The two predatory mites, Amblyseius swirskii Athias-Henriot and Cheletogenes ornatus Canestrini & Fanzago were evaluated as early release to control Tetranychus urticae (Koch) on Soybean plants in Sharkia governorate during the period from 15th June to 7th September 2016. Three release levels (2, 4 and 6 predators/leaf) were conducted when population of spider mite was 1-3 individual/leaf. There was no significant difference between the efficiency of the two predators all over the experiment.  Reduction percentages were recorded as 54.3, 69.7 and 78.9% for A. swirskii while it was 48.7, 61.8 and 69% for C.ornatus at three rates of release, respectively. Efficiency increased significantly with predator release rate increase. There was no significant differences between the reduction percentages of 4 and 6 predators/plant. Starting release at low level of infestation to have good control in very short time after releasing is amust.
