Artificial feed of sesamia inferens walker as well as preparation method and feeding method thereof

Abstract

The invention relates to an artificial feed of sesamia inferens walker as well as a preparation method and a feeding method thereof, belonging to the technical field of insect feeding. The artificial feed comprises soybean meal, corn meal, wheat germ, yeast powder, casein, cane sugar, honey, fresh wild rice shoots or fresh rice stems, ascorbic acid, cholesterol, choline chloride, Fiske salt, vitamin B complex, vitamin E, sorbic acid, methyl parahydroxybenzoats, 40 percent formaldehyde, 98.18 percent rice ketone, agal-agal and water. A long-term and successive feeding method of the sesamia inferens walker is carried out by adopting a wild rice shoots (young larva) and artificial feed (old larva until pupation). The fed larva of the sesamia inferens walker have development period of 24.8 days, larva survival rate of 76.6 percent, percentage of pupation of 87.7 percent, eclosion rate of 91.3 percent, egg laying amount of 101.9 for single adult and egg hatching rate of 88.8 percent. The invention has the advantages of low cost, practicability, simple preparation, and the like, and is suitable for massive, long-term and successive feeding of standard test sesamia inferens walkers.

Description

technical field [0001] The invention relates to insect feed and feeding technology, in particular to an artificial feed for Sinensis moth, its preparation method and a specific feeding method using the feed. technical background [0002] Sesamia inferens (walker) is one of the important pests of rice, and also an important pest of economic crops such as wild rice stem, corn, water chestnut and sugar cane, and it is distributed in both the north and south rice regions of my country. Since the 1990s, with the warming of the global climate and the changes in rice cultivation systems, varieties and cultivation systems, the population of Sinella borer in some areas has shown an obvious upward trend, and the damage has increased year by year. The annual occurrence area exceeds 25.05 million mu. The current rice production poses a serious threat (Fu Qiang and Huang Shiwen, 2005). Another study found that, as an effective agent for the control of Chilo borer, Fipronil, which is an ...

Problems solved by technology

[0004] Therefore, to sum up, the above research has indeed solved the difficult problem of the standard insect source demand of the large borer in the research work to a certain extent, but it still cannot realize the high-quality, large-scale, annual, and subculture breeding of the test insects.

At present, the main problems in artificial breeding are: (1) The ingredients of the feed are too single, which cannot meet the nutrients required for the development of the entire generation of C.

Although some feed formulas are very complicated, and the preparation process is also very cumbersome, they have not found the key nutritional factors suitable for the growth, development and reproduction of the large borer, so that the feeding effect of the large borer is still very low; If the above-mentioned feed is used to feed the large borer, the survival rate of the first-generation larvae is basically maintained above 60%, but after the third generation, the survival rate drops significantly, and some are only 3%-40%.

One of the common points of the above feeds is that the survival rate of eggs is low. The survival rate of the first generation of reared eggs is only about 60%. With the increase of feeding generations, the survival rate is even lower.
