초록

Thermal death kinetics was examined to develop a heat treatment method to control the Alnus ambrosia beetle, Xylosandrus germanus, in wood packing materials for export goods. To determine the feasibility of microwave irradiation as an alternative treatment, we performed laboratory experiments on the blocks (200x200x250mm) of Douglas-fir artificially infested with live adults with subsequent 2.45GHz microwave energy irradiation. The 100% mortality of treated Alnus Ambrosia Beetle was achieved above 58℃ of the measured wood temperature, regardless of irradiated time. All measurement points in the blocks reached 58℃ within 84-312 seconds with microwave irradiation by wood weight. Likewise, the 100% mortality of breetles were observed by hot water treatment on 52℃. We need further experimental verification, but commercial microwave (2.45GHz) treatment is a feasible alternative to conventional heat treatment to control Alnus ambrosia beetle on the wood packing materials for export goods.
