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...

Full Text:: Biological Control: A Case Study of the Cinnabar Moth Tyriajacobaeae Abstract approved: The cinnabar moth

Creator:: Cox, Caroline Shipley
Abstract:: To assess the effect of summer moisture stress on the capacity of tansy ragwort (Senecio jacobaea L.) to compensate for defoliation by the cinnabar moth (Tyria jacobaeae LT7), the performance of plants grown under different irrigation regimes was measured. The proportion of plants producing new leaves following defoliation, the number...
