The first population of the small brown planthopper Laodelphax striatellus (Homoptera: Delphacidae) in the Netherlands

摘要

The small brown planthopper Laodelphax striatellus has always been considered a migrant species in the Netherlands, since no established populations were known. However, the first reproducing Dutch population was discovered in 2016. Climate change might have caused an area extension of L. striatellus. Future research has to show whether the area extension is permanent. Unfortunately, the habitat of the discovered population is destroyed. The small brown planthopper is of economic importance in southern Europe, mainly due to transmission of the maize rough dwarf virus (MRDV). In this respect, attention should be given to possible area extensions of this species.
