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.https://revistas.inia.es/index.php/sjar/article/view/15241american bollwormgenetic resistanceinsecticide resistance |

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. |
