Pan trap experiment in Grassland and Woodlot areas indicating insect pollinators' preference between red, orange and yellow flowers

In order to investigate the attraction of pollinators to the color range of yellow, orange and red an experiment was designed using 60 pan traps. Ten of each colour pantraps were laid out alternating in colour from yellow, orange, and red. This was done in both grassland and woodland region, 30 in each area. The pan traps remained in the areas for a total of three hours. The time was recorded for when the pan traps were finished being laid out and the time the experimenters began collecting data. Also data was recorded reporting the colour, the number of total insects in each pan trap, the taxonomic name of the insects, and number of insects in each taxomonic group. The results were used to observe the correlation between abundance insect pollinators and possible varying degrees of attraction to yellow, red and orange flowers. Furthermore comparing the effect of location (of woodland and grassland regions) on the abundance of insect taxonomic groups present as well as the effect of location on any possible trend indicating a colour preference of pollinators.

为探究传粉昆虫对黄色、橙色与红色色域的趋性，本研究设计了一项使用60个色盘诱捕器（pan traps）的实验。实验中每种颜色的诱捕器各设10个，按黄、橙、红的顺序交替布设。实验分别在草原与林地两种生境中开展，每个区域布设30个诱捕器。色盘诱捕器在实验区域内放置总计3小时，记录诱捕器布设完成时刻与实验人员开始数据采集的时刻。同时记录的数据还包括：每个色盘诱捕器的颜色、其中昆虫的总数量、昆虫的分类学名，以及各分类类群的昆虫数量。本研究结果用于分析昆虫传粉类群的丰度与对黄、红、橙色花朵的不同吸引程度之间的相关性。此外还对比了生境（草原与林地）对昆虫分类类群丰度的影响，以及生境对传粉昆虫颜色偏好相关趋势的潜在影响。
