Abstract

The present invention relates to an insect killing method by distributing a moth pest sexual attraction agent in fields, and comprises traps (1) with the sexual attraction agent inside. The present invention is characterized in that the traps (1) are distributed in a field by a distribution method with more around and less in the center; in the distribution method, one trap (1) is arranged in the position with 40 to 50 meters of the length and 10 to 20 meters of the width in each row in the position of 2 to 4 rows of the periphery (2) of the field trapping area, and one trap (1) is arranged in the position with 30 to 50 meters of both the length and the width in every row in the position of the field center section (3) within 2 to 4 rows. Compared with the prior art, the present invention has the advantages that the traps are arranged according to the characteristics of moth movement; the insect killing action of the traps is fully exerted; consequently, insect killing efficiency is effectively increased; 289 * 667 m <2> of area is taken as the example, 578 traps need arranging according to the prior art, and the number of the traps can be reduced to 193 by adopting the distribution method with more around and less in the center; the reduced ratio can be increased continuously with the enlargement of the continuous utilization area; for example, the continuous area is 625 * 667 <2>, the number of the traps can be reduced from 1250 to 345, and then, the application cost of insect killing is greatly saved.

Description

A kind of killing method that utilizes moth class pest gyplure to arrange in the field

Technical field

The present invention relates to a kind of killing method that utilizes moth class pest gyplure to arrange in the field.

Background technology

It is that a kind of noctuid female insect sex pheromone of synthetic that utilizes lures the novel nocturnal moth class insect of collection male imago to kill technology that the noctuid gyplure lures the collection insect, promoting this kind environment-friendly pesticide technology at present in ground vegetable growings summer and autumn such as Shanghai, Hangzhou, Fujian, Ningbo, Wenzhou, target pest is prodenia litura, beet armyworm and diamond-back moth etc.Existing using method is: every 667m ²(1 mu of ground) lays 2～5 trappers, adopts the method for evenly arranging in the field.Tabulation as follows:

Producing No. 2 prodenia lituras with Taiwan lures the core different amounts to lure the worm amount

In the middle of luring, consumption periphery 3 rows lure worm on average to lure the worm amount to lure worm number/mu

Worm number/trapper number/trapper worm number/trapper

1 mu 1 200.43 56.61 105.57 153.0

2 mu 1 388.935 129.645 187.265 144.1

3 mu 1 582.41 255.59 255.59 139.7

5 mu 1 758.4 423.44 505.6 126.4

7 mu 1 884.5 565.5 565.5 103.6

10 mu 1 1229.56 854.44 854.44 104.2

From above-mentioned tabulation numeral as can be known, trapper moth amount at the field periphery is significantly higher than medium position, promptly there is tangible marginal effect, so adopt the method for evenly arranging in the field, there is obvious un-reasonable phenomenon in its design, and will waste needn't economic loss, improve the trapping cost, described its method of arranging is further improved.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of insecticide efficiency height at above-mentioned prior art present situation, catch and kill the low and killing method that utilizes moth class pest gyplure to arrange in the field that design in the high characteristic of limit, field motion frequency at moth class adult of cost.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: the killing method that this utilizes moth class pest gyplure to arrange in the field, include the trapper that is built-in with gyplure, it is characterized in that the method for arranging that described trapper adopts the limit to dredge in close is distributed in the field, its method of arranging is: in two to four rankings of field trapping area periphery are put, every row is that a trapper is placed in 10 to 20 meters positions with long 40 to 50 meters wide, and arrange with interior field medium position described two to four, every row is 30 to 50 meters positions with length and width and places a trapper.

As improvement, it is three rows that described field trapping area periphery can be preferably, and every row places a trapper with long 45 meters wide 15 positions.

As further improvement, the medium position in described field may be selected to be with length and width and is trapper of 45 meters positions placements.

Improve, the receptacle that described trapper can include grabber and be attached thereto, described grabber comprise outer cover and be fixed on and lure the core dead lever in the outer cover again, describedly lures on the core dead lever being provided with several and being used for luring core to intert wherein and fixing aperture at interval.

Compared with prior art, the present invention adopts trapper to be distributed in the field with the method for arranging that Bian Mizhong dredges, in 2 to 4 rankings of field trapping area periphery are put, with long 40 to 50 meters wide is that 1 trapper is placed in 10 to 20 meters positions, and arrange with interior field medium position described 2 to 4, being 30 to 50 meters with length and width is that 1 trapper is placed in the position.The invention has the advantages that trapper arranges by the characteristic of moth class activity, brought into play the insecticidal action of trapper fully, thereby improved the insecticide efficiency of trapper effectively; With 289 * 667m ²(17 * 17 mu) area is an example, according to former technology 578 trappers need be set, and adopts " Bian Mizhong dredges " method of arranging can reduce to 193, the quantity that is trapper has reduced 66.61%, along with usable floor area in flakes increases, the ratio of minimizing can constantly increase, and is 625 * 667m as area in flakes ²(25 * 25 mu), the quantity of trapper can reduce to 345 from 1250, and slip will reach 72.40%, thereby save the application cost of catching and killing insect significantly, so the present invention is a kind of technology very with practical value, be worthy of popularization.
