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 …

Secretions of male accessory glands contain a variety of bioactive molecules. When
transferred during mating, these molecules exert wide-ranging effects on female …

A growing body of evidence has begun to reveal flaws in the traditional assumption of
female passivity and lack of discrimination after copulation has begun. William Eberhard has …

One hundred years after Darwin considered how sexual selection shapes the behavioral
and morphological characteristics of males for acquiring mates, Parker realized that sexual …

FEMALE Drosophila melanogaster with environmentally1–3 or genetically4 elevated rates
of mating die younger than controls. This cost of mating is not attributable to receipt of …

Studies of neuropeptide and peptide hormone signaling are coming of age in Drosophila
due to rapid developments in molecular genetics approaches that overcome the difficulties …

Courtship in Drosophila is influenced by a wide variety of genes, in that many different kinds
of pleiotropic mutations lead to defective courtship. This may seem to be a truism, but the …

Although sexual selection can provide benefits to both sexes, it also can be costly because
of expanded opportunities for intersexual conflict. We evaluated the role of sexual selection …

▪ Abstract Courtship is a complex behavior in Drosophila that recruits a wide range of genes
for its realization, including those concerning sex determination, ion channels, and circadian …

Mating elicits two major changes in the reproductive behavior of many insect females. The
egg-laying rate increases and the readiness to accept males (receptivity) is reduced. These …
