The evolution of animal behaviour is poorly understood 1 , 2 . Despite numerous correlations
between interspecific divergence in behaviour and nervous system structure and function, …

Divergent populations across different environments are exposed to critical sensory information
related to locating a host or mate, as well as avoiding predators and pathogens. These …

Insects use sex pheromones as a reproductive isolating mechanism to attract conspecifics
and repel heterospecifics. Despite the profound knowledge of sex pheromones, little is known …

In insects, like in other animals, experience‐based modulation of preference, a form of
phenotypic plasticity, is common in heterogeneous environments. However, the role of multiple …

Pathogens and parasites can manipulate their hosts to optimize their own fitness. For
instance, bacterial pathogens have been shown to affect their host plants’ volatile and non-volatile …

Communication mechanisms underlying the sexual isolation of species are poorly understood.
Using four subspecies of Drosophila mojavensis as a model, we identify two behaviorally …

In Drosophila melanogaster, the sex pheromone produced by males, cis-vaccenyl acetate (cVA),
evokes a stereotypic gender-specific behavior in both males and females. As …

10.7554/eLife.14925.001 The vinegar fly Drosophila melanogaster is equipped with two
peripheral olfactory organs, antenna and maxillary palp. The antenna is involved in finding food, …

Dietary composition affects food preference in animals. High sugar intake suppresses sweet
sensation from insects to humans, but the molecular basis of this suppression is largely …

Programmed cell death (PCD) is widespread during neurodevelopment, eliminating the
surpluses of neuronal production. Using the Drosophila olfactory system, we examined the …
