Technical Field

The invention relates to the technical field of predatory mite collection, in particular to a collection device and a collection method for phytoseiid mites.

Background

Tetranychus is the dominant harmful mite which is commonly generated and seriously harmful on agricultural and forestry crops such as fruits, vegetables and the like, and at present, chemical control is always the main measure for controlling tetranychus at home and abroad. Because the pesticide is unreasonably used for a long time, the natural enemies are killed and the ecological balance is destroyed, the spider mites have serious drug resistance to various pesticides, the use concentration of the pesticide or the use times of the pesticide has to be increased in the production, the prevention and treatment cost is greatly increased, and the serious environmental pollution is caused. Therefore, with the long-term and large-scale use of chemical pesticides, the problem of pest mites on agricultural and forestry crops becomes more and more serious.

In recent years, the biological control research on spider mites is increasingly paid attention, and the 'mite control by mites' becomes the most effective measure in biological control of harmful mites, particularly the phytoseiid mites Chile, which are the dominant natural enemies of spider mites. The predatory mites have the advantages of strong adaptability, large predation amount, strong fecundity, agility in action, strong diffusion capacity, good harm control effect, no harm to people and environment, commercial availability and the like, are successively introduced by many countries, are subjected to commercial production, and are primarily applied to agricultural production.

In order to meet the application requirements, researchers are constantly exploring the large-scale production process of phytoseiid persimmons. Phytoseilus persimilis is a special predator of spider mite pest mites, needs to be fed by spider mites, and is complex in scale production. The large-scale production of phytoseiid persimmons is composed of a series of key links, and mainly comprises a series of technical links such as production of host plants of the tetranychus persimmons, mass propagation of the tetranychus persimmons serving as foodstuff, feeding of the phytoseiid persimmons, separation and collection of the phytoseiid persimmons, packaging and storage, and logistics transportation. Wherein the separation and collection of phytoseiid persimmons is a key link for obtaining pure phytoseiid persimmons. However, most of the conventional methods for separating and collecting predatory mites employ methods such as manual brushing, dry ice stunning, blowing, an insect sucker, and passive diffusion in a collection frame separately fixed on a planting bed. Although the methods can obtain relatively pure predatory mites, the methods either need to cut and collect the plants, so that the plants are rapidly necrotic and withered to cause the death of harmful mites, thereby reducing the food supply time of the predatory mites, causing a large amount of predatory mite eggs, young mites and mite which cannot develop into adult mites, and reducing the production efficiency; or the operation method is complicated, the occupied space is large, and the centralized collection cannot be realized. Meanwhile, the operation method has the advantages of high cost, serious escape, high death rate, low collection efficiency and poor collection effect, and is not suitable for industrial production. Therefore, there is a need for a collection method that is easy to handle and has a higher collection efficiency.

Therefore, how to provide a collection device and a collection method convenient for collecting phytoseiid persicae is a problem that needs to be solved urgently by those skilled in the art.
