| Abstract |
Ein Kupferstecherweibchen findet, angelockt durch die pheromonhaltigen Bohrmehlkrümel, das Bohrloch eines Männchens und kriecht hinein. Sechs Weibchen nagen je einen Muttergang, die schlüpfenden Larven fressen senkrecht zum Muttergang verlaufende Larvengänge. Es folgen Verpuppung und Schlüpfen der Jungkäfer. (Zeitraffung). Die Jungkäfer nagen ein Loch durch die Rinde nach außen und fliegen ab. A female six-toothed spruce bark-beetle, attracted by the bore meal crumbs (frass) containing pheromones, finds a male's borehole and crawls into it. Six females each gnaw a central gallery, the hatched larvae chew larval galleries perpendicular to the central gallery. Pupation and emergence of the young beetles follow. (Time-lapse photography). The juvenile beetles gnaw a hole outwards through the bark and fly away. |
