Directional sound control device for controlling tea lesser leafhopper

Abstract

The invention discloses a directional sound control device for controlling tea lesser leafhopper. The directional sound control device comprises a fixed flange 1, a protective net cover 2, a T-shaped strain gauge 3, a sound wave reflecting cover 4, a sound wave transmitting array 5, a sound absorbing plate 6, a self-pressure-relief sound barrier 7, an antenna 8 and a control circuit 9. Through the scientific design of the structure of the strong-directivity sound wave emission array 5, the reflecting cover body 4, the sound absorbing plate 6 and the self-pressure-relief leaf plate sound barrier 7, good sound wave forward emission and backward transmission inhibition performance is achieved, and sound absorption peak frequency migration can be achieved by adjusting the aperture of the sound absorbing plate 6. The directional sound control device for controlling the tea lesser leafhopper solves the habitat problem that existing equipment affects tea garden construction, tea garden management personnel and nearby resident life, and the environment-friendly directional sound control method for controlling the tea lesser leafhopper in the tea garden is formed.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of agricultural diseases and insect pests, and in particular relates to a directional sound control device for preventing and controlling tea leafhoppers. Background technique [0002] Tea green leafhopper is one of the main pests in my country's tea gardens. The insect generally hides in the back of leaves and does damage, and is more common in young shoots and weeds. Tea gardens with unreasonable intercropping are most likely to occur, and disasters are most likely to occur under the weather conditions of sometimes sunny and sometimes rainy. Tea leafhoppers usually have 8 to 10 generations per year, and the damage lasts for a long time (the main damage period is from May to September every year). They use adults and nymphs to suck the juice of young tea tree shoots, consume nutrients and water, and females lay eggs on the young shoots. In the tissue, the growth of buds is hindere...
