摘要

Aim of study: It is first report to sort out resistance development; its mode and inheritance in Helicoverpa armigera against bifenthrin till several generations using progeny reciprocal crosses and back crosses, combined with observing the cross resistance of bifenthrin against pyrethroid, organophosphate, pyrazole and new chemistry insecticides.Area of study: This study was conducted at agriculture fields of University of Agriculture, Faisalabad, Pakistan.Material and methods: Bifenthrin selected strain of H. armigera was reciprocally crossed to bifenthrin susceptible strains. Resulting F1 progeny was back-crossed to resistant strain. Cross resistance of bifenthrin to six insecticides (cypermethrin, triazophos, emamectin benzoate, fipronil, lambda-cyhalothrin, profenofos) was observed.Main results: Resistance ratio was higher in bifenthrin selected strain. h value showed that resistance was autosomal with incomplete dominance. Polygenic mode of resistance; resistance controlled by more than one gene; was found against bifenthrin in H. armigera. Cross resistance of bifenthrin selected strain against different insecticides was found higher.Research highlights: Reciprocal crosses of F1 progeny combined with LC50 exhibits that resistance can be controlled using multiple insecticides at different intervals against H. armigera. These results can be implicated to develop an integrated pest management strategy to control H. armigera.

Armigera的Bifenthrin选定菌株往复越过Bifthrin易感菌株。产生的F1后代被回到抗抵抗力。观察了二苯胺至六种杀虫剂(Cypetmethrin,三唑辛,苯甲酸苄酯,Fipronil,Lambda-Cyhalothrin,Profenofos)的抗抗抗性。结果:抗血液选定菌株的抗性比较高。 H值表明,具有不完全优势的抵抗力是常染色的。多基因抗性模式;阻力由多种基因控制;在H. Armigera的Bifenthrin发现。发现了比赛林蛋白的抗抗抗杀虫剂的抗抗杀虫剂的抗性。研究突出显示:F1后代与LC50联合的互核交叉表现出阻力,可以使用不同间隔以不同间隔的抗杀虫剂对抗H. Armigera来控制阻力。这些结果可以涉及制定控制H. Armigera的综合害虫管理策略。
