Abstract Insects detect their hosts or mates primarily through olfaction, and olfactory receptors (ORs) are at the core of odorant detection. Each species has evolved a unique repertoire ORs whose functional properties expected to meet its ecological needs, though little is known about molecular basis olfaction outside Diptera. Here we report pioneer analysis large array in lepidopteran, herbivorous pest Spodoptera littoralis . We demonstrate that most narrowly tuned ubiquitous plant...
Sex pheromone receptors (PRs) are key players in chemical communication between mating partners insects. In the highly diversified insect order Lepidoptera, male PRs tuned to female-emitted type I pheromones (which make up vast majority of identified) form a dedicated subfamily odorant (ORs). Here, using combination heterologous expression and vivo genome editing methods, we bring functional evidence that at least one moth PR does not belong this but distantly related OR lineage. This PR,...
Abstract Moth sex pheromone communication is recognised as a long‐standing model for insect olfaction studies, and widespread knowledge has been accumulated on this subject thanks to numerous chemical, electrophysiological behavioural studies. A key step the identification of candidate receptors, opening new routes understanding specificity sensitivity system, but only few these receptors have yet functionally characterised. In context, we aim at unravelling molecular bases reception in...
Odorant receptors (ORs) interface animals with airborne chemical signals. They are under strong selection pressure and therefore highly divergent in different taxa. Yet, some OR orthologs conserved. These ORs may be tuned to odorants of broad importance, across species boundaries. Two widely distributed lepidopteran herbivores, codling moth Cydia pomonella (Tortricidae) feeding apples pears, the African cotton leafworm Spodoptera littoralis (Noctuidae), a on foliage wide range herbaceous...
In moths, mate finding strongly rely on the detection of sex pheromones by pheromone receptors. Any modification in functional properties these receptors can have a drastic impact reproduction. course characterizing candidate noctuid moth Spodoptera littoralis, we expressed them Drosophila olfactory sensory neurons and stimulated with large panel compounds. We found that two detect (Z,E)-9,12-14:OAc, minor component female blend. Whereas SlitOR6 is highly specific to this component, SlitOR13...
Phytophagous insects use volatile organic compounds emitted by plants to orient towards their hosts. In lepidopteran pests, crop damages are caused larval stages – the caterpillars that feed extensively on leaves or other plant tissues. However, host choice has been poorly studied, and it is generally admitted where female laid eggs. The mobility of overlooked even though several studies showed they can odors change plant. Recently, a large number odorant receptors (ORs) tuned volatiles have...

We developed a method assess and improve by focusing on removal chimeric sequences. These sequences can be result faulty contigs, merging two transcripts into one.

Abstract Moth sex pheromones are a classical model for studying sexual selection. Females typically produce species-specific pheromone blend that attracts males. Revealing the enzymes involved in interspecific variation composition is key understanding evolution of these communication systems. The nature acetate esters, which prominent compounds moth blends, remains unclear. We identify degradation using two closely related species: Heliothis ( Chloridea ) subflexa and H . C. virescens ,...

Abstract Brood is critically important in social insect colonies. It carries the colony’s fitness through delivering future reproductive adults as well workers that will increase workforce. Adoption of non-nestmate brood can colony workforce but entails risk rearing unrelated sexuals or parasites. Thus, theory would predict ant evolve ability to discriminate between nestmate and alien using chemical cues displayed at brood’s surface. This appears especially true for eggs first instar (L1)...
