摘要: 对不同含水率的松木和杉木进行松材线虫存活率的检测实验,结果发现:(1)不同含水率的木材,在25 ℃和4 ℃下随着处理时间的延长,松材线虫的存活率不断下降;(2)含水率为12.0 %~22.8 %的木材,其中线虫存活率明显低于相同处理时间下未经烘窑烘干含水率为34.4 %~48.0 %的木材;(3)处理6 h后,含水率12.3 %的木材在25 ℃时未查到活虫(即处理木材中的松材线虫均死亡),在4 ℃时发现仍有5 %的线虫;(4)处理24 h后,经烘窑烘干含水率在22.8 %以下的木材在25 ℃和4 ℃下均未查到活虫,而在未经烘窑烘干含水率47.3 %的木材中仍然查到有47 %的存活线虫。试验初步证实含水率在22.8 %以下的木材不利于线虫的存活和侵染。

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.
