preparation example Construction

[0051] The examples in this group provide a method for preparing a biological control agent. All the examples in this group have the following common features: the preparation method of the biological control agent comprises: extracting essential oil from S. chinensis.

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

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

[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 extraction agent 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; the concentration refers to that the dried p...

experiment example

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

[0060] 1. Preparation of plant essential oils

[0061] The roots of Nanmuxiang plants were naturally dried in the shade, pulverized, placed in a volatile oil extractor after weighing, and extracted by steam distillation. The extraction time was generally 6h, and n-hexane was used for extraction to obtain a n-hexane layer, and anhydrous sulfuric acid was added. Sodium to remove water, after concentration, measure the volume, put the volatile oil into a dry glass bottle, and store it in a 4°C refrigerator.

[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℃-10 ℃ / min-300℃-20min; split ratio: 30:1; constant linear velocity mode: 30cm / sec; carrier gas: He...

Abstract

The invention "the application of Aristolochiayunnanensis Franch. in biological control and its biological control agent and preparation method" belongs to the field of biological control. The present invention provides the use of Aristolochiayunnanensis Franch. in the field of biological control, and based on the use, the present invention further provides a biological control agent, which includes an active ingredient; the active ingredient includes Aristolochia essential oil. Utilizing the new application of Aristolochiayunnanensis Franch. of the present invention or adopting the insecticide / insecticide method of the present invention can efficiently kill Western flower thrips or psyllids, and Aristolochia is a wild plant with a wide range of distribution and is easy to obtain , low cost, 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, a biological control agent and a preparation method thereof. Background technique [0002] Psyllids are an important group of insects in the order Homoptera. It is also the general name for the Homoptera Psyllid family. For the gradual change of insects, individual development through three stages of egg, nymph and adult. Mouthparts piercing. Adults are small, lively and jumpy. The nymphs are round and flat, covered with waxy secretions. Most of them are harmful to woody plants, and the most important ones are the pear psyllium that harms pear trees and the mulberry psyllium that harms mulberry trees. [0003] Western flower thrips are a class of animals in the Thripidae family. Also called alfalfa thrips, it belongs to the order Thysanoptera. Western flower thrips have a mixed diet, wit...
