The spatial patterns of field arthropod communities are an essential part of ecology and can provide fundamental data regarding field ecological processes and reveal the mechanism of ecosystem biodiversity maintenance. This study investigated the spatial distribution pattern of field insect communities to detect the spatial relationships between insect communities in farmland. The study site was located at the Dehui Agro-ecological Experimental Station of Black Soil, Jilin, China. Insect communities and environmental factors were sampled at 121 uniformly distributed points in a 400 × 400 m plot in August, September, and October 2015. The analysis revealed that insect communities from June to October demonstrated significant spatial correlation, and 6085 samples of 47 species and 47 families in 11 orders were collected from the insect community in the farmland. The farmland insect community structure changes and dynamic changes of nutritional function groups occur with time. According to the 400 x 400 m plot, the diversity of farmland insect communities and functional groups is maintained at a relatively high and stable level. In this study, a total of 6085 samples of corn farmland insects were obtained using the fluke method and direct observation method, including 11 orders, 26 families and 47 species, 4 absolute dominant populations, 6 main dominant populations, and 37 other populations. These studies can provide help for pest control in the spring corn area of Northeast China.
农田节肢动物群落的空间格局是生态学的重要组成部分，可为农田生态过程提供基础数据，并揭示生态系统生物多样性维持的机制。本研究调查了农田昆虫群落的空间分布格局，以探测农田中昆虫群落之间的空间关系。研究地点位于中国吉林黑土农业生态实验站。2015 年 8 月、9 月和 10 月，在一个 400×400 m 的样地内的 121 个均匀分布点上采集了昆虫群落和环境因子样本。分析表明，6 月至 10 月的昆虫群落具有显著的空间相关性，共采集到 47 科 47 种 6085 个样本，隶属于 11 个目。农田昆虫群落结构变化和营养功能组的动态变化随时间而发生。根据 400×400 m 的样地，农田昆虫群落和功能组的多样性保持在相对较高且稳定的水平。本研究采用吸虫法和直接观察法共获得 6085 份玉米农田昆虫样本，包括 11 个目、26 个科和 47 个种，其中有 4 个绝对优势种群、6 个主要优势种群和 37 个其他种群。这些研究可以为中国东北地区春玉米区的害虫防治提供帮助。
