Abstract
This study was conducted to evaluate the potential of induced resistance by of jasmonic acid (JA) and benzo (1, 2, and 3) thiadiazole-7-carbothioic acid 5-methyl ester (BTH), a functional analogue of salicylic add, against Tetranychus urticae infestation. The data demonstrated that both JA and BTH treatments significantly impair the development of T. urticae compared to control. They reduced the percent of T ufficae infestation especially at optimal rate. Where, 1.5 mM JA-treatment and 1 mM BTH significantly reduced the production of r urlio3e. Evaluation of mite performance revealed that there was highly significant effect of JA, BTH treatments on development of the egg and adult stages, while immature stage slightly affected. On the other hand, data reported that BTH significantly reduced the fecundity of the T. urticae females when compared to JA and control. Therefore, we concluded that JA and BTH increase plant defense against r urticae.
