Abstract:
Survival rate of Bursaphelenchus xylophilus were studied in different moistures of woody packaging material. The results were as follows: As processing time, the survival rate of nematode was declining for wood with different moisture at 25 ℃ and 4 ℃; wood with 12.0 %—22.8 % moisture, in which survival rate of nematode was significantly lower than without dried wood with 34.4 %—48.0 % moisture. After 6 hours treatment, wood with 12.3 % moisture,which was not detected live nematode at 25 ℃(that was to say that nematode had been dead in the treated wood), but 5 % of the nematodes was still detected at 4 ℃. After 24 hours treatment wood with less than 22.8 % moisture could not detected live nematode, while wood with 47.3 % moisture could be found to some of nematode. The experiment confirmed dried wood with less than 22.8 % moisture,in which the nematode was not easy to survive and infect.
