Embodiment 1

[0018] Embodiment 1 utilizes the method for substituting prey to raise predatory mite:

[0019] Under the condition of a temperature of 20°C-30°C and a humidity of 70%-90%, the method of raising predatory mites with mites in the suborder Acardida, the predatory mites refer to Phytoseiidae and Parasitidae The predatory mites raised on the above-mentioned prey can be used in the families of Acarinae, Lepididae, Cysticacaridae, and Macrocheiridae.

Embodiment 2

[0020] The raising method of embodiment 2 spider mites, thrips

[0021] The method for raising spider mites and thrips at a temperature of 20°C-40°C and a humidity of 75%-90%. The spider mites and thrips can be reared using the following method alone or in a mixed manner. The specific operation is: in the host plant Within 0.5 days to 15 days after unfolding the first pair of true leaves, the leaves with the provenance of spider mites and thrips or the composition of plant stems and leaves are inoculated on the new host plant together, and the spider mites and thrips on the inoculation are In each insect state, the leaves are not cut into small pieces or are rarely cut into small pieces, and the width of the new host plant leaves is at least 1 cm. If the host plant is kidney bean, it is preferred to inoculate when the average width of the host plant leaves reaches more than 6 cm. The amount of spider mites and thrips inserted by each host plant is greater than 5, preferably mo...

Embodiment 3

[0022] The collection method of embodiment 3 spider mites, thrips

[0023] When the feeding amount of spider mites and thrips reaches the harvesting amount, they can be harvested and collected. The collection method is to cut off the host plant with scissors, and then put the plant stems, branches and leaves together into the collection device. Separately cut the leaves of the host plant and put them into the collection device, then seal the collection device as soon as possible, and then place the collection device in a suitable space. After fixing it, it can be used for the collection of spider mites and thrips. The collection operation is weekly Check and collect more than once, preferably more than once a day, until no spider mites and thrips can be collected in the collection tube. The collection tube is a container with a length of less than 1m for collecting spider mites and thrips. The plant stems, branches or leaves in the collecting device can be cleaned up after the...

Abstract

The invention relates to a predacious mite feeding method by utilizing alternative preys, spider mites and thrips. The method is characterized in that in the process of feeding predacious mites through the alternative preys, the spider mites and thrips are added into a predacious mite feeding container once per week, and the spider mites and thrips are pure preys without any mediums and can by used independently or in a mixed manner. By the aid of the method, the large amount feeding problem of the spider mites and thrips can be solved, and the simple collecting method of the spider mites and thrips can be further provided. Even though the method is more complex in operation and higher in cost as compared with those of utilizing the alternative preys for feeding independently, according to the predacious mites produced by the method, the identification of the spider mites and thrips by the predacious mites is benefited, and the product quality of the predacious mites can be improved.

Description

technical field [0001] The invention relates to a method for raising predatory mites by using substitute prey, spider mites and thrips, and belongs to the field of biological control of agricultural pests. Background technique [0002] Predatory mites are important natural enemies for the control of greenhouse pests such as spider mites and thrips. Most of the existing feeding methods for predatory mites use alternative prey. [0003] Although the cost of using alternative prey to raise predatory mites is low, it will lead to changes in the preference of predatory mites and changes in feeding habits, which will affect the predation ability of the entire population of predatory mites. [0004] To maintain the quality of predatory mite products, new methods of rearing predatory mites need to be explored. Contents of the invention [0005] The purpose of the present invention is to provide a method that can more effectively maintain the quality of predatory mite products com...
