Systemic Treatment with Acephate for Gypsy Moth Management: Population Suppression and Wound Response

Abstract

Oaks were treated with acephate containing ACECAPs or Mauget Inject-A-Cide 0 units 1984 and/or 1 985. In 1985, both twice-treated (treated in 1984 and 1985) and once-treated (treated only in 1985) oaks had significantly fewer gypsy moth egg masses per tree than did control trees, and twice-treated oaks had fewer than those treated only in 1984. Implantation/injection did more damage to white oak than to red oak group trees.
