Abundance of Some Sucking Pests on Three Eggplant Cultivars With the Utilization of the Phytoseiid Mite, Phytoseiulus persimilis Athias–Henriot for Controlling Tetranychus urticae Koch

| Abstract |
Abundance and fluctuation of the three sucking pests, Tetranychus urticae Koch, Aphis gossypii Glover and Bemisia tabaci (Gann.) were studied on three eggplant cultivars (Baladi-white, Florida Market and Baladi-Black) during two successive seasons 2009 and 2010. T. urticae occurrence continued almost all the season and reached its maximum at the end of June or the beginning of July; A. gossypii reached the highest abundance in the middle of September while B. tabaci reached the maximum abundance at the end of July and first half of August. Variance in susceptibility among tested cultivars was recorded on bases of the abundance averages overall the two seasons. Florida Market, Baladi-White and Baladi-Black were the most resistant cultivars against T. urticae, A. gossypii and B. tabaci, respectively. On the other hand Baladi-White, Baladi-Black and Baladi-White were the most susceptible cultivars to the same pests, respectively. Phytoseiulus persimilis proved to be a good biocontrol agent against T. urticae at release ratios of 1:5 and 1:10 prey : predator. A reduction appeared one week after release, generally it revealed 68.60 and 88.20 % mean reduction ratio for both release ratios, respectively.
