Athetis lepigone larva feed and preparation method thereof

Abstract

The invention provides Athetis lepigone larva feed, which is made of, in weight percentage, 1-15% of cornmeal, 2-10% of soybean meal, 1-10% of yeast powder, 0-5% of wheat germ flour, 0-5.0% of casein, 0-5.0% of corn leaf powder, 0.1-2.0% of sorbic acid, 0-1.0% of formaldehyde, 0-2.0% of citric acid, 0-1.0% of vitamin B complex, 0-0.5% of ascorbic acid, 0-0.05% of cholesterol, 0-0.5% of choline chloride, 0.1-5.0% of cane sugar, 0.1-5.0% of agar and the balance of distilled water. The invention further provides a preparation method of the Athetis lepigone larva feed, which includes adding the distilled water to cook the agar and the cane sugar, adding the cornmeal prior to boiling, and adding the sorbic acid and the like after boiled stuff is removed from fire. The Athetis lepigone larva feed is applicable to feeding larvae of Athetis lepigone, survival rate of the larvae and egg laying amount of next-generation adults can be increased, and sufficient insect sources are provided for laboratory study of the Athetis lepigone.

Description

technical field

[0001] The invention relates to the preparation of insect feed, in particular to a feed for larvae of the spodopteryx moth and a preparation method thereof. Background technique

[0002] Athetis lepigone Moschler belongs to Lepidoptera Noctuidae. It is mainly distributed in Japan, Korea, Siberia and Far East in Europe and Asia. It is a new pest after the reform of farming system in my country. Domestically, since the insect was first discovered in 2005 in Hebei Province to injure summer maize seedlings, the area infested by it has gradually expanded, and the degree of damage has become more and more serious, which has seriously threatened the safe production of summer maize in the Huanghuaihai region. The larvae of this insect mainly concentrate on the root base of host crops, bite the young tissues of the root base, or damage the stem at the base of the stem, resulting in the death of seedlings, especially corn seedlings at the 3-5 leaf stage.
