Embodiment Construction

[0038] A method for overwintering conservation and breeding of aphids, comprising the following sequential steps:

[0039] (a) collecting aphids:

[0040] From August to October, a large wingless aphid will be collected from the wild, and a second and third instar with large wingless, parasitic wasps and no infection by germs will be selected from the aphids bred in the greenhouse in the previous year. Nymphs, wherein the ratio of the number of aphids collected in the field to those collected in greenhouses is 3:7, and the second instar nymphs are 0.8-1.0mm in body length and 0.4-0.5mm in width, and are pale Yellow-green larvae, the third-instar nymphs are larvae with a body length of 1.2-1.3 mm and a body width of 0.6-0.65 mm, which are red-green or light red;

[0041] (b) Tobacco seedlings are connected to aphids:

[0042] Inoculate the above-mentioned collection of aphids on the cultivated fresh tobacco seedlings or radish seedlings or green vegetable seedlings in the gre...

Abstract

The invention provides a method for overwintering species conservation propagation of myzus persicae and belongs to the technical field of prevention and control of aphidius gifuensis. Aiming to solve the problem that the overwintering species conservation of the myzus persicae cannot be realized so that the huge demand for the aphidius gifuensis in the next tobacco planting season is difficultly met in the prior art, the invention provides the method for the overwintering species conservation propagation of the myzus persicae, which comprises the following steps of: a, collecting the myzus persicae; b, inoculating the myzus persicae to tobacco seedlings; c, removing toxins from the myzus persicae; d, purifying and rejuvenating the myzus persicae; e, performing the overwintering species conservation of the myzus persicae; and f, enlarging the propagation of the myzus persicae. The method has the advantages of successfully realizing the large-scale propagation of the myzus persicae, ensuring quality and quantity of the young myzus persicae, providing enough high-quality myzus persicae for the large-scale propagation of the aphidius gifuensis in next year, and creating better ecological benefit, economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of preventing and controlling the aphids, and in particular relates to a technique for preserving and breeding the aphids in winter in preparation for mass breeding of the aphids after overwintering. Background technique [0002] The traditional control of Aphis persica mainly relies on chemical control. Due to the long-term application of large amounts of chemical pesticides, Aphis persica has developed strong resistance to various pesticides, which has resulted in increased pesticide usage and reduced efficacy. Pesticides have caused serious damage to various natural enemies of aphids, and the number has decreased sharply. With the increase of pesticide usage, the pesticide residues in tobacco leaves are becoming more and more serious, and the pollution to the natural environment is also increasing. [0003] In order to solve the above-mentioned problems, biological control technology has appeared at prese...
