Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiments.

[0019] Plutella xylostella artificial feed mix is ​​shown in Table 1 and Table 2.

[0020] Table 1: Plutella xylostella artificial diet formula 1

[0021]

[0022] Table 2: Plutella xylostella artificial diet formula 2

[0023]

[0024] The feed for artificially cultured Plutella xylostella larvae is prepared according to the following steps: 1) weigh each component according to the formula; 2) then take three-fifths of the total amount of distilled water and add cabbage powder, yeast powder, and corn flour to a stainless steel container, add Bring to a boil at 100°C, stir evenly to obtain a mixed solution; 3) Take two-fifths of the total amount of distilled water, agar powder, and sorbic acid, add them to a stainless steel container, heat to 100°C, boil, stir evenly to obtain another mixed solution ; 4) Then add the mixed solution obtained in steps 2) and 3) into v...

Abstract

The invention relates to artificial feed for larvae of plutella xylostella and a preparation method thereof. The artificial feed is prepared from various components in certain proportion. The artificial feed for larvae of plutella xylostella comprises the following components in percentage by weight: 6-8% of cabbage powder, 3-5% of yeast powder, 6-8% of corn meal, 0.3-0.5% of vitamin C, 1-3% of agar powder, 0.1-0.3% of sorbic acid and the balance of distilled water. Through the invention, necessary conditions are provided for large-scale feeding of the larvae of plutella xylostella, technicalguarantee is provided for the accuracy of the detection result of the effect of pesticide, the pollution caused by feeding with natural feed is reduced, energy consumption for disinfecting and sterilizing an insectary is reduced; and controllable sterile feed is provided for the production of plutella xylostella virus.

Description

technical field [0001] The invention relates to an artificial feed for insects, in particular to an artificial feed for diamondback moth larvae and a preparation method thereof. Background technique [0002] Plutella xylostella is one of the important pests of cruciferous vegetables in the world. According to data reports in the 1990s, the annual cost of controlling diamondback moth in the world is as high as 1 billion U.S. dollars, and the United States alone costs 100 million U.S. dollars per year. [0003] 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 used and the frequency of application are constantly increasing, forming a vicious cycle of "pesticide-resistance-pesticide" with a he...
