ResumoLangley (1967) showed that laboratory-reared tsetse flies, Glossina morsitans Westwood, (reared from fieldcaught pupae) excrete more slowly after feeding, secrete proteases more slowly after feeding, and are less willing to feed again, several days after feeding, than wild-caught adult flies. In general, digestive activity in laboratory reared flies is slower than in field-captured flies. Langley attributed this difference to a lessening of neuro secretory activity in the laboratory-reared flies, although this lessening is toi) slight to be detected histologically. Neurosecretions of the brain-corpora cardiaca have been shown to be important in the regulation of proteolytic enzymes (Wigglesworth 1964, Novak 1966).
