摘  要：
为了探讨一些高效、低毒杀虫剂品种对灰同缘小叶蝉的影响和适用性,采用生化分析方法,测定了3种杀虫剂的毒力及对灰同缘小叶蝉体内保护酶和解毒酶活性的影响。结果表明,不同杀虫剂对灰同缘小叶蝉的毒力差异明显,其中阿维菌素的毒力最高。经阿维菌素、吡虫啉和噻嗪酮-异丙威处理后,灰同缘小叶蝉体内的过氧化氢酶(CAT)、过氧化物酶(POD)和超氧化物歧化酶(SOD)的活性在多数时间段均得到增强,其中吡虫啉的作用变化较平稳。解毒酶的活性表现出不同的变化趋向,阿维菌素和吡虫啉对灰同缘小叶蝉体内的羧酸酯酶(Car E)和谷胱甘肽S-转移酶(GST)活性有一定的促进作用,而噻嗪酮-异丙威的作用则变化较大,表现为在作用时间内Car E完全受到抑制,而GST的活力在作用前期、中期得到增强。

摘  要：
In order to expore the effects and applicability of insecticides with efficient and low toxicity on Coloana cinerea,the biochemical analysis method was used to test the toxicities and effects of three insecticides on protective enzyme and detoxification enzyme activities in C. cinerea. The results showed that different insecticides had significantly different toxicities on C. cinerea,and abamectin had the highest toxicity. Treated by three insecticides,the catalase(CAT),peroxidase(POD)and superoxide dismutase(SOD)activities in C. cinerea enhanced generally,the effect of imidacloprid was relatively stable. Abamectin and imidacloprid had some promotion to the carboxylesterase(Car E)and glutathione S- transferase(GST)activities of C. cinerea. The Car E activity of C. cinerea was inhibited significantly after treated by isoprocarb-buprofezin from 1 h to 15 h,while the GST activity of C. cinerea enhanced from 1 h to 10 h.
