Biocontrol Factsheets

The North American Invasive Species Management Association (NAISMA) Classical Biocontrol Committee is excited to announce new peer-reviewed weed biocontrol publications for use by managers and landowners. Subject matter experts are developing a series of factsheets that cover invasive plants and their associated biological control agents in North America. Eighty factsheets for 40 systems will soon be available.

  • The weed factsheet covers plant identification, history, distribution, ecology, habitat, and comparisons to look-a-like species.
  • The biocontrol agent factsheets provide information on agent identification, life cycle, impact, habitat requirements, history and current status for all biocontrol agents or accidentally introduced species associated with their host plant species.

Each publication is peer-reviewed and designed to help everyday landowners and weed managers identify and understand weed species and learn about their biocontrol agents.
