摘要： 通过室内试验，研究了10种菊酯类农药对水稻二化螟幼虫的生物活性，以及高效氯氟氰菊酯5种剂型对二化螟幼虫的生物活性差异。结果表明：高效氟氯氰菊酯、高效氯氟氰菊酯、S-氰戊菊酯、溴氰菊酯、甲氰菊酯、顺式氯氰菊酯、高效氯氰菊酯、乙氰菊酯、醚菊酯、氟硅菊酯对水稻二化螟幼虫均有较高的活性，LD50（μg /头）分别为0.0017，0.0039，0.0043，0.0070，0.0071，0.0116，0.0119，0.714，0.1779，0.3858，其活性分别是对照药剂三唑磷的0.3-141.59倍，是甲胺磷的2.07- 469.06倍。高效氯氟氰菊酯5剂型对二化螟3龄幼虫的生物活性略有差异，LC50(mg/L)值分别为：0.0945（EW），0.1089（EC），0.1174(ME)，0.1232(SC)，0.1591(WP)。

Abstract: This paper investigated the bioactivity of 10 pyrethroid insecticides to striped rice borer Chilo suppressalis (walker) in the lab. The results showed that the LD50 (μg/larva) of beta-cyfluthrin, lambda-cyhalothrin, esfenvalerate, deltamethrin, fenpropathrin, alpha-cypermethrin, beta-cypermethrin, cycloprothrin, etofenprox, and silafluofen to C. suppressalis are 0.0017, 0.0039, 0.0043, 0.0070, 0.0071, 0.0116, 0.0119, 0.714, 0.1779, 0.3858, respectively. Bioactivity of 5 formulations of lambda-cyhalothrin to C. suppressalis (walker) are different. The LC50 (mg/L) of EW, EC, ME, SC and WP formulations of lambda-cyhalothrin to C. suppressalis (walker) are 0.0945, 0.1089, 0.1174, 0.1232, 0.1591, respectively.
