Several synthetic juvenile hormones were applied topically and by injection to adult male Blattella germanica. These compounds included the Law synthetic juvenile hormone, the synthetic Roeller compound and farnesyl O-methyl ether. Mortalities were low upon topical application but much higher upon injection into the abdomen. Twenty-four hours after treatment the surviving males were confined with mature virgin females to test for their ability to mate and transfer sperm successfully. Control males were treated in similar fashion but only with the carrier solvent. This series of experiments did not provide any evidence that the hormone mimics resulted in any failure to inseminate. Viable young were produced in quantities approximating those of control sets. Treated male cockroaches were dissected and compared with control animals. No effectable differences were apparent in the degree of development of the reproductive organs.
