Embodiment 1

[0015] This example provides the preparation process and GC-MS test of Artemisia annua essential oil.

[0016] The aerial parts of Artemisia chinensis plants were naturally dried in the shade, pulverized, weighed 500g and placed in an essential oil extractor, extracted by steam distillation, and the distillation time was 6h. The distillate was extracted with n-hexane to obtain a n-hexane layer, anhydrous sodium sulfate was added to remove water, after concentration, the volume was measured, the essential oil was put into a dry glass bottle, and placed in a 4°C refrigerator for storage, that is, the North China Rice Artemisia essential oil.

[0017] The essential oil samples of Artemisia annua were analyzed by GC-MS. The test conditions were: GCMS-QP2010plus (Shimadzu); chromatographic column: DB-5MS (60m×0.25μm×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...

Embodiment 2

[0027] This example provides the determination of the contact killing activity of Artemisia annua essential oil on cotton aphid and psyllid.

[0028] (1) Determination of contact killing activity of Artemisia annua essential oil on cotton aphid

[0029] The insecticidal activity was determined by the leaf disc method. Polytetrafluoroethylene was applied to the four walls of a 12-well plate. After drying, the agar was spread on the bottom of the plate. Fresh cotton leaves without pesticides were taken, and the leaves were punched to make a A circular leaf disc with a diameter of 3cm, the leaves are soaked in medicine for 10s, then air-dried and placed in the orifice plate, inserted with 10 wolfberry cotton aphids, and placed in a light / dark=16h / 8h, 25℃, humidity of 60%~70% in the incubator. Negative and positive controls were used without the addition of Artemisia annua essential oil solvent and pyrethrin. Each treatment was repeated 6 times, with 10 cotton aphids per repetit...

Abstract

The invention discloses insecticidal Artemisia giraldii Pamp. essential oil which is prepared by the steps of naturally drying the overground part of an Artemisia giraldii Pamp. plant in the shade, crushing, weighing, putting into an essential oil extractor, extracting for 6 hours by adopting a steam distillation method, extracting by adopting normal hexane to obtain a normal hexane layer, and adding anhydrous sodium sulfate to remove water. The invention also provides an application of the Artemisia giraldii Pamp. essential oil in insect killing. The Artemisia giraldii Pamp. essential oil can effectively realize contact killing of cotton aphids and phylloxera.

Description

technical field [0001] The invention belongs to the technical field of botanical pesticides, relates to a Compositae, and in particular relates to an insecticidal Artemisia annua essential oil and application thereof. Background technique [0002] Psyllids and cotton aphid are common pests on citrus. These pests usually gather on the branches, leaves or fruits of citrus and harm by sucking sap, causing citrus branches withered, fallen leaves and fruit drop, and can produce secretions and induce soot sick. Among them, the citrus psyllid is the only natural transmission vector of citrus Huanglongbing which is the most difficult and most threatening in citrus production. At present, the control of these pests is still dominated by chemical pesticides. However, the frequent use of chemical pesticides brings about increasingly serious problems such as drug resistance, environmental pollution and pesticide residues. With people's attention to the ecological environment, food saf...
