Mass rearing method of predatory mite

Abstract

The invention discloses a predatory-mite large-scale feeding method. An adopted feeding device comprises a box body, a box cover and at least one feeding frame. A water tank around the box body is arranged at the edge of the top of the box body; a body of each feeding frame is composed of a net-shaped flat plate and climbing branches, wherein the climbing branches are arranged on the periphery of the net-shaped flat plate and horizontally extend outwards to be in contact with the inner wall of the box body; supporting legs are arranged at the bottoms of the feeding frames, and the multiple feeding frames are stacked together. The feeding method includes the steps that flour mites or fruit mites are artificially fed with wheat bran; the wheat bran with the flour mites or the fruit mites is laid on the feeding frames of the feeding device to serve as feed of predatory mites; then the predatory mites are inoculated into the feed, water is injected into the water tank, and the box body is covered with the box cover for feeding, wherein the feeding conditions include the temperature of 20 DEG C to 28 DEG C, the relative humidity of 75% to 85%, and the light-darkness ratio of 12 h to 16 h:8 h to 12 h; in the feeding process, the box cover is opened once a day for ventilation, and packaging can be carried out when the number of the predatory mites meets packaging requirements.

Description

technical field [0001] The invention belongs to the field of biological control of agricultural pests, and in particular relates to a method for feeding predatory mites in large quantities. Background technique [0002] Biological natural enemies to control field pests (mite) have the advantages of environmental protection, conforming to the laws of nature, strong specificity, long-lasting effect, and no chemical residues. They are widely used in organic food, greenhouses and other crops. [0003] Predator mite is a kind of omnivorous beneficial mite whose main food is citrus red spider mite, yellow spider mite, rust tick, hawthorn spider mite, cinnabar spider mite, apple spider mite and other plant spider mites. Predator mite is used to control and control citrus Orange red spider, yellow spider and rust tick can replace chemical control to control citrus pest mites, and it is one of the important technologies to produce pollution-free and green citrus. Predatory mite is a...

Problems solved by technology

The traditional breeding method has the following disadvantages: (1) The anti-escape water container is located at the bottom of the rearing box. Although it can prevent the predatory mites from escaping to the outside world, the predatory mites are limited to the breeding box, and the climbing space is small, and the predatory mites are mostly concentrated in the breeding box. The wall of the breeding box and the surface layer of wheat bran are active, and other spaces cannot be reached, which limits the activity of the predatory mite and is not conducive to the growth of the predatory mite and the hunting of prey after being released in the field; Adding new wheat bran on the basis of bran will increase the pressure of the bottom layer, the air will not circulate, the predator mites and acaroid mites will suffocate to death, the population growth will be slow, and the production efficiency will be low
