Recent Developments in Insect Neurohormones

The most striking fact revealed by investigations of insect neurohormones is that insects are as well supplied with neurohormones as mammals, since neurohor­ mones regulate not only the functioning of the endocrine glands, prothoracic gland, and corpora allata, but also most physiological processes. Our knowledge of neurohormones developed originally from anat­ omocytological investigations and experimental studies. Today, accurate bio­ assays have been devised for studying both in vivo and...
