Extract

Three volatile solid insecticides (DFDT, γ BHC and aldrin) were tested against two species (Oryzaephilus surinamensis and Tribolium castaneum) at two temperatures (30°C. and 11°C.) in simple laboratory fumigation tests. DFDT killed both species faster at 11°C. than 30°C.; γ BHC killed O. surinamensis faster at 11°C. than 30°C., but T. castaneum faster at 30°C. than 11°C.; aldrin killed both species faster at 30°C. than 11°C.
