After six weeks of release of ten female &lt;em&gt;T. urticae &lt;/em&gt;in control plants, the highest mite population reached at 184.21 / leaf, against 67.92 and 107.48 / leaf in plants which received two predators after 1st and 3rd week respectively. After nine weeks the number of mite / leaf reduced to 13.21 and 23.97 / leaf after 1st and 3rd week of introduction of the predator, the control population was 81.32. Adult &lt;em&gt;P. persimilis &lt;/em&gt;as single predator fed 8.2, 15.4 and 20.6 &lt;em&gt;T. urticae &lt;/em&gt;eggs after 24, 48 and 72 h respectively. Again a single predator when tested separately fed 5.4, 10.8 and 14.6 &lt;em&gt;T. urticae &lt;/em&gt;larvae after 24, 48 and 72 h respectively. A single adult predator fed on 3.6, 7.0 and 12.0 adult &lt;em&gt;T. urticae &lt;/em&gt;after the same durations. When varying number (10, 20, 30, 40 and 50) of prey (larvae or adults) were provided to a single predator it fed 5.0, 6.6, 6.8, 9.0 and 9.4 larvae against 3.2, 3.2, 3.4, 3.6 and 3.6 adults respectively.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Key words: &lt;/strong&gt;Predation, spider mite, eggplant, voracity, release.  &lt;/p&gt; &lt;p&gt;doi: 10.3329/jbs.v15i0.2152&lt;/p&gt; &lt;p&gt;J. bio-sci. 15: 127-132, 2007&lt;/p&gt;}, journal={Journal of Bio-Science}, author={Khalequzzaman, M and Mondal, Mina and Haque, M Fazlul and Karim, M Sajedul}, year={2009}, month={Mar.}, pages={127–132} }
