New insights on repellent recognition by Anopheles gambiae odorant-binding protein 1 [PDF]

It is generally recognized that insect odorant binding proteins (OBPs) mediate the solubilisation and transport of hydrophobic odorant molecules and contribute to the sensitivity of the insect olfactory system.

Genome‐wide and gene‐specific DNA methylation across developmental stages in Pogonomyrmex californicus: A socially polymorphic ant

Insect Molecular Biology, Volume 35, Issue 3, Page 232-245, June 2026.
Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially

Odorant binding proteins : a biotechnological tool for odour control [PDF]

The application of an odorant binding protein for odour control and fragrance delayed release from a textile surface was first explored in this work. Pig OBP-1 gene was cloned and expressed in Escherichia coli , and the purified protein was biochemically

Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

Insect Molecular Biology, Volume 35, Issue 3, Page 270-283, June 2026.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...

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 ...

Comparative proteomic profiling reveals molecular characteristics associated with oogenesis and oocyte maturation during ovarian development of Bactrocera dorsalis (Hendel) [PDF]

Time-dependent expression of proteins in ovary is important to understand oogenesis in insects. Here, we profiled the proteomes of developing ovaries from Bactrocera dorsalis (Hendel) to obtain information about ovarian development with particular ...

Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism

New Phytologist, Volume 250, Issue 5, Page 3428-3443, June 2026.
Summary Most studies of the chemical ecology of plant–pollinator interactions emphasize the role of pollinator‐mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals.

Olfactory receptors for a smell sensor: A comparative study of the electrical responses of rat I7 and human 17-40

In this paper we explore relevant electrical properties of two olfactory receptors (ORs), one from rat OR I7 and the other from human OR 17-40, which are of interest for the realization of smell nanobiosensors.

Chemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality. [PDF]

Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of ...

Olfaction in mosquitoes [PDF]

Female mosquitoes are vectors of diseases, affecting both livestock and humans. The host-seeking and identification behaviors of mosquitoes are mediated mainly by olfactory cues. The peripheral olfactory organs of mosquitoes which perceive olfactory cues
