Problems solved by technology

The concentration of pesticides used by growers is getting higher and higher, and the amount of use is increasing, but the damage caused by Tetranychus urticae is difficult to control, which seriously affects the yield and quality safety of agricultural products
[0007] At present, although we have mastered the industrial production technology of A. pachydermis, we have also carried out a field release test of A. pachydermis using leaves as a medium, and achieved good control effects, but using leaves As a carrier for the storage and field release of A. viriciformis, on the one hand, the leaves are easy to rot or dry, and it is not easy to store for a long time; on the other hand, the leaves are not easy to pack, and it is difficult to release in the field

Abstract

The invention provides a method for preventing horticultural crop mites by amblyseius pseudolongispinosus, and belongs to the technical field of biotechnological prevention of agricultural pests. Discoveries show that the mites can be effectively prevented by releasing the amblyseius pseudolongispinosus, and a field application technique of amblyseius pseudolongispinosus products is further determined on the basis. According to the method, after the amblyseius pseudolongispinosus is released in a field for 14 days, control effect of the amblyseius pseudolongispinosus on the mites is higher than that of miticide, persistence is obviously better than that of prevention by chemical agents, and efficient prevention effect comparable with chemical pesticide can be achieved. The method is free of pollution to the environment, long in persistent period and capable of realizing large-scale industrialized implementation.

Description

technical field [0001] The invention relates to the field of crop protection, in particular to a method for biologically controlling pests by using Amblyseius pseudorhizoides. Background technique [0002] Tetranychus are important pests of agricultural and forestry crops, with strong adaptability and wide distribution, and are important control objects. At present, chemical methods are mainly used to prevent and control spider mites, but due to the abuse of pesticides, a large number of natural enemies have been killed, and the rapid development of spider mites' resistance to pesticides has led to the rampant occurrence of spider mites (Zhang Fan et al., 2005), such as damage to cotton, tobacco, fruit trees, corn, etc. The cinnabar spider mite Tetranychus cinnabarinus (Boisduval) of more than 100 economic crops, such as sorghum, beans, melons, and roses (Guo Fengying and Zhao Zhimo, 2001), has developed resistance to a variety of insecticides (mite) (Wu Kong Ming et al., 1...
