Embodiment 1

[0028] The first step is the test of rosemary smell to lure the small green leafhopper with false eyes

[0029] 1. Flavor source

[0030] Rosemary Rosmarinus officinalis L. is a weed that grows naturally in the tea garden of China Jiliang University. During the experiment, the young part was cut as a flavor source material to release the smell to attract the green leafhopper with false eyes. A total of 6 doses of 1g, 2g, 3g, 5g, 7g, and 9g were set up, and each dose was tested 5 times.

[0031] 2. Insects to be tested

[0032] The female and male adult green leafhoppers with false eyes were collected from the tea garden of China Jiliang University, and they were raised on potted tea trees in insect cages, allowing them to mate and lay eggs freely. When the eggs hatch and grow into 3rd instar nymphs, they are used as test insects. Half an hour before the test, the 3rd instar nymphs were taken and stored in test tubes for later use, and they were fasted.

[0033] 3. Y-shape ...

Embodiment 2

[0088] Example 2 Time rhythm of leafhoppers flying to five-component lures in tea gardens

[0089] 1, adopt 4 kinds of lures in the 5th step of embodiment 1, attach to the jasmine yellow sticky board respectively, carry out the test in the tea garden with reference to the 5th step procedure, every kind of lure repeats 30 times. Divide a day into the following 7 time periods: 18:00-6:00, 6:00-8:00, 8:00-10:00, 10:00-12:00, 12:00-14:00, 14:00-16:00 and 16:00-18:00. The number of leafhoppers on the swatches was surveyed in the last 30 minutes of each session. From July 21st to July 26th, a 6-day time rhythm survey was conducted.

[0090] The difference between the number of leafhoppers trapped by each lure in 7 time periods per day was analyzed by variance, and the difference was compared by Duncan’s new multiple range, which proved that the lure effect of the five-component lure in rosemary smell was significant.

Embodiment 3

[0093] Example 3 The control effect of rosemary odor six-component lure in the field for the small green leafhopper with false eyes

[0094] 1. In the tea area of ​​Anhui Province, early September to late November is the peak period for the population of Leafhopper with false eyes. On September 8, the tea plantation of Magushan tea farm in southern Anhui was selected to produce tea. Setting: 20 six-component lures + jasmine yellow sticky boards / 667m 2 ;Treatment 2: 20 Blend2 lures + jasmine yellow sticky boards / 667m 2 ;Treatment 3: 20 n-hexane lures + jasmine yellow sticky boards / 667m 2 ;treatment 4: 0 traps / 667m 2 Namely CK. Each lure is repeated 3 times, and the area of ​​each repetition is 667m 2 tea garden.

[0095] From 10:00 am to 12:00 am on September 8, samples were taken at 5 points in 12 plots with 4 treatments, and a 1-meter tea row was taken from each sample point, divided into two longitudinally, and the tea branches were patted vigorously, covered with a pla...

Abstract

The invention provides a method for trapping empoasca vitis gothe by means of tea plantation weed rosemary smell. The rosemary smell is used as a smell source, five kinds of components of the rosemary smell are mixed to prepare an empoasca vitis gothe trapping agent, the trapping agent is loaded to a rubber head to form a trapping core which is attached to a jasmine yellow glue board, trapping is conducted during the leafhopper peak period, and the tapping agent has the good trapping effect on the empoasca vitis gothe. According to the method, the plant smell of a tea plantation ecosystem is used for trapping the empoasca vitis gothe, so that the environment is protected, and biological diversity is not damaged. The plant smell is used for trapping, preventing and controlling the empoasca vitis gothe, and using frequency and dosage of chemical pesticide are reduced. The method is simple and convenient to implement, and low in cost. The prepared empoasca vitis gothe trapping agent is high in trapping efficiency, high in trapping speed, stable in performance, and capable of effectively trapping the empoasca vitis gothe, and the preventing and controlling effect reaches 60%.

Description

technical field [0001] The invention belongs to a method for preventing and controlling tea tree pests, and relates to semiotic substances contained in the smell of rosemary, a weed in tea gardens. These semiotic substances are screened out to form a false-eyed green leafhopper attractant, and an appropriate dose of synergist and slow-release agent is added. Composition of a high-efficiency attractant for the green leafhopper with false eyes; attaching it to a jasmine yellow sticky board, and applying it in tea gardens during the peak population period of the leafhopper and when the percentage of adults exceeds a certain number can obtain a good control effect on the leafhopper. Background technique [0002] Leafhopper with false eyes It is the most serious pest in Chinese tea gardens so far. It damages the young shoots of tea trees by piercing and sucking by adults and nymphs; the female insects lay eggs in the tender stems, destroying the transporting tissue of the tender...
