Wild chimpanzees (Pan troglodytes) used probes made of vegetation to fish for termites (Macrotermes herus) in the Mahale Mountains of western Tanzania. Data on both the artefacts and behavior associated with their use were recorded over a 5-month period. The chimpanzees of one unit group, B Group, were seen four times to use the tools to extract the insects from their mounds. A sample of 290 tools was collected and analyzed in terms of age, seasonality, length, width, class of raw materials, species, methods of making, extent of use, and damage incurred through use. There were differences across groups in tool use in feeding on termites; some could be related to biotic factors, but others appeared to be cultural differences.
野生黑猩猩（Pan troglodytes）在坦桑尼亚西部的马哈勒山脉（Mahale Mountains）中使用植物探针来钓取白蚁（Macrotermes herus）。在 5 个月的时间里，记录了与这些工具使用相关的行为和工具本身的数据。在一个单元组 B 组中，观察到四次使用工具从蚁丘中提取昆虫。收集并分析了 290 个工具，涉及工具的年龄、季节性、长度、宽度、原材料种类、物种、制作方法、使用程度以及使用造成的损坏。在以白蚁为食的过程中，不同群体之间的工具使用存在差异；其中一些可能与生物因素有关，但其他差异似乎是文化差异。
