Establishment of the farmer support system in use of natural enemies of pests by development of the simple growth chamber

为了支持环境友好型农业的进一步发展，我们创新了一种相对简单的害虫（蜘蛛螨）的天敌（掠食性螨）多耕系统，可供农民使用。并研制了简单的天敌运输船系统。同时对日本东南部的天敌（食螨）区系进行调查，共采集鉴定成螨1070只（其中雌螨862只）。

To support the further development of environmentally friendly agriculture, we innovated a relatively simple multi-cultivation system of natural enemy(predacious mite) of pest(spider mite), which can be used by farmers. The simple transporting vessel system of natural enemy was also prepared. At the same time, natural enemy(predacious mite) fauna was surveyed in southeastern Japan and 1, 070 adult mites(including 862 females) were collected and identified.
