Technical Field

The invention relates to the technical field of insect feeding, in particular to an artificial feed formula for scale feeding of myxozoa.

Background

Armyworm, also known as secatella vulgaris and armyworm, commonly known as confetti insect and mairei silkworm, is a parasitic, migratory and intermittent explosive pest mainly made of grain crops such as wheat, corn, sorghum, rice and the like and pasture. Can harm more than 16 kinds of 104 plants in 16 families, especially the plants which like to eat gramineae. However, the armyworm can be used for scale feeding of predatory natural enemies besides injuring crops, eggs or low-age larvae of the armyworm can be used for feeding small predatory stinkbugs such as natural enemy insect orius dongypti, and high-age larvae or pupae can be used for feeding large predatory stinkbugs such as arma bugs.

Aiming at a series of problems of high larva mortality rate, high malformed pupa rate, low egg laying amount and the like of the mythimna separata fed by the feed prepared by the previously published artificial feed formula and the purchased artificial feed product, the artificial feed for the new mythimna separata is created by researching and improving the types and the proportions of the main nutrient components. In the prior inventions or documents, the myxobolus feed is prepared only by using yeast powder or yeast extract powder as a main component, and certain problems are found in experiments. The death rate of the larvae of the feed prepared by only adding the yeast powder is obviously high, and the pupation distortion rate of the larvae of the feed prepared by only adding the yeast extract powder is obviously higher.

In conclusion, the invention has the advantages that the larva mortality rate and the pupation deformity rate are obviously reduced after the seed components are simultaneously added according to the proportion of 1: 1. Through further experiments, the artificial feed prepared according to the ratio of the yeast particles to the yeast extract powder = 4: 1 is found to achieve the lowest reduction in the death rate and pupation aberration rate of larvae, and has obvious increase in the eclosion rate of adults and the egg laying amount of adults.
