Aphidius gifuensis Ashmaed and Encarsia formosa simultaneous breeding method

Abstract

Disclosed is an Aphidius gifuensis Ashmaed and Encarsia formosa simultaneous breeding method. Tobaccos or eggplants which is or are poor in insect resistance is or are utilized as host plants of myzus persicae and bemisia tabaci, the myzus persicae and the bemisia tabaci are bred together in a simultaneous breeding chamber after corresponding pest species and bee species are obtained through classified breeding on the myzus persicae, Aphidius gifuensis Ashmaed, the bemisia tabaci and Encarsia Formosa, the Aphidius gifuensis Ashmaed and the Encarsia Formosa are inoculated on simultaneous breeding chamber plants, and accordingly the simultaneous breeding of the Aphidius gifuensis Ashmaed and the Encarsia Formosa is implemented. The breeding utilization rate of the host plants is greatly improved, more than 10000 Aphidius gifuensis Ashmaed and more than 12000 Encarsia Formosa can be simultaneously bred on every host plant in the simultaneous breeding chamber, and the breeding efficiency is improved by 40 to 60% under the same facility condition in comparison with the common method. The two types of natural parasitic wasps can be bred simultaneously and accordingly the problem of the simultaneous harm of the two types of pests of the myzus persicae and the bemisia tabaci to the actual production can be effectively solved, the control effect is good, the efficiency is high, and the technology of prevention and control on multiple pests is improved due to the biological diversity.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural and forestry pests, and in particular relates to a method for the co-propagation of Aphidia persicae and Aphidia persicae. Background technique [0002] Aphids parasitize on the plants of Solanaceae, Cruciferae, Compositae, Leguminosae, Chenopodiaceae, Convolvulaceae, Rosaceae and other crops. The adults and nymphs suck the juice in the plants, causing the leaves to shrink and turn yellow. , the stems and pedicels are twisted and deformed, and the plants are short and short, spreading viral diseases during the smoking process, and excreting honeydew to induce tobacco leaf soot disease. Aphids are more harmful in agricultural and forestry production. [0003] As a worldwide pest, whitefly hosts a wide range of plants, with 653 known species belonging to 112 families. Adults and nymphs of whitefly use file-sucking mouthparts to suck plant juice, causing the leaves of the ...

Problems solved by technology

[0005] In agricultural production, when the two pests of tobacco aphid and whitefly harm crops at the same time, the single-species parasitoid breeding technology is used in the prior art to breed the Aphidia persicae and the wasp respectively, so as to control the two kinds of pests, aphid and whitefly. Pests have the problems of long breeding cycle, low efficiency, many procedures, high cost, and greatly reduced control effect. A method for co-propagating of Aphidia migneosa and Lepidox wasp is provided. The implementation steps of the method include:
