Description

Technical Field

[0001] The present invention relates to the technical field of agricultural plant protection, and more particularly to an attractant for the cunning moth. Background Art

[0002] The gypsy moth is an important forestry quarantine pest and occurs seriously in northern my country. Currently, it has occurred in Liaoning, Shandong, Henan, Shaanxi, Hebei, Anhui, Shanghai, Tianjin, Beijing and other provinces and cities, causing huge economic losses.

[0003] Currently, the monitoring and green control of the gypsy moth in the United States primarily uses imported products. Similar domestic products are still in the R&D or even more advanced stage of active ingredient synthesis. Before the development of this invention, no mature and effective domestic products had been released to the market. The main problem lies in the uncertainty of the effective ingredient ratio and the screening of sustained-release materials.

[0004] In summary, how to provide a green control product for the gypsy moth is an urgent problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] In light of this, the present invention provides a gypsy moth attractant. By studying the effective ingredient ratios and slow-release materials of gypsy moth attractants and combining them with field trapping trials, the present invention screened out effective ingredient ratios and suitable carrier materials that meet domestic standards for gypsy moth attractants, thereby producing a product that can replace similar imported gypsy moth attractants.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An American white moth attractant, comprising an active ingredient, an adjuvant and a carrier;

[0008] The active ingredients include the following components in percentage by mass:

[0009]

[0010] Furthermore, an American white moth attractant includes an active ingredient, an adjuvant and a carrier;

[0011] The active ingredients include the following components in percentage by mass:

[0012]

[0013] Furthermore, the content of the active ingredient on a single carrier is 0.1 to 10 mg.

[0014] Furthermore, the auxiliary agent includes a solvent and an antioxidant.

[0015] Furthermore, the solvent is one or more of n-heptane, n-hexane, dichloromethane, and vegetable oil.

[0016] Furthermore, the antioxidant is one or more of BHT, TBHQ, and VE.

[0017] Furthermore, the carrier is a modified plastic tube or composite rubber.

[0018] Furthermore, the raw material of the modified plastic pipe is one or more of modified polyethylene, modified polyvinyl chloride, and modified polypropylene.

[0019] Furthermore, the composite rubber is natural rubber or halogenated butyl rubber.

[0020] Furthermore, an American white moth attractant includes an active ingredient, an adjuvant and a carrier;

[0021] The active ingredients include the following components in percentage by mass:

[0022] cis-9, cis-12-octadecadienal 5%

[0023] cis-9, cis-12, cis-15-octadecatrienal 75%

[0024] cis-3, cis-6-9S, 10R-epoxy-heneicosadiene 10%

[0025] 1, cis-3, cis-6-9S, 10R-epoxy-heneicosatetriene 10%;

[0026] The auxiliary agent includes a solvent and an antioxidant;

[0027] The solvent is vegetable oil;

[0028] The antioxidant is BHT;

[0029] The carrier is a modified polyethylene tube (filled with 2% silica);

[0030] The modified polyethylene tube has a length of 50 mm, a wall thickness of 0.7 mm, and an inner diameter of 0.6 to 0.7 mm;

[0031] The content of the active ingredient is 8 mg per root.

[0032] A method for preparing a gypsy moth attractant comprises the following steps:

[0033] (1) preparing the active ingredients including cis-9, cis-12-octadecadienal, cis-9, cis-12, cis-15-octadecatrienal, cis-3, cis-6-9S, 10R-epoxy-heneicosadiene, and 1, cis-3, cis-6-9S, 10R-epoxy-heneicosadiene according to a formula;

[0034] (2) mixing the active ingredient and the adjuvant (the ratio of the active ingredient to the solvent is determined based on the active ingredient content of a single root or a single pellet, and the amount of the antioxidant is 10% of the amount of the active ingredient) to obtain a pheromone solution of the gypsy moth;

[0035] (3) filling the pheromone solution of the gypsy moth into a modified plastic tube and sealing both ends to obtain the gypsy moth slow-release tube attractant;

[0036] The gypsy moth pheromone solution is soaked in the composite rubber, and after the solvent is dried, the gypsy moth rubber plug attractant is obtained.

[0037] Through the above technical solutions, it can be seen that compared with the existing technology, the beneficial effects achieved by the present invention are as follows: (1) The optimal ratio of active ingredients for attracting the gypsy moth is screened. (2) The gypsy moth attractant is effectively released on a variety of carriers. (3) The product of the present invention can effectively solve the problem of domestic dependence on foreign products of this type. (4) The product of the present invention needs to be used in conjunction with a trapping device, does not target non-target pests, is environmentally friendly, and belongs to the green control product category. (5) The attractant is used in conjunction with a trap in the field to achieve monitoring, detection, reporting, and prevention of gypsy moth adults. BRIEF DESCRIPTION OF THE DRAWINGS

[0106] Experiment 1

[0107] The experiment was conducted in Xinle City, Shijiazhuang City, Hebei Province from May 26 to June 28, 2021. Field tests were conducted using the cuneiform moth attractants prepared in Examples 1, 2, 6, 7, 8, and 9 of the present invention.

[0108] Equipped with universal bucket traps, with 3 replicates for each treatment, randomly distributed, the total capture volume was investigated each time, and the trap positions were rotated.

[0109] The results are shown in Table 1. Figure 1 shown.

[0110] Table 1 Number of traps (pieces)

[0111] May 26 June 3 June 10 June 17 June 28 Example 1 7 4 11 1 4 Example 2 5 6 12 1 2 Example 6 1 0 1 0 0 Example 7 0 2 3 1 0 Example 8 1 6 8 1 0 Example 9 1 3 4 0 5

[0112] Judging from the total amount of trapping in Hebei in 2021, the attractant core containing only two simple components has a poor luring effect, the two more complex components have a strong synergistic effect, and the luring effect of the tubular carrier is equivalent to that of the rubber carrier. Considering the duration factor, the tubular carrier will be the object of further research and optimization.

[0113] Experiment 2

[0114] The experiment was conducted at Majuqiao Wetland Park in Tongzhou District, Beijing from April 21 to May 25, 2022. Field tests were conducted using the cuneiform moth attractants prepared in Examples 1 to 5 of the present invention.

[0115] A universal bucket trap was used, and the CK bait core of the control group was the bait core available on the market. Each treatment was repeated 5 times and randomly distributed. The total capture amount was investigated each time, and the position of the trap was rotated.

[0116] The results are shown in Table 2. Figure 2 shown.

[0118]

[0119]

[0120] According to the optimized attractant data in Beijing, the optimized ratio of cis-9,cis-12-octadecadienal, cis-9,cis-12,cis-15-octadecatrienal, cis-3,cis-6-9S,10R-epoxy-heneicosadiene, and 1,cis-3,cis-6-9S,10R-epoxy-heneicosadiene in the tubular carrier is 5:75:10:10, which is the current optimized ratio. The 5% silica-filled polyethylene tube sustained-release carrier is slightly better than the 2% filled carrier. The attractant effect is comparable to that of currently commercially available products. Judging from the current data, there is still room for further optimization.
