Abstract
Laboratory tests in 1960 confirmed 1959 field observations that the pink bollworm (Pectinophora gossypiella (Saunders)) was resistant to DDT in certain areas of Mexico. Topical applications of DDT to moths originating at Tlahualilo, Durango, and Francisco I. Madero, Coahuila, resulted in LD-50's 13.6 and 7.4 times greater, respectively, than the LD-50 of moths originating near El Paso, Texas.This publication has 1 reference indexed in Scilit:
