Abstract: Dr. Bill Walton was a remarkably effective and dedicated teacher. He taught several undergraduate classes, though he was particularly fond of teaching Insect Ecology, Introductory Ecology and Evolution , and Aquatic Insects. The student loved these classes, earning Bill top ratings in every course he taught. Bill was specifically recognized for his exceptional teaching prowess through several very prestigious teaching awards. These included being a National Academies Education Fellow in the Life Sciences (2013) and receiving the Outstanding Teaching Award on the UCR campus (2017), from USDA-NIFA (2018,) and from the Entomological Society of America (2018). In addition, the UCR Entomology graduate students awarded him the Faculty Mentor Award in 2010, in recognition of his dedication to mentoring and instruction of our students. Bill’s service to entomology and vector ecology is truly remarkable. In particular, Bill served as President of the American Mosquito Control Association and was also a member and Chair of the Editorial Board for the Journal of the American Mosquito Control Association. His service activities are too numerous to include in this abstract but will be reviewed in greater detail during the presentation.
