评价了甲脒杀虫脒（CDF）、去甲脒CDF、BTS-27271（NOR-AM 49844）和双甲脒;拟除虫菊酯-氯氟氰菊酯;以及氨基甲酸酯硫双威的杀卵活性和对烟芽夜蛾（Heliothis virescens（F.））卵中章鱼胺滴度的影响。CDF和三氟氯氰菊酯是毒性最强的化合物，其次是去甲基CDF和BTS-27271。虽然在未处理的H. virescens，三种甲脒导致处理的鸡蛋中出现章鱼胺。氯氟氰菊酯、双甲脒和硫双威对章鱼胺滴度没有明显影响。放射性双甲脒在血吸虫卵中的体内代谢研究。virescens表明BTS-27271可能是代谢产物。由于章鱼胺参与昆虫行为和能量动员，因此甲脒诱导的章鱼胺滴度改变可能会改变关键孵化过程中的行为反应或能量可用性，导致死亡率增加。
The formamidines chlordimeform (CDF), desmethyl-CDF, BTS-27271 (NOR-AM 49844) and amitraz; the pyrethroid lambda-cyhalothrin ; and the carbamate thiodicarb were evaluated for ovicidal activity and effects on octopamine titers in eggs of the tobacco budworm, Heliothis virescens (F.). CDF and lambda-cyhalothrin were the most toxic of the compounds examined, followed by desmethyl-CDF and BTS-27271. Although octopamine is not detectable in untreated eggs of H. virescens , three formamidines caused the appearance of octopamine in treated eggs. lambda-cyhalothrin , amitraz, and thiodicarb had no apparent effect on octopamine titers. In vivo metabolism studies of radiolabeled amitraz by eggs of H. virescens indicate that BTS-27271 is a likely metabolite. Because octopamine is involved in insect behavior and energy mobilization, the formamidine-induced alteration of octopamine titers might alter behavioral responses or energy availability during the critical hatching process leading to increased mortality.
