Description

Armyworm feeding device and method

Technical Field

The invention relates to the technical field of insect feeding, in particular to a sticky insect feeding device and method.

Background

The armyworm is an insect belonging to the lepidoptera noctuidae family and is also called a marching insect, the larva of the armyworm can damage cereal grain crops such as wheat, rice, millet and corn and more than 16 plants such as cotton, beans and vegetables, when the larva reaches 3 years old, the food intake is increased, the larva likes to be colonized, when the larva occurs, all leaves of the crop can be eaten by light and then transferred to another land for continuous damage, destructive damage is often caused to the crop yield, in recent years, the larva often explodes in the corn production area of China, the polished rod phenomenon of the corn is caused, and the corn yield is seriously reduced. Armyworm has become a nationwide important agricultural pest due to its characteristics such as clustering, migration, omnivory and fast eating.

Although the armyworm is an important agricultural pest, the armyworm has many benefits in production and life, can be used as an insect for scientific research, researches the resistance of crops to the armyworm, researches the sensitivity of drugs to the armyworm, and can also be used as a top-grade food for the production of natural enemy insects and viruses to influence the development of natural enemy and virus pesticides, so that the artificial feeding of the armyworm has important significance for the research and industrial development.

The armyworm is a metamorphosis insect and has four development stages of imago, egg, larva and pupa, different development stages have different requirements on the environment, and the larva has the habit of self-killing under the condition of food shortage, so that the artificial feeding is a complex process and needs to consume a large amount of manpower and material resources. After the mythimna separata larvae develop to be more than 3 years old, the food intake is burst, the space requirement is large, plant materials are adopted for feeding, the environment which needs to be changed continuously to feed is not suitable for feeding to ensure the living environment, the aged larvae which develop to be 6 years old need to be drilled into the soil to be pupated indoors, the pupae are manually picked and transferred into an adult rearing cage for eclosion and spawning, the labor and space requirement is large, the activity of the mythimna separata is easily damaged by repeated operation, the spawning amount is reduced, the price of the marketed mythimna separata egg granules is high, 1 yuan per granule in summer and 2 yuan per granule in winter, and the development of the mythimna separata industry and related natural enemies thereof is.

In the present application, the feeding elements can be suspended in the spawning cage via the string and the mesh of the top net, the number of feeding elements suspended in the spawning cage being at least 1, for example 1-10. Preferably, the suspension height of the feeders in the spawning cage differs when the number of feeders exceeds 1. By reference, the adjustment of the suspension height can be achieved by adjusting the length of the string.

In some embodiments, the feeder contains nutrients that provide energy for adult development, and the nutrients may include, for example, honey water, and in some preferred embodiments, honey water at a concentration of 8-12 wt%. The honey water can be prepared by mixing commercially available honey with water, and the type of honey is not limited.

In addition, the invention also provides a mythimna separata breeding method, which adopts the mythimna separata breeding device to breed according to the following steps:

and (3) inoculating the myxozoon larvae which grow for 3-9 days into a feeding box in the first state for feeding, covering a box cover in the feeding process, and controlling the feeding temperature to be 24-26 ℃.

When the feeding amount of the myxoplasma larvae is increased (which can be understood as entering a binge eating period), the feeding is continued in the feeding box in the second state until the myxoplasma larvae develop into 6-year-old mature larvae. It will be appreciated that at this stage, the mythimna separata rearing device may be directly changed from the first state to the second state.

And feeding the aged larvae in the mythimna separata feeding device in a third state when the feeding amount of the aged larvae is reduced. It will be appreciated that at this stage, the mythimna separata rearing device may be directly changed from the second state to the third state. At this time, a cover of the vermin raising apparatus is covered with a plastic cloth to maintain the humidity of the growing environment of the aged larvae at 70-80%.

After all the aged larvae are drilled into the fine soil in the pupa recycling box, the larvae are raised in the raising box under the fourth state. It is understood that, at this stage, the mythimna separata rearing device is directly changed from the third state to the fourth state. At this time, a moisture preservation box is covered outside the spawning cage of the armyworm feeding device to ensure that the humidity of the fine soil is 70-80%.

And feeding in the feeding box in the fifth state when eclosion armyworm emerges from the pupa recycling box.

The replacement of the isolation net and the excrement filter screen in the armyworm feeding device can combine the feeding of 1-6-year-old armyworms without replacing feeds, thereby greatly reducing the feeding labor and feed cost; the feeding space of the armyworms is greatly improved due to the vertical arrangement of the feed containing pieces, and the space cost is reduced; the combined parts of the feeding box, the pupa recovery box and the spawning cage combine pupation, eclosion and spawning together, manual operation is not needed, damage to armyworms is reduced, and labor and space cost is greatly reduced. By arranging corresponding structures according to different growth stages of the armyworms, the armyworms of more than 1 year can be taken as a whole for feeding, so that the labor, the space and the feeding cost are greatly saved. The feeding method adopts corresponding devices for feeding according to different growth stages of the armyworms, and the feeding effect is good.
