These investigations extended the study of apholate chemosterilization to Hymenoptera and used the response of Bracon hebetor Say ovarioles to interpret effects in terms of the variety of cell types present in an insect ovary. Three modes of application to adult females were compared: topical, contact with a coated surface, and injection. No reduction in life span occurred, but egg production and hatchability were drastically reduced. Injection was most effective for decreasing fecundity and fertility. Contact application was least effective. Cystocytes in the process of differentiation were the most sensitive of cell types. Second in sensitivity were the undifferentiated oƶgonia destined to undergo differentiation. Mitosis and endomitosis, the nuclear processes involved in successful differentiation of ovariole contents, are both vulnerable to DNA alkylation.
