Method for efficiently propagating phytoseiulus persimilis in large scale

The invention discloses a method for efficiently propagating phytoseiulus persimilis in a large scale. The method is characterized by comprising the following four parts: planting host plants of nightshade and bean seedlings, feeding spider mites, inoculating and propagating the phytoseiulus persimilis, and harvesting the phytoseiulus persimilis. Solanum nigrum is adopted for spider mite breeding, the host plant solanum nigrum is planted in batches in a planned mode according to the requirements of phytoseiulus persimilis, and then leaves and stalks of the solanum nigrum are inoculated to bean seedlings. Due to the fact that the black nightshade is high in spider mite breeding speed and high in insect pest resistance, enough spider mites can be obtained at any time through the method, and the propagation expanding efficiency is improved by 25%. 本发明公开了一种高效规模化扩繁智利小植绥螨的方法，其特征是包括寄主植物龙葵与豆苗的种植、叶螨的饲养方法、智利小植绥螨的接种与繁殖、智利小植绥螨的收获四部分。本发明采用了龙葵进行叶螨繁殖，并根据智利小植绥螨的需求，有计划的分批种植寄主植物龙葵，然后将龙葵叶、茎秆接种到豆苗上。由于龙葵繁殖叶螨速度快、耐虫害能力强，通过本方法能够随时获得
