In this study the coccinellid fauna (Coleoptera, Coccinellidae) on
Nordmann fir (Abies nordmanniana) Christmas Tree plantations was
compared with those in spruce regeneration (Picea abies) and maize
fields (Zea mays) in Bavaria during the vegetation period of the year
2015. Malaise traps were set up and emptied every 2 weeks (8
repetitions). All in all, there were 1191 individuals and 26 species.
476 individuals were found in maize fields, 416 individuals in spruce
regenerations and 299 individuals on Christmas tree plantations. There
were 13 species in maize fields, 20 species in spruce regenerations and
19 species in Christmas Tree Plantations. The abundance of the most
frequently species Harmonia axyridis (PALLAs 1773) was significantly
higher in maize fields than in the other two habitats. Non-metric
multidimensional scaling showed almost similar coccinellid communities
in maize fields, moderate distribution on Christmas Tree Plantations but
with no overlap in maize fields and wide dispersion for coccinellid
communities in spruce regenerations with large overlaps. Habitat
structure and prey are discussed as possible parameters for differences
in the composition of coccinellid communities.
