Effects of a Synthetic Juvenile Hormone Mimic on the Reproduction of the Tsetse Fly Glossina Morsitans

Abstract

Topical application of the juvenile hormone mimic I-75 to pregnant Glossina morsitans 15 or 20 days after emergence resulted in a significant increase in abortions of eggs and larvae of all developmental stages. Small doses (0.25 ng per fly) were sufficient to elicit a response which was more pronounced if application occurred 20 days after emergence. Flies fed once on rabbit ears, which had been treated with 5 ng of the mimic per ear, resulted in abortions and the effect persisted for up to 40 days. The hormone mimic did not induce abortions in isolated pregnant uteri kept in organ cultures for up to 7 days.
