Method for breeding common cheyletid mites by utilizing dermatophagoides farinae

Abstract

The invention discloses a method for breeding common cheyletid mites by utilizing dermatophagoides farinae. The method comprises the following steps: firstly, sterilizing and drying a breeding container, adding flour, fish bone powder and yeast extract powder in a mass ratio of (5-20):(1-4):(0-3) to serve as breeding foods which reach one fifth to three fifths of the height of the breeding container; then, breeding dermatophagoides farinae int the breeding container to serve as preying mites, introducing common cheyletid mites when the preying mite population density is more than or equal to 100 per gram, and keeping the breeding ratio of preying mites to common cheyletid mites to be (20:1)-(100:1); breeding for 15-60 days to obtain common cheyletid mites completely without preying mites or separating the common cheyletid mites in different containers and keeping on breeding until the population density of common cheyletid mites is more than or equal to 80 per gram; and keeping the breeding temperature to be 17-28 DEG C and a relative humidity of 65-85 percent in the steps. The breeding method is simple, efficient and low in cost, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of carnivorous mites, in particular to a method for raising common carnivorous mites by using dust mites. Background technique [0002] Common carnivorous mite ( Cheylteus eruditus Schrank) is a class of free-living mites belonging to the order Eumacarina, the suborder Prostigmata, and the superfamily Carnivora. Common carnivorous mite is the most common species of carnivorous mite in my country. In our living environment, especially in dust samples, the common carnivorous mite is particularly widely distributed. At present, the most in-depth research on allergic diseases caused by mites is dust mite and house dust mite in dust samples. However, there are few studies on common carnivorous mites in the environment. There are currently 91 literature records on Cheyletus spp., accounting for 9% of the literature, of which 89 are related to carnivorous mites, many of which cannot be identified. .

AI Technical Summary

Problems solved by technology

[0004] However, at present, domestic research on the allergen components of common carnivorous mites is basically in a blank stage, and there is no report on the successful artificial breeding of common carnivorous mites in my country. The main reason for this situation is the lack of methods for artificially raising common carnivorous mites.
