Abstract
The present invention relates to ascarid glucoside △ C8 in prevention and treatment Monochamus alternatus and to stop the application in Bursaphelenchus xylophilus propagation.The method provided by the present invention that ascarid glucoside △ C8 is used for Monochamus alternatus prevention and treatment are as follows: ascarid glucoside △ C8 is placed in the pine tree containing alternatus Larva.Method provided by the invention is administered using in the pine tree of woodland Monochamus alternatus and infection Bursaphelenchus xylophilus.It can solve the problems, such as the Monochamus alternatus population quantity of pine wilt disease spot is big, harm weight and Bursaphelenchus xylophilus are spread rapidly by Monochamus alternatus.
Description
Technical field
The present invention relates to ascarid glucoside △ C8 to prevent and treat and stop the application in Bursaphelenchus xylophilus propagation in Monochamus alternatus.
Background technique
Pine nematode, referred to as " cancer " of pine tree are the most forest diseases of risk in the world, are pinaceae plants
Crushing epidemic disease, host plant infects this, and 2-March can be dead after being ill, can destroy within 3-5 years full wafer pine forest, harmfulness pole
By force.China from nineteen eighty-two since Nanjing finds pine nematode for the first time, epidemic situation diffusion rapidly, spread to including Jiangsu, Anhui,
14 provinces and cities such as Guangdong, Guangxi, Zhejiang, Fujian, Shanghai, Chongqing, Hubei, Shandong, 86 counties and cities.Over 28 years, add up lethal pine
More than 500,000,000 plants are set, more than 500 ten thousand mu of pine forest is destroyed, causes the economic loss of hundreds billion of members, and occurrence scope is also expanding year by year.
It not only brings about great losses to national economy, also destroys natural landscape and ecological environment, to China's pine forest resource abundant
It constitutes and seriously threatens.The harmful destructiveness of being critically ill is: pathogenicity is strong, and host's death rate is fast；Propagate it is fast, and usually it is sudden not
And it is anti-；Once occurring, difficulty of governance is big.Currently, pine nematode is relied primarily on and removes all sick trees to be administered, but
Because the particularity of its cause of disease life cycle, effect are unobvious.Therefore, it is suitable for from Infection cycie and diffusion mechanism set off in search
Control method becomes the task of top priority.
The cause of disease of pine nematode is Bursaphelenchus xylophilus, is one of most important Alien invasive species in China.It can not itself be complete
At Spreading and diffusion task, the Spreading and diffusion between pine tree must be completed by the carrying of insect vector Monochamus alternatus.Song Mo
Longicorn occurs and few in the non-generating region of Bursaphelenchus xylophilus, and harm is not enough to attract people's attention.After Bursaphelenchus xylophilus intrudes into China,
Interaction is cooperateed with medium Monochamus alternatus, the population density of the two all greatly improves, and forms expansion and spreads rapid trend.Woodland pine
The first disease time of material nematodiasis generally at the beginning of 6 months, 7, August part be pine nematode onset peak.By Infection of Bursaphelenchus xylophilus
Pine tree be place that Monochamus alternatus likes oviposition.The month in coming year 1-5, Bursaphelenchus xylophilus enter diapause, form diffused pine line
Worm.Husking forms diffused third-instar larvae (L firstⅢ), and be gathered in around Monochamus alternatus pupa room, June is with Monochamus alternatus
Sprout wings and forms diffused four-age larva (LⅣ) and be carried into Monochamus alternatus stomata and travel to new healthy pine tree, start new
The Infection cycie of one wheel.LⅣEnter resin canal by wound caused on bark when Monochamus alternatus Hope feeding or oviposition, then
Husking forms adult, lays eggs after these female, male imago matings, becomes reproduction type pine wood nematode after egg hatching and mass propagation and make
Pine tree withers to turn yellow quickly becomes the object of Monochamus alternatus oviposition again, and the alternatus Larva of spawning and hatching enters pine line again
Feeding burrow in parasitosis tree, forms pupa room.The two cooperation provides required condition, and utilization pair the completion history of life for other side
The condition just created completes itself development.In short, diffused four-age larva (LⅣ) formed time and Monochamus alternatus emergence time
To agree be the key that Bursaphelenchus xylophilus is carried propagation.Stop to the diffusive transport of Bursaphelenchus xylophilus is prevention and control Bursaphelenchus xylophilus
It is crucial.Therefore, the development of alternatus Larva is interfered and is regulated and controled, Monochamus alternatus emergence time can be postponed or nothing
Method is sprouted wings, to make LⅣIt can not form and cut off the approach of its Spreading and diffusion.
Summary of the invention
In order to realize the obstruction to Monochamus alternatus prevention and treatment and pine nematode diffusive transport, the present invention provides a kind of new prevention and control
Method.

It is provided by the present invention that ascarid glucoside △ C8 is used for Monochamus alternatus prevention and treatment and stops the side that Bursaphelenchus xylophilus is propagated as optimization
Method are as follows: ascarid glucoside △ C8 is adsorbed in the carrier for having adsorptivity and slow release effect, which is placed in alternatus Larva
In pine tree.The carrier for having adsorptivity and slow release effect is silicon rubber chock plug.
It is provided by the present invention that ascarid glucoside △ C8 is used for Monochamus alternatus prevention and treatment and stops the side that Bursaphelenchus xylophilus is propagated as optimization
Method are as follows:
1), ascarid glucoside △ C8 and organic solvent are mixed, obtain mixed liquor；
2), 20 μ l of mixed liquor obtained by step 1) is contacted with the carrier for having adsorptivity and slow release effect, to organic solvent
After volatilization, which is placed in the pine tree containing alternatus Larva.
The organic solvent is selected from methanol, ethyl alcohol or ether.
It is provided by the present invention that ascarid glucoside △ C8 is used for Monochamus alternatus prevention and treatment and stops the side that Bursaphelenchus xylophilus is propagated as optimization
In method, the dosage of ascarid glucoside △ C8 are as follows: 150nM-150 μM/m3Pine tree body.
What the present invention was realized has the beneficial effect that:
Ascarid glucoside △ C8 of the present invention is artificial sintetics, and stable structure, chemical property is steady under normal temperature and pressure
It is fixed, it is nontoxic, it is free from environmental pollution.
It is provided by the present invention to be used to Monochamus alternatus prevention and treatment by ascarid glucoside △ C8 and stop the method that Bursaphelenchus xylophilus is propagated operate
Simply, application easy to spread.
It is provided by the present invention that ascarid glucoside △ C8 is used for Monochamus alternatus prevention and treatment and stops the method for Bursaphelenchus xylophilus propagation to pine
Black longicorn prevention and treatment and the control efficiency for stopping Bursaphelenchus xylophilus propagation are obvious.
