Rund 2000 Beeren sammelten sie aus verschiedenen Regionen Deutschlands, untersuchten sie auf Einstichspuren und schnitten die Beeren auf, um den Befall durch die Larve der Sauerdorn-Bohrfliege ( Rhagoletis meigenii ) zu untersuchen.
Dieser Parasit sticht die Beeren an, um seine Eier darin abzulegen.
Wenn die Larve es schafft, sich zu entwickeln, frisst sie oft alle Samen in der Beere auf.
www.uni-goettingen.deApproximately 2000 berries were collected from different regions of Germany, examined for signs of piercing and then cut open to examine any infestation by the larvae of the tephritid fruit fly ( Rhagoletis meigenii ).
This parasite punctures the berries in order to lay its eggs inside them.
If the larva is able to develop, it will often feed on all of the seeds in the berry.
