Culture medium for manually and rapidly feeding Chinese chive maggots and preparation method of culture medium

Abstract

The invention relates to a culture medium for manually and rapidly feeding Chinese chive maggots and a preparation method of the culture medium, belonging to the technical field of feeding of the Chinese chive maggots. The preparation method comprises the steps of heating a beaker containing distilled water on an electric furnace, on which asbestos gauze is spread, to about 30 DEG C, sequentially adding agar powder, carrageenan and guar gum, simultaneously stirring, after the agar powder, carrageenan and guar gum are completely dissolved and boiled, sequentially adding vegetable oil, cane sugar, wheat germs, fresh Chinese chive and yeast powder, re-boiling for 2 minutes, cooling to 60 DEG C below, sequentially adding potassium sorbate, malic acid and propionic acid, uniformly stirring, filling a culture bottle with the measured mixture, and naturally cooling and solidifying, so as to obtain the finished culture medium for feeding the Chinese chive maggots. The culture medium is designed aiming at the feeding of the Chinese chive maggots, a moisture preservation effect is improved, and the manual cost and the workload for exchanging feeds and preserving moisture are greatly reduced; compared with an existing feeding method of the Chinese chive maggots, the culture medium has the advantages that the special culture medium is only used once in the whole growing period of larvae, the labor intensity is low, the moisture preservation effect is good, the nutritive value is high, the growth and propagation speeds are high, etc.

Description

technical field [0001] The invention relates to a culture medium for artificially rapidly raising chive maggots and a preparation method thereof, belonging to the technical field of raising chive maggots. Background technique [0002] The artificial mass propagation technology of the tested insects is one of the important means of pest control and research on their biological characteristics, such as chive maggots. Chive maggots are the larvae of Chive tardiformis, which are unique vegetable pests in my country. They especially like to eat leeks, onions and garlic. The insect is small, reproduces quickly, has serious generation overlap, and damages a wide area. Generally, the yield of leek fields is reduced by 40-60%, and in severe cases, it may even be completely wiped out. For a long time, in order to reduce its harm, vegetable farmers mainly use chemical pesticides to control the larvae, resulting in serious pesticide pollution of leek products. According to a market su...

AI Technical Summary

Problems solved by technology

[0003] At present, the methods commonly used in the artificial breeding of chive maggots include the method of adding filter paper to the culture dish to keep moisture, and changing the fresh leek stem every day; Poor, high frequency of refueling, high labor intensity

Although it overcomes some limitations of adding filter paper to the petri dish, improves the moisturizing effect, and reduces the labor intensity of daily replacement of fresh leek stems, the frequency of replacement of artificial feed is still relatively high.

The whole growth period of leek maggot needs to change the feed or do moisturizing treatment many times, which has a certain labor intensity and reduces the feeding efficiency
