A carboxylesterase, Esterase-6, modulates sensory physiological and behavioral response dynamics to pheromone in Drosophila

BMC Biology, 2012
Background Insects respond to the spatial and temporal dynamics of a pheromone plume, which implies not only a strong response to 'odor on', but also to 'odor off'. This requires mechanisms geared toward a fast signal termination.

The Peripheral Olfactory Repertoire of the Lightbrown Apple Moth, Epiphyas postvittana.

PLoS ONE, 2015
The lightbrown apple moth, Epiphyas postvittana is an increasingly global pest of horticultural crops. Like other moths, E. postvittana relies on olfactory cues to locate mates and oviposition sites.

The scent of death: A case study for volatile markers of decomposition on a concrete floor

Journal of Forensic Sciences, EarlyView.
Abstract Volatile organic compounds (VOCs) released during human decomposition are chemically diverse and can provide forensic evidence indicating the prior presence of a corpse. In July 2023, the Michigan City Police Department received a report from an individual claiming to have murdered his roommate and stored the body in a basement cellar for 57 ...

Transcriptome Analysis of Gene Families Involved in Chemosensory Function in Spodoptera littoralis (Lepidoptera: Noctuidae)

BMC Genomics, 2019
Background Deciphering the molecular mechanisms mediating the chemical senses, taste, and smell has been of vital importance for understanding the nature of how insects interact with their chemical environment. Several gene families are implicated in the

Sensory cell proliferation within the olfactory epithelium of developing adult Manduca sexta (Lepidoptera). [PDF]

PLoS ONE, 2007
BACKGROUND:Insects detect a multitude of odors using a broad array of phenotypically distinct olfactory organs referred to as olfactory sensilla. Each sensillum contains one to several sensory neurons and at least three support cells; these cells arise ...

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

Insect Molecular Biology, EarlyView.
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

Gas Chromatography‐Based Methods for Profiling Volatile Off‐Aroma Compounds in Grain Legumes: A Review

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Instrumental characterisation of the volatile organic compounds (VOCs), responsible for off‐aroma, is mainly centred on gas chromatography‐based techniques. Despite previous reviews that have addressed the chemical compounds and biosynthetic pathways of off‐aroma generation, to date, there is a lack of a comprehensive review that critically ...

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

Flavour and Fragrance Journal, Volume 41, Issue 3, Page 487-503, May 2026.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.

Integrative Metabolomic and Transcriptomic Profiling Reveals the Chemical and Molecular Basis for Aroma Divergence in Isatis Fruits

Food Frontiers, Volume 7, Issue 3, May 2026.
Integrative metabolomic and transcriptomic analyses revealed the chemical and molecular basis of aroma divergence in fruits of three Isatis species. Distinct volatile profiles and 44 key aroma‐active compounds defined species‐specific sensory characteristics, while co‐expression analysis identified NAC transcription factors and lipid‐derived pathway ...

GOBP1 Plays a Key Role in Sex Pheromones and Plant Volatiles Recognition in Yellow Peach Moth, Conogethes punctiferalis (Lepidoptera: Crambidae)

Insects, 2019
Insects recognize odorous compounds using sensory neurons organized in olfactory sensilla. The process odor detection in insects requires an ensemble of proteins, including odorant binding proteins, olfactory receptors, and odor degrading enzymes; each ...
