The toxicities of the insecticides γ‐BHC, diazinon, dieldrin, DNC, heptachlor and parathion to fifth‐instar hoppers of the desert locust were determined. Parathion and dieldrin were the most toxic, followed in descending order by heptachlor, γ‐BHC, diazinon and DNC. The resistance of the hoppers to γ‐BHC and DNC changed appreciably with age within the instar. The effects of some factors which might influence the resistance of the insects were examined and are discussed.
