Method for breeding fruit flies in large scale and obtaining fruit fly larvae in concentrated mode

Abstract

The invention relates to a method for breeding fruit flies in a large scale and obtaining fruit fly larvae in a concentrated mode. The method includes following steps: (1) pouring breeding fruit flies into a glass cup containing artificial feed, and propagating the breeding fruit flies; (2) pouring the obtained breeding fruit flies after propagation in the step (1) into a plastic insect rearing box containing artificial feed, and breeding the fruit fly larvae; (3) obtaining the fruit fly larvae in the concentrated mode, wherein the artificial feed is prepared through following raw materials: 500-1000ml of water, 30-50g of corn flour, 5-10g of soybean meal, 10-30g of maltose, 5-10g of yeast powder, 5-10g of agar powder and 1-5ml of propionic acid. The method for breeding the fruit flies in the large scale and obtaining the fruit fly larvae in the concentrated mode uses the feed artificially prepared to rapidly, tidily and efficiently breed the fruit flies, collects the larvae in the concentrated mode, reduces large scale breeding cost of the fruit fly larvae, and makes large scale breeding of the fruit fly larvae possible.

Description

technical field [0001] The invention relates to a method for artificial breeding of insects, in particular to a method for large-scale breeding of fruit flies and concentrated acquisition of fruit fly larvae. Background technique [0002] Drosophila generally refers to Drosophilidae (Drosophilidae) insects of the genus Drosophila (Drosophila), about 1000 species, especially Drosophila melanogaster (Drosophila melanogaster) is the most representative because of its wide range of feeding habits, easy cultivation, and short life cycle. It is less than two weeks at room temperature and many other characteristics. As a common model organism, it has been widely used in the research of genetics and developmental biology. [0003] Drosophila has a short life cycle, large reproductive capacity, small larvae, thin and soft body walls, weak resistance, and rich protein content. It is a good alternative host for parasitic natural enemies and predatory natural enemies, but its larvae mat...

Problems solved by technology

[0003] Drosophila has a short life cycle, large reproductive capacity, small larvae, thin and soft body walls, weak resistance, and rich protein content. It is a good alternative host for parasitic natural enemies and predatory natural enemies, but its larvae mature until pupation The period of time is extremely short, and the worms are weak, basically unable to resist any mechanical damage, and the adult worms have a strong ability to disperse, and carry pathogenic bacteria in the natural state, making it difficult to raise and collect larvae individuals of the same age in large quantities, which greatly The application of Drosophila larvae as an alternative host for natural enemy insects is limited, which affects the application of natural enemy breeding of pests
