The mites Amblyseius cucumeris and Amblyseius barkeri are used in biological control commercial program against Frankliniella occidentalis. The diapause influence is essential to know the efficacy in climatic extreme conditions. The experiments were designated to verify the following: a) the effect of night temperatures on diapause induction; b) the effect of continuous darkness and low temperatures on diapause induction. In the first case A. cucumeris at 12 degrees C temperature in ecotophase diapause incidence was 100%. A. barkeri was not affected by 3 night temperatures. In the second case it could be seen that the test conditions did not induce diapause in either case.
