To establish effective control against thrips which damages broad bean in open field cultivation, inoculative release of predatory mite, Amblyseius swirskii Athias-Henriot, was evaluated under greenhouses and open field conditions from October to December in Kagoshima, Japan. The dominant species of thrips was Thrips hawaiiensis(Morgan) in this present study. Population densities of thrips when A. swirskii was released were significantly lower than non-treatment trial under the both conditions; greenhouses and open field cultivation. The timing of release before or during blooming period and releasing method with bottles or resin bags of predatory mites affected significantly the densities of thrips or predatory mites on broad bean. We might use A. swirskii successfully by releasing ones with bottles before blooming of broad bean. Furthermore, alyssum as insectary plants was considered to be effective to enhance the population growth of A. swirskii on broad bean.
