Embodiment Construction

[0025] Prepare according to the table:

[0026]

[0027]

[0028] Among them, malt powder and cabbage powder are ground to 100 mesh after drying fresh malt or cabbage leaves.

[0029] The preparation method of the feed of semi-artificial culture diamondback moth, is the following steps:

[0030] (1) Weigh the ingredients according to the above formula, put them into three containers according to the ingredients of mixture A, mixture B, and mixture C, and mix the ingredients fully to form mixture A, mixture B, and mixture C;

[0031] (2) Take about five-sixths of the total amount of distilled water and agar powder into a stainless steel container, heat not higher than 90°C, and stir well until completely melted into agar liquid;

[0032] (3) Pour the mixture A into the prepared agar liquid and stir it for 30 seconds until it is uniform; then add the mixture B and stir it for 30 seconds until it is uniform, add the remaining distilled water, and when the temperature drops...

Abstract

The invention relates to a half artificially fed cabbage moth feed and a preparation method thereof. The feed is prepared by mixtures A, B and C, agar and distilled water, wherein the mixture A comprises casein, sucrose, malt meal and wild cabbage powder; the mixture B comprises cellulose, para hydroxybenzoic acid, potassium sorbate and Watkins salt; the mixture C comprises vitamin C, streptomycin sulphate, propyl gallate, vitamin B complex, edible vegetable oil, potassium hydroxide and formalin. The preparation method comprises the following steps: components of the mixture A, B and C are respectively put into a container; 5 / 6 of the distilled water and the agar powder are added into the container for heating and stirring to thawing; the mixture A is poured into the agar liquid and stirred until uniformity; the mixture B is added and stirred until uniformity; the rest distilled water is added, and the mixture C is added when the temperature is decreased to 70 DEG C, and then stirred until uniformity; the obtained product is filled into moth feeding cups; after the surface moisture is dried, the cups are put into a refrigerator for storage. The preparation method and the feed of the invention are scientific, simple, and easy to standardize propagation the cabbage moth indoors with large scale; the cabbage moth fed with the feed has high larva survival rate, orderly development and sound growth; and the descendants of the cabbage moth have high hatching rate.

Description

technical field [0001] The invention relates to a feed for artificially breeding insects, in particular to a feed for semi-artificially breeding diamondback moth and a preparation method thereof. Background technique [0002] It has been 250 years since the diamondback moth Plutella xylostella (Linnaeus 1758) was officially named. [0003] At present, diamondback moth is an important pest of cruciferous vegetables distributed worldwide. According to data reports in the 1990s, the annual cost of controlling diamondback moth in the world is 1 billion U.S. dollars, and the United States alone costs 100 million U.S. dollars every year. [0004] Plutella xylostella has biological and ecological characteristics such as strong fecundity, short life cycle, alternation of generations and strong adaptability, and its resistance to pesticides develops rapidly and has strong resistance, which makes it difficult to control chemical pesticides. Among them, the concentration of pesticides...
