Embodiment 1

[0014] Example 1 Attractive effect of three kinds of tea tree tissue odors on the leafhopper A. triclata

[0015] In the tea tree bonsai field of China Metrology Institute, more than 10 5-year-old tea trees were selected, connected with small green leafhoppers with false eyes, and covered with 60-mesh gauze to prevent the leafhoppers from escaping. After 10 hours of leafhopper damage: leaf-cutters suck and the tender stems stabbed by the ovipositor; cut off the buds and leaves that are sucked by leafhoppers; cut off the healthy tea leaves that are adjacent to the buds and leaves that are sucked by leafhoppers. The leafhopper wasp wasp was used as the test insect, and the behavior was determined by using a Y-shaped olfactometer. The quality of these three kinds of plant tissue odor sources were 1g, 2g, 3g, 4g, 5g and 6g respectively, and the clean air was used as CK in the indoor behavior measurement.

[0016] Compared with the air control, the green tea leaf punctured by the ...

Embodiment 2

[0017] Example 2 The effect of 27 kinds of volatiles originating from 3 kinds of tea tree tissue odors in attracting leafhopper wasps

[0018] Using Super Q as the adsorbent, the conventional dynamic adsorption method was used to adsorb the healthy tea odors of "Example 1" from stabbing tender stems, leafhopper needles sucking bud leaves, and stabbing and sucking bud leaves. MS and other instruments were used to measure the volatile compounds, and 27 main components were selected to prepare 10 -2 g / mL, 10 -4 g / mL and 10 -6 The solution of the g / mL dose, with reference to the method of "embodiment 1", carried out the behavior measurement to the leafhopper three-clad wasp, χ 2 The method was used to test the significant difference between the number of bees that chose the smell source and the number of bees that chose the clean air. The results are shown in Table 1.

[0019] Table 1 Attractive effect of three doses of 29 kinds of tea shoot volatiles measured by Y tube on the ...

Embodiment 3

[0025] Embodiment 3 The trapping agent of the present invention is compared with the effect of other 3 kinds of trapping agents

[0026] According to the result of "Example 2", the six-component attractant of the present invention is prepared as in Table 2, and the other three attractants are composed

[0027] Table 2 Differences in the composition of the attractant of the present invention and other three kinds of attractants

[0028]

[0029] There are significant differences. Take 100 μl of each attractant, load it on wool felt, add 1 mg of antioxidant 2,6-di-tert-butyl-4-methylphenol, seal the wool felt with polyvinyl chloride plastic, and make a lure core. Select a pollution-free tea garden in Yejiawan, Xuancheng City, Anhui Province. From 9 to 11 am on September 30, 2013, use six-component lures, three-component lures, α-terpinene lures and n-hexane lures. wicks, and frangipani yellow boards. 1 lure core is attached to a jasmine yellow board with a small piece of t...

Abstract

The invention provides a making method for a Stethynium empoascae Subba Rao attractant. The attractant is formed by combination of tea shoot volatile nerol, n-pentanol, alpha-terpinene and careen six components in certain proportion, and is loaded on a wool felt to make a lure core. The dose of each component is 10<-2>g / mL-10<-6>g / mL, and each lure core contains the six information-substances with a total volume of 100-200 microliters. Usually, during September to November every year, the Empoasca vitis Gothe population in tea garden enter the autumn peak season, and have substantial damage to tea, the dominant natural enemy Stethynium empoascae Subba Rao increases significantly in number, in the full incidence beginning period, a large number of Stethynium empoascae Subba Rao are attracted by the attractant to parasitize Empoasca vitis Gothe eggs so as to greatly enhance the natural parasitic rate, lower the Empoasca vitis Gothe Empoasca vitis Gothe, and reduce chemical control. The attractant does not pollute the environment, has no residue, and is beneficial to protection and utilization of tea garden biodiversity.

Description

technical field [0001] The invention belongs to the field of plant protection, and relates to a preparation method of an attractant for the leafhopper Tricladidae and its application in tea gardens to lure the leafhopper Tricladina parasitic false-eyed green leafhopper. Background technique [0002] False-eyed green leafhopper Empoasca vitis It is the most serious pest in the tea areas of mainland my country, causing 15%-20% reduction in tea production all year round. It needs to be controlled more than 10 times a year, and nearly 20 times in individual tea areas. In recent years, it has been found that the leafhopper Leptosphaera parasitica parasitizes the eggs of the green leafhopper with false eyes. The parasitism rate in many tea gardens in Hangzhou area reaches 16%-48% in summer and autumn, and the parasitism rate reaches 50%-75% in September. The leafhopper, Tricladidae, can be seen in tea gardens all the year round, and its parasitism rate is as high as 40%-65% duri...
