Said invention not only has high attraction activity, but also does not contaminate environment, and its cost is low.
Description
Technical field
The invention belongs to the nuisanceless improvement of forest substantial risk epidemic disease evil field, utilize plant information compound (attractant) that pine wood nematode vector insect-Monochamus alternatus Hope is carried out a kind of efficient attractant and the application thereof that chemical ecology regulation and control is administered specifically
Background technology
Monochamus alternatus Hope (Monochamus alternatus Hope) is the important trunk borer of China south pine forest, to the east of China is distributed in Tibet, on the south the Hebei, to the east of Taiwan, reach Guangdong in the south.But the destructive of it mainly is that also it is the vector insect of pine nematode, this disease in China and Japan mainly by the Monochamus alternatus Hope adult after sprouting wings when supplementing the nutrients and laying eggs, nematode in the longicorn body is got food by longicorn or the healthy tree of wound intrusion of causing that lays eggs causes pine death, pine forest is caused crushing harm, be described as " cancer of pine tree ".This disease has that harm is serious, pathogenicity sets by force, extremely that speed is fast, difficulty of governance is big, the route of transmission is many, the wide several big characteristics in territory, normal region.In a single day pine tree infects pine nematode, just can be dead in 40 days; And should disease also can cause disaster by rapid spread, cause large stretch of pine forest withered.Pine wood nematode (Bursaphelenchus xylophilus) has become one of external pest that China is had the greatest impact, belongs to the international quarantine object, is distributed in states such as Japan, Korea S, the U.S., Canada, Mexico and Portugal abroad.China finds pine wood nematode after being ill from nineteen eighty-two first in the Zhongshan Tomb, Nanjing, in Jiangsu, province (district) area such as Anhui, Hong Kong, Guangdong, Zhejiang, Shandong, Taiwan and Hong Kong takes place in succession.At present, pine wood nematode has been diffused into 86 counties and cities, 10 provinces and regions, area takes place reach 8.7 ten thousand hm
2, deadly pine tree more than 3,500 ten thousand strains of accumulative total, direct economic loss has reached 2,500,000,000 yuan, 25,000,000,000 yuan of indirect losses.In recent years, the epidemic situation diffusion spreads the gesture that is aggravation, and present pine material nematode infected offset has only 67 kilometers from Mt. Huangshan Scenic Area air line distance, and famous scenic spot such as Mount Huang, world's natural culture legacy and emphasis ecological zone are constituted huge threat.Country has paid huge cost to the control of pine nematode, and only state revenue and expenditure in 2000 is used to prevent and treat the direct funds of pine nematode just up to 1,000 ten thousand yuan.
Pine tree is the chief species of China, and area accounts for 58% of whole softwood forest.The existence of pine genus plant all can be seen in nearly all forest zone from the Plain to the high mountain.In these pine genus plants, numerous species is the sense patient of pine wood nematode.China has the popular environmental condition of suitable pine nematode.According to discovering, Hainan of China, Guangdong, Guangxi, Fujian, Taiwan, Zhejiang, Jiangxi, Yunnan, Guizhou, Sichuan, Hunan, Hubei, Jiangsu, Anhui, Henan, Shaanxi, Shandong, Hebei, Shanxi, Beijing, Shanghai, Tianjin, Hong Kong are the normal region of pine wood nematode, and the some areas in Liaoning, Xinjiang, Tibet, Gansu also are fit to the generation of pine wood nematode.Therefore, if can not effectively contain the propagation of pine nematode,, bring the economic loss that to estimate with the ecocatastrophe that initiation is difficult to contain.In addition, pine wood nematode has become the excuse of some country's restriction Chinese commodity outlets, manufacturing trade friction as technology barriers.Calendar year 2001, the restriction that European Union exports China's timber package begins emphasis and transfers to pine wood nematode, and level and the dynamics of China control pine wood nematode will directly have influence on the international trade of China.Therefore, the pine wood nematode control technology is the important topic that is related to national politics, economy, social development and ecological safety.
