Pantrap field experiment

10 Pantraps of yellow, blue and white were placed in a linear line of alternating colours, filled half way with soapy water in both the grass field as well as the wood lot. They remained there for approximately 2.5 hours, and then the insects in the bowls were recorded.将10个黄、蓝、白三色的盆式诱捕器（Pantraps）以颜色交替的线性排布方式放置，在草地与林地两个区域中，各盆均注入半量肥皂水。将其静置约2.5小时后，对各盆内的昆虫进行了记录。
