[0004] Armyworm is a metamorphic insect with four developmental stages: adult, egg, larva and pupa. Different developmental stages have different requirements for the environment, and the larvae have the habit of killing each other in the case of food shortage, so artificial breeding It is a complex process that requires a lot of manpower and material resources
After the armyworm larvae grow to the third instar, their food intake explodes and the space requirements are large. It is no longer suitable to use plant materials for feeding. Pupation is done in the soil, and pupae are manually picked and transferred to adult cages for eclosion and oviposition. Not only does it require a lot of labor and space, but repeated operations are also likely to damage the activity of armyworms and reduce the amount of eggs laid. Selling armyworm eggs is expensive, 1 yuan / grain in summer and 2 yuan / grain in winter, which has severely limited the development of the armyworm industry and its related natural enemy industries

Embodiment 1
[0130] The breeding of Mythimna separata provided in this embodiment includes a rearing box 10, a box cover 21, a feces recovery tray 22, an isolation net 23, a feed holding part 24, a fecal filter 31, a pupa recovery box 41, an egg laying cage 51, and an egg laying part 52 and feeding pieces 53. The armyworm breeding device has a first state (corresponding to the first component 20 below), a second state (corresponding to the second component 30 below), and a third state (corresponding to the following The third component 40), the fourth state (corresponding to the fourth component 50 below) and the fifth state.
[0131] Please refer to figure 1 , The first assembly 20 includes a box cover 21, a fecal recovery tray 22, an isolation net 23 (not shown), and a feed holding member 24. The breeding box 10 is enclosed by four side walls, the side walls are transparent organic glass plates, and the upper and lower surfaces of the breeding box 10 penetrate each other. The length of th...
Embodiment 2
[0147] This embodiment provides a method for raising armyworms. The armyworm feeding device provided in Example 3 is used to raise the armyworms according to the following steps:
[0148] The armyworm larvae that have developed to 3-9 days are inserted into the terrarium 10 in the first state (that is, the terrarium 10 with the first assembly 20), the lid 21 is closed, and the larvae are raised at 25°C.
[0149] When the food intake of the armyworm larvae increases, the terrarium 10 in the second state (that is, the first assembly 20 is replaced with the second assembly 30) continues to be reared until the armyworm larvae develop into 6-instar mature larvae.
[0150] When the feeding of the mature larvae decreases, in the terrarium 10 in the third state (that is, the second assembly 30 is replaced with the third assembly 40), the lid 21 of the third assembly 40 is covered with plastic sheet to make the mature The humidity of the growth environment of the larvae is 80%.

Abstract
The invention provides a mythimna separata feeding device and method, and belongs to the technical field of insect feeding. The mythimna separata feeding device comprises a feeding box, a box cover, aexcrement recycling tray, an isolation net, a feed containing piece, an excrement filter screen, a pupa recycling box, an egg laying cage, a moisture preserving box, a moisture preserving piece, a feeding piece and an egg laying piece. Under a first state, the box cover is arranged on the upper surface of the feeding box, the isolation net is detachably connected to the bottom of the feeding box,the excrement recycling tray is detachably connected to the lower portion of the isolation net, and the feed containing piece is arranged in the feeding box; under a second state, the excrement filter screen is detachably connected to the bottom of the feeding box; under a third state, the pupa recycling box is arranged below the feeding box; under a fourth state, the egg laying cage is arrangedat the top of the feeding box, and the moisture preserving box covers the egg laying cage; and under a fifth state, the feeding piece and the egg laying piece are additionally arranged, and the moisture preserving piece covers the feeding piece and the egg laying piece. According to the device, mythimna separata with the age of more than 1 year is taken as a feeding whole body through cooperationof the assemblies, so that the manpower, space and feeding cost are greatly saved, and the feeding effect is good.
Description
Technical field [0001] The invention relates to the technical field of insect breeding, in particular to a device and method for breeding armyworms. Background technique [0002] Armyworms are insects of the Lepidoptera Noctuidae, also known as marching insects. Their larvae can harm wheat, rice, millet, corn and other cereal crops and cotton, beans, vegetables and other 16 families and 104 species of plants. When the larva reaches At 3 years of age, the food intake increases, and he likes to live in groups. When it happens, all crop leaves can be eaten up, and then transferred to another plot to continue the damage, often causing devastating damage to crop yields. In recent years, it has often been used in corn production in China. The outbreak in the district has caused the polishing of corn and severely reduced the yield of corn. Mythimna separata has become a nationally important agricultural pest due to its characteristics such as clustering, migratory, omnivorous, and over...
