Embodiment 1

[0025] Embodiment 1, the screening of avoidance plant

[0026] (1) Test aphids

[0027] The sex-taxis behavior was determined by using wolfberry aphids reared indoors. Lycium barbarum aphids collected from Zhongning wolfberry fields in Ningxia were inoculated on wolfberry grown in the greenhouse. After two days, the inoculated aphids were removed, and wingless adult aphids with basically the same individual size and state were selected. as test insects.

[0028] (2) Selection of approaching and avoiding plants

[0029] According to the resource characteristics of Ningxia, 13 kinds of plants including marigold, fenugreek, perilla, alfalfa, clover, mosquito repellent, violet, scopolamine, cumin, carnation, cosmos, lavender and mint were screened. Three species of Lycium barbarum, Lycium barbarum, and broad bean were used as host plants for the tested aphids, and the effects of 13 plant volatiles on the behavior of Lycium barbarum aphids were determined.

Embodiment 2

[0037] Embodiment 2, the field planting test of evasive plant

[0038] (1) Arrangement of investigation points in the experimental area of ​​approaching and avoiding plant intercropping

[0039] The implementation time of this experiment was 2016. A total of 70 sampling points were arranged in the intercropping test area, including 27 on the avoiding plants and 43 on the Lycium barbarum; the survey time was July 10, July 17, July 30, On August 12, August 19, August 27, September 1, September 15, and September 20, there were 9 surveys in total. Nine survey points (①~⑨) were evenly set up in each plot, and two different ground traps were set under the wolfberry tree at each point.

Abstract

The invention discloses a method for preventing and controlling Chinese wolfberry aphids. According to the method, a pest-prevention plant is introduced to a Chinese wolfberry garden. The pest-prevention plant is any one of marigold, fenugreek, perilla, alfalfa, clover, mozzie buster, violet, hembane, cumin, dianthus chinensis, calliopsis, lavender and mint. The method for preventing and controlling the Chinese wolfberry aphids is based on the concept of ecological regulation for prevention and control of pests, and the cultivation of the pest-prevention plant in the Chinese wolfberry garden effectively suppresses the Chinese wolfberry from being damaged by the aphids and can achieve continuous control. The use of pesticides is fundamentally reduced, the pesticide residue problem is effectively solved and the product safety and export quality of the Chinese wolfberry are significantly improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to the application of agricultural ecological control, in particular to screened repellent plants capable of preventing and controlling wolfberry aphids, and a method for planting repellent plants in wolfberry gardens for preventing and controlling wolfberry aphids. Background technique [0002] Aphids are important agricultural pests. They damage more than 50 families and 350 species of field and greenhouse crops, and can transmit more than 100 plant viruses. Lycium barbarum aphids (Aphis sp.), commonly known as honey bugs, putty insects, drought insects, etc., belong to the order Homoptera and are agricultural pests of the family Aphididae. Lycium barbarum aphids harm the flower organs and young fruits of the leaves of Lycium barbarum, making the shoots shrink and the flowers and fruits become smaller, which seriously affects the yield and quality of Lycium barbarum. Lycium barb...
