Binding of a fluorescence reporter and a ligand to an odorant-binding protein of the yellow fever mosquito, Aedes aegypti [v2; ref status: indexed, http://f1000r.es/4yp]

F1000Research, 2015
Odorant-binding proteins (OBPs), also named pheromone-binding proteins when the odorant is a pheromone, are essential for insect olfaction. They solubilize odorants that reach the port of entry of the olfactory system, the pore tubules in antennae and ...

Two Antenna-Enriched Odorant Binding Proteins in Dioryctria abietella Tuned to General Odorants and Insecticides

Insects, 2022
The management of forest pests has become a significant challenge, particularly for wood borers, because they spend most of the time in the trunks or cones.

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

Insect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Decoding functional specialization in G protein‐coupled receptors (GPCRs) through evolution‐guided residue profiling

British Journal of Pharmacology, EarlyView.
Background and Purpose G protein‐coupled receptors (GPCRs) are integral membrane proteins that mediate physiological processes by enabling cells to detect and respond to diverse stimuli. Although many subfamily‐specific functional hotspots have been described, the family‐wide determinants of common and subfamily‐specific functions remain incomplete ...

Odorant-Binding Proteins in Insects

, 2010
Our understanding of the molecular and biochemical mechanisms that mediate chemoreception in insects has been greatly improved after the discovery of olfactory and taste receptor proteins. However, after 50 years of the discovery of first insect sex pheromone from the silkmoth Bombyx mori, it is still unclear how hydrophobic compounds reach the ...

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

Ecological Entomology, EarlyView.
Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

A lipid‐sensitive food choice behavior influences aging outcomes from a longevity‐promoting diet

The FEBS Journal, EarlyView.
C. elegans are exposed to a variety of bacteria in their natural environment and must be able to distinguish between beneficial and detrimental food sources. We show that C. elegans exposed to the bacterium from their natural habitat, Methylobacterium, disrupts lipid homeostasis, causing worms to avoid this bacterial species and choose the laboratory ...

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Odorant Binding Characteristics of Three Recombinant Odorant Binding Proteins in Microplitis mediator (Hymenoptera: Braconidae)

Journal of Chemical Ecology, 2014
Odorant binding proteins (OBPs) are believed to be important for transporting semiochemicals through the aqueous sensillar lymph to the olfactory receptor cells within the insect antennal sensilla. In this study, three new putative OBP genes, MmedOBP8-10, were identified from a Microplitis mediator (Hymenoptera: Braconidae) antennal cDNA library ...
