Abstract
There is provided a method for the synergistic control of insects which comprises applying to the locus of a transgenic crop which produces an insect toxin a synergistically effective amount of a recombinant insect virus containing a vector which is highly virulent to said insect.
Description
By chemical means control insect pest is that a kind of useful protection crops avoid attack of insect and the method for attacking the damage that is caused for a long time always.More recent, introduced the method that specificity is destroyed crop at the control insect of target insect, this method has been avoided and has been used relevant environment and the ecological hazard of conventional pesticides.A kind of use the in these methods can produce the insect specificity toxin, as the genetic modification crop of the Cry toxin of bacillus thuringiensis (Bacillus thuringiensis).Yet the crop of expression bacillus thuringiensis Cry toxin may show defense reaction in various degree to a large amount of lepidoptera pest species.For example, the cotton variety of expressing CryIA (c) is to tobacco budworm, be cigarette aphid noctuid (Heliothis virescens), high resistance is arranged, but the real noctuid of cotton bollworm paddy (Helicoverpa zea) only there are moderate resistance (J.H.Benedict etc., 1996, Journal ofEconomic Entomology, the 89th volume (1), the 230th page).
These class methods of another control insect are applying biological formulation example such as nucleopolyhedrosis virus (NPV) (United States Patent (USP) 4,668,511) or recombinant nuclear polyhedrosis virus (rNPV) (United States Patent (USP) 5,662,897 and United States Patent (USP) 5,858,353).Yet NPV and rNPV be at the virulence/effort levels of various insect species, can be according to the effectiveness of the toxin of the host range of the medicament that carries virus and insertion coded by said gene and different.For example, the real noctuid of insect species paddy is extremely sensitive to NPV and the rNPV of difference called after HzNPV and HzAaIT, but to autographa california (Autographa californica) NPV (AcNPV) or its rNPV, be the only medium susceptibility (Treacy etc. of tool of AcAaIT, 1999, Proceeding Beltwide Cotton Conf., the 1076-1083 page or leaf).Although will contain existing (the All and Treacy of description of combination that the recombinant nuclear polyhedrosis virus that the target insect species is had a carrier of poisoning toxicity is applied to the genetically modified crops strain, 1997, the 1294th page of Proceedings Beltwide Cotton Conf.), but these genetically modified crops and rNPV agent no matter separately still combine all not provide and prevent the required insect control level of crop loss on the commercial size.
Therefore, the purpose of this invention is to provide preventing crop destruction and the useful synergistic insect control method of economic loss that causes thus.
Another object of the present invention provides and strengthens the breaking-up that genetically modified crops defence attack of insect and invasion and attack are caused and the method for destruction.
A feature of the present invention is that the synergistic insect control and the crop protection method that are provided are special at the target insect species, and shows and have enhanced environmental and eco-compatibility, also provides the insect of commercial acceptable level to control and crop protection simultaneously.
From the following description and the appended claims, other purpose of the present invention and feature will be tangible for those skilled in the art.
The invention provides the method for synergistic insect control, comprise the recombinant insect virus that described insect is had supervirulent carrier that contains to genetically modified crops Zoned application cooperative effective quantity.
The present invention also provides the method that strengthens genetically modified crops defence attack of insect and attack the destruction of being caused.
Although the chemical method Pest Control is a kind of effective means of controlling important agricultural insect insect always, has introduced and more had the specific control method of target insect.Comprise that in these insect specificity methods use produces the genetically modified crops of insect toxins such as bacillus thuringiensis (Bt) toxin by hereditary change or uses natural viral such as nucleopolyhedrosis virus (NPV) or reorganization NPV (rNPV).Yet the genetically modified crops that produce the Bt toxin may show more not satisfied defence degree to the target insect.Similarly, the insect viruses of natural and reorganization when using as the independent method of control insect, the common effectiveness that also shows in various degree.
Although the target insect species had to containing being used in combination of the rNPV of moderately toxic carrier and genetically modified crops is existing describes, but, use described rNPV separately or when described rNPV is used with the genetically modified crops of genetically engineered generation insect toxins, do not obtaining gratifying result for commercial insect control.
