| Abstract | ||
| A semi-field experiment was carried out at Plant Protection Research Institute, Dokki, Giza under green house conditions, to evaluate the effect of the predatory mite, Phytoseuiluspersimilis as a predaceous mite and the crude extract of Lantana camara (2 g / liter water) in addition to the acaricide, Ortus 5 % EC at the rate of 2 ml /liter water against the two spotted spider mite, Tetranychus urticae infesting tomato plants.Results indicated that the reduction percentages of the adult stages of the spider mites were 89.7, 50.2 and 76.7 % in 2014 season for Phytoseuilus persimilis , the extract of Lantana camara and Ortus 5 % EC , respectively , while the reduction percentages were 94.6,74.1, and 81.7 % for spider mite eggs , respectively. Meanwhile , results indicated that the reduction percentages of the adult stages of the spider mites were 91.7, 48.6 and 76.3 % in 2015 season for Phytoseuilus persimilis , the extract of Lantana camara and Ortus 5 % EC ,respectively , while the reduction percentages were 93.7,72.5, and 82.0 % for spider mite eggs , respectively. | ||
