Dichocrocis punctiferalis artificial feed as well as preparation method and application thereof

Abstract

The invention discloses dichocrocis punctiferalis artificial feed and a preparation method thereof, and belongs to the field of insect feed. The artificial feed has the advantages that the feeding effect is good; the indexes such as the survival rate, the single-female egg laying amount and the hatching rate are obviously higher than the feeding effect of the existing artificial feed. Secondly, the artificial feed can meet the nutrition requirements of the dichocrocis punctiferalis three-year-old larvae to pupating stages; the large-scale and long-time transgenerational feeding of the dichocrocis punctiferalis can be realized. The ingredients of the artificial feed are all common ingredients in daily life; the cost is low; the materials can be easily obtained. In addition, the yeast powder, sucrose, vitamin C and composite vitamin B in the artificial feed can provide nutrition for the accelerated growth of the dichocrocis punctiferalis in each growth stage; the pathogenic bacterium infection and death can be reduced; the plant oil can be used for preventing the later stage dry cracking phenomenon in the later stage.

Description

technical field [0001] The invention belongs to the field of insect feed, and in particular relates to an artificial feed for peach moth moth, a preparation method of the artificial feed, and an application of the artificial feed. Background technique [0002] Peach borer (Conogethes punctiferalis), commonly known as peach spot borer, peach heart borer, peach borer, etc., belongs to the genus Conogethes punctiferalis of Lepidoptera, and mainly damages chestnuts, peaches, plums, pears, apples, pomegranates, and plums. , cherry, citrus, loquat, apricot, persimmon, hawthorn, masson pine, fir, sunflower, soybean, corn, cotton and other fruit trees and crops, with miscellaneous feeding habits and a wide range of hosts, it is an important omnivorous and borer Sexual pests (Wang Zhenying et al. Plant Protection, 2006, (2): 67-69). In recent years, due to changes in climate, farming system and cultivation methods, the population of Peach Borer has shown a rapid upward trend. Peach...

Problems solved by technology

[0004] At present, the artificial feed that is used to raise peach borer mainly contains: Honda H etc. (Honda H etc. Appl. Difficult to purchase and difficult to promote and apply

Chinese patent "peach moth moth artificial feed formula and preparation method" (CN103478493A) discloses that it is made of chestnut powder, corn flour, peach powder, soybean powder, brewer's yeast powder, multidimensional glucose, casein, cholesterol, ascorbic acid, erythromycin, agar Powder, methyl paraben, methyl p-hydroxybenzoate and water. The components of the artificial feed have not been autoclaved during the preparation process. During the entire feeding process, the feed needs to be replaced every 3 days to prevent the feed Mold pollutes the larvae, so the raising process is labor-intensive and time-consuming; another Chinese patent "artificial feed for peach moth moth, preparation method and subculture feeding method" (CN104304694A) discloses a mixture of wheat germ powder, soybean meal, corn seedling dry powder, chestnut dry powder, Artificial feed composed of yeast extract, potassium sorbate, ethyl p-hydroxybenzoate, vitamin C, corn germ oil, trehalose, agar powder and water, this artificial feed solves the problems of low survival rate and poor succession of the population, However, subculture rearing is done in finger tubes, and two larvae are placed at most. These two kinds of artificial diets raise a small number of peach moths, which cannot achieve the purpose of mass production of peach moths, and the cost of main materials is high. Not easy to obtain; Xu Lirong (Xu Lirong. Chinese Academy of Agricultural Sciences master's degree thesis 2011) slightly changed the feed formula of the corn borer and used it to raise the peach borer. -54.88 grains, and the feed appeared to be dry and cracked in the later stage of feeding, and the purpose of large-scale feeding could not be achieved

[0005] From the above, it can be seen that the existing artificial feeds for raising the peach borer have different shortcomings, and they cannot realize the large-scale breeding of the peach borer, and it is difficult to meet the requirements of various tests for each stage and each larval instar of the peach borer. source of demand
