The biological olfactory system is the sensory responsible for detection of chemical composition environment. Several attempts to mimic systems have led various artificial using different technical approaches. Here we provide a parallel description and their counterparts. We start with presentation input systems, stimuli, treat interface between external world environment where receptor neurons or chemosensors reside. then delineate functions as well overall input-output (I/O) relationships. Up this point, our accounts go along similar lines. next processing steps differ considerably: whereas in biology step following “integration” “processing” neuron outputs bulb, has realizations electronic noses. For long period time, signal stages beyond i.e., higher centers, were little studied. Only recently there been marked growth studies tackling information these centers. In noses, third stage virtually never considered. review, an up-to-date overview current knowledge both fields and, first attempt tie them together. hope it will be breeding ground better information, communication, data exchange very related but so far little-connected fields.

As in other animals, insects can modulate their odor-guided behaviors, especially sexual behavior, according to environmental and physiological factors such as the individual's nutritional state. This behavioral flexibility results from modifications of olfactory pathways under control hormones. Most studies have focused on central modulation system less attention has been paid peripheral system. To understand how inputs influence detection sex pheromones insects, we turned male moth Agrotis ipsilon for which responsiveness is dependent diet reproductive hormones, juvenile hormone (JH) 20-hydroxyecdysone (20E). We demonstrated that a sugar-rich with sodium increases sensitivity receptor neurons (Z)-7-dodecen-1-yl acetate, major pheromone compound, antennal expression binding protein (PBP2) (OR3). Such also induces overexpression Methoprene-tolerant JH underexpression ecdysone 20E antennae. The diet-induced responses were maintained by treatment Cucurbitacin B, antagonist, but suppressed topic application Precocene, biosynthesis inhibitor. These findings reveal positive state enhances through actions actors moths. More broadly our study provides, first time, neuronal molecular basis dietary-dependent endocrine

Abstract Honey bees have emerged as a new model to study the gut–brain axis, they exhibit complex social behaviors and cognitive abilities, while experiments with gnotobiotic revealed that their gut microbiota alters both brain behavioral phenotypes. Furthermore, honey bee functions supporting broad range of been intensively studied for over 50 years, has experimentally characterized only recently. Here, we combined six published datasets from metabolomic analyses provide an overview neuroactive metabolites whose abundance in gut, hemolymph varies presence microbiota. Such may either be produced by bacteria, released pollen grains during decomposition or other organs response different bacterial products. We describe current state knowledge regarding impact such on function behavior further hypotheses explore this emerging field research.

Eusociality represents the higher degree of interaction in insects. This complex social structure is maintained through a multimodal communication system that allows colony members to be flexible their responses, fulfilling overall society’s needs. The plasticity supposedly achieved by combining multiple biochemical pathways neuromodulation molecules such as biogenic amines, but mechanisms which these regulatory compounds act are far from being fully disentangled. Here, we review potential function major bioamines (dopamine, tyramine, serotine, and octopamine) on behavioral modulation principal groups eusocial Hymenoptera, with special focus ants. Because functional roles species- context-dependent, identifying direct causal relationship between amine variation changes extremely challenging. We also used quantitative qualitative synthesis approach summarize research trends interests literature related amines Shedding light aminergic regulation responses will pave way for an entirely new understanding evolution sociality

Primary and secondary atmospheric pollutants, including carbon monoxide (CO), dioxide (CO2), nitrogen oxides (NOx), ozone (O3), sulphur (SO2) particulate matter (PM2.5/PM10) with associated heavy metals (HMs) micro- nanoplastics (MPs/NPs), have the potential to influence alter interspecific interactions involving insects that are responsible for providing essential ecosystem services (ESs). Given rely on olfactory cues vital processes such as locating mates, food sources oviposition sites, volatile organic compounds (VOCs) of paramount importance in insects. While gaseous pollutants reduce lifespan individual act cues, can their biosynthesis emission exert a direct effect system Consequently, air affect functioning regulated by plant-insect interactions.

Olfaction and diel-circadian rhythm regulate different behaviors, including host-seeking, feeding, locomotion, in mosquitoes that are important for their capacity to transmit disease. Diel-rhythmic changes of the odorant-binding proteins (OBPs) olfactory organs primarily accountable rhythmicity. To better understand molecular regulating nocturnal diurnal behaviors mosquitoes, we performed a comparative RNA-sequencing study peripheral brain tissues female Anopheles culicifacies Aedes aegypti. Data analysis revealed significant upregulation genes encoding: OBPs xenobiotic-metabolizing enzymes Cytochrome P450 (CYP450) during photophase aegypti dusk-transition phase culicifacies, hypothesizing possible function regulation perireceptor events sensitivity. RNA interference studies application CYP450 inhibitors, coupled with electroantennographic recordings gambiae aegypti, established plays role odorant detection antennal Furthermore, tissue transcriptome RNAi-mediated knockdown daily temporal modulation neuronal serine proteases may have crucial signal transmission, thereby affecting These findings provide rationale further explore species-specific rhythmic expression pattern neuro-olfactory encoded factors, which could pave way develop implement successful mosquito control methods.

Behavioral strategies for foraging and reproduction in the oriental fruit fly ( Bactrocera dorsalis ) are alternative options resource allocation controlled by neuropeptides. Here we show that behavioral switch between is associated with changes antennal sensitivity. Starved flies became more sensitive to food odors while suppressing their response opposite-sex pheromones. The gene encoding sulfakinin receptor 1 SkR1 was significantly upregulated antennae of starved flies, so tested phenotypes null mutants genes skr1 −/− its ligand sk ). In both knockout lines, responses shifted mating mode even when were starved. This suggests signaling via promotes mating. Further analysis mutant revealed sets odorant (OR) differentially expressed. Functional characterization expressed ORs suggested directly suppresses expression respond hormones enhancing detect volatiles. We conclude SkR1, modulating OR expressions leading altered antenna sensitivities, an important component starvation-dependent change.

ABSTRACT Eurasian spruce bark beetle Ips typographus , a natural part of forest ecosystems, is major threat to Norway forests during outbreaks. Olfaction plays crucial role in the survival and range expansion these beetles, amid disturbances climate change. As current management strategies are suboptimal for controlling outbreaks, reverse chemical ecology approaches based on pheromone receptors offer promising alternatives. While search progress, recently found chromosomal inversions indicates signs adaptation this species. Our attempts characterise one highly expressed odorant receptors, ItypOR33 located an inversion, led discovery polymorphic variants distributed with similar frequency across 18 European populations. Deorphanizing its variant ItypOR33a using Drosophila empty‐neuron system (DeNS) revealed tuned amitinol, heterospecific component spp., whereas ( S )‐(−)‐ipsenol, conspecific I. . The silico structural basis variations by predicting putative ligand‐binding sites, tunnels ligand‐receptor interactions. However, no sex‐specific differences were expression, ligand amitinol elicited behavioural electrophysiological responses. Reporting population‐level functional olfactory polymorphisms first time non‐model organism—bark provides key evidence further exploring their forests. Additionally, findings indicate potential long‐term complexities managing beetles
