Artificial feed of proxenus lepigone larva

Abstract

The invention discloses an artificial feed of proxenus lepigone larva. According to part by weight, the feed comprises the following constituents of 200-220 parts of corn starch, 118-125 parts of soybean meal, 40-43 parts of yeast powder, 27-29 parts of sugar, 3.5-4 parts of sorbic acid, 28-30 parts of agar, 40-42 parts of casein, 10-12 parts of composite vitamin, 2-3.5 parts of vitamin C, 0.1-0.2 part of streptomycin sulfate, 2.5-5 parts of methanol, 4-6 parts of alcohol, 1-3 parts of vegetable oil and 1000-1500 parts of sterilized distilled water. The artificial feed of proxenus lepigone larva, disclosed by the invention, is available in raw material and low in cost, is convenient to prepare, can be stored for long time, has comprehensive nutritional ingredient, stable feed effect, highpracticability and obvious economical benefit, and is favorable for raising the proxenus lepigone larva on a large scale.

Description

technical field [0001] The invention relates to an artificial feed for insects, in particular to an artificial feed for the larvae of the sudden pest Spodoptera exigua. Background technique [0002] Two o'clock moth Proxenus lepigone (Moschler), synonym Athetis lepigone , which belongs to Lepidoptera, Noctuidae, and Spodoptera genus, is an important new pest in cornfields after the reform of my country's farming system (no-tillage after wheat harvest and stubble sowing), and the scope of damage is expanding year by year. Spodoptera moths are harmful at the seedling stage, mainly eating the base of corn stems and new growth roots, and at the 2-6 leaf stage of corn, mainly eating the base of stems, forming cavities, causing wilting and death of aboveground heart leaves or plant lodging. The larvae are harmed by transferring plants along the ridge. From June to July, they gnaw on the rind of the young watermelon, preventing them from growing up or causing the invasion of pat...

AI Technical Summary

Problems solved by technology

Adults of Spodoptera spp. are active, and larvae are difficult to find in the field, which makes artificial breeding difficult, and there is no ready-made method for reference. In view of these problems, the large-scale propagation of Spodoptera spp. not only provides test materials for biological toxicity determination, but also To provide an insect source basis for the development of microbial biopesticides, we have invented and researched artificial feed for the larvae of Spodoptera spp.

[0004] Document number is that the document of CN102578432A discloses a kind of artificial feed for the larvae of Spodoptera spp. Weeds are only distributed in a small number of areas in my country, and are subject to seasonal restrictions. They are difficult to obtain in most areas or time, which makes it difficult to raise the larvae of Spodoptera moth, and is not easy to implement; in addition, the plant is often rich in nitrate , the larvae may cause poisoning after ingestion
