This study identifies Drosophila busckii's tolerance and use of dimethyldisulfide (DMDS) as an olfactory cue for host selection, linking it to an insensitive cytochrome c oxidase.

The paper quantifies sex-specific compounds in 99 drosophilid species, showing significant variation in concentrations that may contribute to reproductive isolation.

The paper investigates whether sensitization occurs in different Drosophila olfactory sensory neuron types and identifies mitochondrial involvement in this process.

This study identifies male pheromones that shorten the ejaculate holding period in Drosophila females by activating pC1 neurons via cAMP, promoting re-mating.

This study shows that olfactory learning modulates second-order olfactory neurons in Drosophila, affecting innate odor-guided behavior through bidirectional plasticity.

The paper shows that a specific olfactory circuit in Drosophila melanogaster undergoes structural changes after exposure to geosmin, leading to behavioral adaptation.

The paper identifies tissue-specific and geographically variable olfactory receptor expression in the fig wasp Ceratosolen fusciceps, suggesting novel roles for ORs beyond the antennae.

The paper compares synaptic circuitry differences between broadly and narrowly tuned glomeruli in Drosophila to identify generic features of olfactory circuits.

The paper investigates the co-expression of gustatory receptor Gr64b with olfactory receptors in Drosophila OSNs and finds no functional role for Gr64b in odor detection.

This study identifies 208 odorants relevant to locust ecology and shows that locust olfactory receptors are narrowly tuned to specific ligands, with single receptor knockouts abolishing responses to their ligands.

This study examines how odor information is transformed and represented in higher-order neurons of the Drosophila lateral horn, finding that these neurons encode odor valence and identity through specific response patterns.

This study functionally characterizes odorant receptor orthologues in three conifer-feeding beetle species, finding conserved responses to ecologically relevant odors.

This study investigates how female hawkmoths distinguish between crucial and background plant odors, finding that their olfactory system uniquely codes for larval host plants even when these odors are subtle.

This study investigates the functional interaction between Drosophila olfactory sensory neurons and their support cells, revealing that support cells actively participate in odor processing.

This study identifies age-related changes in sensory gene expression in Rhodnius prolixus antennae, revealing three expression profiles of sensory-related genes across the first week post-ecdysis.

The paper characterizes sex pheromone communication systems in Drosophila by analyzing phylogenetic and chemical traits across 99 species, identifying 51 sex-specific compounds and their roles in reproductive isolation.

The paper identifies and characterizes two odorant receptors in bark beetles, predicting their ligand binding sites and highlighting key residues involved in pheromone recognition.

Alcohol exposure increases pheromone production in male flies, enhancing courtship success, but methanol is toxic, requiring a balance between benefits and risks.

The paper identifies two male-specific pheromones in Drosophila mojavensis subspecies and shows how they contribute to sexual isolation through conserved sensory pathways and differential interpretation.

The paper shows that inhibiting programmed cell death in Drosophila olfactory neurons generates functional 'undead' neurons that integrate into circuits and contribute to evolutionary differences in carbon dioxide sensing.

This study identifies molecular and neuronal changes underlying behavioural divergence in Drosophila sechellia through mutational analysis and calcium imaging.

The paper shows that the co-receptor IR8a is essential for hawkmoths to avoid ovipositing on plants already attacked by conspecific caterpillars, based on frass-emitted carboxylic acids.

This study uses CRISPR-Cas9 to knock out orco in hawkmoths, showing impaired foraging but normal oviposition behavior.

This paper introduces a silica hydrogel embedding method that preserves cell activity for functional studies of delicate tissues.
