Abstract
The life-history parameters of Phytoseius plumiter (Canestrini & Fanzago) were studied in the laboratory using immature stages of the two-spotted spider mite Tetranychus urticae Koch as a food source at seven temperature degrees (15-±19C - 35±19C). Life cycle (egg — adult emergence) lasted for 33.3, 16.6, 9.6, 8.7, 7.9, 7.4, and 7.1 days when female was maintained at 15, 20, 25, 28, 30, 32, and 35'C, respective­ly, and 70% R.N. Mean daily oviposition increased as temperature in­creased till reaching 32'C (2.0 eggs). The intrinsic rate of natural in­crease (rm) reached its maximum value (0.241 individuals / female / day) at 329C. This predator was able to survive and reproduce with vary­ing degrees of fecundity and predacious ability on the two-spotted spi­der mite T. urticae Koch (adults), the red spider mite T. cucurbitacearum (Sayed) (immatures and adults), the citrus brown mite Eutetranychus orientalis (Klein) (immatures), the eriophyid ploughman's spikenard gall mite Eriophyes dioscoridis Soliman and Abou-Awad (active stages), the whitefly Bemisia :abaci (Gennadius) (eggs), the scale insect Padatoria zizyphus (Lucas) (eggs), and the date palm Phoenix dactylifera L. (pollen grains).
