We conducted this study on the “Black Beauty” variety from Russia, which was planted in a 120 sqrm greenhouse in the Agropark Center of the Mongolian University of Life Sciences in 2017. During vegetation period of egg plant were occurred the polyphagous insect pests such as two spotted spider mite (Tetranychus urticae), тrips (Thripidaes.sp), peach aphid (Myzodes persicae) and caused a injury at 1-2 rate.  For controlling these arthropod pests, we have used 4 different  treatments as А-(predatory mites- Phytoseilus persimilis, Amblyseius swirskii) ), B- (Neem oil), C- (Predators+Nеем oil), D-BEB (LC) 2% as comparing to control plot. In calculating the effectiveness of treatments, А-(predatory mites- Phytoseilus persimilis, Amblyseius swirskii) -79.1%, B- (Neem oil)-73.7%, C- (Predators+Nеем oil)-85.5%, D-BEB (LC) 2% -83.1% as comparing to control plot were killed respectively. We have tested 4 different treatment including the predacious mite (Phytoseiulus persimilis) to control  a two spotted spider mite (TSSM)-Tetranychus urticae) and A.swirskii against trips on the eggplant field . The treatments have been included A (predatory mite alone at 1:5 ratio), B (P+N (predatory mite at 1:5 ratio+Neem oil), C-neem oil alone), LC+BEB 2% and control plots with 4 replications. We have assessed the efficacy of each control treatment, and the B ( predatory mite+neem oil) treatment has reduced TSSM densities at most. These treatments for controlling the pests was  increased the eggplant yield 3.8-36.4% per sqm  area comparing to control plots. There was observed a differences between yield of  control and treatment plots and observed as A plots  (t=2.19, d.f.=174, p≥0,29), B plots  (t=0.88, d.f.=174, p≥0,37),C  plots  (t=8.8, d.f.=174, p≥3.78) as shown on the result of T-test analysis of SPSS.   Цэсийн (solanum melongеna) талбайд тархсан үе хөлтөн хөнөөлт организм (шавж, хачиг), тэдгээртэй тэмцэх биологийн аргын үр нөлөөг судалсан дүн Хураангуй: Бид энэхүү судалгааны ажлыг 2017 онд ХААИС-ийн Агропарк Сургалт, судалгааны төв дэх  120 мкв нийлэг хальсан хүлэмжинд тариалсан цэсийн ОХУ-ын “Чёрная красавица” сорт дээр  гүйцэтгэв.

Abstract Background The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a major pest of strawberry. It was necessary to control this mite pest that can reducing the quality and quantity of the fruits. In this regard, the effect of ZORO acaricide, Neoseiulus californicus (McGregor) and Amblyseius swirskii Athias-Henriot for suppressing the naturally occurring T. urticae populations on three strawberry cultivars were investigated. Results The two predatory mites and ZORO treatments significantly suppressed the populations of T. urticae below the control in all tested cultivars. In most cases of the current study, significantly lower numbers of T. urticae were generally observed in ZORO and N. californicus treatments compared to A. swirskii treatment. In all cultivars, the overall mean of reduction percentages of T. urticae populations in N. californicus and ZORO treatments were not statistically different, and all were significantly higher than that in A. swirskii treatment. Conclusion The present results suggested that the release of N. californicus and the application of ZORO acaricide could be promising strategies for controlling T. urticae on strawberry, although the release of N. californicus appears to be more competent tactic than ZORO acaricide.
