Description
Technical field
The present invention relates to agricultural insect management technical field, more particularly to a kind of protaetia brevitarsis aggregation pheromone and
Its application method.
Background technique
Protaetia brevitarsis (Protaetia brevitarsis Lewis), also known as lineae ablicantes copper brevitarsis, white star are spent latent, white
Star chafer, copper gram dung beetle are a kind of pests of coleoptera cetoniidae, are distributed in northern China major part province, in state
It is national to be distributed mainly on Mongolia, Korea, Japan and Russia etc. outside.Protaetia brevitarsis adult feeding habits are miscellaneous, are often clustered in grape etc.
The organs such as the floral leaf of the trees such as the field crops such as fruit, the corn of fruit tree, willow, seriously affect agricultural product and fruit tree yield and
Quality brings extreme loss to agriculture and forestry production.
Have report using chemical pesticide control protaetia brevitarsis at present, but the harm peak period positive value agricultural product of the worm at
The ripe phase easily causes pesticide residue and pollution using pesticide control.Also, since adult has very strong flight performance, In
It is easy escape during application, reduces chemopreventive effects.In addition, orchard worker also uses sugar-vinegar liquid to trap the worm, effect is simultaneously paid no attention to
Think.Therefore, there is an urgent need to establish the green prevention and control technology of protaetia brevitarsis.
In recent years, weight is increasingly subject to using specificity insect pheromone caused by insect as the technology of pest control
Depending on, the technology have many advantages, such as high sensitivity, control efficiency it is good, it is free from environmental pollution, do not kill natural enemy.Currently, sex pheromone and
Aggregation pheromone is wherein to study more two major classes pheromones.Compared with sex pheromone, aggregation pheromone is often to male, female
Both sexes all have trapping effect, and therefore, effect of the aggregation pheromone in terms of Insect infestation monitoring with Pest control is more and more significant.
Summary of the invention
The object of the present invention is to provide a kind of protaetia brevitarsis aggregation pheromone and its application methods, and dosage is few, dialogue

S2, the polyethylene material bottle of 1mL is chosen as attractant slow release carrier；
S3, the step S1 attractant obtained is fitted into the bottle in step S2, the closed envelope of bottle is made by heating method
Mouthful, lure is made；
S4, the step S3 lure obtained is fixed on trapper, trapper be basin type trapper, Doliform trapper or
Funnel type trapper；
S5, a certain amount of aqueous solution is added in trapper to avoid escape, aqueous solution is that mass concentration is 0.1% soap
Water, mass concentration are 0.1% washing powder water or mass concentration is 0.1% silicone oil.
Therefore, the present invention uses a kind of above-mentioned protaetia brevitarsis aggregation pheromone and its application method, and dosage is few, dialogue
Star brevitarsis is female, male imago has significant attractant effect, environment friendly and pollution-free.
Below by embodiment, technical scheme of the present invention will be described in further detail.
Specific embodiment
Embodiments of the present invention are described further below.
A kind of protaetia brevitarsis aggregation pheromone, protaetia brevitarsis aggregation pheromone is by following components according to respective weight hundred
Divide than composition:
Heptanone 1-8%
Nonanone 1-6%
4- methoxy toluene 62-79%
4- methoxyacetophenone 14-25%.
Protaetia brevitarsis aggregation pheromone is used for the comprehensive treatment of protaetia brevitarsis population monitoring and green prevention and control.
A kind of application method of protaetia brevitarsis aggregation pheromone, steps are as follows:
S1, it protaetia brevitarsis aggregation pheromone is placed in difficult volatile organic solvent is prepared by mixing into attractant, difficulty is waved
Hair property organic solvent is one of mineral oil, atoleine, chlorinated paraffin or sunflower oil；
S2, the polyethylene material bottle of 1mL is chosen as attractant slow release carrier；
S3, the step S1 attractant obtained is fitted into the bottle in step S2, the closed envelope of bottle is made by heating method
Mouthful, lure is made；
S4, the step S3 lure obtained is fixed on trapper, trapper be basin type trapper, Doliform trapper or
Funnel type trapper；
S5, be added a certain amount of solution in trapper, solution be mass concentration be 0.1% suds, mass concentration is
0.1% washing powder water or mass concentration are 0.1% silicone oil.
Pass through following ten implementations to preferably embody the technical effect of protaetia brevitarsis aggregation pheromone of the invention
Example (table 1) is illustrated.
It is clear in Hebei province Baoding during on July 12nd, 2017 to August 9 days and on July 6th, 2018 to August 3rd
Continuous 2 years field trials are carried out in garden county, the village Wang Pan vineyard, the town Wen Ren.
Select growing way uniformly, the consistent vineyard in flakes of management is as test block；Ten kinds of differences that total amount is 0.3g are matched
The aggregation pheromone of ratio and the atoleine of 0.3mL are sufficiently mixed, and are added in polyethylene material plastic bottle and are made not together
Same lure.Also, not place the blank plastic bottle of drug, sugar-vinegar liquid as control.
Trapper selects 30 centimetres of diameter, deep 8 centimetres of plastics basin, in piece diametrically opposite thin iron of basin mouth hoop
Thread, the lure prepared is tied on iron wire, lure is located at basin center and apart from 2 centimetres of the water surface.
Every kind of lure is handled as one, and 3 repetitions, trapper random alignment and spacing is arranged not less than 15 in each processing
Rice.It was investigated every 7 days and records the protaetia brevitarsis adult quantity traped, and recorded respectively by male and female, be shown in Table 1.
1 protaetia brevitarsis aggregation pheromone field trapping effect of table
Note: A: heptanone；B: nonanone；C:4- methoxy toluene；D:4- methoxyacetophenone.Data are average value ± mark in table
Standard is accidentally；Indicate significant (Duncan's Multiple range test) in 0.05 level difference with letters different after column data, same letter indicates
Trapping quantity is not significantly different.
As shown in Table 1, all Example formulations lure what worm amount was much higher than blank control and sugar-vinegar liquid lure worm amount, own
Formula can lure female, male worm simultaneously, and two sex ratios are close to 1:1, illustrate that this attractant is female to protaetia brevitarsis, male worm
There is attractant effect.Wherein, four kinds of heptanone, nonanone, 4- methoxy toluene, 4- methoxyacetophenone component ratios are 3:2:75:
20 formula is best to the trap effect of protaetia brevitarsis, and total trapping amount is more than 400.
Using protaetia brevitarsis aggregation pheromone provided by the invention can carry out field protaetia brevitarsis prediction, forecast with
Trapping, is of great significance for comprehensive treatment protaetia brevitarsis.Also, protaetia brevitarsis attractant is simple for production, and dosage is few,
Easy to use, trapping ability is strong；Meanwhile the protaetia brevitarsis attractant is not directly contacted with farm-forestry crop, is not easy by physical form
Resistance is generated, it is nontoxic to people and animals, it is environmental-friendly；Female, male imago can be trapped and killed simultaneously, and control efficiency is good；In addition, attractant performance is steady
Fixed, the lasting period was long, up to 40 days or more.
Therefore, the present invention uses a kind of above-mentioned protaetia brevitarsis aggregation pheromone and its application method, and dosage is few, dialogue
Star brevitarsis is female, male imago has significant attractant effect, environment friendly and pollution-free.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than is limited,
Although the present invention is described in detail with reference to preferred embodiments, those skilled in the art should understand that: its according to
So can be with modification or equivalent replacement of the technical solution of the present invention are made, and these modifications or equivalent replacement cannot also make to repair
Technical solution after changing is detached from the spirit and scope of technical solution of the present invention.
