Embodiment 1

[0026] Example 1 The structure of tea caterpillar sex lure

[0027] Referring to Fig. 1, the sex lure device is made up of the lure core 2 that is loaded with sex lure and the color plate 1 that is coated with glue. The lure is made of rubber, similar to a small bottle cap, and the one without pheromone is called a rubber head. The basic component of the sex attractant is 10,14-dimethylpentadecyl isobutyrate, and synergists are respectively added and mixed to form the sex attractant of the present invention. The color palette includes bud green, frangipani yellow and white 3 colors.

Embodiment 2

[0028] Embodiment 2 traps the method for tea caterpillar male adult

[0029] (1) 10,14-dimethylpentadecyl isobutyrate (10,14-dimethylpentadecyl isobutyrate), the main component of tea caterpillar sex pheromone, is used as the basic component, and the purity is chromatographically pure;

[0030] (2) Select 4 types of synergist components from the volatile compounds of tea shoots respectively, the purity is chromatographically pure, and form 4 types of sex attractants with 10,14-dimethylpentadecyl isobutyrate, 4 The components of class synergists are:

[0031] Type A: Acetate-Z-3-hexenyl ester;

[0032] Class B: Z-3-hexenyl acetate, E-2-hexenal, Z-3-hexen-1-ol;

[0033] Type C: Acetate-Z-3-hexenyl ester, linalool;

[0034] Class D: Linalool.

[0035] The content of each component of 10,14-dimethylpentadecyl isobutyrate and synergist in each type of sex attractant is 0.1-2.00 mg.

[0036] (3) Soak the rubber head made of natural rubber with absolute ethanol for more than 24 ...

Embodiment 3

[0044] Example 3 Screening of the sex attractant with the strongest lure effect

[0045] In the tea areas of northern Zhejiang, Anhui and Chongqing, there are two generations of tea caterpillars per year, and the peak eclosion period of the first generation adults is from mid-June to mid-July. From June 18th to July 4th, 2004, trapping was carried out in an organic tea garden in the mountainous area of ​​Shexian County, Anhui Province. The six sex attractants A-F were loaded on the lure cores for experiments, each repeated 10 times, and the sex attractants The configuration is as follows:

[0046] A: 1 mg 10,14-dimethylpentadecyl isobutyrate + 1 mg acetate-Z-3-hexenyl

[0047] B: 1mg 10,14-dimethylpentadecyl isobutyrate+1mg-Z-3-hexenyl acetate+1mg E-2-hexenal+1mg Z-3-hexen-1-ol

[0048] C: 1mg 10,14-dimethylpentadecyl isobutyrate + 1mg -Z-3-hexenyl acetate + 1mg linalool

[0049] D: 1mg 10,14-dimethylpentadecyl isobutyrate + 1mg linalool

[0050] E: 1mg 10,14-dimethylpenta...

Abstract

The invention provides an entrapping method for male imagoes of euproctis pseudoconspersa, which selects the euproctis pseudoconspersa sex pheromone 10, 14- dimethyl 15 carbon isobutyric acid ester as the basic component and prepares a euproctis pseudoconspersa gyplure by mixing with the volatile compound. The content of each component is 0.01 to 2.00mg in the gyplure, and by combining the gyplure with a viscose color plate the euproctis pseudoconspersa sex pheromone can be produced for entrapping male moths during the prime time of moth appearance. The trap takes the shape of a plate; the lower hemline is aligned with the tea shoot; the inter-trap distance is 10 to 15 meters. The invention unites for the first time the insect pheromone with the color for entrapping male imagoes of caterpillars, thus the entrapping rate is high and the copulation probability is reduced, preventing the massive eggs from being fertilized, thus the initial population number of the next generation can be depressed. The invention has the advantages of convenient use, low cost, deduction and exemption of pesticide application, non-pollution, and facility for the production of organic tea and pollution tea.

Description

technical field [0001] The invention belongs to a method for trapping tea caterpillars, and relates to a method for trapping male adults of tea caterpillars, and mainly relates to a method for trapping male adults of tea caterpillars in combination with a sex attractant and a viscose color plate. Background technique [0002] The tea caterpillar Euproctis pseudoconspersa Strand belongs to the family Lepidoptera and is a frequent pest in the tea area of ​​my country. Adults and larvae are densely covered with poisonous hairs, and the egg masses are produced in the middle and lower layers of the tea bushes, and are also covered with poisonous hairs. The poisonous hairs touch the skin and cause redness, swelling, itching, and affect field operations. The larvae chew on the buds and adult leaves of tea trees, and when they are serious, they eat the bark. When they are mature, they pupate in the soil layer 1-2 inches deep in the fallen leaves of the rhizosphere. For a long time,...
