Housefly larvae culture method

Abstract

The invention belongs to the biological technical field, and specifically relates to a housefly larvae culture method comprising the following steps: using EM bacterium stock solution to process pig dung; mixing pig dung with rice bran; preparing housefly larvae culture medium; luring the housefly larvae to lay eggs on the culture medium; piling for cultivation. The housefly larvae culture method is high in housefly larvae egg hatching rate, fast in fly larva growth speed, the fly is big in size, and an average weight can be increased by 10-20%; the housefly larvae culture medium can be repeatedly used for 4-6 times, thus greatly reducing housefly larvae culture medium consumption, reducing cultivation period, reducing labor intensity and labor amount, and adding benefits; the pig dung is fermented under 32-40 DEG C so as to generate mass beneficial biologically-active substance under beneficial microbe effect, thus killing original disease insects, bacteria and eggs in the pig dung; the generated biologically-active substance can obviously promote fly larva growth and insect resistant ability; the housefly larvae culture method is simple in operation, less in raw material consumption, high in yield, and easy for popularization application.

Description

【Technical field】 [0001] The invention belongs to the field of biotechnology, and in particular relates to a breeding method for fly maggots. 【Background technique】 [0002] The larvae of flies are called fly maggots, which feed on livestock and poultry excrement, grow and reproduce very fast, and can be used to solve the living bait needed by special farmed animals. [0003] At present, in the breeding method of fly maggots, only ordinary small plates and barrels are used for simple and small-scale breeding, which cannot adapt to large-scale production, and the main raw material pig manure does not go through other treatment processes, which contains a large number of diseases and pests, bacteria, insects, etc. Eggs, etc., have a great pathogenic effect on fly maggot larvae, and some also feed on fly maggot larvae, resulting in problems such as low yield, instability, and long cultivation period; and pig manure and the like are mainly used for cultivating fly maggot larvae....

Problems solved by technology

[0003] At present, in the breeding method of fly maggots, only ordinary small trays and barrels are used for simple and small-scale breeding, which cannot adapt to large-scale production, and the main raw material pig manure does not go through other treatment processes, which contains a large number of pests, bacteria, insects, etc. Eggs, etc., have a great pathogenic effect on fly maggot larvae, and some also feed on fly maggot larvae, resulting in problems such as low yield, instability, and long cultivation period; and pig manure etc. are mainly used for cultivating fly maggot larvae. The substrate is generally only used once, and it cannot be reused. On the one hand, it increases the labor and cost of preparing the fly maggot culture substrate, and on the other hand, it also causes great waste.
