Problems solved by technology

[0004] At present, the research on the artificial feed of the cutworm involves 24.0g of whole wheat germ, 28.0g of vitamin-free casein, 28.0g of sucrose, 20.0g of agar, 8.0g of Webster's mixed salt, sorbic acid The formula that 1.6g, Nibelkin (methyl p-hydroxybenzoate) 1.6g, potassium hydroxide (10%) 16ml, ethanol (95%) 15ml, vitamin mixture 26.4ml, water 650.0ml forms raises little cutworm, The cutworm larvae raised with this formula and their developmental duration were 5-10 days longer than those raised with fresh plants, and other indicators were not significantly different from those of the control, but the article did not mention indicators such as larval survival rate and egg hatching rate.
The existing artificial feed still has certain deficiencies in the survival rate of larvae and the antiseptic effect of the feed. The survival rate of the larvae fails to reach more than 80%, and the feed will appear rotten after being placed under the feeding conditions for 5 days, which affects the life of the larvae. Growth and development; accompanied by the emergence of virus and bacterial contamination, the larvae cannot complete the growth and development process, or produce deformed pupae and eclosion abnormal adults

Description

technical field [0001] The invention relates to an artificial feed for raising insects, more specifically, the present invention relates to an artificial feed for raising small cutworm larvae on a large scale. At the same time, the present invention also relates to a preparation method and application of the artificial feed for the cutworm larvae. Background technique [0002] Agrotis ypsilon (Rottemberg), belonging to Lepidoptera and Noctuidae, is a migratory agricultural pest. Commonly known as ground silkworms and root-cutting insects, they are important underground pests with 106 species of host plants. Not only damage corn, sorghum, millet, millet, wheat, cotton, tobacco, potato, sweet potato, sesame, beans, sunflower, alfalfa, hemp and other crops and various vegetables, but also various fruit trees, forest trees, flowers and other seedlings and a variety of wild weeds. [0003] In recent years, due to the deepening of entomological research and the development of p...
