Abstract:
Field studies carried out during kharif and rabi 2016-17 at Regional Agricultural Research Station, Maruteru (A.P.), India to assess the impact of resurgence inducing insecticides on natural enemies of brown planthopper infesting rice. The results revealed the significant reduction in the population of mirid bug and spiders due to toxic nature of insecticides viz., chlorpyriphos, profenophos, cypermethrin, deltamethrin, bifenthrin, lambda cyhalothrin and imidacloprid (higher prey-predator ratio) may lead to resurgence in the population of brown planthopper. Hence, it is advised not to recommend or minimize their usage in rice ecosystem.
