摘　　要：Bioassay of 51 strains of Bacillus thuringiensis to Bursaphelenchus xylophilus had been studied in laboratory. Two of them had higher toxicity to B. xylophilus. Extraction of endotoxin and exotoxin of the two isolates to B. xylophilus showed the action of exotoxin higher than that of endotoxin.Bioassay of 51 strains of Bacillus thuringiensis to Bursaphelenchus xylophilus had been studied in laboratory.
