Going belowground: burying anthropomorphic biases on gustation and olfaction
Frontiers in Ecology and Evolution, 2023 Chemical signaling underpins behavioral interactions among organisms in the soil. Understanding chemical communication in the soil requires a paradigm shift in methodology and perspectives compared to aboveground ecosystems because olfaction and ...

Functional neuromodulation of chemosensation in vertebrates [PDF]
Current Opinion in Neurobiology, 2014 Neuromodulation can be defined as a biophysical process that serves to modify-or modulate-the computation performed by a neuron or network as a function of task demands and behavioral state of the animal. These modulatory effects often involve substances extrinsic to the network under observation, such as acetylcholine (ACh), norepinephrine (NE ...

Potential Drivers of Successful Biocontrol: A Perspective on Parasitoids
New Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.Parasitoids are central to classical biological control, yet predicting their long‐term effectiveness post release remains challenging. In Aotearoa New Zealand, three Microctonus (Hymenoptera: Braconidae) species have been used against pest weevils, but key aspects of their biology remain poorly understood.

Brain responses to odor mixtures with sub-threshold components
Frontiers in Psychology, 2013 Although most odorants we encounter in daily life are mixtures of several chemical substances, we still lack significant information on how we perceive and how the brain processes mixtures of odorants.

Behavioral and Transcriptional Response to Selection for Olfactory Behavior in Drosophila
G3: Genes, Genomes, Genetics, 2020 The detection, discrimination, and behavioral responses to chemical cues in the environment can have marked effects on organismal survival and reproduction, eliciting attractive or aversive behavior. To gain insight into mechanisms mediating this hedonic

The Olfactory Chemosensation of Hematophagous Hemipteran Insects
Frontiers in Physiology, 2021 As one of the most abundant insect orders on earth, most Hemipteran insects are phytophagous, with the few hematophagous exceptions falling into two families: Cimicidae, such as bed bugs, and Reduviidae, such as kissing bugs.

Advanced Science, Volume 12, Issue 43, November 20, 2025.This study presents telomere‐to‐telomere genome assemblies for two populations of Larimichthys crocea. We identified centromere‐specific tandem repeats invaded by LTR/ERV1 retrotransposons, unique 5S rRNA enrichment patterns, and population‐specific structural variants. Comparative genomic analyses further reveal distinct adaptive mechanisms in the MYD

Pleiotropic fitness effects of a Drosophila odorant-binding protein
G3: Genes, Genomes, Genetics, 2022 Insect odorant-binding proteins (OBPs) are members of a rapidly evolving multigene family traditionally thought to facilitate chemosensation. However, studies on DrosophilaObp56hD.

Evolutionary Changes of GT1 Provide Insights Into the Adaptation of Butterflies to Plant Feeding
Ecology and Evolution, Volume 15, Issue 11, November 2025.We investigated the evolution of glycosyltransferase 1 (GT1) genes in 69 butterfly species to explore their association with host plant adaptation. Our results reveal frequent tandem duplications and adaptive selection in GT1s, especially in UGT33 and UGT40 subfamilies, alongside expression patterns suggesting functional diversification.

Host Transcriptomics Reveal Reduction in Defence‐Reproduction Trade‐Offs During Coinfection
Molecular Ecology, Volume 34, Issue 21, November 2025.ABSTRACT During infection, hosts may shift resources away from reproduction towards immune defence. It is unclear to what degree these costly trade‐offs can be alleviated during protective coinfections, whereby antagonism between parasites reduces disease severity. We used transcriptomics to assess the extent to which host gene expression reflected the
