Dose–mortality curves were established for 12 insecticides administered by topical application to diapausing larvae from a susceptible codling moth strain. Toxicity varied greatly among the insecticides tested. LC 50 values ranged from 0.1 mg kg −1 for fenoxycarb to over 2800 mg kg −1 for diflubenzuron and indoxacarb. Discriminating dose levels were determined from dose‐mortality reference curves for the detection of resistance in field‐collected diapausing larvae. Copyright © 2003 Society of Chemical Industry
