دراسة سلوك انتشار المفترس الاكاروسي Phytoseiulus persimilis Athias- Henroit على الفريز في الزراعة المحمية

The study was carried out at a greenhouse in Lattakia center for rearing natural enemies, during 2005-2006 and 2006-2007, on strawberry plants infected with the spider mite Tetranychus urticae Koch, using the predatory mite Phytoseiulus persimilis Athias- Henroit, as a biological control agent, to know its efficacy to dispersal and search for its prey, after starving. Results showed the efficacy of this predatory mite to dispersal. They also showed that the time it took depended on the extent of starving. Results also indicated the efficacy of the predatory mite (after four weeks) in controlling the prey and reducing its population density.
