Abstract:
... Ants use chemical, visual, magnetic and/or solar cues during foraging activity. Orientation is important, since foragers need to return to the nest. In this study, we analyze the maze performance of the Dinoponera quadriceps using chemical and visual cues to study spatial orientation. We used a white maze with seventeen chambers and we allowed the ants to explore for ten minutes in each session. S ...

Abstract:
... In color polymorphic insects, individuals may track available habitats and select those that better match their color phenotype. This so-called habitat choice mechanism can balance the chances of survival between morphs, equalizing fitness, which can contribute to the long-term maintenance of color polymorphism in a population. We used a population of the brown-green polymorphic admirable grasshop ...

Abstract:
... Although human skin odor is thought to be the cue that anthropophilic mosquitoes use to discriminate us from other potential hosts, the precise details of how they use skin odor to find and land on a human is unclear. We found that Aedes aegypti land on a source of skin odor without a co-located visual cue. By collecting human odor on glass beads and using identical glass beads to visually conceal ...

Abstract:
... Despite living in a rural country, farmers in India face several challenges. Every year, they suffer significant losses due to agricultural insect infestation. These losses are primarily the result of inadequate field surveillance, crop diseases, and ineffective pesticide management. We need cutting-edge technology that is constantly evolving to maintain control over such major concerns responsibl ...
insectbehavior, etc ; Culex pipiens; biotypes; food choices; insect physiology; males; oviposition; pheromones; sensory system; Show all 9 Subjects
Abstract:
... Insect behaviour relies on an olfactory sensory system that controls a range of activities, from food choice and mating to oviposition, where pheromones play a central role. In Culex mosquitoes, egg-laying is accompanied by the release of mosquito oviposition pheromone (MOP), which has been shown to affect the oviposition behaviour of conspecifics. Here, we investigated for the first time the effe ...

Abstract:
... Regurgitation behavior is a defense strategy present in several insect orders where herbivorous prey may acquire secondary noxious metabolites from plants and store them to later orally excrete when threatened. Research on regurgitation has focused on its chemical composition, its relationship with diet, and its noxious effect on predators. However, virtually nothing is known about the proximal me ...
... Since predation is a strong selection pressure on prey, the later have evolved a variety of anti-predator behavior. Death-feigning is thought as one of anti-predator behaviors to escape from predation by temporarily stopping movement and appearing to be dead. Previous studies have shown that the duration and frequency of death-feigning varies with temperature. Body color may also affect those para ...
insectbehavior, etc ; Drosophila melanogaster; cluster analysis; fruit flies; glutathione transferase; insect biochemistry; models; odors; smell; topology; Show all 10 Subjects
Abstract:
... Olfaction is one of the physiological traits of insect behavior. Insects have evolved a sophisticated olfactory system and use a combined coding strategy to process general odor. Drosophila melanogaster is a powerful model to reveal the molecular and cellular mechanisms of odor detection. Identifying new olfactory targets through complex interactions will contribute to a better understanding of th ...

Abstract:
... Patch exploitation strategies have received considerable attention since the development of the marginal value theorem. As an excellent biological research object, parasitoids have been extensively studied in regard to patch exploitation, including the effect of parasitoid states. Longevity and fecundity are state-dependent traits that may affect foraging decisions, oviposition behavior and patch ...

Abstract:
... Toxic metals, such as mercury (Hg), lead (Pb), cadmium (Cd), and copper (Cu), are widespread in the biosphere, and human activities have contributed to their continuous release into the ecosystems. Metal-induced toxicity has been extensively studied in mammals; however, the effects of these metals on insects’ behavior have been explored to far lesser degree. As the main mechanism of toxicity, the ...
... Species of the genus Trichoderma sp. are used to control leaf-cutting ants. However, knowledge about the collective immune responses of ants against this antagonist is scarce. Therefore, this study assessed the frequency of hygienic behaviors deployed by medium workers of Atta cephalotes. For this purpose, suspensions of Trichoderma sp. spores were sprayed on sub-colonies composed of workers and a ...

Abstract:
... Plant–herbivore networks comprise over 40% of the global biodiversity and are negatively impacted by habitat loss and fragmentation. However, the extent to which these networks are affected by chronic anthropogenic disturbances and aridity, the most common threats to biodiversity in dry forests, remain unknown. In this study, we examined plant and insect herbivore communities and their interaction ...

Abstract:
... The 2022 Molecular Physiology volume of Current Opinion in Insect Science offers an overview of transition-metal ion (iron, copper, manganese, and zinc) biology and nonessential heavy metal ion (cadmium, lead, and methylmercury) toxicology in the model organism Drosophila melanogaster and in other insect species. An article on ticks serves as an informative evolutionary comparator for iron and hem ...
... Chemosensory proteins (CSPs) are important molecular components of the insect olfactory system, which are involved in capturing, binding, and transporting hydrophobic odour molecules across the sensillum in sensillar lymph in regulating insect behavior. This protein family (CSPs) is also involved in many other systems that are not linked to olfactory receptors in olfactory sensilla. The brown plan ...
... The nicotinic acetylcholine receptor (nAChR) subunit gene family consists of ten members in Drosophila melanogaster. The mature nAChR is a pentamer assembled from these subunits. Despite recent advances in the in vitro expression of some receptor subunit combinations (nAChR subtypes), the in vivo combinations and stoichiometry of these subtypes remains poorly defined. In addition, there are many p ...
... BACKGROUND: Photopharmacology is a fast‐growing photonics‐based technology, which realizes the high‐resolution regulation of drugs in time and space through light. The purpose of this research was to introduce photochromic groups into the isoxazoline structure to realize the regulation of γ‐Aminobutyric acid receptors (GABARs) targeting insect behavior. RESULTS: Azobenzene‐Fluralaner analogs ABF02 ...
... Recent advances in biocompatible materials, miniaturized instrumentation, advanced computational algorithms, and genetic tools have enabled the development of novel methods and approaches to quantify the behavior of individuals or groups of animals. In conjunction with technologies that allow simultaneous monitoring of neural responses, quantitative studies of complex behaviors can reveal tighter ...
... Olfaction plays an essential role in insect behavior such as host location, foraging, mating, and oviposition. The odorant receptor co‐receptor (Orco) is an obligatory odorant receptor and indispensable in odor perception. Here, we characterized the Orco gene from the oriental fruit fly, Bactrocera dorsalis (Hendel), a notorious agriculture pest. The olfactory deficiency mutants were generated by ...

Abstract:
... The most popular plant protection method is chemical; however, this is often connected with repeated treatments. Therefore, eco‐friendly strategies need to be investigated. A good alternative is to use the natural repellent properties of plants. The aims of this study were to determine how adult striped shieldbugs (Aelia acuminata L.) feeding on spring wheat plants affect the emission of volatile ...

Abstract:
... A large accumulation of several hundred actively flight-dispersing spotted lanternflies Lycorma delicatula was found on an isolated single telephone pole in a vineyard in Eastern Pennsylvania, USA. Many of the lanternflies flying across the vineyard very near to the pole turned toward and landed on it in an apparent visually mediated response to the tall vertical silhouette, whereas others flew pa ...
