From a discarded heavy-equipment tire (ca. 57 liter) at an industrial construction site, we collected 655 (86.0%) Orthopodomyia signifera, 23 (3.0%) Toxorhynchites rutilus septentrionalis, 17 (2.2%) Aedes japonicus japonicus, and 67 (8.8%) Culex pipiens pipiens. Although larvae of Aedes albopictus and Aedes triseriatus were not collected from this container, both species were prevalent as host-seeking adults and readily collected as larvae from other containers at this site. Laboratory trials to test the survival of prey (Ae. albopictus, Cx. p. pipiens, or Or. signifera) in the presence of Tx. rut. septentrionalis showed that survival of prey larvae differed among species. Multiple comparisons revealed that Ae. albopictus had the lowest and Or. signifera the highest survival in the presence of Tx. rut. septentrionalis. Survival of Or. signifera and Cx. p. pipiens was not significantly different from one another, but both were different from Ae. albopictus. Further testing is warranted to test other factors responsible for differences in the interspecific relationship between Or. signifera and other species in tree hole communities.
在一个工业建筑工地的一个废弃重型设备轮胎（约57升）中，我们收集到655只（86.0%）显著按蚊、23只（3.0%）北方巨蚊、17只（2.2%）日本伊蚊和67只（8.8%）致倦库蚊。尽管未从此容器中收集到白纹伊蚊和三带喙库蚊的幼虫，但这两个物种作为寻找宿主的成虫很常见，并且很容易从此处其他容器中收集到它们的幼虫。测试北方巨蚊存在时猎物（白纹伊蚊、致倦库蚊或显著按蚊）存活率的实验室试验表明，猎物幼虫的存活率因物种而异。多重比较显示，在北方巨蚊存在的情况下，白纹伊蚊的存活率最低，显著按蚊的存活率最高。显著按蚊和致倦库蚊的存活率彼此之间没有显著差异，但两者都与白纹伊蚊不同。有必要进行进一步测试，以检验导致显著按蚊与树洞群落中其他物种种间关系差异的其他因素。
