Embodiment 1

[0021] see figure 1 , a kind of trapping device for tea geometrid braconids of the present invention is realized through the following technical solutions:

[0022] (1) Choose nerol, n-pentanol, n-hexanal, cis-3-hexenyl acetate and methyl salicylate as flavor sources, and configure the concentration to be 10 -7 g / ml~10 -1 g / ml, and then formulate the velvet wasp attractant according to the ratio of 1:0.1~15:0.1~15:0.1~15:0.1~15, inject the attractant into the rubber head to make the lure a, the rubber head used It is made by rinsing natural rubber with an organic solvent, which can be rinsed with absolute ethanol, washed to remove impurities, and dried;

[0023] (2) Adopt the color that has stronger lure effect to the tea geometrid cocoons, make colored ball b, used color is selected from bud green, parrot green, tender green, jasmine yellow, olive yellow green, chalcedony green, malachite green, Blue-green, dark green, jasmine yellow and snow white. Preferably tender gree...

[0028] Determination of Flavor Sources with Strong Attractive Activity by Bioassay

[0029] 1. Behavioral responses performed by the "Y"-shaped olfactometer

[0030] The length of the two arms and the base of the "Y"-shaped tube is 10cm, and the angle between the two arms is 90°, which is sequentially connected with a flavor source bottle (or a control bottle), a distilled water bottle, and a molecular sieve. With liquid paraffin, 15 main components are formulated into solutions respectively as flavor sources, and the concentration is 10 -7 g / ml-10 -1 g / ml, and then take liquid paraffin as a control. Use an open 2ml Anbei bottle to put 1ml of the flavor source in the taste source bottle, and put 1ml of liquid paraffin in the control bottle, pump air from the base of the Y tube with a vacuum pump, and the natural air will be filtered through molecular sieves, humidified by a distilled water bottle, and flavored. The source vial (or control vial), where the arms of the Y tube...

Embodiment 3

[0035] The tea garden community test determines the color with strong allure

[0036] Make 11 colored balls of bud green, parrot green, light green, jasmine yellow, olive yellow green, chalcedony green, malachite green, blue green, dark green, jasmine yellow and snow white, apply colorless and odorless insect glue evenly on the spherical surface, and place them in the tea garden To lure and stick to catch tea geometrid velvet wasps. In mid-July 2002, the test was conducted in the tea garden of Magu Mountain Tea Farm in Anhui Province. The tea geometrid population in this test tea garden has been heavy over the years. After 48 hours, the number of velvet wasps trapped by the three colored balls of light green, bud green and parrot green was ≥8.0 head (the number of repetitions is 20), the number of wasps trapped by other colored balls <5.0 heads. It shows that the lure effects of light green, bud green and parrot green colored balls are better.

Abstract

The invention discloses a method for attracting tea geometrid moth and suede cocoon bee, comprising: separating and identifying ten kinds of volatile matter from the volatile matter in the tea damaged by the tea geometrid moth and from the camellia scent by applying method of top fluidizing adsorption; choosing components with strong attracting active for the tea geometrid moth and suede cocoon bee through the behavior detecting and physiological research of the insect antenna electricity; preparing scent source matter with active components; preparing the attracting agent according to a certain proportion; choosing colors with strong attracting effect to the tea geometrid moth and suede cocoon bee by the attracting experiment in the tea area and producing color ball. Suspending the attracting chip injected with attracting agent in the color ball and preparing for attracting device, putting which in the field to attract the tea geometrid moth and suede cocoon bee, which can deduce the use of chemical pesticide. The invention is characterized by the following aspects: attracting the suede cocoon bee in the small environment in a short time, which uses the parasitic wasp with a high efficiency to control the tea geometrid moth, deducing the chemical protection; free of pollution which is helpful for the high effective ecological tea development; and the simple utilization and low cost.

Description

technical field [0001] The invention relates to a method for trapping the tea geometrid velvet wasp. Background technique [0002] Since the 1970s, the tea inchworm Ectropis oblique Prout has been rampant in Zhejiang, Jiangsu, and Anhui tea areas, and has gradually expanded to other tea areas. It belongs to Insecta (Insecta) Lepidoptera (Lepidoptera) Geometridae (Geometridae). It has 6-7 generations in Zhejiang Province and 5-6 generations in Jiangsu, Anhui and Jiangxi. When it is serious, it also chews on adult leaves and old leaves, and even eats bark. According to the survey, many state-run tea farms and tea farmers' family tea farms apply pesticides 7 to 10 times a year to prevent and control tea inchworms. Excessive use of chemical pesticides for decades has killed natural enemies in large quantities, reduced the biodiversity of tea gardens, and caused tea pesticide residues that once affected healthy drinking and tea exports; moreover, the pests have strong resistanc...
