Two members of a widely studied family of chemoreceptors, the "orphan" chemoreceptor IR21a and its putative co-receptor IR25a, act together to mediate cool sensation in fruit fly larvae.
The neurons and receptors mediating moist air detection in Drosophila are identified, revealing that moist and dry air detection depend on overlapping Ionotropic Receptors and that these pathways are both critical for hygrosensation.
A combination of genetics, behavior and physiology demonstrate that cool and moisture sensing rely on overlapping combinations of sensory receptors in Drosophila.
Optogenetics and reverse-correlation have decoded the computations by which the Drosophila larva makes navigational decisions on the basis of time-varying sensory neuron activity.
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.
Visualized odor encounters show that Drosophila navigate spatiotemporally complex odor plumes using random walks biased by the timing of brief and unpredictable odor encounters.
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.
