Darwin's theory of sexual selection fundamentally changed how we think about sex and
evolution. The struggle over mating and fertilization is a powerful driver of diversification …

The majority of insect olfactory receptors belong to two distinct protein families, the
ionotropic receptors (IRs), which are related to the ionotropic glutamate receptor family, and …

The sense of smell enables insects to recognize and discriminate a broad range of volatile
chemicals in their environment originating from prey, host plants and conspecifics. These …

There is growing interest in using Drosophila melanogaster to elucidate mechanisms that
underlie the complex relationships between a host and its microbiota. In addition to the …

The identification of active neurons and circuits in vivo is a fundamental challenge in
understanding the neural basis of behavior. Genetically encoded calcium (Ca2+) indicators …

Abstract Ionotropic Receptors (IRs) are a recently characterized family of olfactory receptors
in the fruit fly, Drosophila melanogaster. IRs are not related to insect Odorant Receptors …

In nature, the fruit fly D rosophila melanogaster is attracted to fermenting fruit. Micro‐
organisms like S accharomyces yeasts growing on fruit occupy a commonly overlooked …

Chemoreception is essential for survival. Feeding, mating, and avoidance of predators
depend on detection of sensory cues. Drosophila contains diverse families of …

Although eusociality evolved independently within several orders of insects, research into
the molecular underpinnings of the transition towards social complexity has been confined …

The ability to find and consume nutrient-rich diets for successful reproduction and survival is
fundamental to animal life. Among the nutrients important for all animals are polyamines, a …
