Problems solved by technology

[0004] With the continuous deepening of scientific research on fall armyworm and the development of control technology, a large number of insect sources with uniform development and uniform physiology are required, which are limited by the season and the natural growth cycle of fresh-eating hosts, and the larvae of fall armyworm are at a higher density. Under these conditions, the larvae often kill each other, or the larvae bite the pupa, but the method of raising a single larva has many containers, is time-consuming and laborious, and the operation is cumbersome.

Embodiment 1

[0038] Example 1 (wheat seeds)

[0039] The present invention is a method for raising Spodoptera frugiperda in groups by utilizing wheat hydroponic seedling trays, comprising the following steps:

[0040] (1) Preparation of wheat hydroponic seedling tray:

[0041] a. Weigh 100g of wheat seeds, rinse and soak them in tap water for 12 hours, divide them into 5 parts, and place them in a plastic tray with a size of 23×30cm (the size of the wheat seed is about 21×28cm), along the seedling tray. Wheat seeds are sown in the 1, 3 and 5 seedling passages of 23cm, and the sowing width is 5cm. The other seedling tray corresponds to the 2nd and 4th seedling passages of the vacant seedling passage. Wheat seeds are sown so that the water level reaches the mesh hole and does not submerge the height of the seeds. The water level is not less than 4cm, and it is placed at room temperature for cultivation;

[0042] b. After 9-10 days, when the green wheat seedlings grow to 15-20cm, take out t...

Embodiment 2

[0055] The present invention is a method for raising Spodoptera frugiperda in groups by utilizing wheat hydroponic seedling trays, comprising the following steps:

[0056] (1) Preparation of wheat hydroponic seedling tray:

[0057] a. Weigh 125g of wheat seeds, rinse them and soak them in tap water for 12 hours, divide them into 5 parts, place them in a plastic tray with a size of 23 × 30 cm (the size of the wheat seeds is about 21 × 28 cm), along the seedling tray. Wheat seeds are sown in the 1, 3 and 5 seedling passages of 23cm, and the sowing width is 5cm. The other seedling tray corresponds to the 2nd and 4th seedling passages of the vacant seedling passage. Wheat seeds are sown so that the water level reaches the mesh hole and does not submerge the height of the seeds. The water level is not less than 4cm, and it is placed at room temperature for cultivation;

[0058] b. After 9-10 days, when the green wheat seedlings grow to 15-20cm, take out the two wheat seedling tray...

Embodiment 3

[0071] The present invention is a method for raising Spodoptera frugiperda in groups by utilizing wheat hydroponic seedling trays, comprising the following steps:

[0072] (1) Preparation of the wheat hydroponic seedling rearing unit:

[0073] a. Weigh 85g of wheat seeds, rinse them and soak them in tap water for 12 hours, divide them into 5 equal parts, put them in a plastic tray with a mesh size of 23×30cm (the size of the wheat seeds is about 21×28cm), along the seedling tray. Wheat seeds are sown in the 1, 3 and 5 seedling passages of 23cm, and the sowing width is 5cm. The other seedling tray corresponds to the 2nd and 4th seedling passages of the vacant seedling passage. Wheat seeds are sown so that the water level reaches the mesh hole and does not submerge the height of the seeds. The water level is not less than 4cm, and it is placed at room temperature for cultivation;

[0074] b. After 9-10 days, when the green wheat seedlings grow to 15-20cm, take out the two wheat...

Abstract

The invention discloses a method for massively raising spodoptera frugiperda by using wheat hydroponic seedling trays, which comprises the steps of preparation of the wheat hydroponic seedling trays, construction of a raising frame, raising of larvae of the spodoptera frugiperda and the like. And the hydroponic seedling tray with wheat seedlings is manufactured under indoor conditions. The wheat seedlings can be used as foodstuff to feed larvae of the spodoptera frugiperda and can also be used as an oviposition trapping medium to attract adults of the spodoptera frugiperda to oviposition, the vertical overlapping structure of the seedling trays also ensures that the wheat seedlings are not collapsed and pressed during the feeding period and can maintain the characteristics of fresh and alive growth, the wheat seedling trays are easy to obtain indoors, and the sustainable annual cultivation of fresh feed is realized.

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 collectively raising Spodoptera frugiperda by utilizing wheat hydroponic seedling trays. Background technique [0002] Spodoptera frugiperda, belonging to the genus Lepidoptera, Spodoptera frugiperda, is native to the tropical and subtropical regions of the Americas. A major and dangerous migratory pest that threatens agricultural production. In January 2016, Spodoptera frugiperda, which inhabits the American continent, was brought to Nigeria on the west coast of Africa due to commercial and trade shipments, and then it took only two years to sweep 44 sub-Saharan countries and regions, which is very important for food security in Africa. caused a great impact. In 2017, the International Center for Agricultural and Biological Sciences listed FAW as one of the top ten plant ...
