Embodiment 1

[0015] 1. Preparation of artificially synthesized complexes

[0016] Add 5 ml of undecanol to the flask, then slowly drop in 10 ml of thionyl chloride, stir, and after standing for 2 hours, add 15 ml of semi-saturated saline, mix, separate the layers, collect the organic layer, and use anhydrous Dry over sodium sulfate, and then remove the solvent with a rotary evaporator to obtain liquid A. Add 10 ml of ethylene glycol to another flask, then slowly add 6 grams of sodium metal, continue heating at 60 °C for 6 hours, cool to room temperature, add 6 ml of A solution to the flask, stir for 2 hours, and heat to 60 °C Stirring was continued for 6 hours, and then a mixed solution of 80 ml semi-saturated saline, 80 ml petroleum ether and 30 ml diethyl ether was added, shaken, separated, and the organic layer was collected. The organic layer was dried over anhydrous sodium sulfate and concentrated to obtain the synthetic compound. The prepared compound was used to carry out the ante...

Embodiment 2

[0036] A kind of synthetic compound of the present invention, its preparation method is as follows:

[0037] Add 50 ml of undecyl alcohol in the flask, then slowly drop into 150 ml of thionyl chloride, stir, and after standing for 3 hours, add 300 ml of semi-saturated saline, mix, separate, collect the organic layer, and use Dry over anhydrous sodium sulfate, remove the solvent to obtain liquid A; add 30 ml of ethylene glycol to another flask, then add 12 grams of sodium metal, continue heating at 70 °C for 2 hours, cool to room temperature, and add dropwise to the flask 24 ml of liquid A, stirred for 5 hours, heated to 50 °C, stirred for 2 hours, then added 200 ml of semi-saturated saline, 200 ml of petroleum ether and 120 ml of diethyl ether, shaken, separated, collected the organic layer, and used anhydrous After drying over sodium sulfate and concentrating, synthetic compound 1 was obtained.

Embodiment 3

[0039] A kind of synthetic compound of the present invention, its preparation method is as follows:

[0040] Add 20 ml of undecanol to the flask, then slowly drop into 40 ml of thionyl chloride, stir, and after standing for 6 hours, add 200 ml of semi-saturated saline, mix, separate, collect the organic layer, and use Dry over sodium sulfate, remove the solvent to obtain liquid A; add 20 ml of ethylene glycol to another flask, then slowly add 8 grams of sodium metal, continue heating at 50 ° C for 6 hours, cool to room temperature, and drop 6 1 ml of liquid A, stirred for 2 hours, heated to 60 °C, stirred for 8 hours, then added 150 ml of semi-saturated saline, 100 ml of petroleum ether and 80 ml of diethyl ether, oscillated, separated, collected the organic layer, the organic layer After drying with anhydrous sodium sulfate and concentrating, synthetic compound 2 was obtained.

Abstract

The invention provides a Monochamus alternatus adult attractant. The Monochamus alternatus adult attractant comprises an artificially-synthesized compound, and the compound is prepared through adding reagents comprising undecyl alcohol, thionyl chloride, glycol, metallic sodium and the like. The Monochamus alternatus adult attractant comprises the artificially-synthesized compound, so the effective application amount is less; the Monochamus alternatus adult attractant has a high trapping effect on Monochamus alternatus, and can be used as an effective means for monitoring and controlling the Monochamus alternatus to inhibit and delay the propagation of the pine wilt disease; and the Monochamus alternatus adult attractant generally has the advantages of simple components, low production cost, safety, environmental protection, high insect trapping efficiency, and advantage obviousness.

Description

technical field [0001] The invention relates to an insect attractant, more specifically to an attractant for adult chrysalis monochamus. Background technique [0002] Pine wood nematode disease is a devastating disease of pine trees. It can cause the affected pine trees to wither and die rapidly due to physiological water shortage, causing huge economic and ecological losses. The number one forestry quarantine pest. At present, the epidemic area of ​​pine wood nematode in my country has expanded to 12 provinces including Jiangsu, Zhejiang, Anhui, etc., which poses a huge threat to the pine forest resources in my country. It has become an important task to find effective methods to control or inhibit the spread of pine wood nematode. urgent problems facing. Monochamus alternatus, also known as Monochamus alternatus, is the main vector of pine wood nematode disease in my country. The insect mainly transmits the disease through the behaviors of feeding and laying eggs of a...
