Embodiment 1

[0028] Embodiment 1: the preparation of the lure core of the adult attractant of the small green leafhopper with false eyes

[0029] 1) Preparation of Attractant for Leafhopper with False Eyes (volume parts)

[0030] Take 25 parts of cis-3-hexenol, 50 parts of cis-3-hexenol acetate, 30 parts of trans-β-ocimene, and 17 parts of (R)-(+)-limonene, and then mix them evenly, that is The adult attractant of the false-eyed green leafhopper was prepared and used for future use.

[0031] 2) Sustained release material preparation

[0032] The slow-release material is a sleeve-type silicone slow-release carrier. The carrier is 20 mm high and has an inner diameter of 0.5 mm. Soak the sleeve-type silicone slow-release carrier in ethanol for 5-10 days, replace the ethanol once a day, then rinse with distilled water until there is no ethanol smell, and finally dry it under natural conditions, and pack it into a sealed bag for use.

Embodiment 2

[0035] Embodiment 2: the preparation of the attractant lure core of the adult green leafhopper with false eyes

[0036] 1) Preparation of Attractant for Leafhopper with False Eyes (volume parts)

[0037] Take 20 parts of cis-3-hexenol, 44 parts of cis-3-hexenol acetate, 18 parts of trans-β-ocimene, and 12 parts of (R)-(+)-limonene, and then mix them evenly, that is The adult attractant of the false-eyed green leafhopper was prepared and used for future use.

[0038] 2) Sustained release material preparation

[0039] With the step 2 of embodiment 1.

[0040] 3) Attractant core preparation

[0041] Add the attractant prepared in step 1) dropwise to the slow-release carrier prepared in step 2), and add 20 μL of attractant dropwise to each slow-release carrier. Then pack it into a bag and seal it, and place it in a refrigerator at 4°C. Use after the attractant is completely absorbed by the slow-release carrier.

Embodiment 3

[0042] Embodiment 3: the preparation of the lure core of the adult attractant of the small green leafhopper with false eyes

[0043] 1) Preparation of Attractant for Leafhopper with False Eyes (volume parts)

[0044] Take 1.2 parts of cis-3-hexenol, 3.0 parts of cis-3-hexenol acetate, 0.75 parts of trans-β-ocimene, and 0.45 parts of (R)-(+)-limonene, and then mix them evenly, that is The adult attractant of the false-eyed green leafhopper was prepared and used for future use.

[0045] 2) Sustained release material preparation

[0046] With the step 2 of embodiment 1.

[0047] 3) Attractant core preparation

[0048] Add the attractant prepared in step 1) dropwise to the slow-release carrier prepared in step 2), and add 40 μL of attractant dropwise to each slow-release carrier. Then pack it into a bag and seal it, and place it in a refrigerator at 4°C. Use after the attractant is completely absorbed by the slow-release carrier.

Abstract

The invention discloses an Empoasca vitis adult attractant and belongs to the technical field of attractants. The Empoasca vitis adult attractant comprises, by volume, 0.2-100 parts of cis-3-hexen-1-ol, 1-220 parts of cis-3-hexenyl acetate, 0.5-50 parts of trans-beta-ocimene and 0.3-50 parts of (R)-(+)-limonene. The Empoasca vitis adult attractant can effectively trap Empoasca vitis so that centralized prevention and control are realized. The Empoasca vitis adult attractant is prepared by simple processes, has a low cost and is suitable for popularization application for tea garden plantation.

Description

technical field [0001] The invention belongs to the technical field of attractants, in particular to an attractant for adult green leafhoppers with false eyes. Background technique [0002] Leafhopper with false eyes Empoascavitis (G?the) is one of the important tea tree pests that occur seriously in tea areas in my country. It mainly uses adults and nymphs to suck the juice of tea tree shoots, and female insects will also lay eggs on the shoots, causing tea tree buds to yellow and curl. In severe cases, it will scorch and fall off, seriously affecting the yield and quality of tea. At present, the prevention and control of this false-eyed green leafhopper mainly depends on chemical pesticides. However, due to the strong fecundity of the insect and the serious overlapping of generations, frequent chemical control not only leads to the rapid increase of insecticide resistance, but also the problem of pesticide residues in tea is becoming more and more serious, which affects ...
