Artificial aphid propagation method

Abstract

The invention discloses an artificial aphid propagation method. Peas are utilized as a host plant to culture aphids and collect, select and store the propagated aphids. The artificial aphid propagation method realizes the large-scale, low-cost and standardized production of the aphids, makes the annual production of the aphids be possible and provides sufficient fodder or adding ingredients of artificial fodder for the growth and the propagation of natural enemy insects.

Description

technical field [0001] The invention relates to an artificial propagation method of insects, in particular to an artificial propagation method of small insects-aphids with piercing-sucking mouthparts. Background technique [0002] Aphids, also known as greasy insects, early insects, honey insects, ant insects, etc., are one of the main control objects for agricultural and forestry plant protection. Aphids are small in size, with a body length of 1.5-4.9 mm, most of which are about 2 mm. Belonging to Homoptera, there are 107 genera and 2280 species, all over the world, and 260 species are known in my country. Aphids have strong fecundity, and can reproduce 10-30 generations in one year, and the phenomenon of overlapping generations is prominent. The temperature is 16-22°C, which is the most suitable for aphid breeding, and drought or excessive plant density is conducive to aphid damage. Aphids have a wide variety of host plants, involving 267 families and 2120 genera, espe...

AI Technical Summary

Problems solved by technology

Although these plants can reproduce a certain number of aphids, they have disadvantages such as long reproductive cycle, low yield, requiring a greenhouse, and difficult collection; in addition, these host plants are difficult to achieve standardized cultivation, so standardization of aphid breeding cannot be realized

[0006] (2) There is no suitable breeding method

The existing aphid breeding method is only to insert aphids when the host plant grows to a certain stage, which cannot make full use of the nutrition of the host plant. At the same time, it is greatly interfered by the resistance of the host plant. When the host plant grows robustly, the aphid population develops slowly. There is even a decline

In addition, it is difficult to control natural enemy insects in the production environment, and it is difficult to remove natural enemy insects when they invade the breeding environment, resulting in the population of aphids being always suppressed at a low level

[0007] (3) There is no large-scale, rapid and mass-produced technology for aphids

The existing aphid breeding method often takes 30-40 days from inoculation to harvesting, so it consumes a lot of energy, uses a lot of manpower, and occupies a large amount of greenhouse space, and cannot carry out centralized output and standardized production

[0008] (4) strong seasonal dependence

At present, breeding aphids can only be carried out artificially in seasons suitable for the growth of aphids, usually within 2-3 months of spring and autumn. At other times, it is difficult to guarantee the temperature and humidity, or the host plants are difficult to obtain, so it cannot be carried out in large quantities. Production

[0009] (5) There is no good collection method

Because aphids grow on plant leaves, it is very difficult to collect them. The common collection method is to use a brush, which is generally difficult to brush off. At the same time, impurities such as plant leaves will be collected together, so it is impossible to obtain pure aphid clusters.

[0010] (6) There is no good storage method

The existing aphid storage methods cannot store aphids in large quantities for a long time, because the aphids that are separated from the host plant will soon die, lose water quickly and become shriveled and lose their use value
