Spawning inducer for housefly larvae and application thereof

Abstract

The invention belongs to the technical field of housefly larva breeding, and discloses a spawning inducer for housefly larvae. The spawning inducer comprises base materials and humectants, wherein themass part ratio of the base materials to the humectants is (1-1.5): 1; the base materials comprise milk powder, brown sugar, wheat bran and water; and the humectants comprise saw dust and ammonia water. Meanwhile, the invention also provides a method for inducing spawning of the housefly larvae. The method comprises the following steps: fully and uniformly stirring the base materials of the spawning inducer, placing mixed base materials onto the bottom layer of the seed receiving box of the housefly larvae, fully and uniformly stirring the humectants, placing mixed humectants onto the mixed base materials, taking out the seed receiving box after 24 hours, placing a new seed receiving box at same time, and circularly collecting eggs of the housefly larvae. By adoption of the spawning inducer of the housefly larvae provided by the invention, houseflies can be induced to continuously spawn on the spawning inducer for 18-24 hours; the phenomenon that the houseflies spawn in other places within the first 12 hours is avoided; and the phenomenon of stacking death is greatly avoided.

Description

technical field [0001] The invention belongs to the technical field of fly maggot cultivation, and in particular relates to a fly maggot oviposition inducer and application thereof. Background technique [0002] Maggots are the larvae of flies. It is mainly born in human and animal manure piles, garbage, and decaying substances, and feeds on feces and decaying substances, and some lives in decaying animal corpses. Pupate under the soil surface and survive the winter as pupae. The depth of overwintering pupae in the soil can reach about 10 cm. [0003] At present, fly maggots can be used as an efficient protein feed for insects, and the demand in aquatic products is very strong, but the breeding of fly maggots is in its infancy, and many traditional technologies are not efficient, immature and inconvenient. The culture of fly maggots is generally high-density culture, and the important link is the induction of fly maggots to lay eggs, so as to obtain a large number of fly m...

AI Technical Summary

Problems solved by technology

According to prior art records, the cultivation of fly maggots generally adopts the material of substrate, feed and the effect of increasing egg collection as the egg collection material, wherein the material for egg collection can be animal minced meat, animal blood clots and fly maggot residues, but blood clots, etc. are used. The quality and sanitation of the source of slaughtering waste cannot be strictly guaranteed, which has a great impact on the efficiency of fly maggot breeding; at the same time, wheat bran, ammonia water or poultry feed are also used as egg-collecting inducers in the prior art, but the induction time is also limited. It is far from enough to support the demand for housefly larvae in actual production

At the same time, the traditional egg-collecting inducer is not attractive enough to houseflies, causing housefly larvae to lay seeds everywhere, destroying the breeding environment, and waste eggs, which reduces economic benefits. The traditional way of collecting eggs is in Under high-density breeding, it is easy to stack to death
