A kind of indoor rearing method of bean aphid

Abstract

The invention discloses a method for indoor propagation of bean aphids. The method comprises raising red bean seedlings and multiplying bean aphids. The red bean seedling raising includes the steps of preparing soaking liquid for bean seeds, soaking bean seeds, accelerating germination, raising seedlings, and the like. The propagation of soybean aphid includes steps such as the inoculation of soybean aphid, the propagation of soybean aphid of provenance, and the propagation of soybean aphid for breeding natural enemies. The method used in the present invention has low requirements on temperature, humidity and light, and fiber cloth is used to maintain the humidity of the seedling raising substrate during seedling raising.

Description

technical field

[0001] The invention belongs to the technical field of biological control of agricultural and forestry pests, and relates to a method for breeding natural enemy hosts, in particular to an indoor breeding method for bean aphids. Background technique

[0002] 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 reproduction technology of natural enemies of aphids. bean aphid Aphis craccivora Koch, also known as alfalfa aphid and peanut aphid, is a kind of aphid with fast growth and reproduction and wide temperature adaptability. It is currently the most widely used host for the reproduction of aphid natural enemies. Aphidoletes sp (Beijing Academy of Agriculture and Forestry Sciences), using broad beans to raise bean aphids to breed Heterochromia (Hubei Tobacco Company), using broad bean seedlings to raise bean aphids to breed Aphidia syringae (Yunnan Tobacco Company), etc...

[0033] A kind of indoor rearing method of bean aphid, concrete operation steps are:

[0034] (1) Cultivation of bean sprouts

[0035] ①Preparation of bean seed soaking solution: Measure an appropriate amount of sterile water, weigh the drug A gibberellin, pour it into sterile water and stir evenly, and prepare a soaking solution with a concentration of 0.5 mg / L;

[0036] 2. Soaking of bean seeds: after purchasing red bean seeds on the market, put the red bean into a plastic basin, flatten it, pour in the soaking liquid, the water level is 2cm higher than the bean seeds, and the soaking time is 12h; the plastic basin The size is selected according to the number of soaked beans;

[0037] ③ Germination of bean seeds: Take out the soaked red bean seeds, drain the water, put them together with the plastic basin containing red bean seeds into a plastic film bag, seal the seal, and the germination time is 2 days until the bean seeds are red Take out the adzuki bean when it grows a ...
