摘要
采用以云杉八齿小蠹Ips typographus L.侵入云杉皮下为起点,至下一代成虫羽化外出为止的统计方法对其进行发育起点温度和有效积温的测定。结果表明,云杉八齿小蠹此段的发育起点温度为(18.3±0.2)℃,有效积温为(195.4±10)日.度。
The effective accumulated temperature and threshold temperature of bark beetle, lps typographus, were determined from adult boring through the bark to the new first adult emergence. The effective accumulated temperature was （ 195.4 ± 10） degree-day, and the threshold temperature was （ 18.3 ± 0.2） ℃.
