Wood-Boring Insect Control in Constructions by High Temperature and Microwaves
The chapter focusses on the control wood boring insects in constructions. The influence of temperature in the range of 50–65°C was studied for the larvae of Hylotrupes bajulus L. Attempt is made to clarify the influence of high temperature on the larvae in the context of the different results in the former German publications. The paper presents too the conditions in which the insects, which are technical pest to timber, can be combated by the use of high air temperature and microwaves 12,2cm length (2,45GHz) and which are emitted in the form of scattered field. In the experiments two prototype microwave devices ware used, their power being 600W and 1400–2400W, as well as one microwave chamber whose power was 1000 W. Laboratory results of author were presented against the designer results obtained with other insect species and the results in the recent publications by other authors. The aim of this work is to present the results of the author’s microwaves research and some problems in practice. Additional experiments were conducted on polychrome and gilded timber as well as the timber into which two-inch steel nails had been driven. The study included the possibility of melting wood resin.
