Abstract
The potential resistance to insecticides of Bracon mellitor Say was determined by treating each of 5 test groups for 5 or more generations with an organic insecticide commonly used for the control of cotton insects. Four fold increases in tolerance were noted in groups treated with DDT, carbaryl, and methyl parathion. A group treated with equal parts of DDT and toxaphene had resistance 8 times that of the original generation. Only a group treated with toxaphene alone showed no significant increase in tolerance. The results demonstrated that the parasite has a mechanism for developing resistance to insecticides.This publication has 1 reference indexed in Scilit:
