Dopamine (DA) and serotonin (5HT) are reported to serve important roles in aggression in a
wide variety of animals. Previous investigations of 5HT function in adult Drosophila behavior …

To study the function of the neuropeptide pigment-dispersing factor (PDF) in the circadian
system of Drosophila, we misexpressed the pdf gene from the grasshopper Romalea in the …

Antibodies made against serotonin (5HT) were used to identify the serotonin neuronal
system in the developing and adult nervous system of Drosophila melanogaster. The 5HT …

The excretory system of insects comprises the Malpighian tubules and hindgut (ileum and

Rhodnius prolixus is an obligatory blood-feeder that can ingest blood meals of up to 10
times its mass. Rapid production of urine commences within 2–3 min of the start of feeding in …

Metabolic homeostasis and water balance is maintained by tight hormonal and neuronal
regulation. In Drosophila, insulin‐like peptides (DILPs) are key regulators of metabolism …

The concentration of serotonin in the haemolymph of fifth-instar larvae of Rhodnius prolixus
increase quickly after the onset of feeding. In insects fed on either blood or artificial diet the …

The insect ventral nerve cord consists of metamerically repeated ganglia subserving the
thoracic and abdominal segments. The abdominal ganglia control basic functions such as …
