Embodiment Construction

[0021] A method for diffusing, multiplying and releasing the heterochromia to prevent and control aphids, the steps of the method are as follows:

[0022] (a) Carry out the propagation of aphids in the diffusion breeding shed, and the diffusion breeding shed is covered with an insect-proof net 7; the tobacco seedlings are cultivated by the floating method, and when the tobacco seedlings have 5 to 6 true leaves, put the aphid-bearing tobacco leaves on the tobacco seedlings and then put the female and male adults of Heterochromatia collected in the field into the insect-proof net, so that the Heterochromia eats Aphid, mates, lays eggs, hatches and develops into larvae, or directly collects young larvae, or After the larvae pupate, the pupae are retrieved to emerge at room temperature, and the emerged adults are fed with aphids and placed in a refrigerator for storage; the aphid-bearing tobacco leaves refer to tobacco leaves with aphids breeding;

[0023] (b) Select healthy young...

Abstract

The invention discloses a diffusion breeding and releasing method for preventing myzus persicae through harmonia axyridis. The myzus persicae is bred in a diffusion breeding shed, and an insect-proof net (7) covers the diffusion breeding shed; a tobacco seedling is cultivated through a floating method; when the tobacco seedling has five to six true leaves, tobacco leaves with the myzus persicae are put on the tobacco seedling to breed the myzus persicae; male and female harmonia axyridis adults captured in the wild are put into the insect-proof net, eat the myzus persicae and then mate to lay eggs; the eggs are incubated into larvae, or low-age larvae are directly collected, or after the larvae are pupated, pupae are taken back for eclosion at room temperature; the eclosion adults are fed with the myzus persicae and are put into a refrigerator for refrigeration and storage; the low-age larvae or the adults of the harmonia axyridis are put into a low-age larva transporting and releasing device (9) or an adult transporting and releasing device (10); the low-age larvae or the adults of the harmonia axyridis are released to a field according to a ratio of the harmonia axyridis to the myzus persicae of 1:(100-120) in a preliminary forming stage of the myzus persicae in the field. According to the method, the breeding speed rate of the harmonia axyridis can be remarkably improved, and the field pest control efficiency is improved in a mode of preventing the myzus persicae through the harmonia axyridis.

Description

technical field [0001] The invention belongs to the technical field of biological control, in particular to a method for preventing and treating aphids by utilizing the heterochromia. Background technique [0002] At present, my country's tobacco leaf production has entered a new period of development. All tobacco production areas are building ecological characteristic high-quality tobacco leaf raw material bases in accordance with the "ecological, safe, characteristic, high-quality, and efficient" production method to further improve the quality of tobacco leaves. However, the large-scale cultivation of tobacco has brought a severe test to the control of diseases and insect pests. The tobacco aphid is one of the important pests that harm tobacco leaves. Its piercing tobacco sap causes the leaves to turn yellow, shrink, and even deform and die. In the past, chemical pesticides were often used for control, which could easily lead to enhanced resistance to tobacco aphids, pes...
