我们主要研究了日本寒温带天然森林中乙醇诱饵诱捕的头节类和颈足类的群落结构和季节种群趋势。在乙醇诱捕器捕获的个体中，Xyleborini部落的头节类物种占到了70%以上，尽管该研究区域可能有大量的颈足类物种。这些结果表明，Xyleborini部落的头节类物种对乙醇诱饵诱捕的敏感性可能较高，乙醇诱饵诱捕方法可以针对有限数量的头节类和颈足类物种。因此，单纯基于乙醇诱捕法的分析可能会导致对头节类和颈足类物种群落结构的误解。使用广义线性模型(GLM)对头节类和颈足类种类数量的季节变化进行分析表明，乙醇诱饵诱捕器在春季似乎比其他季节更有效地发挥作用。因此，在分析以乙醇为诱饵的诱捕普查所获得的数据时，应考虑诱捕季节，特别是对于头节类和颈足类物种。
We mainly examined the community structure and seasonal population trends of scolytid and platypodid species captured via ethanol-baited traps in a natural cool-temperate forest in Japan. The scolytid species in the tribe Xyleborini represented more than 70 % of individuals captured in ethanol-baited traps, although the platypodid species could be abundant in this study area. These results indicate that the scolytid species in tribe Xyleborini might have higher sensitivity to ethanol-baited traps than others and the ethanol-baited trapping method could target the limited number of scolytid and platypodid species. Therefore, analysis based only on the ethanol-baited trapping method may lead to misunderstanding the community structure of scolytid and platypodid species. The analysis of the seasonal changes in number of scolytid and platypodid species, using a generalized linear model (GLM) showed that the ethanol-baited traps appeared to function more effectively in spring than in other seasons. Hence, the trapping season should be considered when analyzing the data obtained from ethanol-baited trapping census, especially with scolytid and platypodid species.
