Abstract
Neoseiulus californicus was released in three levels 10, 20, 30 against T.urticae and A.gossypii separately and compared their percentage reduction in case exist together on the same host. The percentage reduction of N.californicus under the area in greenhouse cultivated with phaseolus vulgaris and infested withT.urticae only at the level of releasing 10 individuals per plot were 11.5, 21.6, 33.8, 35 and 39.5 compared with 12.3, 26, 41.8, 47.7 and 58.7 from the plot infested with T.urticae and A.gossypii together.





          The data revealed that the percentage reduction as a result of N.californicus release against A.gossypii only at level of releasing 10 individuals per plot were 9, 21.9, 35.6, 37 and 42.8 compared with 15.7, 20.7, 28.8, 29.3 and 36 from the plot infested with T.urticae and A.gossypii together on of the same host plant. Also the percentage reduction of A.gossypii at levels of releasing 20 and  30 individuals per plot were 14.2 , 31.3 , 39.5 , 44.3 , 55.9  and 14 , 43.8 , 47.4 , 60 and 72 , respectively compared with 16.3 , 20.6 , 40 , 41.2 and 51.5 , 15.7 , 25.5 , 55 , 62.5 and 72.6when A.gossypii was with T.urticae on of the same host plant. N. californicus has proved to be a promising candidate for biological control of T.urticae and A.gossypii. The percentage reduction of the predator mite is higher when the two previous pests occurred together on the same host plant than separately.
