Abstract
An efficient sex attractant for killing scholartree olethreutidae which is dangerous to growth and development of Chinese scholartree and pagoda tree contains such components as (E, E) -8.10 -dodecadien -1 -alcohol (10-90%), (E, E) -8, 10 -dodecadien y1 acetate (90-10%) and 2, 6 -ditertbutyl p -cresol (appropriate), and features high attraction and killing action to scholartree olethreutidae and no environmental pollution.
Description
What the present invention relates to is that a kind of scholartree olethreutree that grows with trapping harm Chinese scholartree and Chinese pagoda tree is the efficient sex attractant for scholartree olethreutree of purpose.
Scholartree olethreutree (Cydia tradias Meyyick), also cry the Chinese scholar tree petiole little moth, it is one of important pests of harm Chinese scholar tree and Chinese pagoda tree, in Beijing, all there is distribution on ground such as Tianjin, Hebei, Shanxi, Shaanxi, Gansu, in 2-3 generation, took place in 1 year in scholartree olethreutree, larva eats into into branch from the base portion of Chinese scholartree winglike compound leaf, cause petiole and spray withered with hang, weight person's tree crown is bald, and the lighter's branch fractures slightly, has a strong impact on growing and viewing and admiring of trees.Prevented and treated scholartree olethreutree mainly by spraying chemical pesticide in the past.Because this insect is taken place from generation to generation many, the time is long, is again borer pest, and larva goes into the branch or the Fructus Sophorae once hatching the very fast moth that comes out, and sprays chemical pesticide, poor effect.And most of Chinese scholar trees are grown in before and after avenue both sides and the resident house, spray chemical pesticide, cause environmental pollution, and therefore the harm people's health is badly in need of a kind of new way of efficient, nontoxic, free of contamination control scholartree olethreutree harm.
Can have the trace level chemical substance of special odor after many insects reach maturity to vitro release, before luring different in nature insect of the same race, go mating.This chemical substance that plays the communication effect in the insect mating process is insect sex pheromone, or sex pheromone.Usually be the insect sex attractant during with the sex pheromone of synthetic or analog pest control, the abbreviation gyplure.
It with sex pheromone or gyplure pest control the new technology of a kind of pest control of growing up in recent years, existing hundreds of insect sex attractants are used both at home and abroad, but there is no the report of relevant scholartree olethreutree sex pheromone so far, though the existing codling moth sex pheromone (E that reports, E)-8,10-12 carbon diene-1-alcohol has attracting action to state's scholartree olethreutree, but because composition is single, lure the moth activity not high, do not have the purpose of control state scholartree olethreutree harm.
The object of the present invention is to provide of the harm of a kind of state scholartree olethreutree, the blank of filler control scholartree olethreutree harm to Chinese scholar tree and Chinese pagoda tree.
Embodiment of the present invention are to release by the scholartree olethreutree sex pheromone is broken, and use a kind of efficient sex attractant for scholartree olethreutree of bionics techniques synthetic, and it forms component and the set of dispense ratio is:
(E, E)-8,10-12 carbon diene-1-alcohol 10-90%
(E, E)-8,10-12 carbon diene yl acetate 90-10%
2, the 6-BHT is an amount of
(E in the said components, E)-8, pure and mild (the E of 10-12 carbon diene-1-, E)-8,10-12 carbon diene yl acetates are the Main Ingredients and Appearance of scholartree olethreutree sex pheromone, the core that lures that will contain this gyplure in scholartree olethreutree adult mating season is placed on Chinese scholar tree or the Chinese pagoda tree branch, just can lure male worm effectively so that catch and kill.In the component 2; the 6-BHT is the anti-oxidant protective agent of above-mentioned two components; to guarantee the activity of gyplure; and prolonging its active timeliness phase so that more effective luring catched and killed scholartree olethreutree to reach the purpose of high-efficiency prevention and control scholartree olethreutree harm, its content generally is controlled to be 5% of gyplure total amount.
Luring core is the carrier of gyplure, and special rubber stopper is cleaned, airing, the scholartree olethreutree gyplure is dissolved in ether, releases desired concn with benzinum alkene again, with syringe the gyplure of required dosage is splashed into the recess of rubber stopper, after the solvent evaporates lure core.
Trapper is by luring core and insect trap two parts to form.Insect trap surrounds with plastic made tile rib plate, and two ends are triangular in shape, and insect trap is gone to the bottom and followed closely a waxed cardboard that scribbles insect sticker, will lure core to be through on the iron wire, hangs down in the middle of last rib, apart from the about 2cm of glue face.Trapper is hung on the Chinese scholartree side shoot, and overhead about 2m at a distance of more than the 10m, carries out the woodland trapping test between two trappers.
Woodland trapping test result shows that efficient sex attractant for scholartree olethreutree provided by the invention has strong attracting action to scholartree olethreutree, and the variation of induced moth number can reflect the growth and decline situation of woodland scholartree olethreutree adult in time, exactly.Scholartree olethreutree has three adult peak of occurrence in the Beijing area, the winter generation adult beginning sees mid or late May, is peak of occurrence at the beginning of 6 months by the end of May.First generation moth amount is less, and the peak period is in mid-July, second generation moth amount showed increased, and the moth peak appeared at by the end of August at the beginning of 9 months.After each moth peak, all occur being bored moth and withered branch and the leatherleaf that fractures 8, also have some Fructuss Sophorae because of by the blackening of drying up of damaging by worms September on the Chinese scholar tree tree crown by the scholartree olethreutree larva.
Application of the present invention and effect are as follows:
1. monitor the scholartree olethreutree insect pest situation: generation and the growth and decline situation that can in time and exactly understand the woodland scholartree olethreutree with the detecting and reporting pest information of efficient sex attractant for scholartree olethreutree work provided by the invention, provide scientific basis for prevent and treat effectively in good time, it is highly sensitive that this high-efficient inducer observes and predicts method, selectivity is strong, easy to use, expense is cheap, is suitable for generally applying.
2. mass trapping: detect the adult that draws according to insect pest situation curve takes place, the trapper that contains efficient scholartree olethreutree gyplure provided by the invention in the peak period dispensing of adult moth amount, the male worm of the mating of seeking a spouse is is in time trapped and killed, made female worm lose the mating machine meeting, can not raise up seed effectively and endanger.
3. interference mating: discharge the mating that this gyplure can disturb the scholartree olethreutree male and female effectively, also this gyplure and chemosterilants, virus, bacterium etc. can be used, with gyplure male worm is lured, it is contacted with apholate, virus, bacterium etc., fly away then, go to contact with other insect, mating, it is more much bigger than catching and killing then and there like this its population to be caused damage.
In sum; no matter efficient sex attractant for scholartree olethreutree provided by the invention is used for detecting and reporting pest information or directly prevents and treats the scholartree olethreutree insect pest with mass trapping and interference mating method; all help protecting natural enemy; Xing Yi removes the evil; give full play to the power of integrated control, improve control efficiency, avoid using chemical pesticide in addition and can reduce pollution; the protection environment, social benefit and ecological benefits are remarkable.
