Embodiment 1

[0043] An artificial feed for Spodoptera frugiperda larvae consists of the following raw materials in parts by mass:

[0044] 250 parts of corn flour, 100 parts of soybean flour, 20 parts of yeast powder, 15 parts of milk powder, 10 parts of multivitamins, 7 parts of ascorbic acid; 4 parts of methyl paraben, 3 parts of sorbic acid, 20 parts of agar powder, 1800 parts of bacteria water.

[0045] The preparation method of the artificial feed of Spodoptera frugiperda larvae of above-mentioned embodiment 1 comprises the steps:

[0046] (1) Sterilize the corn flour, soybean flour, and yeast powder at 120°C for 30 minutes, and weigh the corresponding corn flour, soybean flour, milk powder, yeast powder, multivitamins, and pears according to the formula components and dosage. Acid, ascorbic acid, methyl p-hydroxybenzoate, measure 1200mL sterilized distilled water with a graduated cylinder and pour it into a blender, add the dry matter amount and stir evenly in the blender to obtain co...

Embodiment 2

[0056] The difference from Example 1 is:

[0057] The artificial feed for Spodoptera frugiperda larvae consists of the following raw materials in parts by mass:

[0058] 200 parts of corn flour, 80 parts of soybean flour, 10 parts of yeast powder, 10 parts of milk powder, 5 parts of multivitamins, 6 parts of ascorbic acid; 2 parts of methyl paraben, 2 parts of sorbic acid, 10 parts of agar powder, 1500 parts of bacteria water.

Embodiment 3

[0060] The difference from Example 1 is:

[0061] The artificial feed for Spodoptera frugiperda larvae consists of the following raw materials in parts by mass:

[0062] 300 parts of corn flour, 120 parts of soybean powder, 30 parts of yeast powder, 20 parts of milk powder, 15 parts of multivitamins, 9 parts of ascorbic acid; 6 parts of methyl paraben, 5 parts of sorbic acid, 30 parts of agar powder, 2000 parts of bacteria water.

[0063] In order to illustrate the remarkable effect of the artificial feed for Spodoptera frugiperda larvae of the present invention, the formula of the embodiment of the present invention 1 and other three kinds of formulas, the artificial feed of formula 1,2,3 raise the development index and adult reproduction of Spodoptera frugiperda larvae The ability is compared, wherein, each group allocation ratio of each formula is shown in Table 1.

Abstract

The invention discloses artificial feed for Spodoptera frugiperda larvae and a preparation method and application thereof. The artificial feed for Spodoptera frugiperda larvae is made from, by weight,200-300 parts of corn meal, 80-120 parts of soybean meal, 10-30 parts of yeast powder, 10-20 parts of milk powder, 5-15 parts of vitamin complex, 6-9 parts of ascorbic acid, 2-6 parts of methyl 4-hydroxybenzoate, 2-5 parts of sorbic acid, 10-30 parts of agar powder, and 1500-2000 parts of sterile water. The invention also provides a method of feeding with the artificial feed. The artificial feedfor Spodoptera frugiperda larvae and the preparation method and application thereof have the advantages that materials are easy to attain, the cost is low, preparation is convenient, storage time is long, nutrition is complete, feeding effect is good, the artificial feed is very practical, and large-scale feeding of Spodoptera frugiperda larvae is benefited.

Description

technical field [0001] The technical field of Spodoptera frugiperda of the present invention specifically relates to an artificial feed for Spodoptera frugiperda larvae, its preparation method and application. Background technique [0002] Fall armyworm, also known as fall armyworm, is called Fall armyworm in English and Fall armyworm in Latin. Spodoptera frugiperda (Smith), belonging to the order Lepidoptera and the family Noctuidae, is an omnivorous pest native to tropical and subtropical regions of America. Fall armyworm has a wide range of hosts, harming more than 80 species of corn, alfalfa, barley, buckwheat, cotton, oats, millet, rice, peanuts, ryegrass, sorghum, sugar beets, sudan grass, soybeans, tobacco, tomatoes, potatoes, onions, wheat, etc. plant. Spodoptera frugiperda has strong fecundity, and one female moth lays an average of 1,000 to 2,000 eggs. After hatching, young larvae usually feed on the mesophyll tissue of corn leaves and form a translucent film a...
