84 pp. / First Edition Published 2001 / The noxious weed problem in the western United States has been described as, a biological forest fire racing beyond control because no one wants to be fire boss. Indeed, when small weed infestations are left unchecked, they can grow exponentially and spread across the land much like a slow-moving biological wildfire. However, land consumed by fire usually recovers and is often more productive than before the fire occurred. On the other hand, land consumed by noxious weeds may be irreversibly changed and never again reach its full biological potential. Reviewed 12/2016, First Edition Published 2001

Canada thistle is a clone forming perennial weed that spreads aggressively and is difficult to control. One approach to managing invasive weeds is integrating numerous tactics instead of relying on a single tactic. Therefore, the objectives of this research were: 1) assess impacts of Hadroplontus litura, common sunflower competition, and soil nutrients on Canada thistle, and 2) investigate head capsule morphometrics and model H. litura developmental timing. Common sunflower competition, low soil nutrients, and H. litura herbivory negatively impacted aspects of Canada thistle growth and reproduction, but effects varied. Additionally, H. litura effects on thistle morphology were mild whereas the effects of soil nutrition and competition were persistent throughout the experiment. Histogram analysis and verification via Dyar’s rule produced adequate larvae categorization by instar number. Logistic thermal time models developed to predict mean developmental time were most accurate for first instar larvae and least accurate for egg stage.
