dc.description.abstract Effective pest management of the invasive swede midge (Contarinia nasturtii Kieffer) is hindered by the lack of development and mortality information in its invasive range. This thesis had 2 main objectives: 1) generate temperature-dependent development and mortality data for Ontario populations of C. nasturtii; and, 2) revise an existing C. nasturtii life cycle model (MidgEmerge) with this information. Temperature-dependent development and mortality rates were determined for all C. nasturtii life stages. This information, and robust adult count field data, were used to re-parameterize MidgEmerge and develop MidgEmergeII. Egg and larval development times were found to differ between Ontario and UK populations. The re-developed MidgEmergeII model accurately predicted C. nasturtii population dynamics in various southern Ontario locations. Results indicate that there are 3 C. nasturtii emergence phenotypes and 2-3 generations in Ontario, in contrast to the previous model. These findings have implications for C. nasturtii management in its invasive range. en_US
