| Abstract | ||
| The research was carried out in the laboutaries of State Board for Agricultural Research, Ministry of Agriculture, during the year 2009 to study the effect of three kinds of plant water extract used to control of the two spotted spider mites Tetranychus urticae Koch. . Water extracts were, Citrullus colocynthsis (fruits) and Dianthus carphyllus (fruits). The last was Lantana camara (leaves ). Three concentration 0.5,1 ,2 g/L , for each extracts . The leaf disc methods used for preparing di fferent stage of spider mites. The result showed that hundull and koronfull extracts were more effective than mena showjery in prevention of eggs hatching of TSSM .The percent was 100.0,96.1 and 50.9 % respectively when the concentrat of 2g/ L of extracte were applied. Then the percent decrease to 79.1,83.1 and 40.2 % respectively using 1g/L concentrate .However the concentration 0.5 g/L indicates lower effects on egg hatching (38.4,76.5,55.0)% respectively.Similar effects were obtained when water extracts applied against nymph stages of TSSM . mortality percent 94.0, 90.0 and 20.6 % ,82.3,85.6 and 0.0 %, 80.0, 70.3 and 0.0 % respectively . | ||
