施設栽培のメロンにおけるヘヤカブリダニ（ダニ目：カブリダニ科）を用いたミナミキイロアザミウマ（アザミウマ目：アザミウマ科）防除の検討

抄録

We evaluated the effectiveness of using an indigenous generalist predatory mite, Neoseiulus barkeri（Hughes）（Acari: Phytoseiidae）, to control Thrips palmi Karny（Thysanoptera: Thripidae）in greenhouse melons. In a growth chamber experiment, the density of T. palmi was lower on plants exposed to 20 N. barkeri per plant than on plants grown without a biological control. In a greenhouse experiment, the density of T. palmi was lower in the N. barkeri release plots than in the no-release plots. These results suggest that N. barkeri is an effective biological control agent against T. palmi.
