危害橡胶木的真菌和昆虫

林业科学研究 2001年第2期14卷 230-235页

作者：邢嘉琪中国林业科学研究院木材工业研究所北京100091

The biological characteristics of the insects and fungi which seriously attack rubberwood and the present state of rubberwood biodeterioration in China were described. The fungi attaching rubberwood consist mainly of blue stain fungi, moulds and rotting fungi. The insects include beetle borers, termites and some other Coleopteran species, such as longicorns and snout beetles etc., the total insect species are near to one hundred. The stain fungi, moulds and beetles should be paid more attention to in rubberwood preservation.
