Teaching
teaching overview
- This is an upper level course in insect development offered for the first time in Fall 2010. This course provides an in-depth treatment of the morphogenetic events of insect development, underlying mechanisms and the genetic programs controlling them. Much of its content focuses on the development of the fruit fly, Drosophila melanogaster, with particular emphasis on the establishment of the basic insect body plan, organogenesis and metamorphosis. However, because many aspects of Drosophila development are highly specialized, in cases where more ancestral processes occur in other insect taxa, these will also be addressed. The primary niche of this course in the context of the CALS curriculum is as an upper level core course in the Entomology undergraduate major. In addition, students from other majors in the Biological Sciences, such as Genetics and Development, and graduate students may find this course of interest.
