Description
Technical field
Insect technical field is largely trapped the invention belongs to semiochemical, and in particular to a kind of rice leaf roller adult is drawn
Lure and its application.
Background technology
Rice leaf roller Cnaphalocrocismedinalis (Guen é e) alias is vertical to be rolled up snout moth's larva, scrapes blue or green worm, belongs to Lepidoptera
Lepidoptera, Pyralidae Pyralididae, are one of main rice grubs of China, are distributed widely in East Asia, Southeast Asia
With the area such as Australia.Rice leaf roller newly hatched larvae is typically first climbed into paddy rice lobus cardiacus or neighbouring leaf sheath, old worm bud, 2 ages
Larva is then general to tie small bud in blade tip or leaf side, and 3 ages started the conjugated blade both sides leaf margin that spins, and whole section of blade is rolled up to front is vertical
Into bud.Larva, which is hidden, wherein gnaws epicuticle and mesophyll.Seedling stage is aggrieved, the normal growth of influence；Tillering and jointing stage is aggrieved, tiller
Reduce, plant shortens, breeding time postpones；Especially heading is aggrieved to full heading time sword-like leave after booting, and influence is yielded positive results, mass of 1000 kernel drop
It is low, or even plant is withered, and 4~5 one-tenth of the paddy rice underproduction can be tried when endangering serious.And the chemical prevention means of conventional spraying pesticide are difficult to
Reach preventive and therapeutic effect, increase dispenser dynamics exacerbates its drug-fast generation again, this brings huge potential to Rice Production
Hidden danger and serious economic loss.
The male moth of rice leaf roller can largely be catched and killed by developing effective the synthetic sex pheromone, and the mating probability for reducing female moth is come
Follow-on insect population number is controlled, the preventing and treating to rice leaf roller is realized.Rice leaf roller is the remote insect that migrates, research card
Real, there is obvious geographic difference in its sex pheromone composition and proportion of composing.Reflected both at home and abroad from female moth sex pheromone body of gland
The sex pheromone made is included along 13- vaccenic acid aldehyde (Z13-18:Ald), along 11- vaccenic acid aldehyde (Z11-18:Ald it is), suitable
13- oleyl alcohols (Z13-18:OH), along 11- oleyl alcohols (Z11-18:OH) and along 13- vaccenic acid alcohol acetic esters
(Z13-18:The component such as AC).It is that selectivity is strong to be mended using sex pheromone and kill male its advantage of moth of rice leaf roller, does not injure natural enemy,
And it is environmentally friendly.And need 4 kinds of pheromones to be compounded in the prior art, certain trapping capability attractant can have just been obtained,
And it is costly, it is unfavorable in benefit murders the application of worm.
The content of the invention
In view of this, it is an object of the invention to provide a kind of vertical volume of the stronger rice of with low cost, simple to operate, allure
Leaf snout moth's larva gyplure and its application.

Present invention also offers application of the described rice leaf roller imago attractant in integrated control rice leaf roller.
It is preferred that, comprise the following steps：
1) synergist is attached on carrier, forms the lure for being attached with synergist；
2) sex pheromone is added on sex pheromone carrier, the lure for being attached with sex pheromone is made；
3) by the step 1) obtain being attached with the lure and the step 2 of synergist) obtain be attached with sex pheromone
Lure be fixed on trapper；
4) in the step 3) obtained trapper is placed in field, traped；
Wherein step 1) and step 2) limitation without time sequencing.
It is preferred that, the step 2) in sex attractant be dissolved in advance in solvent before sex pheromone carrier is added to, shape
Into sex pheromone solution；The solvent is n-hexane or dichloromethane；
It is preferred that, the step 2) in per lure load sex pheromone solution quality be 100~1000 μ g.
