Synergistic Effect of Metarhizium anisopliae CQMa421 Mixed with Four Neonicotinoid Pesticides on Virulence of Frankliniella occi-dentalis
In this study,leaf tube film method was used to determine the indoor virulence of Metartaria anisopliae CQMa421 mixed with neoni-cotinoid pesticides(thiamethoxam,thiamethoxidin,imidacloprid,and amidine)in different active component ratios(1∶9,3∶7,5∶5,7∶3,9∶1).The results showed that the virulence of four neonicotinoid pesticides at 24 h and 48 h was in the order of thiamethoxam＞thiamethoxam＞acetamidine＞imidacloprid,which was higher than that of Metarium anisopliae CQMa421,but the mixture of Metarium anisopliae with thiame-thoxam and imidacloprid(1∶9,3∶7,5∶5,7∶3,9∶1)had significant synergistic effect.Metarhizium anisopliae mixed with clothianidin and ac-etamidine(9∶1,7∶3)also had a good synergistic effect.It can be seen that the mixture of Metartaria anisopliae and neonicotinoid pesticides can alleviate the pesticide resistance,which provides a reliable scientific basis and a new way for the resistance management of neonicotinoid pesticides in Frankliniella occidentalis.
