Parasitoids and pathogens in a collapsing Lymantria dispar (Lepidoptera: Erebidae) population in Lower Austria: Raw data

A local population outbreak of the spongy moth, Lymantria dispar L. (Lepidoptera: Erebidae), in Lower Austria resulted in the defoliation of an oak forest in 2018 and 2019. In the study year 2020, the population density was still high but was expected to decline. In the present work, the role of parasitoids and pathogens in the collapse of the population was investigated. The dataset contains the raw data of the investigation.2018至2019年，奥地利下奥地利州发生当地舞毒蛾（spongy moth，学名*Lymantria dispar* L.，鳞翅目Lepidoptera 裳蛾科Erebidae）种群暴发事件，致使一处栎林遭受严重失叶。在本研究的观测年份2020年，该种群密度仍处于较高水平，但预计将出现下降趋势。本研究针对寄生性天敌与病原物在该种群崩溃过程中的作用开展了调查，本数据集包含本次调查的原始数据。
