“…Alternatively, specific drying cycles are used as sanitization treatments (Ananías and Venegas 2005;Ananías et al 2013). Because of the time it takes to reach the target temperature, dielectric heating at radio frequencies (RF) has been used as an alternative to sanitize wood and eliminate Bursaphelenchus xylophilus and other nematodes (Lăzărescu et al 2011;Uzunovic et al 2013;Lăzărescu et al 2015). For effective sanitization, a minimum temperature of 60 °C must be achieved and maintained for at least for 1 min at the center of the wood, as shown by Hoover et al (2010).…”

A treatment is proposed to sanitize wood for export packaging using radio frequency equipment that is capable of treating wood. This was achieved by optimizing the sanitization process and developing an equation to predict the total sanitization time. Statistical analysis determined that the separation of plates and the power density of the equipment significantly influenced the duration of a sanitization process using radio frequency heating, whereas the thickness of the material was not as influential for the overall process. Furthermore, the sanitization process did not influence the quality of the wood; therefore, the proposed sanitization protocol provided a balance between duration and the quality of the finished radiata pine packaging material.

“…In Germany, the damage caused by dry rot fungus ( Serpula lacrymans ) alone adds up to 200 million € a −1 . State‐of‐the‐art pest control focuses on chemical as well as physical methods . However, in recent years the application of chemical wood preservatives in living and working areas has been declining to avoid the contamination of indoor air.…”

Chemical‐Free Pest Control by Dielectric Heating with Radio Waves and Microwaves: Thermal Effects

et al. 2017

Thermal pest control with hot air is widely accepted as an alternative to chemical methods. However, it requires relatively long treatment times owing to the low thermal conductivity of wood. Direct dielectric heating that applies radio waves or microwaves has the advantage of more homogeneous heating. However, sound experimental data on this technique are currently rare. Therefore, the thermal treatment of wood-destroying insects with radio waves and microwaves was studied with two model pests, Anobium punctatum and Hylotrupes bajulus, and with Tenebrio molitor as a reference. The secure elimination of pests was achieved, and the corresponding treatment time was in the range of a few minutes. Temperature profiles were more homogeneous when applying radio waves.

“…Thus, there is significant need for new non-chemical based alternative treatments. Dielectric heating both a radio and microwave frequency levels was tested with positive results for green logs, timbers and packaging materials thus leading to its adoption as substitute treatment (Lazarescu et al 2010, Hoover et al 2010, Uzunovic et al 2013, Lazarescu et al 2015.…”

Pinewood nematode (Bursaphelenchus xylophilus) mortality was investigated after ultrasonic treatment at 20 and 40 kHz frequency. Experiments were conducted with infected small wood specimens that were ultrasonically treated for 1, 3, 5 and 7 hours and two variable temperature conditions, namely, a gradually increasing from ambient to a maximum of 70 o C and a decreasing from ambient to a minimum of 5 o C. The results revealed that the ultrasonic treatment itself had no significant effect on the nematode mortality at the 5 o C level, while at the 70 o C level, considerable nematode mortality was observed in short time periods and at 7 hours of sonic exposure it reached 100%. Therefore, certain combinations of timing and frequency of ultrasonic waves and produced heat can be effective in killing pinewood nematodes thus resulting in phytosanitized wood.
