Laboratory Screening and Field Bioassays of Insecticides for Controlling the Balsam Woolly Adelgid in Southern Appalachia

摘要

Two concentrations of 13 insecticides and 3 fatty acids were screened in the laboratory against the balsam woolly adelgid (Adelges piceae (Ratz.)). Effkacy was judged on the percentage of dead adults and the number of living crawlers 24 hours after application. The top candidate materials, including lindane, were field bioassayed. Permethrin (Pounce or Ambush), chlorpyrifos (Dursban) and chlorpyrifos-methyl (ReIdan) were identified as potential replacements for lindane in controlling this insect.
