Embodiment 1

[0022] Example 1 Feeding method of spider mites

[0023] Raise spider mites in a breeding room with a temperature of 15°C-45°C and a humidity of 50%-100%. The host plant will be planted first. Within 0.5 to 15 days after the host plant unfolds the first pair of true leaves, there will be spider mites. The original leaves or the combination of plant stems and leaves are inoculated on the new host plant together, the spider mites inoculated are the active mite forms of the spider mites, and the leaves are not cut into small pieces or rarely cut into small pieces, wherein The leaf width of the new host plant should be at least 1cm. If the host plant is kidney bean, it is preferred to inoculate when the average leaf width of the host plant reaches 6cm or more. The average number of spider mites per host plant is more than 5, preferably more than 30. The leaves or stems and leaf composition used for inoculation of new host plants are removed within 0.1 days to 10 days, wherein the top...

Embodiment 2

[0025] Example 2 The first feeding method of predatory mites

[0026] Raise predatory mites in a breeding room with a temperature of 15°C-45°C and a humidity of 50%-100%. The entire breeding room for raising predatory mites is sealed, but can be breathable. In the process of raising predatory mites, there is no need to raise insect cages. .

[0027] In the process of raising predatory mites, the inoculation carrier for predatory mites may be optional. If there is, the inoculation carrier can not only be leaves. If leaves are selected as the carrier, a combination of plant stems and leaves is preferred as the inoculation carrier for predatory mites; When the number of spider mites per plant reaches 100 or more, it will be connected to predatory mites, preferably when the number of spider mites per plant reaches more than 600, it will be connected to predatory mites; the ratio of spider mites to predatory mites is greater than 5:1, preferably greater than 60:1 , Less than 1000:1; th...

Embodiment 3

[0029] Example 3 Continuous feeding method of predatory mites

[0030] After the previous batch of predatory mites is harvested, the new batch of host plants with spider mites and to be inoculated with predatory mites will not continue to use the method of inoculating predatory mites on the host plants to raise predatory mites in large numbers, but in the previous batch. Within 10 days, preferably within 1 day, after the secondary predator mites are harvested, move the host plants to be inoculated into the breeding room where the predatory mites have just been harvested, and place them on the breeding rack, breeding platform, ground, and the remaining predatory mites after the harvest. Host plant planting tools, planting substrates, or other places where you can see predatory mites, remove the host plant planting tools left in the previous batch after 0.1 to 10 days, and then reposition or transfer the remaining host plants. According to the amount of predatory mites on the host ...

Abstract

The invention relates to a novel predatory mite production method. The novel predatory mite production method is characterized by including a spider mite breeding method, first-time breeding and continuous breeding methods for predatory mites, a predatory mite separating collection method, a predatory mite packaging method and a cultivating matrix treatment and reutilization method. The novel predatory mite production method has the advantages that the problem about mass breeding of the predatory mites is solved, the method is time saving, labor saving and simple and convenient to operate, breeding cost can be reduced by at least 10% once again, and a great quantity of predatory mite resources can be provided for biological prevention and control of pests.

Description

Technical field [0001] The invention relates to a new method for producing predatory mites and belongs to the field of biological control of agricultural pests. Background technique [0002] The predatory mites in Phytoseiidae are important natural enemies for the control of spider mites, thrips, whiteflies and other pests. Tetranychus mites are commonly used to feed prey during the breeding process of phytoseiid mites. The Chilean phytoseiid mites, Amblyseius parasiticus and Eusei niseri mentioned in the patent application are reared by spider mites. [0003] The existing method for raising phytoseiid mites can realize a large amount of feeding of predatory mites, but still has the disadvantages of time-consuming, laborious, high cost, and relatively low production per unit area of ​​predatory mites. In order to save working time, reduce manpower, reduce production costs, and increase the production per unit area of ​​predatory mites, it is necessary to explore better ways to rai...
