Early male production in a subtropical paper waspRopalidia fasciata (Hymenoptera: Vespidae)

  • Y. Itô
  • Sk. Yamane


In Okinawa,Ropalidia fasciata males emerge at all stages of the colony cycle and they can inseminate first brood females. These first brood females can found their own nests, lay female-destined eggs on these, or work for their natal colonies. This flexible reproductive strategy ofR. fasciata is considered to be adaptive under environmental conditions where most of colonies are destroyed by typhoons, ant predation and parasitism.

Die frühzeitige Männchenproduktion bei einer subtropischen Faltenwespe,Ropalidia fasciata, unter besonderer Berücksichtigung der Erstbrutweibchen


BeiRopalidia fasciata auf Okinawa entstehen die adulten Männchen während des gesamten Koloniezyklus. Die frühzeitig entstehenden Männchen können sich mit den Erstbrutweibchen paaren. Diese Erstbrutweibchen können sowohl selbst Kolonien gründen als auch weibchendeterminierte Eier in ihre mütterlichen Nester legen oder für ihre Kolonien arbeiten. Diese flexible Strategie vonRopalidia fasciata wird als Anpassung an eine Umwelt interpretiert, in der die meisten Nester durch Taifune, räuberische Ameisen und parasitische Wespen zerstört werden.
