Embodiment 1

[0013] Embodiment 1 The method of using Neoseius pasteruii to prevent and treat the small clawed mite of chestnut

[0014] In 2007, the Changli Fruit Tree Research Institute of the Hebei Academy of Agriculture and Forestry Sciences screened out Neoseiulus barkeri in Yanshan, Hebei. From 2009 to 2012, artificially reared Neoseiulus barkeri was released in chestnut orchards with different conditions in Yanshan. In the experiment of preventing and controlling Clawed mites on chestnuts, we invented the method of using pesticides only once a year after chestnut leaves unfold to prevent and control various pests and mites in chestnut gardens in spring, and then released Neoseius pasteruii, so that Clawed mites are affected all year round. control, no longer rely on chemical control methods.

[0015] The method of releasing Neoseius pasteruii to control the chestnut mite:

[0016] Chemical control: In the first ten days of May, after the peak period of the emergence of the chestnut ...

Abstract

The invention relates to a biological control method of chestnut red spider mite. Before neoseiulus barkeri is released, low-toxicity pest-killing acarid-killing pesticide is sprayed onto chestnut trees which are damaged by insect pests such as the chestnut red spider mite and aphids according to the insect pest situation, then the neoseiulus barkeri is released to serve as an natural enemy, the neoseiulus barkeri preys on the chestnut red spider mite, and insect pest control is achieved. The low-toxicity pest-killing acarid-killing pesticide comprises, but not limited to, at least one of mineral oil emulsion, myzus persicae, acetamiprid, pyridaben, hexythiazox, spirodiclofen and the like. By the adoption of the biological control method of the chestnut red spider mite, sustainable control over the chestnut red spider mite can be achieved, the number of application times and the application amount of chemical pesticide to the chestnut trees are reduced, pesticide residues are reduced, the food safety of chestnuts is improved, and ecological environment protection is facilitated.

Description

technical field [0001] The invention belongs to the field of biological control of agricultural pests, and in particular relates to a biological control method of the claw mite. Background technique [0002] Chestnut is a tall tree, which is mainly planted in mountainous areas and is in a semi-wild state. There are few types of pests and diseases that cause harm, and it is suitable for organic cultivation. Chestnut small claw mite (Oligonychusununguis) is the most important target pest in chestnut cultivation. It is a disaster all the year round in chestnut-producing areas, with 6-12 generations of reproduction a year. The damage period occurs from May to September, and the peak period is from June to July period, overwintering eggs appear in early and mid-August. Symptoms of damage are mainly manifested as leaf chlorosis, leaf color is almost white, and photosynthesis is lost, which seriously affects the yield of chestnut and the growth of tree vigor. Chemical control nee...
