摘　　要：为提高生物药剂使用效率,减少化学农药使用量,将50000 IU/mg Bt-G033A WP分别与30%灭蝇胺SC、25%灭幼脲SC和20%虫酰肼SC减量联合应用。共毒因子法初步筛选结果表明,Bt-G033A:灭蝇胺75:25、Bt-G033A:灭幼脲25:75和50:50的配比处理均表现为增效作用,Bt-G033A:灭蝇胺25:75和50:50、Bt-G033A:虫酰肼75:25、Bt-G033A:灭幼脲75:25处理均表现为相加作用。共毒系数法筛选结果表明,Bt-G033A与灭蝇胺平均共毒系数83.75,表现为相加作用;Bt-G033A与灭幼脲复配共毒系数为131.76,表现为增效作用,其中50:50增效最明显,增效系数最大为203.25。最佳复配剂Bt-G033A:灭幼脲50:50田间试验结果表明,药后3~21 d对番茄潜叶蛾防治效果64.76%~89.12%,均可高于灭幼脲和Bt-G033A单剂防效。In order to improve the efficiency of the use of biological agents and reduce the use of chemical pesticides,50000 IU/mg Bt-G033A(WP)was combined with 30%cyromazine SC,25%chlorbenzuron SC and 20%tebufenozide SC to control Tuta absoluta Meyrick,respectively.The treatments of Bt-G033A:cyromazine 75:25,Bt-G033A:chlorbenzuron 25:75 and 50:50 showed synergistic control effects on T.absoluta Meyrick,and the treatments of Bt-G033A:cyromazine 25:75 and 50:50,Bt-G033A:tebufenozide 75:25,Bt-G033A:chlorbenzuron 75:25 showed additive control effects on T.absoluta Meyrick by co-toxicity factor method,respectively.The co-toxicity coefficient of Bt-G033A combined with cyromazine against T.absoluta Meyrick was 83.75 showing additive effect,and the co-toxicity coefficient of Bt-G033A combined chlorbenzuron against T.absoluta Meyrick was 131.76 showing synergistic effect.The field trials showed that control effect of Bt-G033A:chlorbenzuron 50:50 agent was 64.76%~89.12%in 3~21 d,which was significantly higher than that of chlorbenzuron and Bt-G033A single agent.
