Abstract: | This paper reviews the evidence for a possible endocrine basis for the remarkable synchrony often observed between the development of entomophilic nematodes and that of their hosts. Although some suggestive observations have been made by various workers, there is no rigorous evidence which points to such an association. In those few cases which have been rigorously examined, there is some evidence that the synchrony is not based upon endocrine signals passing between host and parasite. The possibility that the parasite may manipulate the endocrinology of the insect in order to alter the metabolism and physiology of the host to favour the parasite has received less attention, but is nevertheless thought to constitute a promising areas of research. |
