Problems solved by technology

[0006] However, there are still technical difficulties in the control of Aphis persicae in Shaanxi area. For example, the technology of controlling A. persicae in Shaanxi area is still in its infancy, and the reproduction and release technology of A. persicae is not mature enough to be used efficiently To prevent and control Aphids persicae, the existing reproduction and release technology of A. persicae cannot exert its maximum effect

Embodiment Construction

[0032] The present invention will be specifically introduced below in conjunction with specific embodiments.

[0033] 1. Cultivation of aphid hosts

[0034] 1. Select a tobacco variety: select a tobacco variety with strong disease resistance, aphid preference, and high aphid reproduction. In this example, we selected Yunyan 99.

[0035] 2. Seedling cultivation: Use a greenhouse with a 60-mesh insect-proof net to cultivate seedlings. The temperature of the greenhouse is controlled within the range of 22±5°C, and the humidity is controlled within the range of 60%-70%. The method of raising seedlings is the floating seedling method. , Sowing in batches, 100 plants per plate.

[0036] 3. Transplanting: 20d-25d before transplanting in the flue-cured tobacco field, select 5-6 pieces of true leaf disease-free tobacco seedlings for transplanting, and carry out site preparation, soil moisture and ridging according to standardized production, and open 2 rows of double rows in one shed ...

Abstract

The invention discloses a localization method for breeding and releasing of aphidius gifuensis ashmead in the Shaanxi area. The method comprises the following steps of 1 myzus persicae sulzer host breeding, wherein an appropriate tobacco variety is selected for seedling raising and transplanting; 2 aphid screening and reproduction, wherein aphid species are collected for breeding and screening; 3 aphidius gifuensis ashmead reproduction through myzus persicae sulzer, wherein bees are collected, after copulation, the phidius gifuensis ashmead and the host myzus persicae sulzer natural breed, and mummified aphids are obtained; 4, bee releasing, wherein bee releasing operation is conducted in the initial stage of the myzus persicae sulzer occurrence, the frequency and quantity of bee releasing are determined according to the myzus persicae sulzer occurrence, mummified aphid seedlings can be placed, and adult bees can be directly released. The method has the advantages that according to the practical situation of the Shaanxi area, large scale of local aphidius gifuensis ashmead reproduction and releasing, the control cost of a tobacco grower for myzus persicae sulzer is reduced, and the quality of local tobacco leaves is improved.

Description

technical field [0001] The invention relates to a method for breeding and releasing the Aphidia persicae, in particular to a localized method for breeding and releasing the Aphisia persicae, and belongs to the technical field of biological control of agricultural pests. Background technique [0002] The tobacco aphid, also known as the green peach aphid, is the most serious insect harmful to tobacco in the world. It likes to gather on the back of young leaves or tender stems of tobacco plants to prick and suck food juice. In severe cases, the tobacco plants will grow slowly, the plants will be short, the leaves will shrink, become smaller, and thinner. After the damaged tobacco leaves are baked, the leaves will turn brown, lack luster, be difficult to regain moisture, be easily broken, and have reduced flammability. In addition, in addition to the harm caused by directly stabbing the smoking plants, the honeydew secreted by the aphid often induces bituminous coal disease, wh...
