Trapping device and method of empoasca vitis in tea garden

Abstract

The invention discloses a trapping device of empoasca vitis in a tea garden . The trapping device comprises an upper half ellipsoid, a connecting rod is fixedly connected to the spherical surface of the upper half ellipsoid, a lower half ellipsoid is fixedly connected to the other end of the connecting rod, the upper half ellipsoid and the lower half ellipsoid are mutually symmetrical, spherical surfaces are opposite, insect trapping lamps are uniformly arranged on the spherical surface of the upper half ellipsoid, a convergent spray pipe is arranged on the upper half ellipsoid in a penetrating manner, a central shaft of the convergent spray pipe is superposed with a central shaft of the lower half ellipsoid, an insect collecting box is connected to the end, far away from the upper half ellipsoid, of the convergent spray, and an axial flow fan is mounted under the insect collecting box. The invention further provides a trapping method of the empoasca vitis in the tea garden. The empoasca vitis as main injurious insects on a tea tree can be effectively trapped.

Description

technical field [0001] The invention belongs to the technical field of pest trapping devices, and relates to a trapping device for the false-eyed green leafhopper in tea gardens, and also relates to a trapping method for the false-eyed green leafhopper in tea gardens. 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%...

AI Technical Summary

Problems solved by technology

The above multiple methods have not combined the body shape of the small green leafhopper with false eyes (the adult body length is between 2 and 3mm, and the individual is tiny), the weak flight ability (the average flight distance is 4.7m), and the flight height (slightly higher than the tea branch tip), and is particularly sensitive to monochromatic light (420nm), whether it is a sticky board or a high-voltage power grid to kill, the trapping effect is not ideal
