Abstract
The invention discloses a tea geometrid imago attractant and a preparation method of a lure with the attractant, belonging to the technical field of prevention and control of pests by means of large-quantity trap with the combination of information compounds and trappers. The attractant comprises the following ingredients in parts by weight: 0.5-40 parts of cis-3-hexene butyrate, 1.5-120 parts of benzyl alcohol, 0.5-240 parts of cis-3-olefine aldehyde, 0.001-0.2 part of 2,6-bitertiary butyl p-cresol and 0.001-0.2 part of 2-hydroxy-4-methoxy-benzophenone. The tea geometrid imago attractant disclosed by the invention is reasonable in compatibility of medicines, and can effectively trap, prevent and control tea geometrids; the tea geometrid imago attractant adopts a polyethylene sustained-release bottle, so that effective components can be slowly and uniformly released, and the lasting period is prolonged. Due to an antioxidant and an ultraviolet absorbent added into the tea geometrid imago attractant, the components of the attractant are effectively prevented from oxygenolysis by factors of external air, light, ultraviolet light and the like. Therefore, the attractant is a tea geometrid imago attractant with persistent effects.
Description
Technical field
The invention belongs to the means of carrying out mass trapping in conjunction with trapper by semiochemical and carry out the technical field of pest control, be specifically related to a kind of adults of ectropis obliqua attractant and lure core preparation method containing this attractant.
Background technology
Tea geometrid (
ectropis obliquaprout (=Boarmia obliqua hypulina Wehrli)), belong to Lepidoptera, Geometridae, is one of important Pests of Tea-Plants of China.In Jiangsu, the tea place in the province such as Zhejiang, Anhui, Fujian and Henan occurs serious.Except causing harm tea tree, the plants such as the cherry of still causing harm, pomegranate, Chinese ash and soybean.Belong to striped in field and assemble pattern of spatial distribution, in year generation 6-7 generation, generation overlap is serious, and egg laying amount is large, often a large amount of generation.When serious generation, can make branch stalk baldness, three tea, four tea can not be adopted, and tree vigo(u)r is weak and cold-hartliness is poor, is subject to freeze injury winter, after 2,3 years, could recover original output, tea tree can be eaten into polished rod and even directly cause tea tree death when rampant generation.Traditional means of prevention is to spray chemical pesticide, as decis, Biphenthrin and cypermethrin etc., but the frequent use of chemical pesticide has not only caused the residue of pesticide of tealeaves, more cause insect to develop immunity to drugs and the problem such as the large generation of secondary insect.In addition, (only within 2007, just having revised 227) day by day improved to the residual examination criteria of outlet tealeaves agriculture by European Union, more seriously the acute toxicity of China's a large amount of residue of pesticide such as 5a,6,9,9a-hexahydro-6,9-methano-2,4, Imidacloprid that use in the diseases and pests controlling of tea place has exceeded ARfD standard by disabled, and China's tea export must be subject to direct impact.In recent years, biopesticide is also applied in the control of tea geometrid larvae gradually as tea-geometrid-type polyhedrosis viruses preparation, matrine and bacillus thuringiensis,Bt (Bt) preparation etc., and especially in organic tea garden, application is more extensive.But above-mentioned biological agent is often subject to the impact of many factors on the field control effect of tea geometrid larvae, as best in tea geometrid virus formulation spray effect when the 1-2 age, tea geometrid is excessive completely invalid the length of time; Bacillus thuringiensis,Bt is short etc. in unstable and longevity of residure of the preventive effect performance in field.Therefore, in production, be badly in need of one simple to operate, and effective green Prevention Technique.
Utilize insect sex pheromone to carry out insect pest situation monitoring and start from the sixties in 20th century with control.Due to its have highly sensitive, safety non-toxic, specialization strong, to natural enemy and plurality of advantages the is plant protection work person's such as beneficial organism is safe, free from environmental pollution study hotspot always.There is expert to expect: utilizing the population density of semiochemical regulation and control insect is one of important means of 21 century control of insect.In recent years, tea geometrid increases gradually and has the trend spreading gradually at the generation area in the province such as Zhejiang, Jiangsu and Anhui.Therefore, the population monitoring of adults of ectropis obliqua and Study of Prevention Technology just seem particularly urgent and important.Tea geometrid is as one of important defoliator in tea place, and the separation of its sex pheromone, qualification and artificial synthesizing as far back as the eighties in last century just complete, and (Z is found in research, Z)-3,9-6,7-epoxy-18 carbon diene is the key component that causes the reaction of seeking a spouse, (Z, Z, Z)-3,6,9-22 carbon triolefin, (Z, Z, Z)-3,6,9-24 carbon triolefin and (Z, Z)-9,12-18 carbon two olefine aldehydrs are submembers.Regrettably, although the research of tea geometrid sex pheromone starting early, but existing pheromones composition lures collection effect undesirable to the field of adults of ectropis obliqua, even sometimes completely invalid, thereby directly caused current tea geometrid pheromones can not directly apply to the difficult situation of control and monitoring.In recent years, along with the continuous progress of modern chemical analysis technology and raw survey means, all many-sides such as the field application technology of plant volatile, the especially kind of insect pest inducing plant volatile matter, ecological functions and volatile matter have caused chemical ecological Studies person and plant protection work person's very big concern.The experimental results shows, host's volatile matter (after health or insect pest induction) can lure the natural enemy of plant-feed insect come predation or parasitic, attraction or repellent phytophagy insect, cause that the defence that closes on plant prepares.
The applicant has identified the tea geometrid larvae chemical constitution of 55 kinds of volatile matters that induction tea tree discharges that causes harm.Wherein, there are 17 kinds to there is tentaculum electric potential activity to adults of ectropis obliqua, and then the method for utilizing Y-shaped smell sensing apparatus filters out including 3 kinds of green leaf volatiles, 2 kinds of aromatic compounds and a kind of terpene volatile matter 6 kinds adults of ectropis obliqua is had the volatile matter of behavior activity, then utilize the method for residues to filter out a kind of effective formula being formed by 3 kinds of volatile matters, test result by tea place under Yu Cha village, Shaoxing shows, this formula has significant attracting action to adults of ectropis obliqua.Given this, special proposition the present invention, the Supervise prevention and cure taking it as adults of ectropis obliqua provides effective ways.
Summary of the invention
For prior art problem, the object of the invention is to design provides a kind of technical scheme that lures core preparation method that can significantly lure the attractant of adults of ectropis obliqua and contain this attractant.This attractant is taking manually synthetic volatile matter as primary raw material, and attractant effect female to tea geometrid, male imago is obvious, and has the features such as cost is low, efficiency is high, easy to use and pollution-free.
