Hawaii is home to over 60 ant species, including five of the six most damaging invasive ants. Although there have been many surveys of ants in Hawaii, the last island-wide hand-collection survey of ants on Oahu was conducted in 1988-1994. In 2012, a timed hand-collection of ants was made at 44 sites in a systematic, roadside survey throughout Oahu. Ants were identified and species distribution in relation to elevation, precipitation and soil type was analyzed. To assess possible convenience sampling bias, 15 additional sites were sampled further from roads to compare with the samples near roads. Twenty-four species of ants were found and mapped; (F.), (Mayr), and Forel were the most frequently encountered ants. For six ant species, a logistic regression was performed with elevation, average annual precipitation, and soil order as explanatory variables. was found in areas with lower precipitation around Oahu. (Latrielle) and (Smith, F.) were found more often in lower elevations and in areas with the Mollisol soil order. Elevation, precipitation, and soil type were not significant sources of variation for Emery, and . was associated with fewer mean numbers of ants where it occurred. Ant assemblages near and far from roads did not significantly differ. Many species of ants remain established on Oahu, and recent invaders are spreading throughout the island. Mapping ant distributions contributes to continued documentation and understanding of these pests.
夏威夷是60多种蚂蚁的家园，其中包括六种最具破坏性的入侵蚂蚁中的五种。尽管此前对夏威夷的蚂蚁进行过多次调查，但上次对瓦胡岛进行的全岛手工采集蚂蚁调查是在1988年至1994年进行的。2012年，在瓦胡岛一次系统的路边调查中，在44个地点进行了定时手工采集蚂蚁的活动。对蚂蚁进行了鉴定，并分析了其与海拔、降水量和土壤类型相关的物种分布情况。为了评估可能存在的便利抽样偏差，在距离道路更远的地方又选取了15个地点进行采样，以便与道路附近的样本进行比较。共发现并绘制了24种蚂蚁的分布图；（某种蚂蚁属名，此处原文未完整给出）（法布里丘斯）、（梅尔）和（某种蚂蚁属名，此处原文未完整给出）福尔是最常见的蚂蚁。对于六种蚂蚁，以海拔、年均降水量和土壤类别作为解释变量进行了逻辑回归分析。在瓦胡岛降水量较低的地区发现了（某种蚂蚁，此处原文未完整给出）。（拉特雷尔）和（史密斯，法布里丘斯）在较低海拔地区以及有软土土壤类别的地区更为常见。海拔、降水量和土壤类型对于（某种蚂蚁属名，此处原文未完整给出）埃默里和（某种蚂蚁属名，此处原文未完整给出）来说并不是显著的变异来源。（某种蚂蚁，此处原文未完整给出）出现的地方平均蚂蚁数量较少。道路附近和远处的蚂蚁群落没有显著差异。瓦胡岛上仍有许多种类的蚂蚁，而且近期入侵的蚂蚁正在全岛扩散。绘制蚂蚁分布图有助于持续记录和了解这些害虫。
