Seminario: sensory ecology and behavior

 

Invitamos a un seminario del Porfesor Jochen Zeil, el proximo viernes 9 a las 12hs en el aula Burkart.

 

El Dr. Zeil es un reconocido investigador en el área de comportamiento animal, fundamentalmente de ecológica sensorial. En sus trabajos analiza comportamientos de orientación, navegación y búsqueda en una gran variedad de especies animales vertebrados e invertebrados.

 

En esta oportunidad nos hablará de:

 

Stealthy Target Tracking in Satellite Flies

Female satellite flies (Sarcophagidae: Miltogramminae) track ground-nesting wasps (Sphecidae: Cerceris sp; back to their nests with the aim of depositing one of their larvae on the prey of the wasp, just before the wasp enters her nest. Parasitic pressure can be so high in wasp colonies that up to four satellite flies simultaneously track one wasp, sharing the airspace behind the wasp. In contrast to other examples of target tracking in insects, the aim of the flies in this task is not target capture, but the stealthy pursuit of the wasp back to her nest and a fast final approach to deposit the larva. We used normal and high-speed digital video cameras to reconstruct three-dimensional flight-paths, head and body orientation of tracking flies and their targets to identify the control variables used by the flies.
