Invasive weeds are one of the worst scourges within rangelands, and it is often dif cult to control them using conventional approaches such as herbicides or mowing. But all is not lost—insect allies can help us combat these noxious plants! We are talking about insect biocontrol agents, or plant-eating bugs that feed on weeds. However, there are hurdles these insects must overcome to successfully control weed populations; the rst is establishing a viable population after being released. In this article we fo- cus on one such ecological drama, which is the biocontrol of Canada thistle in North Dakota with a stem-mining weevil. DOI: 10.2458/azu_rangelands_v34i5_prischmann-voldseth

Society for Range Management

Rangelands, a publication of the Society for Range Management, serves as a forum for the presentation and discussion of facts, ideas, and philosophies pertaining to the study, management, and use of rangelands. The journal features scientific and historical articles as well as Society news. It provides readers with scientifically accurate information in a user-friendly format, placed in context of the world we live in today. Rangelands is a practical (non-technical) counterpart of Rangeland Ecology & Management (formerly the Journal of Range Management). The Global Rangelands collection includes articles from Rangelands up to 3 years from the current year. Access to more recent content is available by subscription from BioOne and the Society for Range Management and may also be available at your local university library.
