摘　　要：选取氟啶脲(Chlorfluazuron)和灭幼宝(Pyriproxyfen)两种昆虫生长调节剂对储藏物害虫赤拟谷盗进行了控制效果的研究。结果表明,在402、0、10 mg/kg剂量下,氟啶脲对赤拟谷盗幼虫有较高的校正死亡率,依次为94.44%8、8.89%、83.33%,幼虫均不能化蛹,表明该药剂可能作用于几丁质合成酶,抑制了几丁质合成酶的活性。在相同浓度下,灭幼宝对赤拟谷盗幼虫没有明显的致死效果,但其能延长赤拟谷盗幼虫的发育历期,使其不能正常化蛹,最终导致畸形死亡,表明灭幼宝有类似保幼激素的作用。The paper study the control effectiveness of two IGRs, Chlorfluazuron and Pyriproxyfen to Tribolium castaneum, a main insect pest occurring in stored product. The result showed that Chlorfluazuron had a high mortality rate on Tribolium castaneum larva, which is 94.44% ,88.89% ,83.33 % corresponding to the concentration of 40,20, 10 mg/kg. , and make them pupate hardly, so Chlorfluazuron had significant death effect on Tribolium castaneum lar- va, and it acted on chitin synthase, inhibiting the activity of chitin synthase. Pyriproxyfen didn＇t have obvious death effect on Tribolium castaneum at the same concentration as Chlorfluazuron, but Pyriproxyfen can delay the development of Tribolium castaneum larva, affect their normal pupa, and eventually cause their deformity death. The result preliminary shows that Pyriproxyfen has similar function as juvenile hormones.
