Problems solved by technology

[0003] At present, the method of preventing and controlling the green leafhopper is mainly chemical control. Due to the serious overlapping of generations of the green leafhopper, most tea areas adopt chemical control more than 10 times a year, resulting in a significant increase in the resistance of the green leafhopper. The abuse of chemical pesticides has obvious lethality to other arthropods (such as neutral insects, natural enemies, etc.) in the tea garden community, destroying the balance of biodiversity in the tea garden, leading to the rampant increase of some secondary pests

Embodiment 1

[0027] The first step is the test of mint plant volatiles to lure the small green leafhopper with false eyes

[0028] 1. Flavor source

[0029] Mentha haplocalyx Briq. is a weed that grows naturally in the tea garden of China Jiliang University. During the experiment, the young part was cut as the flavor source material, and the volatiles were released to attract the green leafhopper with false eyes. There are 6 doses of 0.5g, 1g, 3g, 5g, 7g and 9g, and each dose is tested 5 times. The control was clean air.

[0030] 2. Insects to be tested

[0031] The female and male adults of Leafhopper with false eyes were collected from the tea garden of China Metrology Institute, and were reared on potted tea trees in insect cages, allowing them to mate and lay eggs freely. After the eggs hatched into nymphs, the nymphs emerged into adults. Before the start of the test, the adult worms were taken out with a finger tube, starved for 1 hour, and then the behavioral test was performed. ...

Embodiment 2

[0073] Time rhythm of leafhoppers flying to lures in the tea garden in Example 2

[0074] 1. Materials and methods

[0075] Select the six-component lure core, the four-component lure core, the 10-component lure core in the 4th step of embodiment 1 for use -2 g / ml phyllyl acetate single-component lure, and then 10 -2 g / ml phyllyl acetate and 10 -2 g / ml linalool is dubbed into a two-component lure. The 4 kinds of lures are respectively attached to the white round sticky boards with a diameter of 25 cm. With reference to the 4th step procedure of example 1, test is carried out in the tea garden, and every kind of lure core is repeated 30 times. Divide the survey time of a day into the following 8 time periods: 19:30-05:30, 05:30-07:30, 07:30-09:30, 09:30-11:30, 11:30-13 :30, 13:30-15:30, 15:30-17:30 and 17:30-19:30. The number of leafhoppers on the swatches was surveyed during the last 30 minutes of each session. From October 24th to October 28th, a 5-day time rhythm surv...

Embodiment 3

[0079] Embodiment 3 The effect of six components of mint volatile matter and its mixture adding slow-release agent to attract leafhoppers

[0080] 1. Materials and methods According to the test procedure in the tea garden in the 4th step of Example 1, select the six component information substances in the 4th step: 10 -2 g / ml phyllyl acetate, 10 -4 g / ml 3-octanone, 10 -4 g / ml caryophyllene, 10 -6 g / ml(R)-(-)-α-phellandrene, 10 - 8 g / ml cineole and 10 -10 g / ml γ-terpinene to prepare 2 groups of lures, one group absorbs these 6 components according to the ratio of 1:1:1:1:1:1 to make a mixture, upload it on the rubber head to make the lure called For the six-component lure, each rubber head was loaded with 250 μl of the mixture; the other group added 10 μl of liquid paraffin to the 250 μl of the six-component mixture as a slow-release agent, called the six-component slow-release lure. The lures of the two groups are all attached to the white round sticky boards, with a dia...

Abstract

The invention provides a method for trapping and killing empoasca vitis by using mint volatile matter. The empoasca vitis is used as test insects, six kinds of volatile matter of mint plants are used as smell sources, the six kinds of volatile matter comprise cis-3-hexenyl acetate, 3-octanone, caryophyllene, alpha-phellandrene, eucalyptol and gamma-terpinene, n-hexane is used as solvents to be prepared into trapping and killing agents according to the proportional combination being 1:0.112:0.1-12:0.1-12:0.1-12:0.1-12, the trapping and killing agents are carried with a rubber head to be made into a trapping core and attached to a bud green round sticky trap, and trapping and killing are performed at peaks of the empoasca vitis. According to the method, the weed mint volatile matter which is common in a tea garden is used for trapping and killing the empoasca vitis which is the most important injurious insects, the use amount of chemical pesticide is reduced, and the problems that drug resistance of the empoasca vitis occurs, pesticide residues of tea leaves exceed the standard, and the number of subordinate injurious insects is increased to cause rampancy are solved. The trapping and killing agents of the empoasca vitis are high in trapping efficiency, safe, free of pollution and compatible with the environment, the trapping speed is high, use is convenient, and cost is low.

Description

technical field [0001] The invention belongs to the field of plant protection. It involves the semiotic substances contained in the volatiles of mint, a weed in the tea garden, and screens out the components that have a significant attractant effect on the green leafhopper to form a fake-eyed green leafhopper attractant, adding an appropriate dose of liquid paraffin as a slow-release agent to form High-efficiency attractant for green leafhopper with false eyes; attach it to the green circular sticky board of buds, and apply it in tea gardens during the peak period of the leafhopper population and when the percentage of adults exceeds a certain number, good trapping and killing of the leafhopper can be obtained Effect. Background technique [0002] False-eyed green leafhopper Empoasca vitis It is one of the main pests on tea trees. It uses adults and nymphs to suck the juice of buds and leaves. The leaf margins of the injured buds and leaves turn yellow, and the veins turn...
