中文摘要：

测定亚致死剂量昆虫生长调节剂双氧威和虫酰肼对亚洲玉米螟5龄幼虫发育历期、化蛹率、体重、脂质含量及血清中糖和蛋白含量的影响。结果表明：双氧威LC30、LC20、LC10依次为22．23、14．75、4．37μg／mL，虫酰肼LC30、LC20、LC10依次为48．20、37．11、21．73μg／mL。LC30亚致死剂量双氧威处理可使5龄幼虫的发育历期延长至8．33±0．69天，而虫酰肼处理则使其缩短至5．49±0．66天。亚致死剂量双氧威和虫酰肼处理均使幼虫体重及化蛹率明显降低（P〈0．01），其体内脂质含量和血清中糖和蛋白含量也低于对照组（P〈0．01），同时5龄幼虫血清中储存蛋白的合成受到抑制。

英文摘要：

Developmental time, pupation rate, body weight, the contents of lipid and carbohydrate contents in hemolymph of 5th instar larvae of Ostrinia furnacalis Guenée treated with sublethal concentration of fenoxycarb and tebufenozide were determined. The LC30, LC20 and LC10 of fenoxycarb were 22. 23, 14.75 and 4.37 μg/mL, and those of tebufenozide were 48.20, 37. ll and 21.73 μg/mL, respectively. The developmental time of 5^th instar larvae of O. furnacalis treated with LC30 sublethal concentration of fenoxycarb extended to 8.33 ± 0.69 days. For treatment with LC30 sublethal concentration of tebufenozide, however, the developmental time shortened to 5.49 ±0.66 days. Body weight and pupation rate of 5^th instar larvae of O. furnacalis treated with LC30 sublethal concentration of fenoxycarb and tebufenozide decreased significantly（P 〈0.01）, and the contents of lipid, protein and carbohydrate in hemolymph were lower than those of control group（P 〈 0.01 ）. Meanwhile, the synthesis of storage protein in hemolymph was inhibited.
