Embodiment 1

[0028] Embodiment 1: the preparation of lure core based on the lure core of the false-eyed leafhopper attractant based on peach tree volatiles

[0029] 1) Preparation of the attractant for the false-eyed green leafhopper based on peach tree volatiles (parts by weight)

[0030] Weigh 20 parts of benzaldehyde, 12 parts of cis-3-hexene acetate, 5 parts of 3,7-dimethyl-1,3,6-octatriene, 4,8-dimethyl-1,3 , 4 parts of 7-nonatriene, and then mixed evenly to prepare the adult attractant of the false eye leafhopper, which is set aside.

[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. The sleeve-type silica gel slow-release carrier was soaked in ethanol for 10 days, and the ethanol was replaced every 2 days. Then dry it in a blast drying oven at 60°C, pack it into bags and seal it for later use.

Embodiment 2

[0039] Embodiment 2: the preparation of lure core based on the lure core of the false-eyed green leafhopper attractant based on peach tree volatiles

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

[0041] Weigh 100 parts of benzaldehyde, 30 parts of cis-3-hexene acetate, 20 parts of 3,7-dimethyl-1,3,6-octatriene, 4,8-dimethyl-1,3 , 30 parts of 7-nonatriene, and then mixed evenly to prepare the adult attractant of the false eye green leafhopper, which is set aside.

[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.

[0050] Embodiment 3: based on peach tree volatiles lure core preparation of false-eyed leafhopper attractant

[0051] 1) Preparation of the attractant for the false-eyed green leafhopper based on peach tree volatiles (parts by weight)

[0052] Weigh 1 part of benzaldehyde, 0.1 part of cis-3-hexene acetate, 0.5 part of 3,7-dimethyl-1,3,6-octatriene, 4,8-dimethyl-1,3 , 0.1 part of 7-nonatriene, and then mixed uniformly to prepare the adult attractant of the false eye leafhopper, which is set aside.

[0053] 2) Sustained release material preparation

[0054] With the step 2 of embodiment 1.

[0055] 3) Attractant core preparation

[0056] 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.

Abstract

The invention discloses an empoasca vitis gothe attractant based on a peach tree volatile matter and belongs to the technical field of massively inducing pests through semiochemicals. The empoasca vitis gothe attractant comprises the following components including, by weight, 1-100 parts of benzaldehyde, 0.1-30 parts of cis-3-hexenyl acetate, 0.5-20 parts of 3,7-dimethyl-1,3,6- octatriene and 0.1-30 parts of 4,8-dimethyl-1,3,7-nitrophenol. According to the empoasca vitis gothe attractant based on the peach tree volatile matter, the artificially-synthesized volatile matter serves as a main raw material, the compatibility is reasonable, the attractive effect on empoasca vitis gothe imagoes is obvious, the empoasca vitis gothe can be effectively trapped, and therefore the goal of centralized prevention and treatment is achieved. The empoasca vitis gothe attractant based on the peach tree volatile matter has the advantages that use is convenient, and no pollution exists. Accordingly, the wide industrialization prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of trapping pests in large quantities through semiochemicals, and in particular relates to an attractant for the false-eyed green leafhopper based on peach tree volatiles. Background technique [0002] Leafhopper with false eyes ( Empoascavitis G?the) is a major pest of tea trees in my country. 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. When it is seriously damaged, the tea tree branches will be reddish brown and scorched, and the growth of buds and leaves will be stagnant and fall off, which will have a great impact on the yield and quality of tea. In the tea areas in the middle and lower reaches of the Yangtze River in my country, the loss of summer and autumn tea is usually up to 10-15% due to the damage of the small green leafhopper with false eyes, and the loss in the severe disaster year is as hi...
