Abstract
Relative toxicity of fluvalinate, triazophos, dimethoate and endosulfan were bioassayed with their LC50 values as 1.0617 x 10, 3.9235x 10, 18624x 10' and 5.6557 x 10 , respectively against Aphis gossypii Glov. at 15+1°C and 70+5% RH. The fluvalinate evaluated the most toxic whilst endosulfan the least toxic insecticide.
