Abstract
The biology of Typhlodrompis swirskii (Athias-Henriot) fed on different associated phytophagous mites, insects and
pollens was studied at 25o C. These were Eutetranychus orientalis (Klien) (immatures and adults), Cenopalpus pulcher
(C. & F.) females, Panonychus ulmi (Koch) (females), Tetranychus urticae Koch (immatures and eggs), Tydeus
californicus (Banks) moving stages; whitefly Bemisia tabaci (Gennadius) (eggs and 1st & 2nd instar nymphs), the scale
insects Chrysomphalus ficus Rilly and Coccus hesperidium (Linnaeus) (eggs and nymphs), the aphid Aphis duranta
Theo (adults), date palm pollens Phoenix dactylifera L. and castor bean pollens Ricinus communis L. Amount of
consumption, as well as the predation capacity were estimated. Mites and date palm pollens were more suitable than
insects and castor bean pollens; also immatures of E. orientalis gave the shortest female life cycle (10.8 days) and the
highest female fecundity (38.0 eggs/♀). Feeding T. swirskii on E. orientalis immatures at 15, 20, 25, 28, 30, 32 and
35oC, the developmental durations averaged 18.5, 14.3, 10.8, 9.0, 7.7, 6.8 and 6.1 days respectively. The intrinsic rate
of natural increase (rm) and the net reproduction (Ro) represented the best values 0.269 and 26.48 respectively at 32oC
the mean generation time decreased with increasing temperature (10.971 days at 35oC).
