Problems solved by technology

[0002] Beet armyworm (Spodoptera exigua Hübner) and other lepidopteran pests are the main pests on vegetables, all of which have the characteristics of fulminant, gluttony, and easy to develop drug resistance (Si Shengyun et al. 2009; Liu Xiangyang et al. 2007; Moulton et al 2000) , resulting in increased control difficulty, increased control costs, and excessive pesticide residues, etc., directly threatening food safety, hindering the development of foreign trade, and destroying ecological balance (Lukai et al. 2005; Huang Yingjia 2013)

Embodiment 1

[0073] A method for raising beet armyworm, carried out according to the following steps:

[0074] A. Cut the egg paper with scissors into small pieces and place it in a sterile petri dish. After the eggs turn black, put a small amount of feed, and discard the egg paper after the larvae hatch completely;

[0075] B, 1-3 instars are raised in petri dish always, and 280 larvae are put into feed in each petri dish;

[0076] C. After the larvae grow to the 3rd instar, there are 9 larvae in each petri dish, and the larvae are distributed to other petri dishes with a writing brush, and the feed is put in, and the excrement is removed at the end of the 4th instar, and the feed is added, and the feed is raised until During the pre-pupation stage, the feed was just eaten, and it was allowed to pupate in a petri dish.

[0077] The feed is a feed that is beneficial to improving the reproductive efficiency of the beet armyworm.

[0078] The feed that is conducive to improving the reprodu...

Embodiment 2

[0091] A method for raising beet armyworm, carried out according to the following steps:

[0092] A. Cut the egg paper with scissors into small pieces and place it in a sterile petri dish. After the eggs turn black, put a small amount of feed, and discard the egg paper after the larvae hatch completely;

[0093] B, 1-3 instars are raised in petri dish always, and 300 larvae are put into feed in each petri dish;

[0094] C. After the larvae grow to the 3rd instar, there are 8 larvae in each petri dish, and the larvae are distributed to other petri dishes with a writing brush, put in the feed, and the excrement is removed at the end of the 4th instar, and the feed is added to raise it until During the pre-pupation stage, the feed was just eaten, and it was allowed to pupate in a petri dish.

[0095] The feed is a feed that is beneficial to improving the reproductive efficiency of the beet armyworm.

Embodiment 3

[0109] A method for raising beet armyworm, carried out according to the following steps:

[0110] A. Cut the egg paper with scissors into small pieces and place it in a sterile petri dish. After the eggs turn black, put a small amount of feed, and discard the egg paper after the larvae hatch completely;

[0111] B, 1-3 instars are raised in petri dish always, and 250 larvae are put into feed in each petri dish;

[0112] C. After the larvae grow to the 3rd instar, there are 10 larvae in each petri dish, and the larvae are distributed to other petri dishes with a writing brush, and put in the feed, and the excrement is removed at the end of the 4th instar, and the feed is added, and the feed is raised until During the pre-pupation stage, the feed was just eaten, and it was allowed to pupate in a petri dish.

[0113] The feed is a feed that is beneficial to improving the reproductive efficiency of the beet armyworm.

[0114] The feed that is conducive to improving the reproduct...

Abstract

The invention provides a method for breeding beet armyworm. Different beet armyworm unit area breeding amounts are set for different beet armyworm growing stages, and thus healthy and safe growth of beet armyworm is promoted. Feed is prepared from the main ingredients of corn flour, yeast powder, citric acid, sodium benzoate, saccharose, vitamin C, folium mori, radix angelica sinensis powder, semen cassiae powder and water. The two traditional Chinese medicine materials of radix angelica sinensis powder and semen cassiae powder are added on the basis of traditional feed for beet armyworm and can improve the immunity of beet armyworm in combination with folium mori, and thus the effect of increasing the larva survival rate, pupation rate and eclosion rate of beet armyworm is achieved; detection shows that the propagation efficiency of beet armyworm bred with the feed can be improved by 10% or above.

Description

technical field [0001] The invention relates to the field of insect breeding, in particular to a method for raising beet armyworm. Background technique [0002] Beet armyworm (Spodoptera exigua Hübner) and other lepidopteran pests are the main pests on vegetables, all of which have the characteristics of fulminant, gluttony, and easy to develop drug resistance (Si Shengyun et al. 2009; Liu Xiangyang et al. 2007; Moulton et al 2000) , resulting in increased control difficulty, increased control costs, and excessive pesticide residues, etc., directly threatening food safety, hindering the development of foreign trade, and destroying ecological balance (Lukai et al. 2005; Huang Yingjia 2013). [0003] Establishing beet armyworm strains, optimizing beet armyworm artificial breeding technology, and providing a large number of normal and uniform sources of test insects are the basic work of many researches on insect physiology and biochemistry, insect genetics and insect toxicolog...
