The influence of post‐treatment temperatures of 5, 10, 17 5, and 25°C on the efficacy of three pesticides, Karate (10 g a i/ha lambda cyhalothnn), Sumicidin 10 (30 g a i/ha fenvalerate), and Afugan (294 g a i/ha pyrazophos), applied to Poecilus cupreus (Coleoptera Carabidae) was investigated in the laboratory The results indicate a negative correlation between the temperature and the effects of all three products With the two pyrethroids Karate and Sumicidin, the recovery period of knocked down beetles and their food consumption showed this negative temperature correlation The reason seems to be a temporarily arrested detoxification of the pyrethroids inside the beetles at reduced temperatures Final mortality seven weeks after application of pyrethroids was unaffected by temperature With the organophosphorus compound pyrazophos final mortality was negatively correlated with temperature Male beetles seemed to be more sensitive than females with all products and temperatures
