摘要
[目的]了解农药对东亚小花蝽生长的影响.[方法]采用浸渍法,用5种常用农药分别处理东亚小花蝽卵.[结果]2%苦参碱水剂、430 g/L戊唑醇悬浮剂和30%噁霉灵水剂处理后的东亚小花蝽的卵,可以正常孵化、生长;10%虫螨腈悬浮剂处理后的东亚小花蝽的卵,虽然可以正常孵化,但孵化后48h若虫存活率显著降低(P＜0.05);20%呋虫胺可溶粒剂处理后的东亚小花蝽的卵,孵化率显著低于空白对照和其他处理(P＜0.05),卵孵化后48h若虫存活率也显著降低(P＜0.05).[结论]田间释放东亚小花蝽期间,要严格控制虫螨腈和呋虫胺的喷施,以免对其生长造成影响.
Abstract
[Objective]To understand the effect of pesticides on the growth of Orius sauteri.[Method]The eggs of Orius sauteri were treated with five common pesticides by impregnation method.[Result]The eggs of the Orius sauteri,which were treated with 2%matrine aqueous solu-tion,430 g/L tebuconazole suspension concentrate and 30%hymexazol aqueous solution respectively,could hatch and grow normally.Al-though the eggs of the Orius sauteri treated with 10%chlorfenapyr suspension concentrate could hatch normally,the nymph survival rate signif-icantly decreased within their eggs hatching 48 hours(P＜0.05).The hatching rate of the eggs of the Orius sauteri treated with 20%dinotefuran water soluble graule was significantly lower than that of the blank control group and other treatment groups(P＜0.05),and the nymph survival rate was also significantly decreased within their eggs hatching 48 hours(P＜0.05).[Conclusion]During the release of the Orius sauteri in the field,it is necessary to strictly control the spraying of chlorfenapyr and dinotefuran to avoid affecting their growth.