The invention provides a kind of rice leaf roller imago attractant, the attractant includes sex pheromone；The property letter
Breath element along 13- vaccenic acids aldehyde, along 11- vaccenic acids aldehyde and along 13- oleyl alcohols by constituting；The suitable 13- vaccenic acids
Aldehyde, the mass ratio along 11- vaccenic acids aldehyde and suitable 13- oleyl alcohols are 100：(5~20)：(5~20).What the present invention was provided
Rice leaf roller imago attractant is made up of 3 kinds of sex pheromones, and the attractant ratio that 3 kinds of sex pheromones are constituted is along 11- vaccenic acids
Aldehyde, suitable 13- vaccenic acids aldehyde, suitable 11- oleyl alcohols and suitable 13- oleyl alcohols (Z13-18:OH) attractant of composition draws
Lure better, the attracting ability of rice leaf roller gyplure can be significantly improved, average each trapper trapping amount more than 10,
And trapping amount is 2.6~4.5 times of the derivant of four kinds of sex pheromone compositions.
Further, the rice leaf roller imago attractant that the present invention is provided also includes synergist phenmethylol, makees phenmethylol
As synergist can with property derivant synergistic function, with the attracting ability of high gyplure.Average each trapper trapping amount
More than 14, trapping amount is 8.6 times of blank example, is 2.2 times of property derivant.The derivant that the present invention is provided can be effective
Field rice leaf roller insect density is controlled, mitigates rice leaf roller harm.

The field trap effect of the gyplure lure of table 2 and synergist lure
As seen from Table 2, in the present invention gyplure lure and the combination of synergist lure, the cnaphalocrocis snout moth's larva amount traped
Noticeably greater than alone gyplure lure, alone synergist lure, it was demonstrated that the synergist that the present invention is provided has significant synergistic effect.
Embodiment 11
Matched according to optimal rice leaf roller sex pheromone lure, fixed sex pheromone component ratio, increase or reduction
Major constituent obtains optimal rice leaf roller sex pheromone lure dosage along the dosage of 13- vaccenic acid aldehyde.
Lure makes：Use the μ g/ μ L solution of each sex pheromone 2 prepared.By different disposal in table 3, it is quantitatively adding each
Sex pheromone component solution, treats that solvent hexane volatilization is drying into lure.
Trapper is set：On plate, lure and lure is attached directly to trapper binding device is fixed on bamboo pole with iron wire, bamboo pole is inserted
Enter rice terrace, fixed trapper position is flushed with rice leaf blade tip, be neatly arranged in ridge and rice field center, it is single to include all places
Trapper is managed, each 10 meters of processing trapper interval, each 3 repetitions of processing, trapping changes trapper position after 2 days.
Being averaged for the rice leaf roller sex pheromone lure of the various dose of table 3 lures worm amount
The table of field test results of the rice leaf roller sex pheromone lure handled by the various dose of table 3 is bright, along 13- 18
Carbene aldehyde (Z13-18:Ald), along 11- vaccenic acid aldehyde (Z11-18:Ald), along 13- oleyl alcohols (Z13-18:OH) with
200μg:22μg:Trapping active highest of the lure that 22 μ g dose ratio (processing A2) is mixed in field, 500 μ g:55μg:
55 μ g dose ratio (processing A3) takes second place.The average trapping amount for handling each trappers of A2 is 11, is significantly higher than other dosage
Average trapping amount.There is an optimal attractive activity scope in the dosage of this descriptive information element, low dose is lured with heavy dose
Effect is not so good as 200 μ g:22μg:22 μ g dose ratio effect is good, because dosage has greatly very much isotropic effect, is unfavorable for luring
Catch；Dosage is too small, and activity is too weak, it is impossible to attract field cnaphalocrocis snout moth's larva.
The gyplure formula and gyplure lure and synergist of the present invention is can be seen that from above-mentioned actual field test effect
Lure combination has preferable attractant effect, and the attractant effect than existing formula lure is strong, the attractant that this explanation present invention is provided
Field rice leaf roller insect density can be effectively controlled, mitigates rice leaf roller harm.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
