Embodiment 1

[0021] A method for rapidly multiplying fruit flies in large quantities and obtaining larvae, comprising the steps of:

[0022] (1) Use a cylindrical culture tube as a culture container. The inner diameter of the culture tube is 5cm, and the height is 7cm. The culture tube is made of transparent plastic material, and there are some small holes for ventilation on the tube cover. Clean the culture tube and dry it. ,spare;

[0023] (2) prepare the fruit fly feed, the fruit fly feed includes the following raw materials: 2L water, 60g brown sugar, 14.5g white sugar, 100g non-defatted corn flour, 49g live yeast powder, 16g agar, propionic acid 8ml, paraben solution 35ml, wherein , the paraben solution is formulated according to the ratio of dissolving 1g methyl paraben in 10ml 95v% ethanol solution;

[0024] Drosophila feed preparation method: take 1L of water, add 16g of agar powder, heat and boil to obtain agar liquid; take another 800ml of water and pour it into a 1L beaker, put...

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...
