preparation example Construction

[0051] The embodiment of this group provides a preparation method of biological control agent. All the examples in this group have the following common features: the preparation method of the biological control agent includes: extracting the essential oil of nanmuxiang.

[0052] In a specific embodiment, said Nanmuxiang refers to the root of Aristolochia yunnanensis plant;

[0053] Preferably, the essential oil extraction refers to extracting by steam distillation and then extracting.

[0054] In some embodiments, the extraction temperature of the steam distillation method is 70-120°C, preferably 100°C; the extraction time is 2-8h, preferably 6h;

[0055] Preferably, the extractant is n-hexane, and the extraction time is 0.2-1h, preferably 0.5h;

[0056] Preferably, the extracted n-hexane layer is dried and concentrated; preferably, the drying refers to removing the moisture of the n-hexane layer with anhydrous sodium sulfate; Get Southernwood Essential Oil;

[0057] Prefe...

experiment example

[0059] Experimental example, the specific preparation process of the biological control agent of the present invention, component identification and effect verification

[0060] 1. Plant essential oil preparation

[0061] The root of the plant is naturally dried in the shade, crushed, weighed, placed in a volatile oil extractor, extracted by steam distillation, the extraction time is generally 6 hours, extracted with n-hexane to obtain the n-hexane layer, and added with anhydrous sulfuric acid Remove water from sodium, concentrate, measure the volume, put the volatile oil into a dry glass bottle, and store it in a refrigerator at 4°C.

[0062] 2. GC-MS test

[0063] The volatile oil samples were analyzed by GC-MS. The test conditions were: GCMS-QP2010 plus (Shimadzu); Chromatographic column: DB-5MS (60m×0.25um×0.32mm) (Agilent); Heating rate: 60°C-10 ℃ / min-300℃-20min; split ratio: 30:1; constant linear velocity mode: 30cm / sec; carrier gas: He; ion source temperature: 200℃; i...

Abstract

The invention relates to application of Aristolochia yunnanensis Franch in biological prevention and control, a biological prevention and control agent and a preparation method of the biological prevention and control agent, and belongs to the field of biological prevention and control. The invention provides application of Aristolochia yunnanensis Franch in the field of biological prevention and treatment, and further provides a biological prevention and treatment agent based on the application. The biological prevention and treatment agent comprises an active component, and the active component comprises Aristolochia yunnanensis Franch essential oil. By utilizing the new application of Aristolochia yunnanensis Franch or adopting the insecticide / insecticidal method, Frankliniella occidentalis or phylloxera can be efficiently killed. The Aristolochia yunnanensis Franch is a wild plant, is wide in distribution range, simple and easy to obtain, low in cost and suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of biological control, and in particular relates to the application of Aristolochiayunnanensis Franch. in biological control and its biological control agent and preparation method. Background technique [0002] Psyllids are an important group of insects in the order Homoptera. It is also the general term for the family Psyllididae of the order Homoptera. For gradual metamorphosis insects, individual development goes through three stages: egg, nymph and adult. Mouthparts piercing and sucking. Adults are small, lively and able to jump. Nymph body is round and flat, body surface is covered with waxy secretion. Most of them harm woody plants, the important ones are pear psyllids that harm pear trees and mulberry psyllids that harm mulberry trees. [0003] Western flower thrips is a genus of animals in the thrips family Thripidae. Also known as alfalfa thrips, it belongs to Thysanoptera. Western flower thrips has a...
