This review focuses on neuropeptides and peptide hormones, the largest and most diverse
class of neuroactive substances, known in Drosophila and other animals to play roles in …

Sexual dimorphism is common throughout the animal kingdom. However, a molecular
understanding of how sex-specific traits develop and evolve has been elusive. Recently …

Doublesex proteins, which are part of the structurally and functionally conserved Dmrt gene
family, are important for sex determination throughout the animal kingdom. We inserted Gal4 …

Many animals rely on vision to detect, locate, and track moving objects. In Drosophila
courtship, males primarily use visual cues to orient toward and follow females and to select …

Background Sex-specific behavior may originate from differences in brain structure or
function. In Drosophila, the action of the male-specific isoform of fruitless in about 2000 …

Insects exhibit a variety of sex determining mechanisms including male or female
heterogamety and haplodiploidy. The primary signal that starts sex determination is …

Background The social life of animals depends on communication between individuals.
Recent studies in Drosophila melanogaster demonstrate that various behaviors are …

Sex determination refers to the developmental programme that commits the embryo to either
the male or the female pathway. The animal kingdom possesses a wealth of mechanisms …

The Drosophila melanogaster sex hierarchy controls sexual differentiation of somatic cells
via the activities of the terminal genes in the hierarchy, doublesex (dsx) and fruitless (fru) …

The Drosophila sex pheromone cVA elicits different behaviors in males and females. First-
and second-order olfactory neurons show identical pheromone responses, suggesting that …
