greater than that caused by the fruit number alone ...
Effects of ammonium nitrate exposure and water acidification on the dwarf newt: The protective effect of oviposition behaviour on embryonic survival
Animals can gain protection against predators and parasites by living in groups. The encounter-dilution effect provides protection when the probability of detection of a group does not increase in proportion to group size (i.e. encounter effect), so that predators do not offset the encounter effect by attacking more members of the group (i.e. dilution effect). In this paper, we propose a novel mechanism by which prey insects could gain by producing decoys that act as multiple targets for predators or parasitoids if these decoys are recognised as preys or hosts and negatively affect the patch foraging strategy of these predators and parasitoids. Such a decoy mechanism could be present in aphid colonies in which aphid exuviae are recognised and attacked by Aphidiine wasps. We conducted a behavioural study to evaluate the effect of exuviae on parasitoid patch residence time and egg allocation in experimental aphid patches with or without exuviae. We showed that exuviae are recognised and attacked at the
Many reptiles such as certain snakes and lizards lay eggs. there are also some flightless birds for example the ostrich which lay eggs.
In a laboratory study of Q. mubata fertility, Robinson (191.20) found that three egg betelT_ee may be laid after one mating but that egg fertility is considerably increased if mating occurs before each oviposition. Fertility decreases when the interval between mating and oviposition is extended. Oviposition occurs almost without exception only after a blood meal. Eggs show no alteration in fertility when maintained between 22°C. and 32°C., but at 34°C. no larvae emerge. As already stated, I.ees and Bea.ment (191.8) have stated that 45 . is the critical temperature for normal eggs._,7 Robinson recommenced a temperature of 30C. and a relative humidity of 5% in the breeding chamber for safe and speedy production. He found that a female might deposit a few eggs without a blood meal and that large females produce more than do snnll ones. The range in number of eggs per female per batch in these experiments varied from fifty to 250, with an av. erage of 170. Many females died shortly after their ...
become replete in from twenty to fifty minutes, usually in thirty to forty minutes. Males may emerge from the first nymphal molt, but usually nymphs, molt twice before becoming adults. Males and females may feed within seven days after molting. Duration of adult feeding is thirty or forty minutes. No female has oviposited within six months after the nymphal-adult molt, even though she has been with a male continuously and both have had two to six blood meals. The first egg batch follows a blood meal by about a week. The first oviposition appears to trigger a physiological release mechanism for, in several instances, three months afterwards females have deposited a fertile egg batch with or without a meal. We are at present attempting to ascertain whether the long interval between molting and oviposition is peculiar to these laboratory observations or whether it is a usual feature in our local populations.. ...
At one point during the afternoon we witnessed an interesting behavior of a male and female Comet Darner. The pair was coupled initially, then the female flew across the pond seeming to act like the other female hunting for food or an oviposition site. At the same time, the male flew several inches behind her at or just above her height of flight, which was several inches above the water. It was as if the male was guarding or protecting the female during her foray ...
The adult lifespan of a generalist secondary parasitoid at the top of an aphid-parasitoid food web tended to decrease when oviposition and larval development took place in hosts experiencing the endophyte environment. Female A. vulgaris improved their host choice with progressing age and oviposition experience through selection of more hosts from the endophyte-free environment compared with younger and less experienced females. Offspring performance in endophyte-free hosts was only improved in terms of lifespan and no effects on developmental time, sex ratio or weight were detected. Asaphes vulgaris parasitoids are long lived and synovigenic, maturing their eggs during adulthood. Under such conditions, a reduced lifespan will most likely result in a shorter reproductive time and thus reduced fitness. Similar fitness penalties of endophytes are known for predators and primary parasitoids (Bultman et al. 1997; de Sassi et al. 2006; Härri 2007). Ours is the first study showing experimentally that ...

