EFFECTS OF AN OPERATIONAL APPLICATION OF DIMILIN® ON NON-TARGET INSECTS

Abstract
Effects of an operational application of Dimilin® on non-target insects were evaluated in eastern West Virginia in 1988 and 1989. Dimilin was applied in 1988 (70,75 g AI per ha). Insects were collected by light-traps at seven pairs of Dimilin-treated and control sites. Lepidoptera experienced the greatest impact, displaying reduced abundance and species richness at treated sites. No effects were observed among Coleoptera, Diptera, or Hymenoptera.
