• Aminopterin at a 50 μg dosage had no effect on the fertility of the male silkworm when injected in the fifth larval instar, but fertility decreased markedly when it was injected at the period from the start of spining to the begining of the pupal stage. However, when injected at the latter half of the pupal stage the fertility increased again. Spermatogenic cells in the testes treated at the most sensitive stage exhibited no visible abnormality following the treatment and developed normally. At emergence, spermatozoa safely penetrated into the vas efferens, but the number in the ampulla ductus deferentis of the treated male was considerably reduced and either no spermatozoa or very few, if any, were found in the reproductive organs of the untreated female mated with the sterilized male.
