Problems solved by technology

Although the existing method of using spider mites to raise predatory mites can achieve large-scale feeding of predatory mites, it not only has the defects of time-consuming, laborious, high cost, and relatively low production per unit area of ​​predatory mites, but also the separation, collection and processing of predatory mites Packaging technology is not yet optimal

Embodiment 1

[0022] The raising method of embodiment 1 spider mite

[0023] Raise spider mites in a breeding room with a temperature of 15°C-45°C and a humidity between 50%-100%. The leaves of the source or the composition of the plant stem and leaves are inoculated together on the new host plant, the inoculated spider mites are the various active mite states of the spider mite, and the leaves are not cut into small pieces or rarely cut into small pieces, wherein The width of the leaves of the new host plant is at least 1 cm. If the host plant is kidney bean, it is preferred to inoculate when the average width of the leaves of the host plant reaches more than 6 cm. The average number of spider mites inserted into each host plant is greater than 5, preferably more than 30. The composition of leaves or stems and leaves used for the inoculation of new host plants is removed in the next 0.1 days to 10 days, wherein the terminal buds of the plants are not cut or cut less, preferably only cut 1-...

Embodiment 2

[0025] The first feeding method of embodiment 2 predator mite

[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 feeding predatory mites is sealed, but it can be ventilated. In the process of raising predatory mites, no insect cage is required. .

[0027] In the process of raising the predatory mite, the inoculation carrier of the predatory mite is dispensable, if there is, the inoculation carrier can not only be the leaves, if the leaves are selected as the carrier, the composition of the plant stem and the leaves is preferably used as the inoculation carrier of the predatory mite; When the number of spider mites per plant reaches more than 100, predatory mites are inserted, preferably when the number of spider mites per plant reaches more than 600, predatory mites are inserted; the ratio of spider mites to predatory mites is greater than 5:1, preferably greater than 60:1 , less than 1000...

Embodiment 3

[0029] The continuous rearing method of embodiment 3 predator mite

[0030] After the previous batch of predatory mites were harvested, the new batch of host plants with spider mites and to be inoculated with predatory mites did not continue to use the method of inoculating predatory mites to host plants to raise predatory mites in large quantities, but Within 10 days after the second predatory mite is harvested, preferably within 1 day, the host plant to be inoculated is moved into the rearing room where the predatory mite has just been harvested, placed on a rearing frame, a breeding platform, the ground, and the remaining Host plant planting utensils, planting substrates or other places where predatory mites can be seen, remove the host plant planting utensils left over from the previous batch after 0.1 days to 10 days, and then rearrange or transfer the remaining host plants, According to the amount of predatory mites on the host plant, it is judged whether to harvest dire...

Abstract

The invention related to a predatory mite mass breeding method by breeding spider mites. The predatory mite mass breeding method is characterized by comprising a spider mite breeding method, a predatory mite breeding method integrating the first breeding and the continuous breeding, a separated collecting method for the predatory mites, a packaging method for the predatory mites and a cultivation matrix processing and recycling method. According to the arrangement, multiple processes in the predatory mite breeding are omitted, breeding cost is decreased by 10% or above, predatory mite output reaches 30000 / m<2>, besides, for the first time, inoculation is not required during continuous breeding of the predatory mites, and large-scale breeding is implemented. And meanwhile, the separating, the collecting and the packaging of the predatory mites are realized, and the cultivation matrix is saved.

Description

technical field [0001] The invention relates to a method for mass-producing predatory mites by using spider mites. The predatory mites refer to the predatory mites in the family Phytoseiidae and belong to the field of biological control of agricultural pests. Background technique [0002] Predatory mites in the Phytoseiidae family are important natural enemies for the control of spider mites, thrips, whitefly and other pests. Tetranychus are the common prey for raising phytoseiids. The phytoseiids mentioned in the patent application, A. viridans and E. nissl are raised by using the spider mites. Although the existing method of using spider mites to raise predatory mites can achieve large-scale feeding of predatory mites, it not only has the defects of time-consuming, laborious, high cost, and relatively low production per unit area of ​​predatory mites, but also the separation, collection and processing of predatory mites Packaging technology is not yet an optimal issue. ...
