Abstract
The two-spotted spider mite Tetranychus urficae Koch and European red mite Panonychus u/m/(Koch) (Family: Tetranychidae) are considered the important two spedes mite pests attacking apple trees causing serious damage of leaves and fruits. To enhance the exportation and reduce the applications of pesticides. We concern in this study to use the coccinellid insect Stethorus gilvifrons Mulsant as biocontrol agent for controlling this dangerous mite pests on apple seedlings. The predatory insect was reared on the two-spotted mite, Tetranychus urticae Koch and released at three levels 5, 10 and 15 adult predator per apple seedling at level infestation 4.23, 4.03 and 4.26 mite per leaf, respectively, while, the untreated one 4.96 individuals/leaf as a control. After releasing the predatory insect the mite pest, T unkae population generally declined gradually and reduction percent in the population of mite pests after 110 days of releasing reached 75.69, 89.1 and 92.9%, respectively. While the predator insect was released at the same levels 5, 10 and 15 adult predator per apple seedling to control P. ulmi with level infestation 2.33, 2.96 and 3.26 individuals per leaf apple seedlings, respectively. While the untreated one 3.66 individuals/leaf. The percentage redaction in the population of P. ulmi after 110 days alter release the predatory insect reached 63.39, 73.57 and 78.33%, respectively.
