小蜂科是双翅目昆虫中最特殊的科之一，也是非膜翅目寄生蜂中最大的类群。对它们在大多数生态系统中的多样性、分布模式和季节变化知之甚少。本文报道了在中国北部百花山自然保护区73周多的时间里，用捕鼠器采集的寄生蝇类，并调查了当地物种丰富度的变化规律及其时间分布。物种最丰富的季节是夏季，但大部分标本是在春季恢复的。共采集寄生动物标本755号，隶属于85属144种，占中国北部记录种的26.5%和属的49.7%。总的物种丰富度估计为243种，这表明在该地点只采集到一小部分寄生蝇类群落，这表明北京和中国北部的寄生寄生动物的多样性可能被低估了。这项工作是利用定量采样评估中国寄生蜂多样性格局的第一步，并为理解这些具有生态意义的寄生蜂的时空多样性奠定了基础。
Tachinidae are one of the most speciose families of Diptera and the largest group of non-hymenopteran parasitoids. Little is known about their diversity, distribution patterns, and seasonal variation in most ecosystems. This study reports on tachinid flies collected by a Malaise trap over 73 weeks in Baihua Mountain Reserve, northern China, and investigates the patterns of local species richness and its temporal distribution. The most species-rich season was summer, but the majority of specimens were recovered in spring. A total of 755 tachinid specimens were collected, consisting of 144 species in 85 genera, comprising 26.5% of the species and 49.7% of the genera recorded from northern China. A total species richness of 243 was estimated, indicating that only a portion of the community of tachinid flies was collected at this location and suggesting that the diversity of tachinids might be underestimated across Beijing and northern China. This work is a first step in assessing patterns of tachinid diversity in China using quantitative sampling and establishes a baseline for comprehending the temporal and spatial diversity of these ecologically significant parasitoids.