After copulation without sperm transfer, the short-term responses are fully induced, but only for 1 day (19). Without SP transfer, oviposition is barely induced, and only on the first day (Fig. 4A). Because the expressions of ovulin and DUP99B are not affected in the SP null males (Fig. 3 C and D), these two peptides may be responsible for the weak increase in oviposition observed on the first day after a mating with SP null males. The increase in egg laying observed in females mated to these males after day 3 corresponds to the increase in egg laying also observed over the same time period in virgin females (Fig. 4A). However, in contrast to the eggs laid by virgin females, these eggs are fertilized and produce offspring (results not shown). Indeed, offspring are obtained from eggs laid many days after copulation, demonstrating that the stored sperm of the SP null males is viable and functional (Fig. 5). Receptivity is strongly reduced only in the first few hours after mating (Fig. 4B). The ...
A factor that significantly affects the percent hatch of fertile eggs and broiler performance in the field is positioning of the eggs during holding. Eggs must be incubated with the large end up; otherwise a dramatic reduction in percent hatch due to increased percent of mal-positions will occur. At the time of storage, if it is known that eggs are to be held for more than 7 days prior to setting, it is recommended to store eggs with the small end up. Then when placing them in the setter, reposition them with the large end up.. Two separate trials were conducted by the authors with more than 6,000 fertile eggs to determine the effect of egg storage position on percent of hatchability. Fertile eggs were kept for 7 days with Big End Up (BEU) or Small End Up (SEU). All eggs were obtained from the same flock, and were from the same days production. All eggs were handled, cleaned, and disinfected in an identical manner. The results are provided below (Table 3).. ...
I started my independent research group from August 2014 in the Department of Biology at the University of Miami in Coral Gables, Florida. Our fundamental goal is to understand how neurons communicate in circuits to establish an appropriate level of activity that produces a robust, stable behavior. Our approach is to analyze in detail a model neural circuit that controls egg-laying behavior in C. elegans. We are taking advantage of the optical clarity and powerful genetics in this experimental system to literally watch the activity of every cell in the circuit in behaving animals using fluorescent Ca2+ reporters, and also to manipulate their activity using optogenetic tools. Using mutations and transgenes to discover and alter molecular signaling events between cells, we are determining how the complex pattern of activity in a circuit creates a coherent, regulated behavior. We expect these studies will reveal general principles of neurotransmitter signaling and neural circuit function with ...
LIFE CYCLE Female mosquitoes lay eggs every 3rd day during their lifespan, usually in clumps of 100-300 eggs. The eggs are deposited in standing water. Mosquitoes can lay eggs in as little as I inch of water. When the eggs hatch the larvae emerge. It takes about a week for them to develop into…

The female operates by flying from flower-head to flower-head, quickly testing each one with her antennae. If nothing is detected, she will quickly fly to a nearby flower-head and start to test again. The ovipositor is stored in a sheath that is held behind her, and if she detects a target, she will quickly unsheath the ovipositor and position herself so that she will insert it in the correct direction. This unsheathing and positioning takes less than a second. She then follows the unsheathing with a series of thrusts, each a little deeper, as she reaches the target larva. This thrusting might take two or three seconds: this is the opportunity for the shot. So we have to follow the female from flower to flower and take great care to observe when she appears to be taking a little longer than usual to inspect the flowerhead: this is a sign that she might be about to deploy. Thats the clue to get close and be ready to focus. A fast-focussing lens is essential at this point, and I have my focussing ...

The under-the-leaf oviposition technique is not in the literature, so this might be one of the first times it has been observed, and certainly the first time it has been recorded. One reasonable theory is that the larvae are very aggressive with their defence reflex (a sudden whipping of the rear of the body, pulling it up into the characteristic S shape), so the Campodorus is actually protecting itself from the Nematus larvas protection reflex. This ties in nicely with the observation that the secondary parasite checks for the presence/absence of this response before it lays its own eggs from a straddle position. I suspect that the Campodorus egg subdues the Nematus larva to some extent (but why? Certainly, it differentiates an already parasitised larva from a clean one, thereby avoiding duplicate [and therefore wasteful] primary parasitisation, but it also makes it easier for the secondary parasite to detect the primary parasite and lay its own egg. A double-edged sword ...

Diagnosis_Species: C. roseum. Parasite of Meganyctiphanes norvegica eggs which have 600-700 µm in diameter (the vitellus sphere is about 300 µm of diameter). As C. affine, the parasite produces a cylindrical stalk, but then it forms a more robust disk (about 50 µm of diameter) in contact to the vitellus membrane, surrounded by refringent granulations. This disk extends inside the host cytoplasm forming 6 rounded lobes. A large feeding apparatus (100 to 120 µm large at the end of the trophont stage) is located in the central part. Maturation of the trophont does not always prevent the first egg divisions, but then cells are totally digested, visibly by osmotrophy. Rest of the maturation as in C. affine (more sporocytes and thus dinospores are produced, probably because of the larger size of the host egg).. Body_spores_length: 9 ...

There is a way that this could occur biologically, but its a stretch and a half.. First, the womb would have to be a major part of your aliens biology, because it would have to be able to accommodate all kinds of animals (I am assuming that this is just limited to animals because it would be kind of difficult for a human to give birth to a fungus or plant, etc. Also, Ill be limiting what I cover to Earth biology, because I really dont want to deal with all of the problems of xenozoology.). Then, there is the problem of actually creating the animal in the womb, because a large part of a fetuss biology is actually designated by conditions in the womb. Different chemical conditions across the womb decide what cells get produced. Additionally, there are some difficulties with actually getting nutrients to the animal and attaching it to the womb- if it even grows in the womb at all. After all, it is mostly only mammals that actually grow their young inside them, and most other animals lay eggs. ...
