title: Microhymenoptera in roadside verges and the potential of arthropod-friendly mowing for their preservation

description: This dataset contains data from the paper: “Haas-Renninger, M., Weber, J.,
 Felske, I., Kimmich, T., Csader, M., Betz, O., Krogmann, L., Steidle, J.
 L.M. 2023. Parasitoid Hymenoptera in roadside verges and the
 potential of insect-friendly mowing for their
 preservation. Journal of Applied Entomology.” The study
 investigates which families of parasitoid Hymenoptera occur in roadside
 grassland and might suffer from mowing with a conventional mowing head
 ("MK1200" from MULAG), which parasitoid families
 benefit from insect-friendly mowing using an “insect-friendly” mowing head
 ("Eco 1200 plus" from MULAG), and which parasitoid
 families benefit from the use of a flushing bar attached to the mowing
 head. We found specimens of 18 families from the six parasitoid
 superfamilies Chalcidoidea, Ceraphronoidea, Diaprioidea, Ichneumonoidea,
 Platygastroidea, and Proctotrupoidea. Mowing with a conventional mulching
 mower caused a significant loss of up to 64 % for parasitoid Hymenoptera.
 The Eco 1200 plus showed an insect-friendly effect only on the number of
 individuals of Chalcidoidea, saving 38 % of individuals compared to the
 conventional mower. The flushing bar showed a significant effect on total
 number of individuals with a reduction only on Chalcidoidea and a tendency
 for Ichneumonoidea with 30 % and 47 %, respectively. This study shows that
 mowing with a conventional mulching mower has detrimental effects on
 parasitoid Hymenoptera and that this effect can be partly reversed through
 the insect-friendly mower and a flushing bar.
description: For the first experiment, Hymenoptera samples from "Steidle, J. L.M., Kimmich, T.,
 Csader, M. Betz, O. 2022. Negative impact of roadside mowing on arthropod
 fauna and its reduction with “arthropod-friendly” mowing technique.
 <em>Journal of Applied Entomology</em>"<em>
 </em>were reanalyzed. Here,
 plots were either not
 mown, or mown with the a standard mowing head "MK1200", or the
 mowing head "Eco 1200 plus" (both from the company MULAG,
 Germany). In the second experiment, plots were either
 not treated or treated with a flushing bar without mowing head.
 In both experiments, Arthropods were sampled in the plots using
 biocoenometers and an insect vacuum cleaner, and Hymenoptera were
 determinded up to family level.
