Abundance and Diversity of Insects using Pan Trap at Stong Pond

The experiment took place at York University, Stong Pond on September 28, 2015, between 3:00-4:30pm (ET). The temperatures were 19˚C, cloudy and humid, however, prior to the study rain had occurred. In the study, 18 bowls were filled with soapy water, 9 were placed in the grassland and 9 were placed in the woodlot. Using the distance measuring tape, the bowls were each 3m apart from the previous placed bowl and they were left in each habitat for approximately 1 hour. The colours of the bowls were blue, white and yellow which were used to attract different sets of insects in both habitats. Common insects found in the soapy bowls were spiders (Araneae), dragonfly (Anisoptera), beetles (Coleoptera), housefly (Musca Domestica), crickets (Gryllidae) and moths (Lepidoptera). According to the data collected, most insects were found in grassland due to the rich vegetation and the flowers, than the woodlot which had only trees and some grass. Sarah Alsammarraie and Sharon Dhami, lab partners from Group 2, helped to set up the pan trap.

本实验于2015年9月28日在约克大学（York University）思塘（Stong Pond）开展，时段为美国东部时间下午3:00至4:30。当日气温19℃，天气多云且潮湿，实验开始前曾有降雨。本次实验共设置18个盛有肥皂水的诱集碗，其中9个安置于草地生境，剩余9个安置于林地生境。所有诱集碗均使用测距卷尺定位，相邻碗具间距为3米，且在各生境中放置时长约1小时。诱集碗采用蓝、白、黄三色，用于在两类生境中吸引不同类群的昆虫。在肥皂水诱集碗中采集到的常见昆虫包括蜘蛛（Araneae）、蜻蜓（Anisoptera）、甲虫（Coleoptera）、家蝇（Musca Domestica）、蟋蟀（Gryllidae）以及蛾类（Lepidoptera）。据采集的数据显示，因草地生境植被繁茂且伴生花卉，其捕获的昆虫数量多于仅分布树木与少量草本的林地生境。来自第2组的实验搭档莎拉·阿尔萨马拉伊（Sarah Alsammarraie）与莎伦·达米（Sharon Dhami）协助搭建了盘诱捕器（pan trap）。
