The number of insect species and insect abundances decreased severely
during the past decades over major parts of Central Europe. Previous
studies documented declines of species richness, abundances, shifts in
species composition, and decreasing biomass of flying insects. In this
study we present a standardized approach to quantitatively and
qualitatively assess insect diversity, biomass and the abundance of taxa,
in parallel. We applied two methods: Malaise traps, and automated and
active light trapping. Sampling was conducted from April till October 2018
in southern Germany, at four sites representing conventional and organic
farming. Bulk samples obtained from Malaise traps were further analyzed
using DNA metabarcoding. Larger moths (Macroheterocera) collected with
light trapping was further classified according their degree of
endangerment. Our methods provide valuable quantitative and qualitative
data. Our results indicate more biomass and higher species richness, as
well as twice the number of Red List lepidopterans in organic farmland
than in conventional farmland. This combination of sampling methods with
subsequent DNA metabarcoding and assignments of individuals according
depending on ecological characteristics and the degree of endangerment
allows to evaluate the status of landscapes, and represents a suitable
set-up for large-scale long-term insect monitoring across Central Europe,
and elsewhere.
