Abstract
The invention discloses an Anagrus nilaparvatae attractant based on plant volatiles and an application of the attractant. The attractant comprises raw materials in percentage by weight as follows: 0-0.01% of acetophenone, 0-0.01% of benzyl alcohol, 0.001%-10% of a solubilizer and the balance of water, wherein the weight percentages of acetophenone and benzyl alcohol are not zero at the same time. According to the Anagrus nilaparvatae attractant based on the plant volatiles, rice planthoppers are controlled through natural enemy, namely, Anagrus nilaparvatae, of the rice planthoppers, and the attractant has high attraction to Anagrus nilaparvatae, is non-toxic and harmless and doesn't pollute the environment.
Description
Technical field
The present invention relates to field of pest control, particularly relate to a kind of Anagrus nilaparvatae attractant based on plant scent and application thereof.
Background technology
Rice fulgorid is one of main pests species in paddy field, Insecta Homoptera (Homoptera) Delphacidae (Delphacidae) insect, popular name fire midge worm, frequent species has brown planthopper (Nilaparvatalugens), white-backed planthopper (Sogatellafurcifera) and small brown rice planthopper (Laodelphaxstriatellus).Rice fulgorid, to the harm of paddy rice, except directly thorn inhales juice, makes paddy growth be obstructed, and time serious, rice clump is agglomerating withered, and outside the dead stalk lodging in even full field, it is laid eggs also can stab rice plant, destroys conducting tissue, hinders nutriment to transport and the viral disease that spreads disease.
Traditional chemical control easily makes rice fulgorid develop immunity to drugs, and contaminated environment, the prevention and control rice fulgorid strategy of development of new is imperative.
At present, application rice grub natural enemy carrys out the method for water prevention rice pest, attracts attention.
The Natural Enemies of rice fulgorid is a lot, can effectively suppress rice fulgorid to breed, as parasitic wasp, spider etc.Anagrus nilaparvatae is Hymenoptera, Thysanidae, and it parasitizes in the ovum of rice fulgorid, and be the important parasitic wasp of brown plant-hopper ovum phase, parasitic rate reaches more than 80% sometimes.Anagrus nilaparvatae is the main ovum parasite of rice fulgorid, and application Anagrus nilaparvatae control rice fulgorid, can effectively control rice fulgorid population quantity, and possess the features such as environmental friendliness.
Research shows, some phanerogamss have attractant effect to Anagrus nilaparvatae, and the attractive activity of these plants is mainly by odor compound.These odor compounds be natural enemy find host, complete look for food, mating and the important semiochemicals of the behavior such as to lay eggs.By establishing the Info-Defense network of paddy rice-rice fulgorid-Anagrus nilaparvatae three trophic level, could fundamentally Control pests quantity.
Between plant and insect, except take food with taken food, parasitic and by except parasitism, also there is the Information Network be associated by volatile compound.After paddy rice is subject to brown planthopper attack, its volatile compound can change, and new compound there will be or old compound ratio rises, and these changes often by natural enemy perception, thus can locate host.
Herbivore-induced plant volatiles can be classified as following a few class: (1) terpenoid, monoterpene, sequiterpene and derivative thereof; (2) greenery smell, the aldehydes of 6 carbon, alcohols and ester class thereof; (3) nitrogenous, sulfur-containing compound; (4) aldehyde except greenery smell, alcohol, ester and some furan derivatives.
Therefore, have great application prospect from the Anagrus nilaparvatae attractant of the angle development of new of these smell chemical combination.
Summary of the invention
Rice fulgorid is easily made to develop immunity to drugs for existing traditional chemical control, and contaminated environment, the object of the present invention is to provide a kind of Anagrus nilaparvatae attractant based on plant scent and application thereof, rice fulgorid is prevented and treated by the natural enemy Anagrus nilaparvatae of rice fulgorid, this attractant is strong to Anagrus nilaparvatae epigamic, nontoxic, free from environmental pollution.
