Degress of TPP suppressible resistance acquired by Aphis gossypil Glover to selected insecticides

Studies were conducted on the occurence of metabolic mediated resistance in cotton aphid, Aphis gossypil to selected insecticides viz., endosulfan, monocrotophos, dimethoate, phosphamidon, carbaryl and cypermethrin using synergist TPP suppressible metabolic resistance even at 1:5 ratio in respect of monocrotophos and cypermethrin.
