We examined integration of soil application of azadirachtin with two predatory mite species to control Frankliniella occidentalis (Pergande) on Phaseolus vulgaris. The release of a single predatory mite species reduced thrips numbers only to the lowest degree under this set of experimental conditions. Predator combinations increased corrected thrips mortality ranging from 54 to 85%. NeemAzal-U (17% azadirachtin), a formulation developed for root uptake, caused mortalities from 70 to 98% after soil application. A combination of azadirachtin with predatory mites enhanced not only consistency in thrips control but also resulted in efficacies of up to 99%. The survival of both predatory mite species were not significantly affected by NeemAzal-U soil treatments. However, a significant reduction in population development of H. aculeifer assumed an influence of NeemAzal-U on reproduction of the soil dwelling mites.
