Abstract
The invention relates to the filed of insect trapping and in particular relates to apolygus lucorum sex pheromone. The apolygus lucorum sex pheromone comprises trans-2-butyl vinyl ester, butyl butyrate and levodopa, wherein the volume or weight ratio of trans-2-butyl vinyl ester to butyl butyrate to levodopa is 1:1:2, 1:2:1, 2:1:1 or 3:3:2. Through screening of a lot of experiments, ingredients and ratio of the apolygus lucorum sex pheromone are developed. The apolygus lucorum sex pheromone artificial feed formula comprises only three active ingredients, and the apolygus lucorum sex pheromone has a good trapping effect after being screened and matched.
Description
Technical field
The present invention relates to insect attraction field, specifically, relate to green plant bug sex pheromone.
Background technology
Green plant bug is a kind of important pests of Cotton in China of causing harm, and all has distribution in the Yangtze river basin and the Huanghe valley.The harm time of green plant bug to cotton is long, is continued until the term of opening bolls from seedling, and the phase of causing harm reaches more than 4 months.Green plant bug sucking mouth parts lunges the tender head of cotton, growing point, young flower bud, young bell, draws juice.Cotyledon period growth bud point is killed, turns black, dries up, not regrowth; After true leaf occurs, terminal bud is injured withered, and twig grows thickly, and becomes " bull is cotton "; Be pore shape when tender leaf is killed, after mounted blade, large area is broken, is commonly called as " broken leaf is crazy "; The main heart and the limit heart killed, form branches and leaves " the broom seedling " of growing thickly; Bud be injured after bract open, first present yellowish-brown, then witheredly to come off; After cotton buds and bolls are killed, there is water stain spot in light wound, and heavy cotton boll ossifys and comes off.
Soil of transgenic Bt cotton is after China's establishing in large scale, the lepidoptera pests such as cotton bollworm are controlled effectively, but due to the significantly minimizing of cotton field chemical insecticide consumption and frequency of usage, the sucking pest population quantity such as green plant bug increase, occurrence injury is in increasing the weight of trend year by year, and general cotton field attacked trees rate reaches 30% ~ 40%, and serious reaches 60% ~ 90%, to be injured the general underproduction 10% ~ 20% in cotton field, to be up to more than 60%.Green plant bug has become the Severe pests of Cotton in China, produces threaten greatly Cotton in China.Except causing harm except cotton, green plant bug is also caused harm the crops such as jujube, peach, apple, cherry, grape, tea tree, has become the significant problem affecting China's various crop production safety.
The control of current green plant bug mainly relies on chemical pesticide, and the extensive application of insecticide must cause the pollution of the drug-fast rising of green plant bug and environment, the effective controlling way therefore sought outside chemical control to be the task of top priority.Need the many-sides such as the biology to green plant bug, ecology, physiology, toxicology to study, sex pheromone is the biology carrying out two sexual lifves, for identifying mutually and the material that discharges, can be made female, male close, and cause mating by this kind of material.Generally mostly be the passive sporadic pheromones of female secretion, lure and draw male generation excitement initiatively, but also have by the kind of male secretion.Therefore, research pheromones can effectively lure collection cotton leaf bug to find target towards sex pheromone, unifiedly in sex pheromone set-point can carry out chemical control, effectively can reduce breeding and the harm of fleahopper, reduce harm radix of future generation, simultaneously for crops prediction carries out theoretical foundation, the control for cotton leaf bug provides good basis.
Therefore, development effectively lures the sex pheromone formula of collection cotton leaf bug adult, for the ecology of cotton leaf bug and biological control provide good basis.
Summary of the invention
Main purpose of the present invention is to provide a kind of green plant bug sex pheromone.
According to green plant bug sex pheromone of the present invention, it comprises trans-2 fourth vinyl acetate, butyl butyrate, levodopa,
Wherein, to female worm property, the proportioning of three's ratio is: 1.9:2:1,2.1:2:1 and 3:3:2, to the proportioning of male worm is: 2:1:1 and 2:1.7:1(by volume or part by weight) all adopt n-octyl alcohol make solvent.
According to the specific embodiment of the present invention, result of the test shows, be used alone trans-2 fourth vinyl acetate, butyl butyrate, levodopa have certain attraction rate to green plant bug, but during conbined usage three, the attraction rate of female worm or male worm is reduced, at that time using aforementioned proportion preparation three of the present invention as the sex pheromone of green plant bug, display, all significantly increase the attraction rate of female worm and male worm, therefore the sex pheromone formula of green plant bug of the present invention has synergistic function.
After using transgenic cotton against pests establishing in large scale, the status of cotton pest develops, and the insects such as green plant bug rise to primary pest, causes harm and increases the weight of year by year.Cotton leaf bug has stronger flight performance and activity, brings great difficulty to chemical control, and for the problems referred to above, the present invention, through a large amount of experiment screenings, have developed composition and the proportioning of the sex pheromone of above-mentioned green plant bug.The active ingredient of this artificial feed formula only has 3 kinds, but it is after screening proportioning, and its gathering effect is good.
Embodiment
The each raw material used in following embodiment, except particularly pointing out, all can by commercially available acquisition.
Embodiment one:
1, the screening of indoor composition and proportioning:
Adopt n-octyl alcohol to make solvent, screen according to different proportionings, cumulative volume is 1ml.
Table 1 different formulations pheromones is to effective attraction rate (%) of green plant bug
From table 1, when being used alone trans-2 fourth vinyl acetate, butyl butyrate, levodopa, to the attraction rate 10% ~ 60% of female worm or male worm; And when the trans-2 fourth vinyl acetate of conbined usage, butyl butyrate, levodopa, be 0% ~ 70% to the attraction rate of female worm or male worm, fluctuate very large, three's proportioning improper causing significantly reduces to the attraction rate of female worm or male worm as can be seen here, to female worm property lure effect proportioning be: 1.9:2:1,2.1:2:1 and 3:3:2, be: during 2:1:1 and 2:1.7:1 that attraction rate is Synergistic trend to male worm proportioning.
Embodiment two:
Genetically modified plants Environmental security supervision and inspection center of the Ministry of Agriculture (Anyang), prepared by 2013 pairs of embodiments 1, green plant bug sex pheromone composition and proportioning have carried out gathering effect experiment in field at green plant bug occurrence in peak period, result shows, this composition and proportioning have good attractive effect to green plant bug, thus have played good preventive and therapeutic effect in cotton field.
Table 2 field different times lures the par (head) of collection green plant bug
| Proportioning | June 2 | June 7 | June 12 | June 17 | June 22 | June 27 | July 2 |
| 2:2:1 | 1.10 | 2.70 | 1.40 | 1.30 | 0.00 | 0.00 | 10.10 |