Studies show that in a large number in the triangular system of pine tree-Monochamus alternatus Hope-pine wood nematode, the vector insect Monochamus alternatus Hope is the pathogenetic essential condition of pine wood nematode, if can effectively control Monochamus alternatus Hope, just can reach the purpose that effective containment pine nematode diffusion spreads.(2000) (Takasu F such as Japan scholar Takasu, Yamamoto N, Kawasaki K et al., 2000.Modeling the expansion ofan introduced tree disease, Biological Invasions vol.2, No.2:141-150) report, in case Monochamus alternatus Hope density drops to one below the threshold value, infecting of pine wood nematode just can not cause the death of pine tree, and along with the reduction of longicorn population density, this sick diffusion velocity will obviously descend.
At present, the major measure of control Monochamus alternatus Hope is used chemical insecticide, biological control, physical control and trapping etc.Chemistry wipe out and treat insect pests and plant diseases mainly be spray in the adult stage chemical pesticide and larval phase sick material the medicament fumigation, but the longicorn adult eclosion phase is long and the disguise of larva harm, wipes out and treat insect pests and plant diseases DeGrain, a large amount of dispensers are serious environment pollution also.Biological control mainly is to utilize the control to Monochamus alternatus Hope of parasitism, predator insect and natural enemy microbe.Because biological control is affected by environment bigger, and the pathogenic cycle is long, control efficiency is also not ideal.Physical control mainly is methods such as burning, fumigation, heat baking, section making beating and saw plate that the tree that dies of illness of cleaning is concentrated, but this method is passive reply.Mass trapping is according to Monochamus alternatus Hope the taxis of host plant smell to be reached the purpose of trapping, and this method is not only the effective means of insect pest situation and prognosis forecast, and a large amount of trapping can effectively reduce insect density, thereby can effectively contain the harm of pine nematode.
Luring of pine tree volatile materials mainly leaned in Monochamus alternatus Hope location to the host when getting food and laying eggs, and the main component of these volatile materials is the mixture of monoterpene and lonely property fermentation product.In recent years, domestic and international gloomy guarantor worker utilizes these active substances to be mixed with multiple attractant, at the prediction of pine nematode, reduces the longicorn population quantity, and the harm that alleviates the pine nematode in next year obtains certain effect.The Zhao Jin of Subtropical Zone Forestry Inst., Chinese Academy of Forest Science etc. (Monochamus alternatus attractant and attracting action research. forest-science, 2000,3:262-267) at the Wang Yu Yan, on the basis of research such as Zhang Lianqin, select monoterpene for use, rosin, turpentine oil, ethanol, isopropyl alcohol, acetaldehyde, acetone, benzoic acid, Ground Cloves and synergist etc. are mixed with a plurality of prescriptions in different component and ratio, filter out the attractant M99-1 the strongest by research to the Monochamus alternatus Hope attractive activity, its main component is by monoterpene, acetaldehyde, acetone and organic solvent are formulated, the making that lures core is that the discarded pop can that opening is less is cleaned, built-in absorbent cotton, the 140ml attractant that injection prepares is promptly made and is lured core, and its attractive activity is higher than domestic other attractant and Japanese attractant " ホ ボ ロ Application ニ ".At present, 56 counties (city) and unit use attractant M99-1 in Zhejiang Province, and extended to 12 provinces (city, district) such as Hubei, Sichuan, Guangdong, Guangxi, Guizhou, Hunan, Fujian, Liaoning, Jilin, Shanghai, Jiangsu and Anhui, be widely used at home in the control of pine wood nematode and medium insect Monochamus alternatus Hope.But, attractant M99-1 at the phase attractant effect that supplements the nutrients, lure core to continue to lure time, product cost and to reduce aspects such as labour all far away apart from practicability.In addition, in actual applications, attractant not only lures efficient low, and is that attractant is added in the less pop can of opening, and jar built-in absorbent cotton injects