Predatory Behaviour of Larval Alluaudomyia formosana Okada on Alluaudomyia xanthocoma Kieffer (Diptera: Ceratopogonidae)–Video Documentation
- 39 Downloads
The predation of adult Alluaudomyia upon several insects is well documented. However, the phenomenon of larval predation within the group is scant. The videos depict the predatory behaviour of larvae of Alluaudomyia formosana on Alluaudomyia xanthocoma within a petridish in the laboratory. The footages clearly demonstrate the mode of infliction of A. formosana on the intertergal membrane of A. xanthocoma with concomitant extradition of tissue fluids which led to death of the larvae.
