Embodiment 1

[0031] Embodiment 1 Liaoshixin volatile oil extract preparation

[0032] Liao Asarum medicinal material (screened to remove sediment) is cut into pieces, 250g is put into a distillation flask, soaked in water for 1 hour, heated at about 100v to boil and distilled for 5 hours to obtain a distillation solution, and the precipitated essential oil part is separated with a separatory funnel, and packed into an essential oil bottle. About 3ml of essential oil can be obtained per 500g of Liaoshixin original drug, and each 6ml of essential oil can be used as an experimental sample.

Embodiment 2

[0033] Example 2 Preliminary Identification of Compounds in Liao Asarum Volatile Oil Extract

[0034] 1. GC-MS analysis

[0035] GC-MS analysis conditions use gas chromatography-mass spectrometry for Agilent7890B-5977A.

[0036]1. Chromatographic conditions: Chromatographic column: Agilent 19091s-433HP-5MS, 5% benzyl polysiloxane elastic quartz capillary column (30m×250μm 0.25μm); inlet temperature is 260°C; temperature program: initial temperature 70°C, maintain 0min, then rise to 75°C at 1°C·min-1, maintain for 5min; then rise to 107°C at 8°C·min-1, maintain 0min; continue to rise to 125°C at 50°C·min-1 , maintained for 5 minutes; then raised to 160°C at 10°C·min-1 and maintained for 3 minutes; finally raised to 240°C at 8°C·min-1 and maintained for 4 minutes. Carrier gas: He, flow rate 30mL·min-1, split ratio 20:1, injection volume 1μL, Gassaver: off.

[0037] 2. Mass spectrometry conditions: interface temperature: 260°C, ionization method: EI, electron energy: 70eV, ion...

Embodiment 3

[0051] The fresh-keeping boxes of the test group and the control group were placed separately at each test point for 5 days, and the two fresh-keeping boxes were adjacent to each other. After 5 days, record and count the Bactrocera dorsalis quantity (seeing table 2) that lures in each fresh-keeping box.

Abstract

The invention discloses application of asarum heterotropoides volatile oil extract as a bactrocera dorsalis attractant, the bactrocera dorsalis attractant, a preparation method thereof, and a method for preventing and controlling bactrocera dorsalis. Volatile substance essential oil components of the traditional Chinese medicine, asarum heterotropoides, are extracted by using a water distillationmethod; then, the attractant is directly used for attracting bactrocera dorsalis; wherein the effect is equivalent to that of a key recommended product, Cong Lv bactrocera dorsalis bait, of a currentnational peach industry system. The attractant can effectively attract the female adult citrus fruit flies and the male adult citrus fruit flies to eat, wherein a specially-designed insect attractingdevice is used for attracting the adult citrus fruit flies, so that damage caused by egg laying of the female citrus fruit flies can be remarkably reduced, the purpose of effective prevention and control is achieved, and the attractant is efficient, free of pollution and residues and beneficial to ecological environment protection and sustainable development.

Description

technical field [0001] The invention relates to the application of Liaoshixin volatile oil extract as an attractant for Bactrocera dorsalis, a Bactrocera dorsalis attractant and a preparation method thereof, and a method for preventing and controlling Bactrocera dorsalis. Background technique [0002] Bactrocera dorsalis is a worldwide pest of Diptera Tephritidae. The insect has a wide range of hosts and can be widely parasitic on more than 250 kinds of fruit trees and crops. Mainly through adults laying eggs on the fruit, the hatched larvae damage the fresh pulp in the fruit, resulting in local softening of the pulp tissue, the larvae eat the pulp, and secondary microorganisms infect the fruit tissue, resulting in fruit rot and fruit drop, seriously affecting the quality of the fruit And output, brought huge loss to the agricultural production of our country. Because the insect is difficult to control, has strong fecundity, short development cycle, and serious generation ...
