Method for massively and rapidly propagating fruit flies and obtaining larvae

Abstract

The invention relates to a method for massively and rapidly propagating fruit flies and obtaining larvae. The method comprises the following steps that a cylindrical and transparent culture tube is adopted as a culture container, small ventilation holes are formed in a tube cover, the culture tube are cleaned and aired, the culture tube is filled with fruit fly feed, male fruit flies and female fruit flies are added according to the quantity ratio of (1-3) to 1, culturing is carried out for 12 hours, and eggs are collected; another new culture tube filled with fruit fly feed is buckled on the culture tube with the eggs, after all fruit flies climbs to the new culture tube, the culture tube is taken down, the new culture tube is covered with a cover, then the eggs are continuously cultured and collected, the old culture tube filled with the eggs is covered with a cover, then incubation is carried out, and after 3-4 days, the fruit fly feed in the culture tube is transferred into a wide-mouth container; and the container is placed in a water bath, larvae on the surface of the food are scraped, the larvae are cleaned and sieved, and moisture on the surfaces of the larvae is removed. By means of the method, a large number of clean and high-vigor larvae can be obtained in a short time, the previous fruit fly breeding time is greatly shortened, and the fruit fly breeding cost is reduced.

Description

technical field [0001] The invention relates to a method for multiplying small insects in large quantities, in particular to a method for rapidly multiplying fruit flies in large quantities and obtaining larvae. Background technique [0002] Drosophila is a Diptera insect that widely exists in temperate and tropical climate zones around the world. It is often found in human residences, garbage dumps and the surface of rotten fruits. Drosophila is a saprophytic organism that eats yeast. More than 1,000 species of fruit flies have been discovered so far. The life cycle of Drosophila includes four stages: egg, larva, pupa, and adult. The life cycle is short, and it only takes about 10 days to develop from egg to adult fly at a suitable temperature. [0003] Drosophila larvae have the characteristics of high protein and high fat, and are rich in mineral elements, vitamins, and chitin. They can be used to extract chitosan, and can even be developed into an edible insect for the...

Problems solved by technology

Drosophila is small in body and strong in fecundity, but it has strong flying ability and is not easy to catch. In addition, its larvae live in the food and only gradually move out of the food when they pupate. and feed industry development
