Abstract:So far as we know, 8 species of Lyctidae were reported in China: Lyctus brunneus (Stephens), L. africanus Lesne, L. sinensis Lesne, L. linearis (Goeze), Minthea rugieollis (Walker), Lyctoxylon japonum Reitter. Trogoxylon impressum Comdi and T. aequale (Walleston) S. jago. This paper deals with susceptibility of chinese hardwoods to powder-post beetles and presents a list of attacked woods which, include 39 families 103 genuses 168 species of tree but bamboo and rattan. Sapwood which contains an adequate amount of starch is attacked. Moreover it with large pore is more liable to infestation. The diameter of wood-vessels of 89.3% species of wood susceptible is more than 100μm. Minimum pore (<25.μm) woods and coniferous woods are not attacked, such as Aquifoliaceae. Theaceae. Hamamelidacece and Symplocaceae.Control methods:1. To remove the starch in sapwood, freshly felled wood or saw-lumber may be submerged in water for one year.2. Preventive treatment with boric acid or borax or spray with permethrin.3. Fumigation with methyl bromide (CH3Br) or sulphuryl fluoridc (F2O2S) at 40g/m34. Heating sterilisation with wood kiln.
