Abstract
Evaluating the efficiency of release different levels of the predatory mite N. ca/ifamicus (McGregor) for controlling of T urticae and P. uImi. The predatory individuals were 10, 20 and 30/ young apple. The predatory mite N. califomicus released on young apple for controlling T urticae in 2nd April 2006 when spider mite T. urticae infestation reached about 3.73,3.06 and 4 individuals/ leaf, while the predatory mite released for controlling P. ulmi in 10th April 2006 when its infestation reached about 3, 2.93 and 3.23 individuals I leaf at levels at the same levels of predators/ apple tree, respectively. After release the predatory mite N. californkus for control the two spotted spider mite T utticael The percent of redaction was 54.37, 60.81 and 66.89% at levels 10, 20 and 30 predators/ apple trees after four months of release, while after release the predatory mite for control P ulmi on apple tree the percent of redaction was 64.35, 70.20. and 77.66% at the same levels after four months of release.
