Projekt description
For decades natural antagonists of bark beetles have been considered to have a high regulatory potential. With regard to the regulation of the spruce bark beetle (Ips typographus L.), parasitoids hold a special position due to their strong host specialization. Especially species from the Hymenoptera order cause promising parasitization rates and have both good mobility and a high reproduction rate. Parasitoid hymenopterans also indicate a good prerequisite for biological control of pests due to their prospective potential for artificial mass rearing.
The EIVES project aims to enable a high potential of these antagonists at the first appearance of the spruce bark beetle. The first step of the project is to identify target species frequently occurring in the region of the Tharandt Forest, which, in addition to a verifiable density reduction of Ips typographus, also offer opportunities for uncomplicated and practical artificial rearing. Experiments will be conducted to establish a suitable rearing technique for these species that will provide the basis for the subsequent artificial rearing. Thresholds for the regulatory potential of the antagonists will be derived by experiments under controlled conditions in both laboratory and ecological trials. Controlled field trials on woodpiles will be conducted to obtain initial results on the application of the reared antagonists. The project also includes the identification of additional bark beetle species for which the target species could be used.
