Creator:: Lunde, A. Katarina
Abstract:: Classic biological control can be a powerful option for those tasked with managing biological invasions; however, some biocontrol releases lead to non-target attack – feeding, damage or development on species other than the target species. The cinnabar moth, Tyria jacobaeae L. (Lepidoptera: Erebidae) was introduced to Western Oregon as a...

Creator:: Rodman, Madison G.
Abstract:: Non-target effects are one of the greatest potential risks of weed biological control programs, and understanding non-target effects of biological control at the population level is crucial for predicting when they will occur and altering the perception of biological control as a whole. In this thesis, we assessed the ecological...

Creator:: Fuller, Jason L.
Abstract:: The cinnabar moth, Tyria jacobaeae (L.) (Lepidoptera:Arctiidae), was released in 1959 to control the grassland weed tansy ragwort, Senecio jacobaea L. (Asteraceae), despite evidence that caterpillars of this species can feed on native plants within the genera Senecio and Packera. Previous studies confirmed the moth's ability to develop on the...

Creator:: Schat, Marjolein
Abstract:: Purple loosestrife is a wetland perennial that came to the eastern seaboard of North America in ship ballast and raw wool in the 1800's. Since coming to the United States, it has spread across the country, forming dense monospecific stands in wetlands. Mechanical and chemical control was expensive and ineffective,...

Creator:: Schooler, Shon
Abstract:: Invasive plants have the potential to reduce the diversity of species in plant and animal communities. I examined the negative effect of two invasive wetland plants, purple loosestrife and reed canary grass, on the species richness and diversity of plant and moth communities within 24 wetland study sites in the...

Creator:: Campanella, Donald M.
Abstract:: A study consisting of three parts was undertaken to investigate how variation in species interactions, population genetic structure, epidemiological parameters, and plant breeding system may influence the ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae). Interactions between natural enemy species may modify their net effect on...

Creator:: Karacetin, Evrim
Abstract:: The cinnabar moth (Tyria jacobaeae (L.), Lepidoptera: Arctiidae) is an icon in population ecology and biological control that has recently lost its shine based on evidence that (1) it is less effective than alternatives (such as the ragwort flea beetle Longitarsus jacobaeae (Waterhouse) (Coleoptera: Chrysomelidae) for controlling ragwort Senecio jacobaea...
