A genetic analysis reveals that some olfactory sensilla of Drosophila do not require an abundant odorant binding protein and that one such protein may act in gain control.
A moth can detect plant volatiles using an odorant receptor expressing in its ovipositor, and this odorant receptor has a much higher expression level in the ovipositor than antennae.
Although odorant binding proteins are widely believed to be required for transport of odorants to receptors, six types of sensilla of Drosophila respond robustly in their absence to many odor stimuli.
Hygroreception, a poorly understood process critical to insect survival, depends on a small protein in the antenna of the fruit fly that was previously thought to transport odorants.
The evolutionary transition of the agricultural pest Drosophila suzukii to egg laying on ripe fruits was paralleled with several gustatory innovations.
Two different classes of taste receptor neurons in the Drosophila melanogaster proboscis play distinct roles in yeast feeding and are both modulated by the fly's internal amino acid state in order to promote protein-specific appetite.
The gustatory receptor PxylGr34 is tuned to the steroid plant hormone brassinolide and mediates the deterrent effects of brassinolide on feeding and ovipositing behaviors in Plutella xylostella.
Molecular-genetic, neural imaging and behavioral analyses reveal how Drosophila melanogaster sense fatty acids, important nutrient compounds, through multimeric Ionoptropic Receptors complexes.
Differing from its ortholog in Helicoverpa armigera, pheromone receptor HassOr14b is tuned to the major sex pheromone component in H. assulta, and two amino acids in the intracellular domain determine their ligand selectivity.
