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 (<em>Araneae</em>), dragonfly (<em>Anisoptera</em>), beetles (<em>Coleoptera</em>), housefly (<em>Musca Domestica</em>), crickets (<em>Gryllidae</em>) and moths (<em>Lepidoptera</em>). 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）斯通池塘（Stong Pond）开展，实验时段为东部时间（ET）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。本研究共布设18个盛有肥皂水的诱捕碗，其中9个放置于草地生境，剩余9个放置于林地生境。使用测距卷尺（distance measuring tape）定位，各诱捕碗间距均为3米，且在两种生境中均放置约1小时。诱捕碗采用蓝色、白色与黄色三种配色，用于在两种生境中吸引不同类群的昆虫。从肥皂水诱捕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*）。根据采集的数据，相较于仅分布树木与少量草本植物的林地，草地生境因植被繁茂且伴有花卉分布，所捕获的昆虫数量更多。来自第2组的实验搭档莎拉·阿尔萨马拉伊（Sarah Alsammarraie）与沙龙·达米（Sharon Dhami）协助搭建了盘式诱捕器（pan trap）。
