Genome‐wide identification of olfactory receptor and odorant‐binding protein gene families and their roles in Heliothine chemosensory evolution

Insect Molecular Biology, Volume 35, Issue 5, Page 594-612, October 2026.
Genome‐wide systematic annotation identified 81 odorant receptors (ORs) and 49 odorant‐binding proteins (OBPs) in the tobacco budworm, Chloridea virescens. Phylogenetic analyses revealed chemosensory gene diversification in Heliothinae and extensive lineage‐specific duplications in C.

Chemical Composition and Biological Activities of Croton sertanejus Essential Oil Against Aedes aegypti and Preliminary Toxicity in Mus Musculus

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
This study investigated the chemical composition and biological potential of the essential oil from the newly described species Croton sertanejus. The results demonstrated efficacy in repellency and oviposition deterrence against the Aedes aegypti mosquito, coupled with low mammalian toxicity, suggesting the potential of this oil as a viable ...

On the Larval Sensory Organs and Central Nervous System of the Zoea 1 of the Asian Shore Crab Hemigrapsus sanguineus (Decapoda, Brachyura)

Journal of Comparative Neurology, Volume 534, Issue 9, September 2026.
We provide a description of the morphology of selected sensory organs and of the central nervous system in the Zoea 1 of the Asian shore crab Hemigrapsus sanguineus using multiple neuroanatomical methods. Our data reveal well‐developed visual and olfactory organs and complex primary sensory neuropils related to processing this input.

Development of antennal sensilla of Tetragonisca angustula Latreille, 1811 (Hymenoptera: Meliponini) during pupation

Brazilian Journal of Biology
The antennal sensilla are sensory organs formed by a group of neurons and accessory cells, which allow perception of environmental cues, which play a role as mechanoreceptors and chemoreceptors.

The Cephalic Morphology of Protopselaphus—A Phylogenetic Connecting Link in Staphylinidae (Coleoptera)

Journal of Morphology, Volume 287, Issue 9, September 2026.
The head morphology including soft tissues of an ethanol‐preserved specimen of Protopselaphus was examined using synchrotron‐µCT and SEM and interpreted with respect to their possible phylogenetic implications. Our findings strongly support the monophyly of Protopselaphinae + Pselaphinae, with adult cephalic synapomorphies including the vertical ...

Commercial permethrin elicits chemoreceptive responses on different Anopheles gambiae sensory appendages

Pest Management Science, Volume 82, Issue 9, Page 8609-8617, September 2026.
Anopheles gambiae mosquitoes exhibit takeoff responses when presented to commercial permethrin headspace. This product elicits electrophysiological activity in the antennae and tarsi. However, only the chemical information acquired from the tarsi plays a major role in the observed behavioral response.

The Sensory Equipment of Diving Lice, a Host Ecology-Based Comparative Study

Insects
Seal lice (Anoplura) parasitize amphibious hosts, such as pinnipeds, and are uniquely adapted to an oceanic environment. As obligate, permanent ectoparasites feed on the blood of their hosts and are completely dependent on them.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, Volume 82, Issue 9, Page 8132-8151, September 2026.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Functional Morphology and Ultrastructure of the Peripheral Antennal Sensillar System of Graphosoma italicum (Müller, 1766) (Insecta: Hemiptera: Pentatomidae)

Insects
The antennae of the shield bug Graphosoma italicum (Müller, 1766) were examined through scanning and transmission electron microscopy to reveal their general morphology, as well as the antennal sensilla’s distribution, size, and ultrastructure of their ...
