Bean pod borer artificial feed and preparation method thereof

Abstract

The invention discloses bean pod borer artificial feed and a preparation method thereof. The bean pod borer artificial feed comprises, by weight, 62.5-70% of water, 2.5-3.0% of agar, 15.0-20.0% of cooked soybean meal, 4.0-6.0% of cooked wheat embryo powder, 1.0-2.0% of cane sugar, 1.0-1.5% of yeast powder and 3.0-5.0% of auxiliary materials. The auxiliary materials comprise ascorbic acid, choline chloride, methyl parahydroxybenzoate, potassium sorbate, formaldehyde, salt and vitamin complex. The bean pod borer artificial feed is simple in formula, low in price and affordable, raw materials are all common substances and are easy to obtain, a problem of shortage of natural hosts such as cowpea and hyacinth bean limited by seasons is solved, and massive and subculture feeding of indoor bean pod borer standard worm source is achieved.

Description

technical field [0001] The invention relates to an artificial feed for insects and a preparation method thereof, in particular to an artificial feed for the bean borer and a preparation method thereof. Background technique [0002] The bean borer, Maruca testulalis (Geyer), belongs to the order Lepidoptera and belongs to the Mothidae family. It is commonly known as the cowpea borer and the cowpea borer, and is an important borer pest on legume vegetables worldwide (Singh et al., 1978; Ke Lidao et al., 1985). It is widely distributed in my country, from Jilin, Inner Mongolia to southern provinces, Hong Kong, Taiwan and other places (Ke Lidao et al., 1985). Since the 21st century, the occurrence of this insect has been increasing year by year, and the area of ​​occurrence is large, the range is wide, and the damage is serious. In general, the damage rate of cowpea pods can reach 20% to 35%, and in serious cases it can reach 55% to 90%. Due to the boring habit of bean borer l...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the defects that the egg hatching rate and the survival rate of newly hatched larvae are not high, the nutrition of the artificial feed is unbalanced, and the feed components are difficult to obtain in the existing bean moth breeding process, and to provide a kind of composition relatively simple, raw material The artificial diet of the bean borer, which is easy to obtain and is suitable for establishing the experimental population of the bean borer, and its preparation method, so as to realize the subculture of the test insect in the room
