The Peripheral Olfactory Repertoire of the Lightbrown Apple Moth, Epiphyas postvittana
TLDR
A transcriptomic approach is undertaken to identify members of olfaction-related genes expressed in the adult antennae of E. postvittana that provide a substantial resource for the functional characterization of this signal transduction system and the development of odor-mediated control strategies for horticultural pests.

Characterization of Odorant Receptors from a Non-ditrysian Moth, Eriocrania semipurpurella Sheds Light on the Origin of Sex Pheromone Receptors in Lepidoptera
TLDR
The results suggest that PRs for Type 0 pheromones have evolved from ORs that detect structurally-related plant volatiles in more derived Lepidoptera, which, in turn, also independently may have evolved a novel function from Ors detecting plantvolatiles.

Functional characterization of odorant receptors from Lampronia capitella suggests a non-ditrysian origin of the lepidopteran pheromone receptor clade.

Sex-biased gene expression in antennae of Drosophila suzukii.
TLDR
The molecular results demonstrated here will facilitate to find the unique chemoreception of D. suzukii, as well as on the development of new management strategies for this pest.

The Identification of Pheromone Receptors from the Lightbrown Apple Moth, Epiphyas postvittana
Endogenous insensitivity to the Orco agonist VUAA1 reveals novel olfactory receptor complex properties in the specialist fly Mayetiola destructor
TLDR
Three residues in MdesOrco, located in different transmembrane helices as supported by 3D modelling, that confer sensitivity to VUAA1 are identified, suggesting unique complex properties in M. destructor and that not all olfactory receptor complexes are “created” equal.

A Novel Fatty Acyl Desaturase from the Pheromone Glands of Ctenopseustis obliquana and C. herana with Specific Z5-Desaturase Activity on Myristic Acid
TLDR
It is concluded that desat7 represents a new group of desaturases that has evolved a role in the biosynthesis of sex pheromones in moths.

A Sex Pheromone Receptor in the Hessian Fly Mayetiola destructor (Diptera, Cecidomyiidae)
TLDR
The first functional characterization of an OR from the Cecidomyiidae is reported, extending the role of ORs as long-range sex pheromone detectors from the Lepidoptera into the Diptera.
