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 …

Immune defense and reproduction are physiologically and energetically demanding
processes and have been observed to trade off in a diversity of female insects. Increased …

Seminal fluid proteins (SFPs) produced in reproductive tract tissues of male insects and
transferred to females during mating induce numerous physiological and behavioral …

Life history theory seeks to explain the evolution of the major features of life cycles by
analyzing the ecological factors that shape age-specific schedules of growth, reproduction …

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 …

The gastrointestinal tract is emerging as a key regulator of appetite and metabolism, but
daunting neuroanatomical complexity has hampered identification of the relevant signals …

The production of offspring is energetically costly and relies on incompletely understood
mechanisms that generate a positive energy balance. In mothers of many species, changes …

Plasticity in animal behaviour relies on the ability to integrate external and internal cues from
the changing environment and hence modulate activity in synaptic circuits of the brain. This …

Disruptions in energy homeostasis severely affect reproduction in many organisms and are
linked to several reproductive disorders in humans. As a result, understanding the …

Measurement of food intake in the fruit fly Drosophila melanogaster is often necessary for
studies of behaviour, nutrition and drug administration. There is no reliable and agreed …
