Description
Technical Field
The invention relates to an attractant for trapping pests, in particular to an attractant for trapping trichoplusia agnata for the omnivorous pests of precious tree species, flower trees, vegetable crops and the like and an application method thereof.
Background
Argyrogramamma agnata Staudinger, also known as black spot Argyromandina agnata and bean geometrid, belongs to Lepidoptera, Noctuidae, is distributed all over the world, and is an important pest of precious tree species such as paulownia, Sophora japonica, bamboo, carnation, purple perilla, beans, eggplant and the like, flowers, woods and vegetable crops. The insect is damaged by larvae, the larvae eat to cause the incised leaves or holes, all the leaves can be eaten in serious occurrence, 4-7 generations occur in the year, and the egg laying amount of the adult insects is up to 700.
The larvae of the silver noctuid have the predatory property, most of the commonly adopted control methods at present use black light lamps to trap and kill adults, protect and utilize natural enemies, chemical agents to control and the like, but the methods are time-consuming and labor-consuming, have not necessarily obvious effects, and can cause pollution to the environment, cause medicament residues, cause pesticide resistance of pests, kill natural enemies, pollute food and other problems.
At present, the Heliothis virescens attractant and the application thereof are also researched, but the Heliothis virescens attractant has more used components, high substance synthesis difficulty and high cost.
Disclosure of Invention
The invention aims to solve the technical problem of providing the attractant for the Trichoplusia ni and the application method thereof, wherein the attractant is convenient to apply, simple in components, low in cost, strong in specificity, free of pollution and free of harm to natural enemies.
The invention solves the technical problems by the following technical scheme:
the main effective component adopted by the attractant for the silver looper is cis-7-dodecenyl acetate (Z7-12: AC), and the purity of the cis-7-dodecenyl acetate reaches more than 98 percent; when in preparation, 400 mu g of cis-7-dodecenol acetate is dissolved in 10 mu l of organic solvent, and the adopted organic solvent is n-hexane with the purity of more than 98 percent for high performance liquid chromatography.
The application method of the attractant for the Trichoplusia agnata comprises the following operation steps:
1) manufacturing a lure: dissolving cis-7-dodecenyl alcohol acetate in an organic solvent, and then putting the solution into an organic silica gel lure core, wherein the amount of the cis-7-dodecenyl alcohol acetate contained in a single lure core is 400-800 mu g;
2) and (3) putting the organic silica gel luring core into the trapper to monitor the occurrence dynamics of the field Heliothis virescens, predict the occurrence degree of the Heliothis virescens, guide the timely implementation of control measures and simultaneously trap and kill the Heliothis virescens.
The silver pattern noctuid attractant has the following beneficial effects:
1. the cis-7-dodecenyl alcohol acetate is used as the main component of the attractant, so that the emergence period of the adult insects can be monitored, a large number of adult insects can be killed, the population density is reduced, and the harm of the adult insects is reduced.
2. The attractant can be used for directly preventing and controlling the cabbage loopers, can reduce the use of chemical pesticides, improves the food safety, protects the environment and natural enemies, improves the efficiency and the effect of preventing and controlling the cabbage loopers, and has remarkable social and ecological benefits.
3. The attractant disclosed by the invention is convenient to apply, simple in components, low in cost, strong in specificity, free of pollution and harmless to natural enemies.
Drawings
FIG. 1 is a graph showing the effect of the attraction of the silicone gel used in example 3 of the present invention in an amount of 0 to 800. mu.g/piece of cis-7-dodecenyl acetate.
Detailed Description
The Heliothis virescens attractant of the present invention is further described below with reference to specific examples.
Example 1, testing was performed with four common moth attractants:
three known moth monomer attractants with the concentration of more than 98 percent are selected in the test. The attractant is added into the organic silica gel lure according to the dosage of 400 mug/piece, the three components are mixed into the attractant D according to the proportion of 1:1:3, and the four moth attractants and the proportion thereof are shown in the table 1.
TABLE 1 four moth attractants and their proportions
This example includes the monomer amounts of the three moth attractants and the amount of a mixture.
Example 2, the four moth attractants of example 1 were tested for trapping heliothis virescens:
in the emergence period of the Trichoplusia ni, a triangular trap is used for hanging a lure containing 400 mug of attractant in the field, the lure keeps a distance of 1 cm from the bottom surface of the trap, the number of the lured imagoes is counted, and the effect is shown in Table 2.
TABLE 2 field attracting Heliothis virescens effect of four moth attractants
This example illustrates that A, C monomer has no attractant effect on Trichoplusia ni, whereas B, D substance has an attractant effect on Trichoplusia ni.
Example 3, an attractant was prepared in the method of the invention:
1) manufacturing a lure: dissolving cis-7-dodecenyl acetate in an organic solvent, putting the solution into an organic silica gel lure core, and testing the organic silica gel lure core by using three groups of 0 mu g, 400 mu g and 800 mu g of cis-7-dodecenyl acetate;
2) the organic silica gel trapping cores are placed into traps and then placed into the field, the total number of the trapped imagoes is counted, the average trapping quantity of each trap is calculated, and the effect is shown in figure 1.
As described above, the moth attractant is applied to the field, the attractant for attracting the Trichoplusia ni is invented, has simple components and low components, is easy to operate, and can be used for monitoring and controlling the Trichoplusia ni.
