Abstract
In this study, the evaluation of some control methods against the two-spotted spider mite, Tetranychus urticae Koch on Soybean plants, Glycin max L.was carried out under field conditions at Beni-Suif Governorate, Egypt in season 2018.The predatory mite Phytoseiulus persimilis Athias-Henriot, (Acarina: Phytoseiidae), and The acaricide (Sanmite) 20%WP were tested. Obtained results showed that the total average number of the mite population was significantly  different with control (F=  75.37, P < 0.0001 & EV = 87.6%), with the mean reduction percentage of significance (F= 56.31, P < 0.0001 &  EV =  84.07%).The mean reduction percentage of the mite population on soybean plants cultivars using the released predatory mite P. persimilis  at rate of 30 adult predators/soybean plants seedling was significantly the highest reduction (83.84%), followed by (Sanmite) (78.66%). The second trial included the released predator at levels 20 and 10 adult predators/soybean plants seedling and gavethe highest reduction at thelevel of 20 adult predators/soybean plants seedling (72% and 62.55%). It could be concluded that the using P. persimilis at rate of 30 adult predators/Soybean plants for controlling T.urticae was superior than using The acaricde , Sanmite 20% (WP).
