AI Technical Summary

Technical Problem

Existing physical trapping devices are not very effective at trapping underground pests that have been hiding in the soil for a long time, making it difficult to effectively control the population of pests. Furthermore, chemical control methods lead to soil pollution and increased pesticide resistance in pests.

Method used

A trapping device for underground pests in potato growing areas is designed, including a trapping tube, an attractant box, and a conical guide tube. The device uses odor diffusion to attract pests into the trapping chamber and guides them into the collection chamber through the conical guide tube to prevent them from escaping. The device has a simple structure and is easy to operate.

Benefits of technology

It effectively captures pests hiding in the soil, reduces the use of chemical pesticides, protects the soil ecological environment, and improves the control effect of underground pests.
