摘　　要：目的研究植物提取物对德国小蠊种群数量的影响,为开发和应用植物杀虫剂提供依据。方法将植物提取物配制成药饵,饲喂德国小蠊,观察其死亡及孵化等情况。结果在供试的18种植物样品中,有10种植物的提取物对德国小蠊的繁殖具有明显的抑制作用。其中以种植样品Ps-1和Ps-25的提取物饲喂德国小蠊时,卵荚死亡率分别为28.95%和76.95%,每只卵荚孵化的平均若虫数分别为15.22只和12.56只,效果最为显著。结论植物样品Ps-1和Ps-25的次生物质能有效抑制德国小蠊种群数量的增长,具有开发利用价值。Objective To test the inhibition effects of plant extracts on Blattella germanica,and develop green botanical insecticides. Methods Extracts were mixed in the cockroach fodder,then feed the cockroaches. Results 10 of all 18 plant samples could restrain Blattella germanica breeding. The effects of Ps- 1 and Ps- 25 were the best,respectively causing 28. 95% and 76. 95% morality of egg-pod. The average hatched eggs were 15. 22 and 12. 56 per egg-pod when treated with the extracts of Ps- 1 and Ps- 25. Conclusion The extracts of Ps- 1 or Ps- 25 plant sample can restrain Blattella germanica.
