Species mass rearing technology for effective entomophages of harmful thrips in biolaboratories and their significance

摘要

Scientific investigations devoted to technologies of mass rearing in biological laboratories of natural occurring species of entomophage of pest thrips are stated in this article. The technology of phytoseiulus rearing (Phitoseiulus persimilis Ah.) in the laboratory has been developed. According to this technology, rearing of phytoseiulus is conducted on legumes. At the same time, plants were grown in separate rooms, depending on their phases of development. With the formation of 15-20 leaves, the plants were infected with a spider mite. The air temperature was kept at 25-27°С, and the relative humidity was 65-70%. In such conditions, after 7-8 days, the number of spider mites on plants decreased, and the number of predatory mites increased. The entomophages collected from plants placed on vegetables crops. Plants in the laboratory were planted at the same time, which contributes to the frequency of collection of the entomophage.