promptly to become behind the attractant and lures core.The evaporation rate of attractant is not effectively controlled in the core owing to luring, lure the cycle short, the Dispensable continuous time of luring shortly has only 7-10 days, and needs constantly to add attractant, cost height not only, and bring great inconvenience for the woodland practical operation of circumstance complication; This product of what is more important is better to the Monochamus alternatus Hope attracting action in egg-laying period, and very low to the Monochamus alternatus Hope attractive activity of the phase that supplements the nutrients.The female adult worm that attractant M99-1 traps is all cherished ovum, the average fish brood amount of every female adult worm is 15.9, wherein the yellow-white mature egg is 12.3, and 3.6 of yellow or faint yellow immature eggs illustrate that the female adult worm that M99-1 traps all is that the ripe adult more than 1 time is crossed in process extra-nutrition and mating.Yet, it is that the tonic of getting that is accompanied by Monochamus alternatus Hope is filled trophogenic that pine wood nematode is invaded in the host pine tree body, after the Monochamus alternatus Hope adult eclosion portals, be diffused into tree crown top gets food living branch bark supplemented the nutrients to 3 years then by creeping and circling in the air, propagate nematode simultaneously, adult supplements the nutrients to be needed to carry out mate and oviposit through 2-3 Zhou Houcai.So M99-1 is very low even do not have to the longicorn attractive activity of the phase that supplements the nutrients.
Summary of the invention
The objective of the invention is provides a kind of highly active Monochamus alternatus Hope attractant and application method thereof for the effectively propagation of containment pine nematode.Attractant of the present invention is with several Monochamus alternatus Hope to be had after highly active pine tree volatile matter solvent and synergist prepare by a certain percentage, packs into to have the luring in the core bottle of slow releasing function, makes and lures core.This lures core not only the Monochamus alternatus Hope in egg-laying period to be had good attracting action, and the Monochamus alternatus Hope of the phase that supplements the nutrients also there is good attracting action, after will luring core to insert trapper, be suspended on ventilation or border in the pine forest, the 120ml slowly-releasing lures its rate of release appropriateness of core, the cycle that once continues to lure can reach more than 1 month, by mass trapping Monochamus alternatus Hope adult, reached its spread in china of effective reduction insect density and containment pine nematode.The present invention is achieved in that it is after being mixed by a certain percentage by several high activity pine tree volatile matter reagent and synergist that attractant of the present invention lures core, pack into and have luring of slow releasing function and (purchase in the core bottle in three one-tenth plastic molding and processing plants of Shanxi province Taiyuan city, volume is 120mL or 200mL), promptly make the Monochamus alternatus Hope attractant and lure core.The efficient attractant of Monochamus alternatus Hope that the present invention proposes it contain 25%-35% (v/v) turpentine oil (Turpentine) with 26%-34% for well, add 5%-10% (v/v) australene (R-α-Pinene) with 7%-10% for well, add 5%-7% (v/v) nopinene (β-Pinene) with 6%-7% for well, add 5%-8% (v/v) laurene (Myrcene) with 5%-7% for well, add 5%-12% (v/v) carene ((3)-Carene) with 7%-9% for well, add 5%-10% (v/v) alpha-terpineol (α-Terpineol) with 7%-9% for well, add 30%-38% (v/v) absolute ethyl alcohol with 33%-35% for well, (wherein carene is available from Beijing big chemical industry instrument of easypro uncle Co., Ltd, and all the other are available from Chemical Reagent Co., Ltd., Sinopharm Group).With 7 kinds of compounds by volume percentage evenly mix, the attractant for preparing be respectively charged into have the luring in the core bottle of slow releasing function, tighten bottle cap, promptly make the core that lures of the efficient attractant of Monochamus alternatus Hope.The present invention is made the core that lures of the efficient attractant of Monochamus alternatus Hope, Ma02, with the M99-1 attractant of Zhao Jinnian development lure core in contrast, trap comparative trial in forest farm, Mt.
