Semi-artificial cultivated diamondback moth feed and method of preparing the same

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...

Problems solved by technology

Plutella xylostella larvae typically develop slowly, taking up to a month to develop, with irregular developmental periods, and difficulty in normal pupation and eclosion when reared using recipes provided elsewhere
