Problems solved by technology

However, limited by the season and the growth cycle of the host plant, especially when the larvae of the fall armyworm are at a higher density, the larvae often kill each other, or the larvae bite the pupa. Therefore, there is an urgent need for a fresh food that can be obtained year-round. Feed, and optimize the feeding method and process to raise the larvae of Spodoptera frugiperda in groups, realize the orderly and subculture feeding of each worm state of Spodoptera frugiperda. Scientific research and the expansion of natural enemy parasitoids provide a large number of physiologically uniform insect sources

Embodiment 1

[0040] Example 1 (wheat seeds)

[0041] The present invention is a method for raising Spodoptera frugiperda in groups by utilizing wheat hydroponic seedling trays, comprising the following steps:

[0042] (1) Preparation of wheat hydroponic seedling tray:

[0043] a. Weigh 100g of wheat seeds, soak them in tap water for 12 hours after washing, and lay them flat in a plastic tray with a net. The height of the mesh is not submerged, the water level under the tray is not less than 4cm, and it is placed at room temperature for cultivation;

[0044] b. After 9-12 days, when the green wheat seedlings grow to 15-20cm, take out the wheat seedling tray and drain it, prepare a sterilized towel, soak it in water and wring it dry, lay it flat on the table, and place the wheat seedling tray on the towel Loaded and wrapped, ready to use;

[0045] c. Take three wheat seedling trays, fix a bottom hydroponic seedling tray, and place the side hydroponic trays on the left and right edges of t...

Embodiment 2

[0056] Example 2 (barley seed)

[0057] The present invention is a method for artificially raising Spodoptera frugiperda larvae with a hydroponic seedling tray of barley seeds, comprising the following steps:

[0058] (1) Preparation of barley hydroponic seedling tray:

[0059] a. Weigh 80g of barley seeds, soak them in tap water for 12 hours after washing, and lay them flat in a plastic tray with a net. The height of the mesh is not submerged, the water level under the tray is not less than 4cm, and it is placed at room temperature for cultivation;

[0060] b. After 9-14 days, when the barley green seedlings grow to about 15cm, take out the barley seedling tray and drain it, prepare a sterilized towel, soak it in water and wring it dry, lay it flat on the table, and place the barley seedling tray on the towel and wrapped, ready for use;

[0061] c. Take three barley seedling trays, and after fixing one seedling tray, respectively take two seedling trays with long sides sta...

Embodiment 3

[0072] Example 3 (rye seed)

[0073] The present invention is a method for artificially raising Spodoptera frugiperda larvae with a hydroponic seedling tray of rye seeds, comprising the following steps:

[0074] (1) Preparation of rye hydroponic seedling tray:

[0075] a. Weigh 100g of rye seeds, soak them in tap water for 10 hours after washing, and lay them flat in a plastic dish with a net. Reach the height of the mesh without submerging the seeds, the water level under the tray is not less than 4cm, and cultivate at room temperature;

[0076] b. After 9-14 days, when the green rye seedlings grow to about 15cm, take out the rye seedling tray and drain it, prepare a sterilized towel, soak it in water and wring it dry, lay it flat on the table, and place the rye seedling tray on the towel Loaded and wrapped, ready to use;

[0077] c. Take three rye seedling trays, and after fixing one seedling tray, respectively take two seedling trays with long sides stacked against each ...

Abstract

The invention discloses a method for artificially feeding spodoptera frugiperda larvae by using a hydroponic seedling tray of grain seeds, which comprises the steps of preparation of the hydroponic seedling tray of the grain seeds, construction of a feeding frame, feeding of the spodoptera frugiperda larvae and the like, and comprises the following steps: firstly, utilizing the characteristic that the grain seeds such as wheat, barley, rye and corn can be used for hydroponic seedling emergence; seedling trays with holes are used as bearing media of grain seedlings, hydroponic seedling trays with the grain seedlings are manufactured under the indoor condition, meanwhile, the characteristics that three seedling trays are combined into a trapezoidal seedling tray structure and can be vertically stacked are utilized, a multi-layer feeding frame is formed, and sand is provided at the bottoms of the inclined seedling trays for pupation of mature larvae of spodoptera frugiperda. The whole structure is simple, the feeding density is effectively improved, and manual large-scale feeding is achieved.

Description

technical field [0001] The invention belongs to the field of agricultural and forestry biotechnology, and relates to a method for artificially rearing Spodoptera frugiperda, in particular to a method for artificially rearing Spodoptera frugiperda larvae with a hydroponic seedling tray of grain seeds. Background technique [0002] Since corn was introduced to other continents from the Americas in the 15th century, it has become a food resource for human survival and an important cereal crop in my country, and its output ranks second only to rice. Corn has developed into an important food, feed and industrial raw material crop in my country. Especially in the current international situation, the development scale of corn production has become an important factor that determines the situation of food supply and demand in my country, determines the development of animal husbandry and corn processing industry, and is an important part of national food security. Spodoptera frugip...
