Problems solved by technology

However, with the strict control of tea pesticide residues in our country, the use of green control methods has gradually become a necessary method for the control of small green leafhopper pests, such as: using green or yellow sticky boards for hunting, or using attractants combined with sticky boards. Although the lure effect of this kind of method is better than that of the common armyworm version, generally speaking, the current green control methods for small green leafhoppers generally have a series of shortcomings such as poor sustained and stable release effect, short release period, frequent replacement, and a lot of manpower and material resources.

Embodiment 1

[0017] Embodiment 1: tea small insect pheromone lure core is combined with yellow sticky insect board, and its lure core composition is by weight percentage hexenol 15%, ionone 28%, linalool 32%, vitamin E 3%, eugenol twenty two%. , the mixture prepared by the above components is dissolved in n-hexane solvent, added to the silicone rubber carrier, and after the solvent is completely volatilized, the tea leafhopper insect pheromone lure is made. The green leafhopper insect pheromone lure core is placed on a yellow sticky insect plate, and the wavelength of the yellow sticky insect plate is 385nm. When in use, insert the small green leafhopper lure into the central hole of the sticky insect board, fix the yellow board with a bracket, place it at a level with the tea tree, and hang the board facing east-west. The test area is 10 mu, and each mu of land 20 sets of hanging tea leafhopper lures and yellow boards.

Embodiment 2

[0018] Embodiment 2: tea small insect pheromone lure wick is combined with yellow sticky insect board, and its lure wick composition is calculated by mass percentage: hexenol 35%, ionone 22%, linalool 20%, antioxidant BHT5%, clove 18% phenol, the mixture prepared by the above-mentioned components was dissolved in ethyl acetate solvent, added to the silicone rubber carrier, and after the solvent was completely volatilized, the tea leafhopper insect pheromone lure was made. The green leafhopper insect pheromone lure core is placed on a yellow sticky insect plate, and the wavelength of the yellow sticky insect plate is 375nm. When in use, insert the small green leafhopper lure into the central hole of the sticky board, fix the yellow board with a bracket, place it at a level with the tea tree, and adjust the hanging position of the yellow board along with the tea tree. When hanging, adopt to hang the board toward the east-west direction, the test area is 10 mu, and every mu of la...

Abstract

The invention relates to a controlled-release type trap device for Empoasca flavescens, belonging to the field of pest control. The device mainly consists of an Empoasca flavescens insect pheromone bait and a sticky card, wherein the Empoasca flavescens insect pheromone comprises the following components by weight percent: 10%-45% of hexenol, 0.1%-40% of ionone, 5%-40% of linalool, 0.01%-10% of antioxidant and 5%-60% of eugenol, and the substances are mixed to 100%. According to the invention, the Empoasca flavescens insect pheromone is dissolved with normal hexane or ethyl acetate and then added to a rubber carrier so as to be prepared into the Empoasca flavescens insect pheromone bait, and the bait is matched with the special sticky card for use. Through using the device in the invention, the lasting trap capacity on the Empoasca flavescens can be improved, an insect attractant can be ensured to be stably released, and the use period is prolonged. The controlled-release type trap device for Empoasca flavescens has the advantage that the device is convenient and safe to use is environmentally-friendly and has no pollution.

Description

technical field [0001] The invention belongs to the field of pest trapping, and in particular relates to a slow-release trapping device for trapping small green leafhopper pests. Background technique [0002] Leafhopper is the primary pest of tea trees in my country. It mainly sucks tea leaves with adults and nymphs, which shortens the internodes of the damaged shoots, shrinks the buds and leaves, slows down or stops the growth of buds, and in severe cases, the buds and new leaves scorched and fell off, and even the new leaves were scorched and fell off. All the leaves fall off, which affects the yield and quality of tea. Due to their strong reproductive ability and lack of effective natural enemies, these pests have always been the number one tea tree pest in my country in recent years. They usually cause more than 10% reduction in tea production, and in severe cases can cause a 30%-50% reduction in production. At present, the prevention and control of small green leafhoppe...
