摘　　要：为促进番茄病害绿色防控,筛选出对番茄潜叶蛾幼虫和成虫防治效果均较好的生物药剂,以保护地番茄潜叶蛾幼虫和成虫作为研究材料,通过喷雾法对金龟子绿僵菌可湿性粉剂、球孢白僵菌可湿性粉剂、苏云金杆菌可湿性粉剂、短稳杆菌乳油、0.3%印楝素乳油等5种生物药剂进行田间防治效果评价试验。结果表明:球孢白僵菌可湿性粉剂和苏云金杆菌可湿性粉剂对番茄潜叶蛾的幼虫和成虫均具有较好的防治效果,且防效逐渐增加,在药后15 d最好。幼虫防治效果显示,球孢白僵菌处理和苏云金杆菌处理药后3 d校正防效分别为27.85%和24.81%;药后7 d校正防效分别为63.95%和43.62%,且球孢白僵菌处理显著高于苏云金杆菌处理;药后15 d校正防效分别为82.59%和84.95%;2者在药后3、15 d均显著优于其他处理。成虫防治效果显示,球孢白僵菌处理和苏云金杆菌处理药后3 d成虫防效分别为62.41%和51.68%,且球孢白僵菌处理显著高于苏云金杆菌处理;药后7 d成虫防效分别为74.66%和76.94%;药后15 d成虫防效分别为80.08%和79.80%;2者始终均显著优于其他处理。因此,在实际生产中推荐每667 m^(2)施用球孢白僵菌可湿性粉剂200 g(500倍液)或苏云金杆菌可湿性粉剂200 g(500倍液)防治番茄潜叶蛾,且在发生高峰期前施用可达到较好的防治效果。In order to promote the green prevention and control of tomato diseases,and screen out biological fungicides for good control effects on larvae and adults of Tuta absoluta,the larvae and adults of T.absoluta were used as research materials,the field control effects of five biological fungicides of Metarhizium aeruginosa wettable powder(WP),Beauveria bassiana WP,Bacillus thuringiensis WP,B.brevis emulsifiable concentrate(EC)and 0.3%azadirachtin EC were evaluated by spray method.The results showed that B.bassiana WP and B.thuringiensis WP had good control effects on larvae and adults of T.absoluta whose control effect gradually increased,and the best control effect was the treatment of 15 days after spraying.The larval control effect 3 days after spraying fungicide showed that the corrected control effects under B.bassiana treatment and B.thuringiensis treatment were 27.85%and 24.81%,respectively.The corrected control effects 7 days after spraying fungicide under B.bassiana treatment and B.thuringiensis treatment were 63.95%and 43.62%,respectively,and the treatment of B.bassiana was significantly higher than that of B.thuringiensis treatment.The corrected control effects 15 days after spraying B.thuringiensis and B.thuringiensis were 82.59%and 84.95%,respectively.Both treatments above-mentioned were significantly better than other treatments of 3 days and 15 days after spraying,respectively.The adults control effect showed that the control effects of adults 3 days after spraying B.bassiana and B.thuringiensis were 62.41%and 51.68%,respectively,and the B.bassiana treatment was significantly higher than that of B.thuringiensis treatment.The control effects of adults 7 days after spraying B.bassiana and B.thuringiensis were 74.66%and 76.94%,respectively.The control effects of adults 15 days after spraying B.bassiana and B.thuringiensis were 80.08%and 79.80%,respectively.Both treatments above-mentioned were consistently significantly better than other treatments.Therefore,in actual production,it is recommended to apply
