短通信等，2005年)。然而，这两个发现是基于对少量甲虫的调查。在本研究中，我使用足够数量的甲虫进行统计分析，考察了互交密蝽蛹室的位置和甲虫出蛹的单株树对甲虫携带线虫数量的影响。2001年3月15日，在日本茨城县霞aura市林业和林产品研究所千代田实验站，将前一年因枯萎病而死亡的7棵20至30岁的日本红松（Pinus densiflora）砍伐成1米长的圆木。这些1米长的原木被放置在日本茨城县筑波市FFPRI的一个屏风笼子里。在2001年5月28日至29日期间，这些原木被切成316段，长25厘米，直径2.2至24.8厘米，然后纵向放入直径25厘米× 28厘米深的塑料容器中，每个容器内装一至两根原木。这些容器被放置在相同的筛笼中，每个容器上都覆盖着钢网。试验期间每周浇几次水，2001年6 - 7月每天进行观察。
Short communication et al., 2005). However, these two findings were based on an investigation with a small number of beetles. In the present study, I examined the effects of location of M. alternatus pupal chambers and individual trees from which beetles emerged on the number of nematodes carried by the beetles using an adequate number of beetles for statistical analyses.Seven 20-to 30-year-old Japanese red pine (Pinus densiflora) trees, killed by wilt during the previous year, were felled and cut into 1-m-long logs at Chiyoda Experimental Station of Forestry and Forest Products Research Institute (FFPRI), Kasumigaura City, Ibaraki Prefecture, Japan, on 15 March 2001. The 1-m-long logs were placed in a screen cage at FFPRI, Tsukuba City, Ibaraki Prefecture, Japan. From 28-29 May 2001 the logs were cut into 316 pieces, 25 cm long and 2.2-24.8 cm diam. then placed lengthwise in 25 cm diam.× 28 cm deep plastic containers, with one or two logs in each container. The containers were placed in the same screen cage and each was covered with a steel mesh net. The logs were watered several times a week during the experiment and were observed daily from June to July 2001.
