Three field strains of DDT-resistant codling moths from different areas in northern California were mass reared in the laboratory. The degree of DDT resistance in both larvae and adults was determined by using two methods of exposure to the insecticides. Topical applications (LD50) were made to the moths, and the cage technique (LC50) was used for the larvae. ADDT-susceptible laboratory strain of codling moth was used as the standard for comparison.

The tests showed that all three of the field strains were resistant to DDT, but further tests showed no cross-resistance to either the carbamate or phosphate insecticides tested.
