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
The present invention relates to a kind of insect attractant, more specifically relate to a kind of Monochamus alternatus Adults attractant.
Background technology
Pine nematode is a kind of destructive disease of pine tree, it can make the pine tree that is injured withered, dead rapidly because of the physiological lack of water, cause huge economy and Ecological Loss, therefore claimed again the cancer of pine tree, be considered to the No.1 forestry quarantine harmful organisms of China.At present, the pine nematode epidemic-stricken area of China has been extended to 12 provinces such as Jiangsu, Zhejiang, Anhui, pine forest resource to China consists of grave danger, and the diffusion of seeking effective method control or inhibition pine nematode spreads, and has been the pressing issues that face in producing.Monochamus alternatus Hope claims again Monochamus alternatus, is the main communication media of China's pine nematode, and this worm mainly behaviors such as taking food, lay eggs of the adult by carrying pine wood nematode is propagated this disease, and the control Monochamus alternatus Hope is to suppress the fundamental way that the pine nematode diffusion spreads.Utilizing attractant monitoring and control Monochamus alternatus Adults, is the measure of comparatively economic, effective in the current pine nematode prevention and control and environmental protection.
At present, the product type of Monochamus alternatus Hope attractant is comparatively various.The attractant of the developments such as Xiao Chun (application number: 200910094345) mainly formed by 60～80% turpentine oil, 16～24% ethanol, 2～10% benzyl carbinol, 2～6% terpineol etc.; Attractant (the application number: 200810028389) mainly formed by pure natural extract from pine needles and ethanol of Chen Jiwen development; The attractant of the developments such as Fan Jianting (application number: 201010577064) mainly formed by 95% australene and 40% acetaldehyde; The attractant of yellow brave equality development (application number: 200510028194) mainly formed by 25～35%(v/v) turpentine oil, 5～10%(v/v) australene, 5%～7%(v/v) nopinene, 5～8%(v/v) laurene, 5～12%(v/v) 3-carene, 5～10%(v/v) alpha-terpineol and 30～38%(v/v) absolute ethyl alcohols etc.Above-mentioned Monochamus alternatus Hope lures product mainly to have following defective: the constituent of (1) 4 kind of attractant all is to derive from plant extract, lures collection target specificity not strong, luring of Monochamus alternatus Hope is collected effect have limitation; Consumption is large during (2) 4 kinds of open-air practical applications of attractant, and use cost is higher; (3) except the attractant product of the developments such as Fan Jianting, the constituent of other 3 kinds of attractants is all very complicated, and active ingredient and the mechanism of action are all clear not.
Summary of the invention
In order to address the above problem, the invention provides that a kind of constituent is simple, cost is low, the significant Monochamus alternatus Adults attractant of effect.
The technical scheme that the present invention takes is as follows:
Monochamus alternatus Adults attractant of the present invention comprises a kind of artificial synthetic compound, its preparation method is as follows: add undecyl alcohol in flask, then slowly splash into the thionyl chloride of 2～3 times of undecyl alcohol volumes, stir, leave standstill 2～6 hours after, add the semi-saturation saline solution of undecyl alcohol volume more than 3 times, mix, separatory, the collected organic layer anhydrous sodium sulfate drying, the rotary evaporation desolventizing obtains A liquid; In another flask, add ethylene glycol, the amount that adds 0.4～0.6 gram sodium metal by every milliliter of ethylene glycol slowly adds sodium metal, 50～70 ℃ of lower continuous heatings 2～6 hours, be cooled to room temperature, drip the A liquid of 0.3～0.8 times of ethylene glycol volume in the flask, stirred 2～6 hours, be heated to again 50～70 ℃, stirred 2～8 hours, and then added the semi-saturation saline solution of ethylene glycol volume more than 5 times, the ether of the benzinum of ethylene glycol volume and 2～4 times of ethylene glycol volumes more than 5 times, vibration, separatory, collected organic layer, organic layer are concentrated after with anhydrous sodium sulfate drying, the compound that is manually synthesized.
Described attractant also comprises one or both in Volatiles of Pinus, the alcohol.
Described Volatiles of Pinus comprises turpentine oil.
Described attractant is comprised of artificial synthetic compound and turpentine oil, and the volume ratio of the two is 1:200-800.
More preferably, the by volume combination of 1:200,1:400 and 1:800 of artificial synthetic compound and 99% turpentine oil; Wherein artificial synthetic compound is main effect component, and turpentine oil is synergistic component.
Advantage of the present invention:
(1) the present invention preferably adopts artificial synthetic compound and turpentine oil combination, and Monochamus alternatus Hope is had higher attractive effect, can be used as the effective means of monitoring and control Monochamus alternatus Hope, suppresses and delay its spread in china of pine nematode;
(2) domestic existing Monochamus alternatus Hope attractant all derives from the volatile matter of host pine tree, and complicated component, and cost is higher; Of the present invention and attractant comprises artificial synthetic compound, and effective dose is few; Generally, this attractant composition is simple, and production cost is low, and safety and environmental protection lures worm efficient high, with the obvious advantage.
