建立基线生态系统信息的取样方案（例如，物种丰富度和多样性）往往没有考虑到取样技术对结果的潜在影响。对重要经济昆虫取样的研究已经证明了诱捕器颜色和诱捕器放置位置对结果的可能影响，但从自然环境中收集的数据很少。因此，我们研究了颜色（黄色和蓝色）和位置（暴露和阴影的植物）的粘性陷阱昆虫捕获和多样性估计内布拉斯加州内陆盐沼社区的影响。1996年7月，我们从67个昆虫科采集了1913个标本，在五个诱捕日期。在暴露的诱捕器上收集到更多的Cicindelidae，而在遮蔽的诱捕器上收集到更多的隐翅虫科，Dolichopodidae，Cicadellidae和Thripidae。黄色诱捕器上收集到更多的Dolichopodidae，而蓝色诱捕器上收集到更多的Syrphidae和Thripidae。香农和阿尔法多样性措施显着较高的阴影陷阱比暴露的陷阱，但不受陷阱颜色。我们的研究结果强调了在建立多样性估计时表征抽样技术的重要性。这些数据提供了第一个完整的帐户的社区水平的昆虫对彩色粘性陷阱的反应，并提供了新的信息，颜色偏好的非经济昆虫物种。
Sampling programs to establish baseline ecosystem information (e.g., species abundance and diversity) often fail to consider the potential influence of sampling techniques on results. Research on sampling economically important insects has demonstrated the possible influences of trap color and trap placement on results, but few data have been collected from natural environments. Consequently, we examined the effects of color (yellow and blue) and placement (exposed and shaded by plants) of sticky traps on insect captures and diversity estimates from a Nebraska inland salt marsh community. We identified 1913 specimens from 67 insect families collected during five trapping dates in July 1996. More Cicindelidae were collected on exposed traps, and more Staphylinidae, Dolichopodidae, Cicadellidae, and Thripidae were collected on shaded traps. More Dolichopodidae were collected on yellow traps, while more Syrphidae and Thripidae were collected on blue. Shannon and alpha diversity measures were significantly higher for shaded traps than exposed traps, but were not affected by trap color. Our results highlight the importance of characterizing sampling techniques when establishing diversity estimates. These data provide the first complete accounting of community-level insect response to colored sticky traps and provide new information for color preference of non-economic insect species.
