Creator:: Hoffman, George D.
Abstract:: While current theories describing the insect-plant interaction have emphasized the biochemical aspects of the relationship, morphological components can also play a significant role in determining which plants or tissues are susceptible to insect attack. Xylem sap on which spittlebugs feed may lack many of the plant compounds responsible for host...

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:: 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:: 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...
