Problems solved by technology

[0003] However, the existing artificial diet for armyworm has complex ingredients in terms of formula, and the preparation method and process are relatively cumbersome.
At the same time, many patented formulas tend to reduce the weight of armyworm pupae (less than 0.3g), significantly prolong the pupal life, and significantly reduce the eclosion rate and other population degradation phenomena after continuous feeding for multiple generations.
At the same time, many patents focus on feeding young larvae with natural feed such as corn leaves, while artificial feed is used after the 4th instar. The operation process is many and cumbersome, and the feeding cost is also higher.
In the process of preparing artificial feed, more patents tend to use measures such as cooking with agitator while stirring. When the demand for a feed is large, it is time-consuming and labor-intensive.

Abstract

The present invention discloses an armyworm feed and a preparation method thereof, and belongs to the technical field of animal feeds. The disclosed armyworm feed comprises grass powder, wheat bran, wheat germ, agar, beer yeast, white sugar, potassium sorbate, sodium methylparaben and vitamin C. The disclosed armyworm feed can shorten duration of armyworms, increases the number of annual successive feeding generations, improves an egg production amount, increases a hatching rate, increases an emergence rate and can reduce costs on the whole. The preparation method of the armyworm feed is simple, convenient, time-saving and effort-saving and low in prices.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to an armyworm feed and a preparation method thereof. Background technique [0002] Armyworm is a pest with a very wide range of hosts. Therefore, armyworm is often used as an alternative host for large-scale reproduction of important parasitic natural enemies such as parasitic wasps and parasitic flies. And because armyworm is easy to be reared, it can also be used as the object of safety evaluation of genetically modified organisms and the screening, determination and resistance mechanism of biological pesticides. Therefore, researchers have conducted a lot of research on the artificial propagation of armyworm. In the prior art, corn plants are used as a place and feed for armyworms to lay eggs and larvae. At present, corn leaf powder is mainly used as the main raw material to match some medicines and food materials as artificial feed for armyworm larvae. [0003] However, th...
