Indoor propagation method and device of radish aphid

Abstract

The invention discloses an indoor reproduction method and device for radish aphids. A specially designed reproduction device is utilized, and Chinese cabbage leaves are adopted for in-vitroreproduction of the radish aphids, wherein the Chinese cabbage leaves are taken off, placed in a cylinder and inoculated with a provenance of the radish aphids, the cylinder is covered with a cylinder cover and vertically placed in an aphid collection tray, and the aphids can be collected 7 days later. The reproduction device is composed of the transparent plastic cylinder, a stainless steel frame, the aphid collection tray and the transparent plastic cylinder cover. Through the device, the technical problems that the Chinese cabbage leaves are prone to corrosion and dehydration and the aphids are hard to collect are well solved. The steps of the method for reproduction of the radish aphids are very simple. The host, namely Chinese cabbages, adopted in the indoor reproduction method for the radish aphids is easy to obtain, limitation of seasons is avoided, the larva breeding process in the traditional aphid reproduction technology is omitted, larva breeding manpower and space and larva period management cost are greatly saved, the reproduction process of the aphids is easier and more convenient, and the method is more suitable for large-scale production of the aphids and has good economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural and forestry pests, and relates to an indoor propagation method and device for radish aphids. Background technique [0002] Fleschner pointed out that the most important thing to raise any kind of organism in large quantities is to be able to produce a large amount of food it needs, and to multiply beneficial insects in large quantities, it is necessary to solve the method of mass production of its host insects, and to choose suitable host plants as a large number of insects. The first step in breeding beneficial insects. Therefore, the first key problem to be solved in the large-scale production of natural enemies of aphids such as ladybugs and hoverflies is the indoor rearing technology of host aphids. Radish aphid [ Lipaphis erysimi (Kaltenbach)] also known as cabbage aphid, cabbage aphid. The radish aphid mainly harms radish ( Raphanus sativus L.), cabbage ( ...

AI Technical Summary

Problems solved by technology

Without exception, the above techniques all use plant seedlings as the host of aphids. At present, there is no research report on using easily obtained parts of plants to propagate aphids in vitro.
