Abstract
For evaluating lethal effects of abamectin on T. urticae leaf dipping method was used. Then T. brassicae adults were treated with LC<sub>10</sub> and LC<sub>50</sub> values obtained from probit analysis of the mite bioassay results using toxicity bioassay with fresh residue method. For evaluating residual effects of abamectin, bean plants were sprayed with twentieth of recommended field dose of abamectin (equal to 25 ppm of trade product). Leaf pieces were prepared from treated plants in different time intervals and the adult mites were transferred on them. Mortality was recorded after 24 h. Probit analysis of lethal experiment against T. urticae revealed 0.05, 0.417 and 3.26 ppm from trade product as LC<sub>10</sub>, LC<sub>50</sub> and LC<sub>90</sub> values, respectively. Results of residual effects experiment showed that mite mortality was 100% in 1 day after plant spraying which decreased to 55.62% in 21 days after spraying. LC<sub>10</sub> and LC<sub>50</sub> values of abamectin tended to 53.87 and 72.57% mortality of T. brassicae, respectively.
