Description
Technical field
The present invention relates to a kind of insect sex attractant and lure core, relate in particular to a kind of core that lures that is used to prevent and treat 2 committee noctuids.
Background technology
2 committee noctuids (Proxenus lepigone (Moschler)), different name Athetis lepigone belongs to Lepidoptera, Noctuidae.Harm in recent years enlarges gradually, and since in late June, 2011,2 committee's noctuids harm summer corns are seen on ground such as Hebei, Shandong, Henan, Anhui in succession, and some areas take place serious, and seedling death phenomenon appears in indivedual plot, and peasant's income is caused heavy losses.This insect larva is mainly bored moth maize seedling root stem or cuts off shallow top layer root, causes corn lodging or dead, causes the disconnected ridge that is short of seedling, and can cause and ruin kind; The host is except that corn in harm, also endangers soybean, peanut, also gets wheat seed and volunteer that food wheat straw and wheat bran are sprouted down.Larva endangers summer corn in late June to early July, and is general along ridge harm, and the strain of commentaries on classics harm habit is arranged; Gregariousness is arranged, and the bull larva often accumulates in harm under the strain, can reach the 8-10 head; Like daytime hiding and endangering maize seedling under the broken wheat straw around the corn seedling or in the seam of the soil about 2cm; The corn field that straw is thicker takes place heavier.The strong phototaxis of adult tool.
In control, 2 committee noctuids are for boring moth harm type insect, and thicker crust makes medicament be difficult to permeate more to have increased the difficulty of control, and especially chemical control very easily causes operating personnel to poison, so suddenly wait to develop a kind of biopesticide safely and effectively.
Summary of the invention
For solving the problems of the technologies described above, the present invention provides a kind of environmental protection safe in utilization, easy to operate, control efficiency obviously, can monitor the core that lures that is used to prevent and treat 2 committee noctuids of insect pest situation.
The core that lures that is used to prevent and treat 2 committee noctuids of the present invention comprises slow-released carrier, in the said slow-released carrier sex attractant is set, and slow-released carrier is cuff formula rubber stopper or plastic tube; Said sex attractant is processed by the raw material of following weight: along 7-12 carbon acetic acid esters 0.1-1.0mg, and along 9-14 carbon acetic acid esters 0.1-1.0mg, antioxidant 0.1mg.
The core that lures that is used to prevent and treat 2 committee noctuids of the present invention, when said slow-released carrier was plastic tube, the internal diameter of plastic tube was 0.1-3mm.
The core that lures that is used to prevent and treat 2 committee noctuids of the present invention, said slow-released carrier is processed by composite rubber material, polyvinyl chloride, polyethylene or polypropylene plastics material.
The core that lures that is used to prevent and treat 2 committee noctuids of the present invention, said antioxidant is a 2,6 di tert butyl 4 methyl phenol.
The present invention puts into supporting trapper with the above-mentioned core that lures that contains sex attractant; Place the control district to this trapping device then, can catch 2 committee noctuid adults in field, adult reduces then mating rate reduction; Can effectively reduce simultaneously the quantity of larva of future generation, reach the purpose of control.
Beneficial effect compared with prior art of the present invention is:
1) in 2 committee noctuids control districts, 2 committee noctuids is set lures generation and the growth and decline of 2 committees in the grasp field noctuid that core and supporting trapper can be promptly and accurately dynamic; Can effectively reduce the harm of 2 committee noctuids through mass trapping, have advantages such as single-minded, the ecology recovering of control;
2) the present invention avoids the use of chemical pesticide, helps protecting environment, and social benefit and ecological benefits are obvious;
3) the present invention is simple to operate, and the term of validity is long, is easy to promote.

Experiment
Experimental session is on July 31st, 1 2011 on May 10th, 2011, test block area 5 * 666.7m
2, summer corn plant growing way is even; The trapper that six 2 committee noctuids lure core and a supporting trapper and a blank is set, and described trapper is the basin trapper.Lure core apart from water surface 1-2 centimetre, add a little washing powder in the water.It is a processing that 2 every kind committee noctuids lure core and supporting trapper, establishes 3 repetitions.Each trapper is 1.0m overhead, and each trapper is arranged in a linear, spacing 30m, 2 committee's noctuid male worm quantity in each trapper of 8:00-9:00 inspection in every day in the morning, and record respectively.The said core that lures can use 1-2 month.The said core that lures can not be reused.
The experimental result table is following:
The field lures the moth experiment to show, sex attractant of the present invention lures core that 2 male moths of committee noctuid are had strong attracting action, and the variation of induced moth number can reflect in time, exactly that the growth and decline of 2 committees in field noctuid are dynamic.
The present invention can take to disturb the mode of mating to organize and implement: promptly in the test block, generally discharge of the present invention two and select the gyplure of committee noctuid; Can disturb the normal mating of 2 committee noctuids effectively; It can not effectively be raised up seed, thereby reduce harm crop.The present invention can also with two select the committee noctuid gyplure and chemosterilant, virus or bacterium be used.Promptly male worm is lured, it is contacted with chemosterilant, virus or bacterium, fly away then, contact with other insect, mating, like this, cause 2 noctuid populations of entrusting to suffer damage its better effects if with gyplure.
In sum, provided by the inventionly a kind ofly be used to prevent and treat two and select the gyplure of committee noctuid, be used for the insect pest situation monitoring no matter be; Still through trapper or the direct pest control of interference mating method, all help protecting natural enemy, improve the effect of 2 committees of control noctuids; Simultaneously; Can also avoid the use of the pollution that chemical pesticide causes, the protection environment has remarkable social benefit and ecological benefits.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
