Extract

Increased doses of tepa applied by injection to female Diparopsis castanea Hmps. caused a progressive increase in sterility accompanied by a decrease in the number of eggs oviposited from the time of application. After an interval of three days it was shown by histological examination that injected doses of 10 μg of tepa induced degeneration of the developing oocytes and a shrinkage or resorption of some of the mature eggs. After Diparopsis male moths were treated with graduated injected doses of apholate, metepa and tepa and then mated with untreated females, considerable embryonic development without subsequent egg hatch occurred at the lower dosage levels. When tepa-treated Autographa gamma (L.) males at a dose of 10 μg were similarly mated with untreated females histological examination showed that the development of many of the eggs had been arrested at a very early stage; in some instances a greater development, although of an abnormal kind, had taken place.
