Problems solved by technology

The scientific names of these two bees were identified by Professor Lin Naiquan, so far there is no report on the breeding and breeding of these two bees; and under natural conditions, the natural population of these two bees is not enough to control the leafhopper

Embodiment 1

[0024] Example 1 Developing an attractant and trying it to attract wasps and control the green leafhopper with false eyes

[0025] Step 1: Separation and identification of volatiles from healthy and cicada-damaged tea plants and volatiles from healthy and oviposition-damaged tea plants

[0026] Put the above-ground parts of potted healthy tea tree plants, the above-ground parts of leafhopper-sucked tea tree plants, healthy tender stems, and tender stems stabbed by ovipositors into clean glass covers, and clean air is introduced from the air inlet to entrain The tea tree odor flows through the Super Q adsorption column connected to the air outlet, and the dynamic adsorption is 8 After 10 hours, the adsorption column was rinsed with chromatographically pure dichloromethane, and the eluate was slowly concentrated to about 20 μl under high-purity nitrogen flow. Draw 1μl and analyze it by gas-mass spectrometer, cooperate with the standard sample for qualitative determination...

Embodiment 2

[0043] Example 2 Detection of the attractiveness of tea tree mutene to the wasps

[0044] 1 Detection method

[0045] Using n-hexane as solvent, prepare 10 - 2 g / ml dosage α -farnesene, benzaldehyde, trans-2-hexenal, β -Farnesene, methyl salicylate and cis-jasmone solution, with n-hexane as a contrast, get an equal amount of benzaldehyde solution and cis-jasmone solution to form a mixture. Soak 1 bud and 2 tea leaves imitated by rubber materials in these 8 kinds of solutions for 24 hours, take them out and dry them in the air to make lures.

[0046] The number of bees gradually increased in autumn. The Meijiawu Village, the origin of West Lake Longjing in Hangzhou City, was selected for the experiment on September 11, 2010. Each lure was placed in the tea garden from 10:30 to 12:30, and each lure The core is attached to a sheet of 20 cm 40 cm bud green sticky board, there is no lure on the other side of the color board, the color board is tied to a small bamboo po...

Embodiment 3

[0051] Example 3 Detecting attractants to increase the parasitism rate of the wasps to the eggs of Leafhopper chrysalis

[0052] 1 Detection method

[0053] On October 3, 2010, in the organic tea garden in the Jingting Mountain Scenic Area of ​​the Jingting Mountain Tea Farm in Anhui Province, Leafhoppers Tricotidae and Tiny Craniospermia have been harvested. Then this piece of organic tea garden is divided into two parts, the area of ​​the upwind part is about 5 667m 2 , as a trapping area, the area of ​​the other part of the downwind vent is about 5 667m 2 As the CK area, no lures are placed, and the distance is 300 m.

[0054] On the morning of October 3, 1-bud and 5-leaf tea shoots with egg-laying thorns on the surface of the tender stems were randomly cut from the two tea gardens, and returned to the room. on moistened filter paper in a large Petri dish placed in a light incubator. Light incubator temperature 25 ± 3 ℃, relative humidity 70 ± 5%, light 32000 ...

Abstract

The invention provides a method for trapping mymaridae parasitized empoasca vitis. The method comprises the following steps of: preparing a trapping agent by taking four synomones, i.e., alpha-farnesene, cis-jasmone, methyl salicylate and benzaldehyde as taste sources; emulating tea shoot with one bud and two leaves by using rubber; soaking into the trapping agent for serving as a lure; and putting the lure into a tea garden at the growing start period, growing period and growing end period of an empoasca vitis population for trapping the mymaridae parasitized empoasca vitis. In the invention, the trapping agent is prepared from high-activity synomones for trapping mymaridae in the natural environment of the tea garden and suppressing empoasca vitis, so that chemical prevention and control are avoided. The method has the advantages of environmental friendliness, freeness from nuisance, accordance with the national green prevention and control principle, contribution to protecting and utilizing the natural enemy resources, capability of promoting the development of the organic tea industry, accordance with the building requirement on a standard ecological tea garden in the Ministryof Agriculture, easiness and convenience for operating, quick response, low cost and suitability for popularizing and applying.

Description

technical field [0001] The invention belongs to a method for preventing and controlling pests in tea gardens, and relates to a method for luring the wasps to parasitize the false-eyed green leafhoppers, and in particular to a method of using tea tree mutene to lure and guide the leafhoppers and the tiny rifts. A method for bees to parasitize the eggs of the important pest Leafhopper chrysalis. It involves the separation and identification of mutatis released from tea shoots that are damaged by leafhopper needles and inhalation, and tea shoots that are stabbed by leafhopper oviposition tubes. Collecting agent; use rubber to imitate tea tips with 1 bud and 2 leaves, and add a wasp attractant to make a lure; use the lure to lure and guide the green leafhopper at the beginning, peak and end of the leafhopper. Two species of wasps forage and parasitize the green leafhopper with false eyes. Background technique [0002] For decades, the false-eyed green leafhopper Empoasca viti...
