研究了黑松（ Pinus thunbergii）木屑不同含水量对松材线虫（ Bursahpe lenchus xylohp ilus）繁殖的影响，确定了适于线虫繁殖的最佳含水量，并以黑松木屑作为试验介质，模拟松材线虫生活条件，测定了杀线剂α-三噻吩（α-T）对松材线虫的毒力。结果表明：当黑松木屑相对含水量达到50％时最有利于松材线虫繁殖；α-T对松材线虫具有非常强的毒性，毒力回归方程为Y＝14．589＋18．720x，半致死质量分数为1．892μgg/。

An experiment was conducted to measure nematicidal activity of pine wood nematodes ( Bursaphle enchus xylophilus) with sawdust of black pine ( Pinus thunbergii) , and determine the best relative water content ( RWC) of the sawdustto culture pine wood nematodes and bioassay the nematicidal activity of α-T by the method.50% of RWC is best suitable condition toculture pine wood nematodes, and bythe regression equation of α-T against pine wood nematodes under the light intensity of 10 000 Lux, the toxicity regression equation is Y=14.589+18.720x, and the medial lethal concentration is LC50=1.892μg/g.
