Mosquitoes smell and avoid the insect repellent DEET
TLDR
This research shows that mosquitoes smell DEET directly and avoid it, as indicated by the evidence that mosquitoes are endowed with DEET-detecting ORNs and corroborated by behavioral bioassays.

NMR structure reveals intramolecular regulation mechanism for pheromone binding and release
TLDR
The NMR structure of BmPBPA, which consists of a tightly packed arrangement of seven α-helices linked by well defined peptide segments and knitted together by three disulfide bridges, suggests a novel physiological mechanism of intramolecular regulation of protein function.

TLDR
The rapid inactivation of pheromone, even faster than previously estimated, is kinetically compatible with the temporal resolution required for sustained odorant-mediated flight in moths.

Conformational Change in the Pheromone-binding Protein fromBombyx mori Induced by pH and by Interaction with Membranes*
TLDR
Analysis of the pheromone-binding protein from B. mori PBP in Escherichia coliperiplasm demonstrated that its tertiary structure was sensitive to pH changes and that a dramatic conformational transition occurred between pH 6.0 and 5.0.

Multifunctional communication inRiptortus clavatus (Heteroptera: Alydidae): Conspecific nymphs and egg parasitoidOoencyrtus nezarae use the same adult attractant pheromone as chemical cue
TLDR
Field experiments revealed that the synthetic pheromone rivaled 10 live males in the attraction of adults and second-instar nymphs, and captured of the egg parasitoid O. nezarae females in cylindrical sticky traps were significantly higher in traps baited with the synthetic semiochemicals than in control traps.

Crystal and solution structures of an odorant-binding protein from the southern house mosquito complexed with an oviposition pheromone
TLDR
X-ray crystallography and NMR 3D structures of OBP1 for Culex quinquefasciatus (CquiOBP1) bound to an oviposition pheromone (5R,6S)-6-acetoxy-5-hexadecanolide (MOP) complex are reported.

Pheromone Reception
TLDR
The insect olfactory system is highly selective, able to discriminate natural pheromones from molecules with minimal structural changes, and reverse chemical ecology is a new concept for the screening of attractants based on the binding ability of OBPs.

Pheromone reception in fruit flies expressing a moth's odorant receptor
TLDR
An endogenous receptor is found in one of the sensillum types on Drosophila antenna that responds to bombykol and bombyKal with sensitivity comparable to the pheromone-detecting sensilla on B. mori male antennae.
