Problems solved by technology

However, the first and fourth rounds of tea bud germination are from mid-April to late May, and from mid-August to late October, which are spring tea and autumn tea harvesting seasons. The population density of tea aphids is very high, and it is impossible to apply pesticides. , the yield and quality of tea were seriously impaired

Embodiment 2

[0054] Example 2 The effect of the winged tea aphid repellent is significantly better than that of the single-component repellent

[0055] 1 Materials and methods

[0056] From 12:00 to 14:00 on September 8, 2019, a tea garden where tea aphids have seriously occurred over the years was selected in the tea area of ​​Anji County, Zhejiang Province. It was divided into 5 areas with a distance of 20m from each other. One repellent was placed in each area. Each area is 1 treatment, each treatment is 2 mu of tea garden, and 5 treatments are randomly set.

[0057] CK test area: with an area of ​​2 mu, 20 light green insect-attracting boards are placed, and the distance between the boards is 10m×15m. The bottom edge of each insect trap is slightly higher than the tea tip, and a rubber head containing 200 μL of n-hexane is tied on the tea branch in the tea bush 1-2m away from the insect trap, that is, the n-hexane core.

Abstract

The invention provides a method for trapping and killing winged tea aphids in the growing season in a push-pull manner by using a repellent and an attractant. The method comprises steps as follows: the tea aphid attractant with the dosage of 40-80 mg / mL is prepared from citronellol, phenethyl alcohol and limonene in proportion, and the tea aphid repellent with the dosage of 45-90 mg / mL is prepared from E-beta-farnesene, n-decanoic acid and n-octanal in proportion. In the growing season, the migratory flying and population full-emergence periods of the winged tea aphids are set from the middle ten days of April to the last ten days of May and from the middle ten days of August to the last ten days of October every year, rubber head cores loaded with the repellent are placed in tea clusters, and the winged tea aphids are driven to land on tea tips; and meanwhile, a light green insect trapping sticky plate with an attractant trapping core is fixed above the tea tips within the distance of 1-2 m, and the attractant and light green attractive force are overlaid to trap and kill the driven winged tea aphids. 8-12 sets of push-pull type trapping and killing combinations are placed per mu, so that the migratory diffused winged tea aphids are thoroughly killed, and effective green prevention and control are implemented.

Description

technical field [0001] The invention belongs to the field of plant protection, in particular to a push-pull method for trapping and killing the tea aphid in growing season by using a repellent and an attractant. Background technique [0002] The tea aphid Toxoptera aurantii (Boyer) is a piercing-sucking pest that is widely distributed in tea areas in my country and damages the tender shoots of tea trees. Both adults and nymphs suck the juice from the tender shoots of tea trees and excrete "honeydew" on the lower leaves. On the ground, smoke mold is bred, causing tea coal disease, and when it is serious, the tea garden will be dark, hindering photosynthesis. The young shoots are the raw material for processing high-grade tea. The commercial tea processed from the pricked and sucked tea shoots has low aroma and taste, darkened tea soup color, rough shape and amorphous shape, and the price drops. If pesticides are used to control aphids, a large amount of pesticides will remain...
