球孢白僵菌与减量农药联用对茶丽纹象甲成虫的防控效果
Control of Adults of Myllocerinus aurolineatus Voss by Combining Beauveria bassiana with Reduced Pesticide
摘要
Abstract
This study aimed to investigate the efficiency of Beauveria bassiana in conjunction with a reduced pesticide in controlling the adult population of Myllocerinus aurolineatus Voss,employing a potted plant experiment and a field experiment by using 100 billion spores/g Bb338 of wettable powder,1.3%soluble matrine,and 25g/L bifenthrin EC.Among the six biocontrol fungi,Bb338 had the highest toxicity to the weevil with the shortest LT50 value(4.005 d)and the highest corrected mortality(100%)at 8 d post treatment.The potted plant experiment showed that the control efficiency of Bb338 combined with 50%-reduced matrine was 20.00%and 17.58%higher than that of Bb338 alone at 3 d and 5 d post treatment,respectively,similar to that of 25%-reduced matrine alone but higher than that of 75%-reduced matrine alone.The control efficiency of Bb338 combined with 75%-reduced bifenthrin EC was 95.06%at 10 days post treatment,higher than that of Bb338 alone.The field experiment showed that the control of Bb338 combined with 50 g/L bifenthrin EC was the highest at 3 days post treatment,higher than that of Bb338 alone and Bb338 combined with 50%-reduced matrine.At 25 days post treatment,the control of Bb338 combined with 50%-reduced matrine was the highest(67.70%).The combined applications of Bb338 and matrine or bifenthrin have significant synergistic effects on M.aurolineatus.关键词
