Problems solved by technology

[0003] A kind of predatory natural enemy insect involved in this among them - stinkbug, it can prey on more than 40 kinds of agricultural and forestry insect pests such as Lepidoptera and Coleoptera, its predation is wide, predation amount is large, and predation ability is strong, is a kind of very Potential natural enemy insects, therefore, it has been focused on in the field of biological control. In order to realize the large-scale artificial reproduction of stinkbugs, it must be artificially raised in batches, and armyworm is its main prey food, which has low cost. , less waste, and easy to reproduce, so it involves the large-scale breeding of armyworms. However, in the existing breeding technology, the breeding of armyworms can only be a small amount of breeding, and it is used for natural enemy insect prey experiments. There are some serious problems, such as poor air circulation, easy disease and death of armyworms, low feeding survival rate, high cost, etc.

Embodiment 1

[0019] For the collection and hatching of armyworm eggs, first fix a 10mm wide white high-quality plastic tape on the egg collection device for the attachment of armyworm eggs, and put the armyworm adults and 5% honey water adult nutrient solution in the egg laying stage. In the collection device, finally put the plastic belt with 5000 eggs in the plastic fresh-keeping bag and put it into the artificial climate box for batch incubation;

[0020] The 1st to 3rd instar larvae of the armyworm are reared intensively, and 5000 newly hatched larvae are placed in a sealable 100-mesh gauze breeding device, and are reared on a large scale in an artificial intelligence climate room;

[0021] The 3rd to 6th instar larvae of armyworm were reared separately, and one day after the 3rd instar larvae were reared intensively, 1000 armyworm larvae were scattered and placed in a breeding box of 57cm×37cm×8cm, and raised in an artificial intelligence climate room on a large scale;

Embodiment 2

[0024] For the collection and hatching of armyworm eggs, first fix a 12.5mm wide white high-quality plastic tape on the egg-laying collection device for the armyworm eggs to attach to, and put the armyworm adults in the egg-laying stage and 5% honey water adult nutrient solution in the spawning stage. In the egg collection device, finally put the plastic belt with 5500 eggs in the plastic fresh-keeping bag and put it into the artificial climate box for batch hatching;

[0025] The 1st to 3rd instar larvae of armyworm were reared intensively, and 5250 newly hatched larvae were placed in a sealable 100-mesh gauze breeding device, and were reared on a large scale in an artificial intelligence climate room;

[0026] The 3rd to 6th instar larvae of the armyworm were reared separately, and 1.5 days after the 3rd instar larvae were reared intensively, 1250 armyworm larvae were scattered and placed in a 57cm×37cm×8cm breeding box, and raised in an artificial intelligence climate room o...

Embodiment 3

[0029] For the collection and hatching of armyworm eggs, first fix a 15mm wide white high-quality plastic tape on the egg-laying collection device for the armyworm eggs to attach to, and put the armyworm adults in the egg-laying stage and 5% honey water adult nutrient solution on the egg-laying stage. In the collection device, the plastic belt containing 6000 eggs is finally placed in a plastic fresh-keeping bag and placed in an artificial climate box for batch incubation;

[0030] The 1st to 3rd instar larvae of the armyworm were reared intensively, and 5,500 newly hatched larvae were placed in a sealable 100-mesh gauze breeding device, and were reared on a large scale in an artificial intelligence climate room;

[0031] The 3rd to 6th instar larvae of the armyworm were reared separately, and 2 days after the 3rd instar larvae were reared intensively, 1500 armyworm larvae were scattered and placed in a breeding box of 57cm×37cm×8cm, and raised in an artificial intelligence cli...

Abstract

The invention discloses a method for artificially feeding garmyworms in a large scale. The method is characterized by comprising four steps, i.e., collecting and hatching garmyworm eggs, feeding first to third instar larvae of garmyworms in a concentration way, feeding third to sixth instar larvae of garmyworms in a dispersing way, and enabling mature larvae of garmyworms which are older than sixth instar larvae to pupate in a sand material. Through the four steps, the garmyworms can be artificially fed in a large scale, feeding efficiency is improved, feeding cost is reduced, and survival rate of the garmyworms is guaranteed.

Description

technical field [0001] The invention relates to a method for large-scale artificial breeding of armyworms, in particular to a method for raising armyworms as prey of stinkbugs in the biological control technology of tobacco pests. Background technique [0002] At present, in the production of tobacco leaves, although the biological control technology of controlling tobacco aphids with Aphids aphids has been promoted, it can only be aimed at aphids; Promotional attractants have certain effects, but when pests occur in large numbers, it is still necessary to use chemical pesticides for timely control. Due to the long-term use of chemical pesticides, the resistance of tobacco pests continues to increase, and during the period of large-scale use of pesticides, natural enemy insects are also killed. On the one hand, the safety of tobacco leaves is affected, and on the other hand, the ecosystem of tobacco fields is also destroyed. Tobacco leaf safety and protection of agricultura...
