Wirksamkeit der Erzwespe Lariophagus distinguendus (Förster) (Hymenoptera: Pteromalidae) bei der biologischen Bekämpfung des Kornkäfers Sitophilus granarius (L.) (Coleoptera: Curculionidae) in Lagergetreide
[Effectiveness of the chalcid wasp Lariophagus distinguendus (Förster) (Hymenoptera: Pteromalidae) for biological control of the granary weevil Sitophilus granarius (L.) (Coleoptera: Curculionidae) in stored grain]
Mitteilungen der deutschen Gesellschaft für allgemeine und angewandte Entomologie 13, 197-200
Abstract: Reproductive capacity and longevity of Lariophagus distinguendus (Förster) (Pteromalidae) was examined in the laboratory under different conditions with larvae of the granary weevil Sitophilus granarius (L.) (Curculionidae) as hosts. Reproductive capacity varied largely between L. distinguendus strains of different origin. Longevity was increased in the presence of hosts, probably due to host feeding by the parasitoids. Within the range of 15°C to 21°C, different temperatures had no impact on longevity of female parasitoids. The results were discussed with respect to the potential use of L. distinguendus for the biological control of the granary weevil.
