Method and device for producing fly larvae

Abstract

The invention relates to the field of breeding, in particular to a method and a device for producing fly larvae. The method comprises the following steps of: taking seeds; treating and discharging materials; treating raw materials for breeding the fly larvae until the water content is 60-200 percent; placing the treated fly larvae into a fly larvae breeding pond with side slope angle of 30-45 degrees; taking skins for breeding the fly larvae, wherein the fly larvae generally move at the part which is 3-5cm way from the lower part of a surface layer of the raw material; after a batch of fly larvae grow to three-four days, taking away the raw materials containing the fly larvae in the area and centrally feeding so as to increase the utilization rate of the fly larvae breeding pond; automatically separating the fly larvae by using the climbing characteristic of the fly larvae; arranging fly larvae climbing grooves in the periphery of the fly larvae breeding pond and arranging four fly larvae collecting buckets at four corners of the grooves; and designing that the fly larvae leave from the fly larvae breeding pond, climb and fall into the fly larvae climbing grooves and then climb along the fly larvae climbing grooves and fall into the fly larvae collecting bucket according to the characteristic that the matured fly larvae leave from the fly larvae breeding pond to find dry places for pupating.

Description

technical field [0001] The invention relates to the field of breeding, in particular to a method and device for producing maggot flies. Background technique [0002] Since the 1980s, my country began to promote the technology of raising flies in cages, but it has not formed a scale so far. Maggot flies can be used as fertilizer. The main reason is that the inbreeding of caged flies leads to a decrease in egg production after half a year of breeding, an increase in sterile lines, and finally the entire army is wiped out. The second is that the caged flies are fed with brown sugar milk powder, and the cost of raising them is high. The third is that the design of the fly maggot pond is unscientific, and the allocation of raw materials is not easy to grasp, resulting in difficulties in separating the fly maggots from the raw materials and low output. [0003] In addition, there are also problems such as inbreeding of caged flies, difficulty in preserving fly species in winter...

AI Technical Summary

Problems solved by technology

The second is that caged flies are fed with brown sugar milk powder, and the cost of feeding is high.

The third is that the design of the fly maggot pond is unscientific, and the allocation of raw materials is not easy to master, resulting in difficulty in separating fly maggots from raw materials and low output.

[0003] In addition, there are still problems such as inbreeding of caged flies, difficulty in preserving fly species in winter, and difficulty in domesticating fly species.
