Abstract
Corpora cardiaca (CC) of the migratory locust contain two antidiuretic (AD) factors increasing the fluid reabsorption of isolated recta over a 5-h period. They are contained in storage lobes (SL) and glandular lobes (GL) of the CC. They differ in size and can be separated from each other in different ways (extraction, dialysis, electrophoresis). The AD factor contained in GL of the CC is stable at 4°C and quickly destroyed at 100°C. It stimulates the fluid reabsorption in a dose-dependent manner. Its release into the haemolymph seems to be controlled by octopamine, which is probably synthesized in the lateral neurosecretory areas of the brain.Keywords
