Aceria artemisiifoliae Vidović & Petanović (Acari: Eriophyoidea) on common ragweed - the second record in the world

Abstract

Common ragweed - Ambrosia artemisiifolia L. (Asteraceae) is an invasive plant species in Europe native to North America. Most of the records of known eriophyid mites on different ragweed species are from their native range. Our field experiments in Slovakia, 2016-2023, aimed to identify specific species feeding on common ragweed. We searched for symptomatic plants and collected growing tips, which were then preserved in 70% ethanol for further study. A recently described species of eriophyid mite, Aceria artemisiifoliae Vidović & Petanović (Acari: Eriophyoidea), was found in western and eastern Slovakia. This is the first record of the species in Slovakia and the second record in the world. It remains unclear whether this species is invasive like Ambrosia, and whether it could be used as a potential biological control agent.
