Abstract
The biology of Phytoseiulus macropilis (Banks) fed on Tetranychus urti cae Koch was studied at different temperatures. The total development times averaged 7.5, 5.7, 4.2, 4.2 and 5.6 days at 20, 25, 28, 30 and 3 2 degrees C, respectively at 78 +/- 2% RH and 16 h photoperiod daily. The intrinsic rate of natural increase (r(m)) and the net reproduction (R-o) reached maximum values 0.47 and 88.9, o respectively, at 28 deg rees C. The mean generation time decreased (20.0-8.8 days) with increa sing temperature 20-28 degrees C. (C) 1998 Chapman & Hall Ltd.
