摘　　要：采用叶管药膜法测定了金龟子绿僵菌CQMa421与新烟碱类农药噻虫嗪、噻虫胺、吡虫啉、啶虫脒按照有效成分比(1∶9、3∶7、5∶5、7∶3、9∶1)混配对西花蓟马的室内毒力。结果表明,4种新烟碱类杀虫剂的24和48 h毒力为噻虫胺>噻虫嗪>啶虫脒>吡虫啉,均高于金龟子绿僵菌CQMa421。绿僵菌与噻虫嗪和吡虫啉分别以1∶9、3∶7、5∶5、7∶3、9∶1的比例混配均具有显著的增效作用,绿僵菌与噻虫胺和啶虫脒以9∶1、7∶3的比例混配亦具有良好的增效作用。绿僵菌与新烟碱类农药混配有助于提高对西花蓟马的室内毒力,为治理西花蓟马对新烟碱类杀虫剂抗性提供理论依据。In this study,leaf tube film method was used to determine the indoor virulence of Metartaria anisopliae CQMa421 mixed with neonicotinoid 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 thiamethoxam and imidacloprid(1∶9,3∶7,5∶5,7∶3,9∶1)had significant synergistic effect.Metarhizium anisopliae mixed with clothianidin and acetamidine(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.
