Preference for and resistance to a toxic sulfur volatile opens up a unique niche in Drosophila busckii

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.

Temperature-mediated dynamics: unraveling the impact of temperature on cuticular hydrocarbon profiles, mating behavior, and life history traits in three Drosophila species

Temperature-dependent modulation of odor-dependent behavior in three drosophilid fly species of differing thermal preference

This study examines how temperature affects odor-guided behavior in three drosophilid flies with different thermal preferences.

Aversive bimodal associations impact visual and olfactory memory performance in Drosophila

This study shows that bimodal sensory integration in Drosophila affects visual and olfactory memory differently, with visual memory improving but olfactory memory being suppressed or only slightly enhanced.

Increased ozone levels disrupt insect sexual communication

This study shows that increased ozone levels oxidize male-specific pheromones in Drosophila melanogaster, reducing pheromone amounts and altering sexual recognition.

Comparative dissection of the peripheral olfactory system of the Chagas disease vectors Rhodnius prolixus and Rhodnius brethesi

This study compares the olfactory systems of two closely related triatomine species, Rhodnius prolixus and Rhodnius brethesi, revealing functional differences in their responses to host and habitat volatiles.

Evolution of a pest: towards the complete neuroethology of Drosophila suzukii and the subgenus Sophophora

The paper assesses olfactory functions in Drosophila suzukii and related species to identify evolutionary patterns in chemosensory receptors.

Niche partitioning as a selective pressure for the evolution of the Drosophila nervous system

This study investigates a tradeoff between visual and olfactory investment in two closely related Drosophila species, suggesting that niche partitioning through sensory specialization facilitates coexistence.

Optimization of insect odorant receptor trafficking and functional expression via transient transfection in HEK293 cells

This study improves the functional expression of insect odorant receptors in HEK293 cells by optimizing trafficking signals and using a bidirectional expression vector.

Learning may help pollinators find their host plants in polluted landscapes

This study shows that pollinators can learn to find host plants despite ozone pollution altering floral scents, by associating altered odors with rewards.

Transcriptome Surveys in Silverfish Suggest a Multistep Origin of the Insect Odorant Receptor Gene Family

The paper identifies multiple odorant receptor (Or) gene family members in silverfish and proposes they represent an evolutionary intermediate between gustatory receptors and higher insect Ors.

The Drosophila pheromone Z4-11Al is encoded together with habitat olfactory cues and mediates species-specific communication
