Reduction of the natural enemy population by deltamethrin and imidacloprid leads to the resurgence of brown planthopper (nilaparvata lugens, hemiptera: delphacidae (stal)) in rice

HIGHLIGHTS

• What: The authors studied the of BPH post application of different insecticides in and assessed the impact of insecticides on population during Rabi 2022-23. consequently resulted in higher BPH greater reduction in predatory mirid bugs and spiders was observed in the deltamethrin and imidacloprid treated groups compared to the untreated check. To better understand the impact of different pesticides on the resurgence of the BPH and their effect on the natural enemy complex in the rice ecosystem, in this study, the authors investigated the induced resurgence of the BPH through repeated application of different pesticide groups . . .
