Method for breeding pyemotes and method for preventing and treating boring pests by using pyemotes

Abstract

The invention provides a method for breeding pyemotes and a method for preventing and treating boring pests by using the pyemotes. The method for breeding the pyemotes comprises the steps: (1) preparing a first generation of artificial pyemotes species by using larvae and pupae of Chinese bees or Italian bees; (2) making mass breeding species by using the larvae and the pupae of the Chinese bees or the Italian bees; (3), carrying out artificial large-scale breeding of the pyemotes by using the larvae and the pupae of the Chinese bees or the Italian bees ; and (4) packaging and storing. According to the method for breeding the pyemotes, the larvae and the pupae of the Chinese bees or the Italian bees are used as substitute hosts of the pyemotes, so that the breeding cost of the pyemotes can be greatly reduced, the breeding quantity of the pyemotes can be increased, the high activity of the pyemotes species can be kept, and the artificial large-scale breeding of natural enemies of the pyemotes can be really realized; when the pyemotes obtained by the method are used for preventing and treating the boring pests, the pyemotes have a good prevention and treatment effect on the boring pests.

Description

technical field [0001] The invention relates to the technical field of biological control of pests, in particular to a method for breeding cataclysmic mites and a method for preventing and controlling borer-boring pests. Background technique [0002] Boring pests are important pests of forest trees and crops, which bring huge losses to agricultural grain production and forestry ecological environment every year, so it is very necessary to control boring pests. However, the hidden nature of these pests often brings difficulties to the control work. But the cat mite is the natural enemy of various borer pests, and can actively find the hiding place of the borer pests and carry out parasitism. In 2008, Zhang Zuoshuang et al. conducted a parasitism test on the foreign wheat veterinary mite Pyemotestrittci to the two-striped fir beetle, the cypress beetle, the Japanese double-spined beetle, and the six-star black-spotted beetle moth. After 30 days, it was found that the above-me...

AI Technical Summary

Problems solved by technology

[0003] At present, the breeding of natural enemies of cat mites still relies on alternative hosts, mainly barley worm pupae, silkworm pupae, grubs, hairy bark beetle larvae, Taiwan beetle larvae, mung bean weevil, Trichogramma pupae, and yellow powder beetle For pupae, larvae of Cyperus chrysalis, larvae of Shuangtiaoshan longhorn, fish eggs, etc., there are situations where artificial breeding has not been realized for alternative hosts, low breeding efficiency, high breeding costs, and complicated operations

For example, the widely used alternative hosts, Ramie longhorn beetle, Pyramus longifer, Taiwan long beetle, and Shuangtiaoshan beetle have not been artificially bred on a large scale, and they are all collected in the wild. The instability and difficulty of natural populations limit the scale. Breeding

The most widely used alternative host, the chrysalis chrysalis, has achieved large-scale breeding, but because the chrysalis chrysalis is active, the skin is thick and hard, it is difficult for the mites to bite and fix, and the breeding success rate is low

There are also less Trichogramma pupae used. A single Trichogramma pupae is extremely small, has low nutritional content, produces very few offspring, and has relatively high costs, complicated production procedures, and is not suitable for large-scale breeding.

In addition, in the process of storage, transportation and release, the bulging body of the cat mite is fragile and easy to fall off, so its packaging, storage and release are also problems that need to be solved
