Problems solved by technology

The third is to secrete honeydew on the leaves and breed mold, which will cause the tobacco leaves to produce paste after roasting and lose their commercial value.
This control method has been successful in Yunnan, but in northern China, a greenhouse that can maintain a constant temperature is necessary to preserve the aphid species. The construction cost of a greenhouse that can maintain a constant temperature is high, and the investment in constant temperature facilities and equipment is high.

Embodiment Construction

[0018] A kind of method that utilizes winter storage Chinese cabbage to carry out aphid winter seed preservation, and its method comprises the following steps:

[0019] Step 1: Harvest Chinese cabbage with firm core, no insects, no diseases, roots and no aphid resistance in early winter;

[0020] Step 2: Remove the loosely wrapped leaves of the Chinese cabbage under aseptic conditions, and gently uncover one to three layers of leaves on the top of the Chinese cabbage;

[0021] Step 3: Inoculate a specific number of aphids on the top of the cabbage that has uncovered one to three layers of leaves, and reset the uncovered cabbage leaves in sequence;

[0022] Step 4: place the Chinese cabbage root after picking up aphids on a medium containing specific moisture in a sterile environment that maintains a specific temperature and specific humidity and has ventilation conditions;

[0023] Step 5: Inoculate the seed aphids that have been preserved for a specific time in step 4 on the...

Abstract

The invention relates to a method for conducting aphid conservation in winter by means of winter cabbages. The problems that in the prior art, in the vast northern area of the Yangtze River in our country, a greenhouse capable of keeping a constant temperature must be arranged for achieving conservation of aphids of myzus persicae sulzer species, and the investment on building of the greenhouse capable of keeping the constant temperature and facilitates and equipment for temperature constancy is high are solved. Due to the fact that aphid conservation is conducted by means of the winter cabbages, the problem that pathogens utilizing other aphid conservation hosts are propagated to tobaccos through the aphids is solved, and the problem that aphid conservation is conducted by means of other aphid hosts, and then cabbages are utilized as propagation hosts to conduct detoxification on the aphids is solved.

Description

technical field [0001] The invention relates to the technical field of biological control of diseases and insect pests, in particular to a method for using winter-stored Chinese cabbage to preserve seeds of aphids in winter. Background technique [0002] The tobacco aphid, also known as the peach aphid, is one of the main pests of tobacco. Its damage is mainly manifested in three aspects: one is the spread of mosaic virus disease, which seriously affects the quality of tobacco leaves after flaking and roasting. This is the most serious damage caused by aphids an aspect of The second is to directly suck young leaves and tender stems, so that the growth of the tobacco plants becomes weaker, the tobacco leaves become smaller and thinner, the inclusions decrease, and the quality deteriorates. The third is to secrete honeydew on the leaves and breed molds, resulting in the production of paste sheets after the tobacco leaves are roasted, which loses commercial value. [0003] In...