Find now, give genetically modified crops, the genetically modified crops of preferred genetically engineered generation insect toxins (insecticide), use and contain the recombinant insect virus that the target insect species is had supervirulent carrier, demonstrate significant synergy (that is the insect that, obtained control effect can expect when using the toxicity recombinant insect virus separately or when using genetically modified crops separately insect control effect much higher).This synergy makes it possible to realize by biological means non-chemically the insect control of commercial useful level.And synergistic insect control method of the present invention makes it possible to achieve the effective resistance control that adapts with environment and ecological rational sustainable agriculture practical activity.
According to the inventive method, to the genetically modified crops kind, the genetically modified crops of preferred genetically engineered generation insect toxins, use the recombinant insect virus that the target insect species is had supervirulent carrier that contains of cooperative effective quantity, preferred recombinant nuclear polyhedrosis virus (rNPV) provides the Collaborative Control to insect pest.That is, use combination results that this toxicity recombinant insect virus causes insect composition extremely and kill insect effect (synergy) than what use killing of killing respectively that insect composition institute expectability arrives individually the insect effect is eager to excel to these genetically modified crops.
The recombinant insect virus that is applicable to strong toxicity carrier of containing of the inventive method comprises rNPV such as HzNPV, HzAzIT, EGTdel or their combination.
The genetically modified crops that are applicable to the generation insect toxins of the inventive method comprise corn and cotton strain (BTK system), for example the NuCotn 33B that expresses Bt
TM(a kind of Bollgard that passes through
TMTransformation event comes from Deltapine DP5415
TMThe transgenic cotton flower variety), or the transgenic corns kind is as expressing MON 810
TMThose of transformation event (YieldGard
TM, Monsanto Co.).
In the operation of reality, can be with the form of compositions formulated, for example wettable powder is applied to genetically modified crops with this toxicity recombinant insect virus, especially produces on zone, leaf or the stem of genetically modified crops of insect toxins, on the preferred leaf by hereditary change.Preferred preparation is described on the U.S. Patent Application Serial of submitting on June 9th, 1,998 09/094,279 common co-pending (incorporating this paper into as a reference).
The cooperative effective quantity of toxicity recombinant insect virus can be according to main condition, and for example the density of the insect-resistant degree of genetically modified crops, the selection of time of using, weather condition, mode of administration, insect colony, target crop species, target insect species wait and change.Usually, when with per hectare 1 * 10
10Individual occlusion body (OB/ha) is to 1 * 10
13OB/ha, preferred 5 * 10
10OB/ha to 12 * 10
11When the ratio of OB/ha is used the toxicity recombinant insect virus to genetically modified crops, the insect control that can obtain to work in coordination with.
In order to be beneficial to further understanding of the present invention, provide following examples, be mainly used in and illustrate its more specifically details.Except defined in the claim, should not think thus the present invention is construed as limiting.
In following examples, by Colby method (Colby, S.R., Weeds, 1967 (15), the 20-22 page or leaf) the definite pair of synergy that the approach insecticides make up, promptly, by each kills the result summation of insect composition gained to independent use, the product that deducts these two results then calculates expection (or prediction) result's (percentage of the insect of elimination) of this combination divided by the value after 100.This is described below by arithmetic mode, and wherein two approach combinations add that by component X component Y forms.
If during greater than the expected results that calculates from this formula, promptly there is synergy in the actual observation result.
In the present invention, the insect control percentage (not using external insecticide) that shows with respect to closely-related contrast crop genetically modified crops of the present invention can be expressed as X; The control percentage of recombinant insect virus of the present invention can be expressed as Y when being used to contrast on the crop.Can use the expection control percentage after aforementioned Colby formula calculates virus and genetically modified crops combination.If the observed result (actual control percentage) that is obtained by the combination of using the virus treated genetically modified crops is during greater than the expected results that calculates, then this combination has synergy.
