Chrysomyia megacephala culture medium and preparation method thereof and culture method of chrysomyia megacephala

Abstract

The invention relates to the technical field of animal cultivation, in particular to a chrysomyia megacephala culture medium and a preparation method thereof and a culture method of chrysomyia megacephala. The culture medium is prepared from fish meal, milk powder, yeast powder, sodium chloride, agar and water. The culture medium has the advantages that the components are simple, the cost is low,nutrition matching is reasonable, the growth activities of chrysomyia megacephala larvae are observed conveniently, and sampling is convenient; the solid culture medium is adopted to culture the chrysomyia megacephala, and is conductive to the study of the individual differences and population differences of the chrysomyia megacephala; the cultivation process does not produce a foul odor, does notaffect normal life, and can be widely applied to large-scale and small-scale cultivation requirements.

Description

technical field [0001] The invention relates to the technical field of animals, in particular to a culture medium for Chrysocephala botany and a preparation method and a breeding method thereof. Background technique [0002] Chrysomya megacephala (Fabricius) belongs to Diptera, Calligraphidae, and Chrysomya subfamily insects. Scavenging, widely distributed species in China, very common in the Yangtze River Basin. It is widely distributed in Japan, Vietnam, East Asia, and Oceania, and has also been reported in America and Europe. Chrysalis chinensis is one of the first flies to arrive at the corpse to lay eggs, which can provide important clues for inferring the time of death; it is an important mango pollinator in Australia, Taiwan and South China. In addition, Chrysocephala larvae are rich in protein, fat, and chitin, and are a new source of economic products such as fly maggot protein powder, biodiesel and chitosan; at the same time, the dried larvae of Chrysocephala chi...

AI Technical Summary

Problems solved by technology

However, these breeding methods are only for the purpose of raising Chrysocephala chinensis, and do not pay attention to the impact of the breeding process on the physiology and biochemistry of Chrysocephala chinensis. There are usually serious problems such as uncontrollable chemical composition of raw materials, uncontrollable influence of auxiliary materials, water and stirring on fermentation, etc. Therefore, it is difficult to accurately repeat the breeding process, and it cannot be used as a basic culture method for specific research on the physiology and biochemistry of Chrysocephala chinensis.

At the same time, this kind of breeding method uses large pots or large ponds to raise, and it is inconvenient to observe and collect fly maggots during the experiment, especially the collection of young larvae, which are small and easy to be mixed with auxiliary materials, and the cleaning process is cumbersome and time-consuming

[0005] In addition, regardless of small-scale laboratory breeding or large-scale industrial organic waste breeding, the problem that cannot be effectively avoided so far is the stench emitted by the corruption of compost during the cultivation process, which not only interferes with people's normal life, but also produces unpleasant feelings. while polluting the environment
