4. Development and genetics of mouthpart formation 4.1 Developmental biology of insect mouthparts (Dave Angelini (Colby College, USA) & Frank Smith)(serial homology of mouthpart components, embryological origin, developmental genetic patterning of Drosophila, Tribolium, Oncopeltus, development of sensory cells, Evo/devo of mouthparts in outgroup taxa, future directions)
Harald W. Krenn is an Associate Professor at the Department of Integrative Zoology at the University of Vienna (Austria), where he graduated in Zoology and Botany. His current research focuses on the evolutionary morphology of insect mouthparts, integrating new methods of functional morphology with feeding behaviour and ecology under evolutionary perspectives. He is particularly interested in interdisciplinary research on flower-visiting insects, which also involves fieldwork in the Austrian Alps, Neotropical rainforests and the Cape Floristic Region of South Africa.
