Studies were conducted on the occurrence of metabolic mediated resistance in cotton aphid, Aphis gossypii to selected insecticides viz., endosullan, monocrotophos, dimethoate, phosphamidon, carbaryl and cypermethrin using synergist TPP in 1:10 and 1:5 ratios. The resistant aphid population of Warangal district exhibited significant TPP suppressible metabolic resistance even at 1:5 ratio in respect of monocrotophos and cypermethrin.
