4.  OPERATIONS COMPONENT CONTRIBUTIONS TO TEAM LEAFY SPURGE, AREA WIDE INTEGRATED MANAGEMENT OF LEAFY SPURGE (EUPHORBIA ESULA)

Robert D. Richard1, Chad W. Prosser2, and Connie O’Brien3

Abstract: USDA, APHIS and USDA, ARS teamed together to organize, manage, and implement a biologically-based Integrated Pest Management (IPM) project, focused along 300 miles of the Little Missouri River in Wyoming, Montana, North Dakota, and South Dakota. The Ecological Area-Wide Management of Leafy Spurge (TEAM LS) began in 1997. The goal of the project was to develop and demonstrate ecologically-based IPM strategies that could be used to achieve affordable, effective self-sustainable leafy spurge control. Successes in establishment and collection allowed for over 15,600 releases of Aphthona spp. throughout the Little Missouri drainage and other leafy spurge infested states and Canadian provinces. Through TEAM Leafy Spurge Operations, 47,763,000 insects have been provided to a total of 82 counties in 12 states and 3 Canadian provinces. Within the "TEAM" Program, biological control methodologies were designed as a control foundation, to be used alone or as a base strategy, coupled with other control methods, such as multi-species grazing and herbicides. Specific contributions of Operations include development of large volume insect collection, sorting, packaging for transport, and delivery of biological control insects. Nearly 48 million Aphthona spp. insects were collected from established populations. These insects provided the basis for research and demonstration projects within the program. Operations developed and provided a standardized electronic scanable data collection form, used by all research assessment teams within the four state area and provided spreadsheets of the data for their use in interpreting insect establishment and leafy spurge control. Operations supported and hosted nine tours and field demonstrations in four states, developed "Leafy Spurge Biological Control Information and Photo Resource Gallery" CD, and provided information and support for the development of CD multimedia biological control information suite, including: Biological Control of Leafy Spurge Brochure, Power Point presentation, Biological Control Photos, and Information and Resources.
