Journal of the Iowa Academy of Science: JIAS
Purple loosestrife (Lythrum salicaria) is an invasive plant species infesting wetlands in North America. Biodiversity and wetland habitat quality are reduced following purple loosestrife establishment. Several management tactics, including cultural, mechanical, and chemical controls, have had limited success in reducing the spread of purple loosestrife. Beginning in the 1990s, a biological control program has introduced several species of natural enemies from Europe that feed on purple loosestrife. Since 1994, Iowa State University has reared and released two species of beetles that feed on purple loosestrife, Galerucella calmariensis and G. pusilla. Biological control is one component of an integrated purple loosestrife …

Purple loosestrife is a noxious weed quickly invading Nebraska's wetlands. This publication describes the rearing and releasing of insects for biological control of the weed, as one part of an integrated management program. Purple loosestrife is a noxious perennial weed invading thousands of acres of wetlands and waterways in the Midwest. In Nebraska an estimated 18,000 acres are already infested by this plant, mostly along the main rivers and waterways. It has no natural enemies in North America, therefore it is very hard to prevent it from spreading. For years people have tried to eradicate it, especially in the Great …
