Feed for raising chilo venosatus walkers and preparation method of feed

Abstract

The invention discloses a feed for raising chilo venosatus walkers and a preparation method of the feed. The feed is prepared from the following raw materials in parts by weight: 750-770 parts of water, 36-40 parts of yeast extract powder, 28-32 parts of casein, 13-17 parts of agar, 0.4-0.5 part of potassium hydroxide, 3.5-4.0 parts of ascorbic acid, 0.25-0.35 part of multivitamin and minerals tablets, 13-17 parts of cane sugar, 6-8 parts of wheat bran, 8.5-11.5 parts of maize flour, 113-118 parts of sugarcane stem powder and 0-4.4 parts of a preservative. The preparation method comprises the step of uniformly mixing all the raw materials. The feed prepared by the preparation method disclosed by the invention is suitable for feeding the chilo venosatus walkers, the developmental rate, the survival rate, the pupal weight and the pupation rate of a larva can be greatly increased, the developmental physiological status of an insect source are basically consistent, and requirements for nutrient substances of the development of a whole generation or development of generations of the chilo venosatus walkers can also be met.

Description

technical field [0001] The invention relates to the field of feed, in particular to a feed for raising sugarcane barworm and a preparation method thereof. Background technique [0002] Sugarcane bar borer (Chilo sacchariphagus Bjojer) belongs to Lepidoptera moth family insects, is one of the most serious frequent pests on sugarcane, causing great economic losses to my country's sugar industry every year, mainly distributed in Guangdong, Guangxi, Fujian , Sichuan, Yunnan, Jiangxi and Taiwan and other provinces and regions, in addition to harming sugarcane, it can also harm crops such as sorghum and corn. In the integrated control of sugarcane borer, the development of new pesticides, the use of pheromones and transgenic sugarcane play an important role, and the bioassay of such technologies requires a large number of sugarcane borers with the same developmental period to obtain such test insects The only way is large-scale artificial breeding, so it is imperative to study art...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the sugarcane borers are raised indoors using natural host sugarcane plants, which is difficult to carry out large-scale breeding; although some research has been done on the artificial breeding of sugarcane borers at home and abroad, the temperature and humidity related to the breeding of individual sugarcane borers , lighting conditions have been basically determined, but still need to be improved in many aspects

There are few studies on the artificial feed formula and preparation methods of the sugarcane borer. Only in 1996, the research on the semi-pure artificial feed for the sugarcane borer was reported, which used casein, sucrose, yeast extract powder, sugarcane stem powder and sugarcane leaves. Powder, etc. were used as raw materials, heated and dissolved in a beaker to form a semi-pure artificial feed, and the feed was poured into a test tube to cool for later use. Finally, sugarcane borer egg masses were placed in the test tube to raise them. not ideal
