Objective To research the serial toxic effects of 0.05% fipronil cockroach gel bait on adults and nymphs of Blattella germanica. Methods This experiment used pipette to offer insecticide in the first efficacy experiment; and the serial toxic effect experiment was conducted using the dead insect of last serial toxic effect experiment to feed the cockroach. Results The first to fourth secondary effects of tested insecticide on adults reached 100%, the fifth secondary effects from the remains amounted to 78.3%. Against nymphs, however, only the first two secondary effects reached 100%, the third and fourth mortality were only 48.3% and 15.0%. The results indicated that 0.05% fipronil cockroach gel bait can continuously controlB. germanica effectively and it was more effectively on adults than on nymphs. Conclusion Fipronil has a good serial toxic effect on B. germanica.

目的 研究0.05%氟虫腈杀蟑胶饵对德国小蠊成虫和若虫的继发传递毒性。方法 首次毒杀实验采用移液枪头内腔放置给药的方式;继发毒杀实验均使用上次毒杀实验虫尸饲喂的方式进行。结果 0.05%氟虫腈杀蟑胶饵对德国小蠊成虫前4次继发毒杀的死亡率均可达100%,第5次继发毒杀的死亡率最高达78.3%;而对若虫仅进行2次毒杀的死亡率可达100%,第3次和第4次继发毒杀的死亡率分别为48.3%和15.0%,对成虫的继发毒杀效果明显优于若虫。结论 0.05%氟虫腈对德国小蠊具有良好的多次继发传递毒性。
