Embodiment 1

[0032] Embodiment 1: preparation of lure cores based on grape volatiles

[0033] 1) Preparation of the attractant for the false-eyed green leafhopper based on grape volatiles (parts by weight)

[0034] Weigh 10 parts of cis-3-hexene acetate, 9 parts of cis-3-hexene butyrate, 18 parts of 3,7-dimethyl-1,3,6-octatriene, 4,8-di 13 parts of methyl-1,3,7-nonatriene and 5 parts of ethyl benzoate were mixed evenly to prepare the adult attractant for the green leafhopper.

[0035] 2) Sustained release material preparation

[0036] 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.

[0037] 3) Attractant core preparation

[0038] Add the attrac...

Embodiment 2

[0039] Embodiment 2: preparation of lure cores based on grape volatiles

[0040] 1) Preparation of the attractant for the false-eyed green leafhopper based on grape volatiles (parts by weight)

[0041] Weigh 50 parts of cis-3-hexene acetate, 44 parts of cis-3-hexene butyrate, 108 parts of 3,7-dimethyl-1,3,6-octatriene, 4,8-di 60 parts of methyl-1,3,7-nonatriene and 18 parts of ethyl benzoate were mixed evenly to prepare the adult attractant for the green leafhopper.

[0042] 2) Sustained release material preparation

[0043] With the step 2 of embodiment 1.

[0044] 3) Attractant core preparation

[0045] Add the attractant prepared in step 1) dropwise to the slow-release carrier prepared in step 2), and add 50 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

[0046] Embodiment 3: preparation of lure core based on grape volatiles attractant for leafhopper with false eyes

[0047] 1) Preparation of the attractant for the false-eyed green leafhopper based on grape volatiles (parts by weight)

[0048] Weigh 1 part of cis-3-hexene acetate, 0.9 part of cis-3-hexene butyrate, 1.8 parts of 3,7-dimethyl-1,3,6-octatriene, 4,8-di 1.3 parts of methyl-1,3,7-nonatriene and 0.3 parts of ethyl benzoate were mixed evenly to prepare the adult attractant for Leptosphaeria spp., which is ready for use.

[0049] 2) Sustained release material preparation

[0050] With the step 2 of embodiment 1.

[0051] 3) Attractant core preparation

[0052] Add the attractant prepared in step 1) dropwise to the slow-release carrier prepared in step 2), and add 45 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 ca...

Abstract

The invention relates to an empoasca vitis gothe attractant based on a grape volatile matter and belongs to the technical field of trapping a large number of injurious insects by virtue of semiochemicals. The empoasca vitis gothe attractant based on the grape volatile matter comprises the following components in parts by weight: 1-120 parts of cis-3-hexylene acetate, 0.9-100 parts of cis-3-hexylene butyrate, 1.8-200 parts of 3,7-dimethyl-1,3,6-octatriene, 1.3-100 parts of 4,8-dimethyl-1,3,7-nonatriene and 0.3-60 parts of ethyl benzoate. The empoasca vitis gothe attractant prepared by utilizing the grape volatile matter is reasonable in compatibility, empoasca vitis gothe can be effectively trapped, and the aim of concentrated prevention and control is achieved, so that the empoasca vitis gothe attractant has a broad industrialization prospect.

Description

technical field [0001] The invention belongs to the technical field of trapping pests in large quantities through semiochemicals, and in particular relates to a fake-eyed green leafhopper attractant based on grape volatiles. Background technique [0002] The green leafhopper (Empoasca vitis Gothe) is an important pest that commonly occurs in tea areas in China. Adults and nymphs of the insect suck the juice of new shoots of tea trees, and the females lay eggs on the shoots, destroying the conduction tissue. After the tea tree is damaged, the buds and leaves will turn yellow, the veins will turn red, and the leaves will curl. In severe cases, the branches will be reddish brown and scorched. In the middle and lower reaches of the Yangtze River in my country, the loss of tea leaves in summer and autumn in normal years can reach 10-15% due to the damage of green leafhoppers, while the loss of tea leaves in severe disaster years is as high as 50%. At present, the occurrence and...
