摘要:Mass occurrence of the grasshopper Miramella cf.
alpine (Kollar, 1833) (Acridiade: Catantopinae) was
detected in summer 2009 in about 500 ha of mixed forest
with a high share of secondary larch stands in the
Burgenland. The areas with defoliated larch were
especially affected. Adult grasshoppers were feeding
not only on ground vegetation (eg. blueberry) but also
on the needles of fresh cut larch trees and young
standing trees of Larix decidua. With the exception of
the gall midge Dasineura laricis no other causes for
defoliation could be found. Evidence suggests an association
between damages on larch and grasshoppers.
