Emergence of polyphagous herbivorous insects entails significant adaptation to recognize, detoxify and digest a variety host-plants. Despite its biological practical importance - since eat 20% crops no exhaustive analysis gene repertoires required for adaptations in generalist insect herbivores has previously been performed. The noctuid moth Spodoptera frugiperda ranks as one the world's worst agricultural pests. This is while majority other lepidopteran are specialist. It consists two...
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,...
The sex pheromone system of ~160,000 moth species acts as a powerful form assortative mating whereby females attract conspecific males with species-specific blend volatile compounds. Understanding how female production and male preference coevolve to produce this diversity requires knowledge the genes underlying change in both traits. In European corn borer moth, variation is controlled by two alleles an autosomal fatty-acyl reductase gene expressed gland (pgFAR). Here we show that...
Nuclear copies of mitochondrial DNA (NUMTs or pseudogenes) are known to impede the detection interspecific genetic diversity. But effect these artifacts on phylogeographic reconstruction remains under evaluated. In this study, we analysed a set 115 sequences fragment cytochrome c oxidase subunit I gene (COI) Monochamus galloprovincialis (Coleoptera, Cerambycidae) for which overlapping signals in sequencing electropherograms were observed. Comparison full and corrected 'ambiguities-free' data...
We provide a comprehensive overview of those Lepidopteran invasions to Europe that result from increasing globalisation and also review expansion species within Europe. A total 97 non-native Lepidoptera (about 1% the known fauna), in 20 families 11 superfamilies have established so far Europe, which 30 alone are Pyraloidea. In addition, 88 European 25 expanded their range around 23% these Mediterranean or Balkan origin, invading north west. Although number alien been for hundreds years, 74%...
The bitter taste, triggered via gustatory receptors, serves as an important natural defense against the ingestion of poisonous foods in animals, and increased host breadth is usually linked to increase number receptor genes. This has been especially observed polyphagous insect species, such noctuid species from Spodoptera genus. However, dynamic physical mechanisms leading these gene expansions evolutionary pressures behind them remain elusive. Among major drivers genome dynamics are...
A mitochondrial DNA (mtDNA) study, based on 43 European populations (33 of them sampled in France) Monochamus galloprovincialis, vector the pinewood nematode, and 14 its sister species sutor was realized. Sequencing 792 bp cytochrome oxidase I (COI) 521 COII genes revealed numerous ambiguities multiple nucleotide sites for half M. galloprovincialis specimens studied (44.8%). Hypotheses heteroplasmy pseudogenes (Numts) were examined. The mtDNA isolation by alkaline lysis cloning (for three...
Abstract Background The detection of environmental cues and signals via the sensory system directs behavioral choices in diverse organisms. Insect larvae rely on input from chemosensory system, mainly olfaction, for locating food sources. In several lepidopteran species, foraging behavior preferences change across larval instars; however, molecular mechanisms underlying such plasticity during development are not fully understood. Here, we hypothesize that expression patterns odorant...
Sex pheromone receptors are crucial in insects for mate finding and contribute to species premating isolation. Many have been functionally characterized, especially moths, but loss of function studies rare. Notably, the potential role development macroglomeruli antennal lobe (the brain structures processing signals) is not known. Here, we used CRISPR-Cas9 knock-out receptor major component sex noctuid moth Spodoptera littoralis, investigated resulting effects on electrophysiological...
