A Field trial was conducted to study the incidence and management of Bemisia tabaci and Amrasca biguttula biguttula. The peak incidence was recorded during the third week of February 2006 and which the incidence had non-significant relationship with abiotic factors but significant relationship with abundance of coccinellid predatory beetles as well as spiders. The results indicated that thiamethoxam @ 0.005% and combination treatments of thiamethoxam @ 0.0025% + novaluron @ 0.05% and thiamethoxam @ 0.0025% + azadirachtin @ 0.15% were highly effective in reducing the population of B. tabaci and A. biguttula bigutula on brinjal besides recording higher fruit yield.
