Semi-artificial feedstuff for sesamie inferens and preparation method of feedstuff

Abstract

The invention relates to semi-artificial feedstuff for sesamie inferens and a preparation method of the feedstuff, belonging to artificial feedstuff for insects and feedstuff preparation technologies. The semi-artificial feedstuff is characterized in that each kilogram of feedstuff contains 21-27 grams of soybean flour, 25-60 grams of water bamboo flour, 18-36 grams of rice stem powder, 22-30 grams of corn flour, 16-22 grams of malt flour, 10-20 grams of rice sprout powder, 35-70 grams of yeast, 10-14 grams of cane sugar, 20-30 grams of casein, 1.5-2.8 grams of vitamin C, 0.05-0.15 gram of cholesterol, 5-8 grams of Wesson salt mixture, 2-4 grams of sorbic acid, 1.5-3.0 grams of chlortetracycline, 12-13 grams of agar, and the balance of distilled water. When the semi-artificial feedstuff is used to breed newly hatched larvae of sesamie inferens, the survival rate of the larvae of 12 days is more than 92%, the proportion of the larvae growing to pupas is more than 85%, and 10 generations of larvae can be continuously raised; during the breeding of each generation of larvae, the feedstuff only needs to be replaced once, thus simplifying the operation; and the raw materials are readily available and low in cost.

Description

technical field [0001] The invention belongs to artificial feed for insects and its preparation technology, in particular to a semi-artificial feed for Sinensis moth and its preparation method. Background technique [0002] Large borer Sesamia inferens (Walker) belongs to Lepidoptera, Noctuidae, and is one of the three major stem borers that damage rice in my country. Since the 1990s, due to the restructuring of rice fields and the improper use of chemical pesticides, the damage of the rice borer has increased in my country, seriously threatening rice production. [0003] Artificial diet is an essential tool in entomological research. A mature artificial feed can not only breed a large number of standardized test insects for various experimental studies, but also provide effective technical means for the bioassay of insecticidal active substances, insect toxicology, and insect nutritional physiology. [0004] The history of research on the artificial diet of the large bo...

AI Technical Summary

Problems solved by technology

[0007] 2. Fresh natural food materials such as fresh wild rice stems are limited by seasons. It is difficult to purchase in off-season and the freshness is poor, and the price is expensive. During the breeding process, wild wild rice stems and others are perishable and deteriorate, which will lead to the infection of pathogenic bacteria by the larvae of the large borer, and are not suitable for continuous and long-term cultivation. feeding of large borer

[0008] 3. The survival rate of the young larvae of the large borer on the artificial diet is often low, and the problem can be solved by raising fresh wild rice stems at the young stage, and then transferring them to the artificial diet after the second age, but the procedure is complicated and urgently needs a Artificial feed suitable for raising larvae of different ages in order to simplify the feeding procedure

[0009] 4. The anti-corrosion effect is not ideal, and the use of preservatives is unreasonable, which needs further optimization

For example, the chloramphenicol used by Liu Zhuorong (2007) has a relatively large side effect on the larvae of the larvae, which is the main reason why the survival rate of the larvae in this feed is only 40.9%.

[0010] 5. There are problems in the feed preparation process, such as high processing temperature, long-term high-temperature treatment of some components that are not resistant to high temperature, etc., which damage the nutritional content and stability of the feed components and affect the feeding effect of the feed
