Problems solved by technology

Domestically, regarding codling moth breeding, Yang Fuyin et al. (2009) studied the effects of different food materials on the growth, development and reproduction of codling moth. Liu Yueying et al. (2012) compared the life tables of codling moth experimental populations at different temperatures, but they Raised with natural food (mainly apples), the indoor population is difficult to maintain due to the limited acquisition and storage of natural food and the disadvantages of easy mold - feeding throughout the year
In addition, Shen Jianru (2011) tried the improved germ apple powder method to feed codling moths, but the addition of apple powder is obviously not convenient for the promotion and application of this feed
It can be seen that there is no feed with simple components and easy preparation in my country to establish a continuous breeding population of codling moth

Embodiment 1

[0017] Preparation of Artificial Feed A for Codling Moth

[0018] Weigh 25g of soybean meal, 50g of whole wheat flour, 5g of sucrose, 10g of yeast powder, 30g of wheat germ, and 7g of agar into a 1000ml beaker, add water to make up to 500ml, stir well, and then sterilize under high pressure (0.1MPa) steam at 121°C for 20min. Cool down to about 60°C, add 3g of ascorbic acid, stir well, then add 1g of sorbic acid (dissolved in 10ml of alcohol) and 1ml of propionic acid, mix well, put it into a fresh-keeping box, and use it after cooling. Among them, sorbic acid and propionic acid are preservatives.

[0019] It should be noted that when preparing a small amount of feed, soybean meal can be used instead of soybean meal. The 0.2% preservative in the experiment did not see the occurrence of mold and other pollution, and its content can be increased or decreased as appropriate depending on the breeding environment.

Embodiment 2

[0021] Preparation of Artificial Diet B for Codling Moth

[0022] Weigh 20g of soybean meal, 40g of whole wheat flour, 10g of sucrose, 25g of yeast powder, 25g of wheat germ, 1g of sour agent, and 7g of agar into a 1000ml beaker. 20min. Cool to about 60°C, add 2g of ascorbic acid, stir well, then add 0.5g of sorbic acid and 0.5g of methylparaben (dissolved in 10ml of alcohol), mix well, put it into a fresh-keeping box, and use it after cooling. Among them, sorbic acid and methylparaben are preservatives.

[0023] The artificial feed of the embodiment is added with a sour agent commonly used in the food industry. The sour agent is citric acid and malic acid in a mass ratio of 1:1, which can enhance the acidity of the feed, promote feeding, improve the antiseptic effect and protect ascorbic acid. Browning has a certain effect of keeping feed fresh.

Embodiment 3

[0025] Preparation of Artificial Diet C for Codling Moth

[0026] Weigh 50g of soybean meal, 30g of whole wheat flour, 10g of sucrose, 15g of yeast powder, 20g of wheat germ, 2.5g of sour agent, and 5g of agar into a 1000ml beaker, add water to make up to 500ml, stir well and then sterilize with high pressure (0.1MPa) steam 121 ℃ 20min. After cooling to about 60°C, add 2g of ascorbic acid, stir well, then add 1g of methylparaben (dissolved in 10ml of alcohol) and 1ml of propionic acid, mix well, put it into a fresh-keeping box, and use it after cooling. Among them, propionic acid and methylparaben are preservatives.

[0027] In this embodiment, the proportion of soybean meal and sour agent is increased, and an attempt is made to save feed cost. This formula is conducive to the direct use of animal feed for mass breeding of codling moths.

Abstract

The invention relates to an artificial feed for codling moths and a preparation method of the artificial feed, and belongs to the technical field of insect feeding, wherein the artificial feed for codling moths is characterized by being prepared from the following components in percent by weight: 2-10 percent of bean pulp, 6-10 percent of whole meal, 1-3 percent of saccharose, 2-5 percent of yeast, 4-8 percent of wheat germ, 1-2 percent of agar, 0-0.5 percent of a sour agent, 68-80 percent of water, 0.3-0.6 percent of ascorbic acid, 0.1-0.5 percent of preservative and 1.5-3 percent of ethyl alcohol. The codling moths fed by using the feed provided by the invention can develop well, and can be continuously fed; an insect source guarantee is provided for indoor research and a technical support is provided for large-scale feeding.

Description

technical field [0001] The invention belongs to the technical field of insect feeding, and relates to an artificial feed for codling moth and a preparation method thereof. Background technique [0002] At present, the insects raised by artificial feed involve Orthoptera, Isoptera, Hemiptera, Homoptera, Coleoptera, Lepidoptera, Hymenoptera, Diptera, Neuroptera and other agricultural and forestry pests and various economical insects. Artificial diets can make insects develop neatly and have consistent physiology, and are widely used in research on nutritional physiology, toxicology, bioassays of insecticidal active substances, and the relationship between insects and plants. In many cases, it is the main way to solve the seasonal feed shortage, such as winter because most of the natural food is not available, only by relying on artificial feed to maintain insect populations. A variety of standardized and high-quality insects raised with artificial diets will play an importan...
