Problems solved by technology

This breeding method has great limitations. First, because of the variety and size of the potato pieces, indoor air humidity, temperature, light and other reasons, it is difficult to cultivate a large number of well-developed sweet potato weevils that can be planned for production; secondly, in spring and In summer, the supply of sweet potatoes in the north is relatively short, and the storage and preservation of sweet potatoes requires a lot of cost. The transportation of sweet potatoes in the south is easy to carry the eggs and larvae of the sweet potato weevil. There is no way to replace artificial feed. For example, in the RNAi treatment experiment of the feeding method, it is necessary to add dsRNA to the artificial feed to feed the sweet potato weevils that have been eclosion for 3 days. It is difficult to achieve uniform growth of weevils. The differentiation of weevils on the surface of sweet potatoes and inside sweet potato blocks is very different. It is impossible to determine which ones are the same batch of weevils that have been eclosion for the same number of days. Therefore, it is urgent to develop high-efficiency artificial feed

Abstract

The invention discloses an artificial feed for cylas formicarius. The artificial feed comprises the following components in parts by weight: 70 to 100 parts of agar powder, 140 to 200 parts of sweet potato powder, 15 to 25 parts of casein, 11 to 20 parts of cellulose, 30 to 50 parts of dextroglucose, 5 to 10 parts of a yeast extract, 1.5 to 3 parts of mixed salt, 8-10 parts of sucrose, 10 to 20 parts of ethanol, 1 to 2 parts of ascorbic acid, 0.05 to 0.2 part of compound vitamin B, 0.05 to 0.1 part of choline chloride, 0.25 to 1 part of inositol, 0.5 to 1 part of stigmasterol, 0.3 to 0.9 partof methyl p-hydroxybenzoate, 0.4 to 1 part of potassium sorbate, 0.1 to 0.4 part of tetracycline and 800 to 1000 parts of water. The raw materials used in the artificial feed are common nutrient substances and are easy to obtain, and the artificial feed is simple to prepare and low in cost, and can meet the nutritional requirements of growth and development of the cylas formicarius in various development stages.

Description

technical field [0001] The invention relates to the technical field of artificial feed, in particular to an artificial feed for the sweet potato weevil and a preparation method thereof. Background technique [0002] Sweet potato weevil (Cylas formicarius) belongs to Coleoptera, Weevil family, mainly distributed in tropical and subtropical regions such as Africa, southeastern Asia, America, etc. Floral plants, mainly harmful to sweet potatoes. Both adults and larvae of the sweet potato weevil can harm sweet potatoes, and the larvae mainly eat potato vines and tubers. The overwintering larvae and adults move to the potato seedlings to feed with the sweet potato seedlings. The larvae eat the vine head, the vine head is swollen after being damaged, and it is easy to break, which hinders the normal growth of the plant. The larvae eat the inside of the potato block and form a curved and irregular tunnel, which is filled with insect feces. Cause disease, make the affected potato...
