EFFICACY OF CERTAIN COMPOUNDS AGAINST SOME PIERCING SUCKING PESTS ON MEDICINAL AND ORNAMENTAL PLANTS
This study was conducted to evaluate some compounds (Crater, Baiocao and Ashook) againstTetranychus urticae Koch.onpeppermint plants and Brevipalpus obovatus Donn.on marigold plants under laboratory and field conditions. This study was carried out at the laboratory of plant protection research institute and at Damietta governorate during seasons 2007and 2008.The results indicated that, Crater was the most effective compound against T. urticae with Lc50= 0.019 ml and against B. obovatus with Lc50= 0.072 ml. followed by Baiocao and Ashook after 24 hrs. under laboratory conditions. Crater also was the most effective compound against T. urticae and B. obovatus under field conditions. The general mean reduction of T. urtica can be arranged as follows Crater (87.88,86.6; 81.52,80.01& 71.62,73.3%) at (0.6, 0.3 &0.1 ml\l) > Ashook (61.32,63.1; 55.79,55.4 &47.07,51.3) at(3.7, 1.7 &0.9 ml\l). The general mean reduction of B. obovatus individuals can be arranged as follows Crater (78.58, 79.5; 65.88, 66.5 & 64.54, 63.8) at (0.6, 0.3 & 0.1ml\l) > Ashook (56.83, 58.2; 42.57,44.2 & 41.34,42.1%) at(3.7, 1.7 & 0.9 ml\l).during 2007 and 2008 seasons.
