2018-2022年杨凌地区天敌瓢虫、食蚜蝇数据集

A dataset of Coccinellidae and Syrphidae in Yangling from 2018 to 2022

农业在杨凌地区具有重要的战略地位,在农作物栽培管理中,合理利用天敌昆虫可以降低农药使用频率,减轻农药残留危害。捕食性瓢虫和食蚜蝇是杨凌田间常见的两类天敌昆虫,能够捕食蚜虫在内的多种害虫。以往,缺乏对杨凌农田生态系统中瓢虫和食蚜蝇类天敌昆虫的系统监测。为明确杨凌地区瓢虫和食蚜蝇资源现状,本研究利用马来氏网和人工调查等方法,收集了2018至2022年该地区瓢虫和食蚜蝇类天敌昆虫资源数据。最终采集捕食性瓢虫标本914头,食蚜蝇标本1440头。其中瓢虫22种,有16种鉴定到种,6种鉴定到属;食蚜蝇14种,12种鉴定到种,2种鉴定到属。天敌昆虫筛检及鉴定均由专业人员完成,保证了数据质量。本数据集提供了天敌瓢虫和食蚜蝇种类、数量以及发生动态等基本数据,同时提供了大量相关物种的标本照片、生态照片以及马来氏网照片、标本瓶照片和附近环境照片,为后续保护利用天敌昆虫提供重要依据。

Agriculture holds a significant strategic position in Yangling.In crop cultivation management,the strategic use of insect natural enemies can effectively reduce the reliance on pesticides and mitigate the potential harm caused by pesticide residues.Among these natural enemies,Coccinellidae and Syrphidae are the most prevalent and valuable guilds preying on many pests including aphids,in the field.However,there was limited knowledge of the species and occurrence of Coccinellidae and Syrphidae due to a lack of systematic monitoring in Yangling farmland.In order to clarify the resources of Coccinellids and Syrphids in Yangling,we monitored these two groups using both Malaise traps and regular surveys in farmland in Yangling,Shaanxi Province from 2018 to 2022.In the past five years,a total of 914 predatory Coccinellids and 1440 Syrphids have been collected.Among Coccinellids,22 species of Coccinellids were identified,with 16 species and 6 genera.Additionally,there were 14 species of Syrphids,with 12 species and 2 genera identified.The screening and identification of natural enemy insects were conducted by professionals to ensure data quality.This dataset provides basic data on the species,quantity,and occurrence dynamics of predatory Coccinellids and Syrphids.Moreover,it also offers a large number of natural enemy insect specimen photos,ecological photos,Malaise trap photos,specimen bottle photos,and photos of the surrounding environment.It can serve as valuable references for future endeavors aimed at the protection and utilization of predatory insects.