For achieving the above object, the invention provides following technical scheme:
Based on an Anagrus nilaparvatae attractant for plant scent, described attractant is made up of the raw material of following percentage by weight:
Acetophenone 0 ~ 0.01%
Phenmethylol 0 ~ 0.01%
Solubilizer 0.001% ~ 10%
Surplus is water;
The percentage by weight of acetophenone, phenmethylol is 0 time different.
Acetophenone and phenmethylol are plant scent compounds, have stronger attractant effect to Anagrus nilaparvatae.The active component acetophenone of Anagrus nilaparvatae attractant of the present invention, phenmethylol low toxicity, environmentally safe, and to Anagrus nilaparvatae, there is stronger epigamic, this attractant is easy to use.
In attractant, the concentration of active component is the key factor affecting its attractant effect, and often kind of insect has the scope of a best concentration for the reaction of Volatile infrochemicals.
Acetophenone or the phenmethylol of one-component all have attractant effect to Anagrus nilaparvatae, and both also can be with the use of.
In Anagrus nilaparvatae attractant of the present invention, when active component is acetophenone, the weight percent concentration of preferred acetophenone is 0.001%; When active component is phenmethylol, the weight percent concentration of preferred phenmethylol is 0.0025%.When active component excessive concentration or too low time, its attractant effect declines all to some extent.
By two kinds of active component acetophenones and phenmethylol used in combination according to a certain ratio, it is more obviously good to the attractant effect of Anagrus nilaparvatae.
As preferably, described attractant is made up of the raw material of following percentage by weight:
Acetophenone 0.0001% ~ 0.005%
Phenmethylol 0.001% ~ 0.005%
Solubilizer 0.001% ~ 10%
Surplus is water.
More preferably, described attractant is made up of the raw material of following percentage by weight:
Acetophenone 0.001% ~ 0.005%
Phenmethylol 0.001% ~ 0.005%
Solubilizer 0.01% ~ 0.1%
Surplus is water.
Because acetophenone and the phenmethylol solvability in water is less, for improving the attractant effect of attractant, suitable solubilizer need be added, to improve acetophenone and the dissolubility of phenmethylol in water when preparing attractant.The attractant effect tool of selection to attractant of solubilizer has a certain impact, and as preferably, described solubilizer is methyl-sulfoxide and/or OP10 emulsifier.
Methyl-sulfoxide can mix with arbitrary proportion with water, has solvability to multiple compounds, is the transparency liquid of no color or smell under normal temperature; OP10 emulsifier is the condensation product of alkyl phenol and oxirane, soluble in water.Two kinds of equal odorlesses of solubilizer, do not disturb the attractant effect of attractant.
As preferably, described attractant is made up of the raw material of following percentage by weight:
A kind of preferred technical scheme is:
Attractant is made up of the raw material of following percentage by weight:
Another kind of preferred technical scheme is:
Described attractant is made up of the raw material of following percentage by weight:
Another kind of preferred technical scheme is:
Described attractant is made up of the raw material of following percentage by weight:
The compound method of Anagrus nilaparvatae attractant of the present invention is: according to formula ratio by each component Homogeneous phase mixing.
Present invention also offers above-mentioned Anagrus nilaparvatae attractant and lure the application in Anagrus nilaparvatae.
As preferably, concrete application method is: be placed in by the attractant of 20 ~ 50mL in the container with micropore, and hung on by container apart from 5 ~ 10cm place above paddy rice, the horizontal range of adjacent container is 3 ~ 5m, the attractant in 15 ~ 30 days replacing containers.。
Anagrus nilaparvatae attractant of the present invention is applied to lures Anagrus nilaparvatae, and Anagrus nilaparvatae is the main ovum parasite of rice fulgorid, and application Anagrus nilaparvatae control rice fulgorid, can control rice fulgorid population quantity effectively.
Compared with prior art, beneficial effect of the present invention is:
The present invention is based on the Anagrus nilaparvatae attractant of plant scent, prevent and treat rice fulgorid by the natural enemy Anagrus nilaparvatae of rice fulgorid, this attractant is strong to the epigamic of Anagrus nilaparvatae, nontoxic, free from environmental pollution.
