ANS Outreach: Biological Control of Purple Loosestrife by 4-H Volunteers--MN Component

Purple loosestrife (Lythrum salicaria) is a European plant species which is an aggressive invader of North American coastal wetlands. Once established, purple loosestrife forms impenetrable monospecific stands significantly reducing biodiversity and degrading coastal wetland quality. This species is now controllable with natural enemies (beetles), and several Great Lakes states have developed limited control programs. The challenge is to establish viable populations of loosestrife s natural enemies in all Great Lakes wetlands. At present, professional staff resources can manage biocontrol releases on just a handful of sites per year. By training and supporting 4-H groups interested in rearing these natural enemies, it will be possible to greatly multiply the number of beetles reared and release sites impacted.
