利用3年生黑松为接种材料,研究在9种不同真菌上取食的松材线虫的繁殖和致病力变化.结果表明,真菌对松材线虫的繁殖和致病力有显著影响.松材线虫在9种真菌上取食后,松材线虫繁殖力和致病力从大到小而依存的真菌依次为灰葡萄孢(Botrytis cinerea)、拟盘多毛孢(Pestalotiopsis sp.)、盘多毛孢(Pestalotia sp.)、拟茎点霉(Phomopsis sp.)、茎点霉(Phoma sp.)、头孢菌(Cephalosporium sp.)、交链孢(Alternaria sp.)、炭疽菌(Colle-totrichum sp.)、长喙壳(Ceratocystis sp.).实验表明松材线虫的繁殖力与其致病力变化相一致.

The variations of the reproduction of cultured Bursaphelenchus xylophilus on 9 different species of fungi and the pathogenicity on 3 years old Japanese black pine (Pinus thunbergii) were studied. The reproductions of the nema-todes on fungi was decreasing as the following fungal cultures of Botrytis cinerea, Pestalotiopsis sp. , Pestalotia sp. , Pho-mopsis sp. , Phoma sp. , Cephalosporium sp. , Alternaria sp. , Colletotrichum sp. and Ceratocystis sp.. The nematodes cultured on these fungi were inoculated on the seedlings of P. thunbergii and pathogenicity of B. xylophilus was decreasing as the same fungal culture sequence as the nematode reproduction. The variation in the pathogenicity of the B. xylophilus was consistent with the fungi repreductivity.
