Maruca testulalis larva artificial feed and preparation method thereof

Abstract

The invention belongs to the technical field of biological feed, and discloses a Maruca testulalis larva artificial feed and a preparation method thereof. The preparation method includes the steps: placing mung beans and wheat germ powder in an oven at a temperature of 120 DEG C, baking for 8 h, and crushing through a crushing machine; weighing agar, adding 1200 mL of water, and boiling to completely melt the agar; and sequentially adding the mung bean powder, the wheat germ powder, yeast, cane sugar, methyl p-hydroxybenzoate, potassium sorbate, wesson's salt, ascorbic acid, choline chloride and mulvital into the boiled and melted agar water according to the raw materials and proportion, uniformly stirring and mixing, pouring into a clean container, cooling to room temperature, and storingin a refrigerator at 4 DEG C for later use. The Maruca testulalis larva artificial feed provided by the invention is simple in components and easy to prepare, optimizes the preparation steps, can beused for large-scale continuous feeding of Maruca testulalis indoors, and also provides a reference basis for feeding of other lepidoptera larvae.

Description

technical field [0001] The invention belongs to the technical field of biological feed, in particular to an artificial feed for cowpea pod borer larvae and a preparation method thereof. Background technique [0002] Cowpea pod borer Maruca testulalis (Geyer), belonging to Lepidoptera and Mothidae, commonly known as bean borer and cowpea borer, is an important agricultural pest on bean crops. It is widely distributed all over the world, and occurs in most parts of China. [0003] In recent years, with global warming and changes in cultivation patterns and cultivation systems, the population of the cowpea pod borer has increased significantly, mainly caused by larvae boring into bean pods. From north to south in my country, the cowpea pod borer can occur 2-10 generations throughout the year, especially in South China, it can occur throughout the year (Xiao Fen, 2007. Research on the biological characteristics and artificial breeding methods of the bean pod borer. Hunan: Hunan...

AI Technical Summary

Problems solved by technology

At present, there are mainly two methods for raising the cowpea pod borer indoors. One is to use natural hosts such as cowpea (flower) and mung bean to raise them, but the natural hosts have a long growth period and are easy to rot. Jin Jiaxin, 2008); the second is to use artificial feed, and studied the formula of artificial feed for the bean moth. Although this method can solve the problem of insect subculture, the feed preparation method is too complicated and unfavorable to operate, and formaldehyde needs to be added in the feed, which affects insect breeding. Human health (Wang Pan, 2012)

[0005] In summary, the existing problems in the prior art are: although the above two commonly used methods can also solve the problem of some experimental insects to a certain extent, the main problems are (1) the breeding method is relatively complicated and the egg production is low , which is unfavorable for large-scale breeding; (2) The feed preparation process is cumbersome, the feed is perishable, and the feed needs to be replaced frequently

Time-consuming

From the above, it can be seen that the existing methods have different shortcomings, and it is difficult to meet the needs of various types of experiments for insect sources of each age and state.
