Embodiment 1

[0020] Using two facilities, the nursery greenhouse and the insect culture room, the broad bean was used as the host plant for the reproduction of the pea aphid, and the pea aphid was used as the aphid for feeding the Heterochromia. Specific technical measures such as artificial breeding artificially multiply the Heterochromia for agricultural control of aphids.

[0021] Wherein the step of cultivating broad bean plant in a large number in greenhouse is:

[0022] Cultivate broad bean plant, 1, buy the matrix culture soil that is used for raising seedlings in the market, then put culture soil into the plastic flower pot that the diameter of getting ready is 26.0cm for subsequent use; Buy broad beans with no diseases and pests and full grains in the market as bean seeds, soak them in clean water for 12-24 hours, and sow after the beans absorb water and the beans swell; 3. The sowing method is to evenly sow broad bean seeds in each flower pot Keep a distance of about 2-3cm, then...

Embodiment 2

[0034] 1. Cultivate broad bean plants in nursery greenhouses

[0035] 1. Culture soil preparation

[0036] The matrix culture soil that is used for raising seedlings is purchased in the market to cultivate broad bean plants. The culture soil is packed into a plastic flower pot with a diameter of 26.0 cm for subsequent use.

[0037] 2. Sowing Broad Beans

[0038] Soaking broad bean seeds: buy plump broad beans without diseases and insect pests from the market as bean seeds, soak them in water for 12-24 hours, and wait until the seed coats of broad bean seeds are swollen and plump to be used for sowing.

[0039] Sowing method: Sow broad bean seeds evenly in each flowerpot, keep a distance of about 2-3cm between the seeds, and then cover the seeds with 1-2cm thick cultivation soil, water in time to make the cultivation soil fully moist.

[0040] 3. Management measures:

[0041] Placement of flower pots: There are seedling racks built in the seedling cultivation shed, which ar...

Abstract

The invention relates to an artificial mass propagation method of harmonia axyridis. Two facilities of a seedling raising greenhouse and an insectary are adopted, broad beans are used as host plants for propagating pea aphids which are used as aphids for feeding the harmonia axyridis, and the harmonia axyridis which is used for agricultural control over the aphids can be manually propagated in a large quantity through specific technical measures of broad bean plant breeding, pea aphid inoculation and propagation, artificial breeding of the harmonia axyridis and the like. Healthy broad bean sprouts are bred with broad bean seeds, the pea aphids are inoculated with the broad bean sprouts and propagated, then the pea aphids are collected to feed larvas and adults of the harmonia axyridis, and a large quantity of the larvas and the adults of the harmonia axyridis are propagated to be released in agricultural production areas to control the aphids of all kinds, so that the biological control over the aphids is realized, and the pollution and safety problems caused by chemical control is avoided or reduced.

Description

technical field [0001] The invention relates to a method for artificially multiplying heterochromia in large quantities. Background technique [0002] The host plant-pest-natural enemy is an important topic in the current agricultural biological control, and it is also an important basis for finding sustainable pest control methods. Natural enemies are mainly divided into parasitic natural enemies and predatory natural enemies. Among the parasitic natural enemies, the biological control of parasitoids is a relatively mature control method at present, and the application of predatory natural enemies is relatively scarce. Heterochromia is an effective predatory natural enemy of aphids, various scale insects and whiteflies. More and more advantages have been paid more and more attention in the biological control of aphids. Although the predecessors have carried out a large number of researches on the rearing of the heterochromia, they have not formed a systematic, comprehensi...
