The relation between body weight and resistance to γ‐BHC and diazinon was studied in experiments using the desert locust ( Schistocerca gregaria ) and the African migratory locust ( Locusta migratoria migratorioides) . In all experiments with Schistocerca , resistance was proportional to weight within any one age and sex group. Resistance to diazinon (per unit body weight) decreased with age, that of the males at a faster rate than that of the females. Against γ‐BHC the insects showed a nearly twofold increase in resistance about 1 week after fledging. Within groups of Locusta the resistance to diazinon was found to be independent of weight, but the resistance to γ‐BHC was dependent on weight. Similarly the resistance to diazinon at different ages after fledging was independent of age but resistance to γ‐BHC increased with age.
