Zur Ausbreitung des Rapsglanzkäfers (Meligethes aeneus F.; Col., Nitidulidae) vor der Überwinterung

The dispersal of the blossom beetle (Meligethels aeneus F.; Col., Nitidulidae) before hibernation In July 1975 about 300 000Meligethes aeneus F. imagines marked with fluorescent stain were set free at a distance of 12 km away from the beach of the Baltic Sea. Catching the insects took place with 75 yellow traps, which were exposed at 15 localities. 953 marked beetles were retrapped, of which 160 were caught next to the coast. These insects spread over a distance up to 12 km. The first ones were already caught at the coast two days after release. The mean distance per day seemed to be limited between 1–3 km.
