| Abstract |
Biological control of Tetranychus urticae Koch, in Sharkeia Governorate's commercial cucumber fields, is possible by using of the predacious mite, Phytoseiulus persimilis Athias-Henriot.
During the two successive seasons, 2003 and 2004, the predator mite, P. persimilis A.-H. was released at a the rate of 20-25 individuals/bit to control the two¬ spotted spider mite, Tetranychus urticae Koch, in about 196 m2 planted with commercial cucumber, variety Botaseed, in El-Gahpharia, Sharkia Governorate.
In the first season (2003) the reduction of spider mite reached 98% after 7 weeks from release compared with the control while in the second season (2004) the reduction reached 97% after about 8 weeks from release. Immigration of the predator to the buffer area contributed to pest reduction. The cost is likely to be lower than that of chemical control and cucumber yield not reduced.
