preparation example Construction

[0064] 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: using the essential oil of Asteria chinensis as the active ingredient of the biological control agent.

[0065] In some embodiments, the essential oil of Asteria chinensis is the essential oil extracted from the aerial part of Asteria chinensis plant;

[0066] Preferably, the aerial part of the Asteria chinensis plant is extracted by steam distillation and then extracted;

[0067] Preferably, the extraction temperature of the steam distillation method is 70-120°C, preferably 100°C; the extraction time is 3-9h, preferably 6h;

[0068] Preferably, the extractant is n-hexane, and the extraction time is 2-6h, preferably 4h;

[0069] Preferably, the extracted n-hexane layer is dried and concentrated; preferably, the drying refers to removing the moisture of...

experiment example

[0086] Experimental example, preparation and verification of insecticidal effect of Aster wood essential oil of the present invention

[0087] 1. Plant essential oil preparation

[0088] Take the aboveground part of the plant of Asteria chinensis, dry it naturally in the shade, crush it, put it in a volatile oil extractor after weighing, and extract it by steam distillation. The extraction time is generally 6 hours, and extract it with n-hexane to obtain the n-hexane layer. Add Remove water with anhydrous sodium sulfate, concentrate, measure the volume, put the volatile oil into a dry glass bottle, and store it in a refrigerator at 4°C.

[0089] 2. GC-MS test

[0090] 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℃;...

Abstract

The invention relates to application of Asterothamnus centrali-asiaticus in biological prevention and control, a biological prevention and control medicament and a preparation method of the biological prevention and control medicament, and belongs to the field of biological prevention and control. The invention provides application of Asterothamnus centrali-asiaticus in the field of biological prevention and control, and further provides a biological prevention and control medicament based on the application. The biological prevention and control medicament comprises an active ingredient, wherein the active ingredient comprises Asterothamnus centrali-asiaticus essential oil. Aphis gossypii, Frankliniella occidentalis or phylloxera can be efficiently killed by utilizing the new application of the Asterothamnus centrali-asiaticus or adopting the insecticide / insecticidal method provided by the invention, and the Asterothamnus centrali-asiaticus is a wild plant, is wide in distribution range, is simple and easy to obtain, is low in cost and is 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 central Asian aster wood in biological control, as well as its biological control agent and preparation method. Background technique [0002] Central Asian aster wood, scientific name: Asterothamnus centrali-asiaticus, is a plant of the Asteraceae genus. The plant is distributed in Mongolia and Inner Mongolia, Qinghai, Ningxia, Gansu and other places in mainland China. It grows in areas with an altitude of 1,300 meters to 3,900 meters, and generally grows in grasslands and desert areas. [0003] 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 f...
