摘　　要： 采用浸渍法在室内测定了在不同质量浓度和时间处理下4种化学药剂对松材线虫、阿苏里伞滑刃线虫的毒力。结果表明:阿维·苏云菌对这两种线虫的毒力最强,其最高浓度(50.00 g/L)处理松材线虫和阿苏里伞滑刃线虫48 h后,线虫的死亡率分别达85.67%、95.00%,半致死浓度(LC50)分别是20.80、12.88 g/L;克百威·敌和丁硫·毒死蜱对两种线虫也具有一定的毒力。 The indoor toxicities of different mass concentrations of 4 chemical nematicides against Bursaphelenchus xylophilus and Bursaphelenchus arthuri were tested by using dipping method. The results showed that： Abamectin·Bacillus thuringiensis had the strongest toxicity to these two nematode species,the mortality of B. xylophilus and B. arthuri reached 85.67% and 95.00% respectively 48 h after being treated with the highest concentration（50.00 g/L） of this nematicide,and their medial lethal concentration was 20.80 and 12.88 g/L separately; Carbofuran·Trichlorfon and Carbosulfan·Chlorpyrifos also had a certain toxicity to these two nematode species.
