To meet industry needs, promote organic and eco-friendly farming, and advance the plan for organic farming development in Hualien and Taitung, the TTDARES held the Eco-friendly Longicorn Beetle Control Technology Seminar on the morning of May 10, 2023 at the Binlang orchard of the TTDARES Banchiu Branch Station. The event began with a description of the habits of white-spotted longicorn beetles and how they harm trees before discussing common control measures. One measure discussed was the use of a high-pressure air gun, including equipment needed, how to use it, and results from those who have used it. The organic orchard management research team demonstrated its use on navel orange trees and allowed participants to try it out. The equipment is easy to use and costs little but is highly effective and safe for the environment, so it is perfect for organic farming. If used on non-organic farms, it can allow growers to use fewer pesticides and thus reduce pollution to the environment, so it is a tool worth consideration by both conventional and organic growers.
