Problems solved by technology

[0003] The larvae of silver print moth are gluttonous. At present, the control methods usually used are mostly trapping and killing adults with black light lamps, protecting and using natural enemies, and controlling with chemical agents. It will pollute the environment, cause chemical residues, cause pest resistance, kill natural enemies, contaminate food and many other problems
[0004] At present, there are also researches on the attractant of silver-leaved armyworm and its application, but there are many ingredients used, and the synthesis of substances is difficult and costly

Embodiment 1

[0017] Example 1, testing with four common moth attractants:

[0018] In this experiment, three known moth monomer attractants were selected, and the concentrations were all above 98%. Add the attractant to the silicone lure core at a dose of 400 μg / piece, and then mix these three components at a ratio of 1:1:3 to form attractant D. The four moth attractants and their ratios are shown in Table 1 shown.

[0019] Table 1 Four kinds of moth attractants and their proportions

[0020]

[0021] This example includes individual amounts of three moth attractants and an amount of a mixture.

Embodiment 2

[0022] Embodiment 2, four kinds of moth attractants in example 1 are used to entrap silver-leaved spider moth test:

[0023] During the occurrence period of silver leaf moth, a triangular trap was used to hang a lure core containing 400 μg of attractant in the field. The distance between the lure core and the bottom surface of the trap was kept 1 cm, and the number of adults trapped was counted. The effect is shown in Table 2.

[0024] Table 2 The effect of four kinds of moth attractants on attracting silver-leafed moths in field

[0025]

[0026] This embodiment illustrates that A and C monomers have no attractant effect on silver-leaved armyworm, while B and D substances have attractant effect on silver-leaved armyworm.

Embodiment 3

[0027] Embodiment 3, prepare attractant with the method of the present invention:

[0028] 1) Making lures: dissolve cis-7-dodecenyl acetate in an organic solvent and put them into organic silica gel lures, and make the silicone lures contain cis-7-dodecenyl acetate as Three groups of 0μg, 400μg, and 800μg were tested;

[0029] 2) Put the silicone lure core into the trap, and then put it into the field, count the total number of trapped adults, and calculate the average amount of insects attracted by each trap, see the effect figure 1 shown.

[0030] As mentioned above, the present invention has invented an attractant for attracting silver-leafed moths by applying the moth attractant in the field.

Abstract

The invention discloses an argyrogramma agnata attractant and an application method thereof. The main effective component of the attractant is cis-7-dodecenol acetate of which the purity is more than 98%. During preparation, 400-800mu g of cis-7-dodecenol acetate is dissolved in 10mu l of an organic solvent, and the adopted organic solvent is normal hexane which has the purity of more than 98% and is used for high performance liquid chromatography. During application, a lure is put in a trap device, the occurrence dynamic of the argyrogramma agnata in the field can be monitored, the occurrence degree can be forecasted, prevention and treatment measures can be guided to be implemented in real time, and the argyrogramma agnata can be trapped and killed, so that the argyrogramma agnata attractant has obvious ecological and social benefits.

Description

technical field [0001] The invention relates to an attractant for trapping pests, in particular to an attractant for trapping omnivorous pests such as precious tree species, flowers, trees and vegetable crops, and an application method thereof. Background technique [0002] Argyrogramma agnata Staudinger, also known as silver-spotted silver-spotted moth and bean geometrid, belongs to Lepidoptera, Noctuidae, and is distributed all over the world. , eggplant and other precious tree species, flower trees and important pests of vegetable crops. The larvae are harmful. The larvae feed on the leaves and lead to nicks or holes. In severe cases, the entire leaves can be eaten up. There are 4-7 generations per year, and the adult eggs can reach up to 700 eggs. [0003] The larvae of silver print moth are gluttonous. At present, the control methods usually used are mostly trapping and killing adults with black light lamps, protecting and using natural enemies, and controlling with ch...
