| 摘 要： | 研究了三唑磷、杀虫双、阿维菌素和Bt+吡虫啉4种药剂处理对安徽江淮地区早稻田害虫 天敌群落的影响.结果表明，4种药剂处理对主要害虫的种群增长均有显著控制作用.三唑磷对群落多样性影响最大，其次是杀虫双和阿维菌素，其各处理区群落多样性平均值分别为1.545、1.562和1.691，均显著低于空白对照区（群落多样性平均值为1.897）；Bt+吡虫啉处理区群落多样性平均值为1.915，较空白对照区有所提高.药剂处理2周后，杀虫双处理区与阿维菌素处理区的群落组成最相似，三唑磷处理区与Bt+吡虫啉处理区最不相似.从群落稳定性和害虫可持续控制的角度看，4种药剂处理中以Bt+吡虫啉最优，而杀虫双和阿维菌素又稍优于三唑磷.

| Abstract: | This paper studied the effects of triazophos,shachongshuang,abamectin,and Bt + imidacloprid on the insect pest-natural enemy community in early rice fields in the Yangtze-Huaihe region of Anhui Province.The results showed that all of the test insecticides had significant effects in controlling the growth of major insect pest populations.The average value of insect pest-natural enemy community diversity under effects of triazophos,shachongshuang,abamectin,and Bt+imidacloprid was 1.545,1.562,1.691 and 1.915,respectively,while that in control plot was 1.897.After two weeks of applying insecticides,the plots applied with shachongshuang and abamectin had a similar composition of insect pest-natural enemy community,but the community composition was significantly different between the plots applied with triazophos and Bt + imidacloprid.From the viewpoints of community stability and pest control,Bt + imidacloprid had the best effect,and shachongshuang and abamectin were better than triazophos. |
