Problems solved by technology

[0002] The predatory mite natural enemies developed at home and abroad are mainly concentrated in the Phytoseiidae family (Phytoseiidae) and a few Laelapidae (Laelapidae) species. There are mature precedents for the large-scale breeding and application of these species. cucumeris, synonym: Cucumber Amblyseius), Chilean Phytoseiulus persimilis (Phytoseiulus persimilis), California Neoseiulus (Neoseiulus californicus), etc. to prevent and control spider mites and thrips, using Hypoaspis aculeifer and soldiers Shield mites (H.miles) control thrips (pseudopupal stage), fungus mosquitoes and root mites, while research on cyst mites (Ascidae) is quite small, and research on its potential development and application has basically not been carried out, let alone a large number of studies. Methods of feeding and system application
In recent years, the Netherlands and other countries have successively developed Amblyseius swirskii to control whiteflies in greenhouses, and put it into preliminary commercial production. Amblyseius is not distributed in my country, and the introduction of natural enemies faces quarantine problems

Embodiment 1

[0026] A: Fully mix wheat bran and peat as a feeding medium, sterilize in high-temperature and high-pressure steam, and pack them into feeding containers in a breeding factory after cooling down, and then add acaroid mites for cultivation. After about 5-15 days, they will be cultivated to When 50-500 head / g, inoculated cyst mites; the ratio of inoculated cyst mites and acaroid mites was 1:15 to 1:35. The internal water volume in the feeding container is 20-30% of the feeding medium, or the humidity is controlled at 75%-85%; the opening of the feeding container is closed with paper or cloth; the external temperature range of the feeding container is the best, and the humidity is controlled At 85-90%; the cultivation time is 20-25 days; when the density of cyst mites in the breeding container reaches 10-100 heads / g, it can be subpackaged and delivered to the factory, and put into the field or greenhouse for biological control.

Embodiment 2

[0029] A: Mass rearing of cyst mites: mixed feeding of Tyrophagous mite and Trichoseius mite.

[0030] Fully mix Maifu and vermiculite as the culture medium, sterilize under high temperature and high pressure at 100°C, put it into a rearing container after cooling down, the water volume in the rearing container is 15% of the culture medium, and then add tyrophagous mite for cultivation When the density reaches 200-300 heads / gram after 3-7 days, insert the hair seiusi mite, and the feeding ratio (hair seii mites: tyrophagous tyrophagous) is between 1:25 and 1:35; after the hair seii mites are inserted, Immediately seal the breeding container with paper; the entire culture environment is at a temperature of 22-25°C and a humidity of 85-90%; after 20-25 days, when the density of the hair sei mites reaches 30-50 heads / g; carry out sub-packaging Then it can be put into use.

Abstract

The invention discloses a method for mass rearing of sac mites. Sterilized rearing medium is grafted into forage mites for culture; when the forage mites reach 50 to 500 heads per gram, the sac mites are grafted, the adding proportion is between 1 to 5 and 1 to 50, and the humidity of a rearing container is controlled to between 65 and 95 percent; the external temperature range of the rearing container is between 18 and 35 DEG C, and the humidity is controlled to between 60 and 95 percent; when the density of the sac mites in the rearing container reaches 10 to 100 heads per gram, the sac mites can be subpackaged and leave factory for control application; when pests appear and the density is lower than 2 heads per leaf, the sac mites can be subpackaged by a mesh bag or a cloth bag and then are arranged in a control area or are directly sprayed on crops, and the release proportion of the sac mites to the pests is between 1 to 15 and 1 to 100. The method can reduce the using times of pesticide, and solve the problems of pest resurgence and residue aggravation and so on caused by using the pesticide.

Description

technical field [0001] The invention relates to a large-scale feeding method of Ascidae in the technical field of biological control and the application of Ascidae mites to the field of crop pest control, in particular to a new method for biological control of greenhouse pests. technical background [0002] The predatory mite natural enemies developed at home and abroad are mainly concentrated in Phytoseiidae (Phytoseiidae) and a few species of Laelapidae (Laelapidae), and there are mature precedents for the large-scale breeding and application of these species, such as the use of Cucumber Neoseiulus (Neoseiulus cucumeris, synonym: Cucumber Amblyseius), Chilean Phytoseiulus persimilis (Phytoseiulus persimilis), California Neoseiulus (Neoseiulus californicus), etc. to prevent and control spider mites and thrips, using Hypoaspis aculeifer and soldiers Shield mites (H.miles) control thrips (pseudopupal stage), fungus mosquitoes and root mites, while research on cyst mites (Asci...
