衡水市是传统农业大市，是华北平原的粮仓和京津冀重要的绿色优质农产品生产供应基地。探究本地瓢虫等天敌资源及其发生情况对开展和促进农业害虫的生物防治具有重要意义。文章数据采集地点为河北省农林科学院旱作农业研究所（衡水市农业科学研究院）护驾迟试验站内，站内动植物资源、生物多样性水平高，瓢虫等天敌资源丰富。本论文集包含了2018—2020年试验站内瓢虫等天敌资源及种群动态数据、马来氏网昆虫收集相关情况等，同时还记录了调查地点的环境、生态、气候等数据，其中天敌资源、种群动态和马来氏网数据共312条，照片918张，标本瓶51瓶，气象数据1408条。本数据集为明确衡水地区天敌的资源家底、分析发生与种群动态、比较气候变化等因素对天敌的影响提供数据基础。

Hengshui is a traditional agricultural city, and also the granary of the North China Plain, an important base that supplies high-quality green agricultural products to Beijing, Tianjin and Hebei. To promote local biological control of agricultural pests, it is important to survey natural enemy resources such as coccinellid beetles and to investigate their occurrence. Data presented herein were collected from 2018 to 2020 in HUJIACHI Experimental station, Dryland Farming Institute, Hebei Academy of Agricultural and Forestry Sciences (Hengshui Academy of Sciences), the plant and animal resources and biodiversity of the observatory are high, and the natural enemy resources such as ladybug are abundant. The dataset includes resources of local natural enemies, especially coccinellid beetles, their population dynamic data, and information about malaise trap insect collections. It also includes environmental, ecological, and climatic data of the survey site. The dataset concludes 312 data of natural enemy resource, population dynamic, malaise trap, 918 pictures, 51 malaise trap collecting bottles and 1408 climatic records. This dataset provided basic information about natural enemy resources in Hengshui, which allows future analyzing of natural enemy occurrence and population dynamics, and investigating impact of climate change and other factors on natural enemies.
