AI Technical Summary

Technical Problem

Existing methods for controlling the fourth instar nymphs of the bamboo oviduct bug have problems such as high workload, environmental pollution, and excessive human consumption, especially the drawbacks of chemical and physical control methods.

Method used

A trap for fourth-instar nymphs of the bamboo oval bug was designed. It is fixed in the bamboo forest using a pole, with a slow-release bottle filled with attractant on the top, and sticky insect boards distributed in a cross shape. The combination of attractant and repellent, along with the rotation and protective mechanism of the device, improves the trapping efficiency and avoids environmental pollution and labor consumption.

Benefits of technology

This method achieves efficient trapping of fourth-instar nymphs of the bamboo oviduct bug, reducing environmental pollution from chemical control and manpower consumption from physical control, and improving trapping efficiency and the practicality of the device.

Abstract

The application discloses a bamboo Dichelus quadernarius nymph trap, an attracting and avoiding agent and an application method, and belongs to the technical field of forest protection science, which comprises a plug rod, a socket is fixed to the top of the plug rod, a slow-release bottle is installed on the top of the socket, diffusion sponges are evenly arranged on the outer side of the plug rod in a circumferential direction, a drainage groove is arranged in the inner top of the plug rod and is used for conducting the bottom end of the slow-release bottle and the diffusion sponges, and a mounting disc is horizontally rotationally installed below the socket at the top of the plug rod. The plug rod is fixed and inserted into a bamboo forest, the slow-release bottle is arranged on the socket at the top of the plug rod, the inside of the slow-release bottle is filled with an attracting agent, target nymphs are attracted, and the cross-shaped glue boards distributed on the side of the plug rod can capture the attracted nymphs, so that the pollution of chemical control to the environment and the excessive consumption of manpower of physical control are avoided, in addition, the slow-release bottles containing the avoiding agent are placed between adjacent devices, the attracting agent and the avoiding agent are used in cooperation, and the trapping efficiency is improved.
