Diptera (true flies) are among the most diverse holometabolan insect orders and were first eukaryotic order to have a representative genome fully sequenced. 110 fly species publically available assemblies many hundreds of population-level genomes been generated in model organisms Drosophila melanogaster malaria mosquito Anopheles gambiae. Comparative genomics carried out phylogenetic context is illuminating aspects biology, providing unprecedented insight into variability structure, gene content, genetic mechanisms, rates patterns evolution genes, populations, species. Despite rich availability genomic resources flies, there remain lineages which new sequencing efforts should be directed. Such would valuable families or clades that exhibit multiple origins key behaviors such as blood feeding, phytophagy, parasitism, pollination, mycophagy.

Insects rely on their sense of smell to locate food and hosts, find mates select sites for laying eggs. Use volatile compounds, such as essential oils (EOs), repel insect pests disrupt olfaction-driven behaviors has great practical significance in integrated pest management. However, our knowledge the olfaction-based mechanisms EO repellency is quite limited.We evaluated peppermint oil nine plant components Drosophila melanogaster, a model olfaction study, D. suzukii, major fruit crop pest. All volatiles, menthone, (-)-menthol, menthyl acetate, (R)-(+)-limonene, nerol, (+)-fenchone, (-)-α-thujone, camphor, norcamphor oil, elicited melanogaster dose-dependent manner. Most except also suzukii. Menthone, (R)-(+)-limonene (+)-fenchone were most potent repellents against Repellency was reduced or abolished two mutants odorant receptor co-receptor (Orco), indicating that observed (Or)-mediated. by (-)-α-thujone involves Or-independent mechanism(s).

Comparative analyses of multiple genomes are used extensively to examine the gains and losses chemosensory receptors across genus Drosophila. However, few studies have delved into functional olfactory characteristics. Here we assess function 20 species, identify describe several similar elements evolution. We document (a) minor changes in ligands based on amino acid substitutions, (b) major or perhaps entire receptor replacements, (c) that only a subject repeated changes, whereas 32 out 37 OSNs largely functionally conserved. In addition, generate robust model for identifying using genomic data comprehensive ligand-receptor combinations, which includes prediction binding pockets. Moreover, this study highlights evolution does not affect all equally, ecological, evolutionary, developmental forces repeatedly small subset available proteins.

The ability to respond chemosensory cues is critical for survival of most organisms. Among insects, Drosophila melanogaster has the best characterized olfactory system, and availability genome sequences 30 species provides an ideal scenario studies on evolution chemosensation. Gene duplications chemoreceptor genes allow functional diversification rapidly evolving repertoire. Although some genus are generalists host plant selection, rapid receptors, gustatory odorant-binding proteins, cytochrome P450s enabled diverse specializations different members genus.

Abstract The New World Screwworm fly, Cochliomyia hominivorax , is a major pest of livestock in South America and Caribbean. However, few genomic resources have been available for this species. A genome 534 Mb was assembled from long read PacBio DNA sequencing highly inbred strain. Analysis molecular evolution identified 40 genes that are likely under positive selection. Developmental RNA-seq analysis specific associated with each stage. We identify analyze the expression important host-seeking behavior (chemosensory), development larvae open wounds warm-blooded animals (heat shock protein, immune response) building transgenic strains genetic control programs including gene drive (sex determination, germline). This study will underpin future experiments aimed at understanding parasitic lifestyle screwworm fly greatly facilitate efficient systems screwworm.

Unlike D. melanogaster, which reproduces on overripe fermenting ground, prefers to lay its eggs ripening still plants. Flies locate fruit hosts by their odorant volatiles, are detected encoded a highly specialised olfactory system before being translated into behaviour. The exact information-processing pathway is not yet fully understood, especially evaluation odour attractiveness. It also unclear what differentiates brains melanogaster cause crucial difference host selection. We hypothesised that basis for different behaviours already formed at level antennal lobe neuronal responses volatiles associated with ripe fruit. thus investigated 3D vivo two-photon calcium imaging how both species odours from fruits, leaves, fermented bacteria, mixtures lobe. then assessed behavioural odours. neural reflect species-dependent shifts code.
