Abstract
Occurrence of DDT resistance in the codling moth, Carpocapsa pomonella (L.), is briefly reviewed. A strain of codling moth from an apple orchard at Soquel, California, is shown by laboratory studies to have an LC-50 four times that of a nonresistant laboratory strain. These studies are based on the susceptibility of newly hatched larvae of each strain to initial deposits from different dosages of a DDT wettable powder on apples, using a cell technique. Well-timed applications of DDT in replicated plots in the orchard in which the resistant population occurred resulted in control failure, whereas materials not related to DDT provided excellent control.This publication has 5 references indexed in Scilit:
