Bioassays for Testing the Efficacy of Ground Sprayed Insecticides for Gypsy Moth Eradication Programs in California    (View PDF)

Jeffrey C. Miller, Valerie Brown, Robert V. Dowell

Abstract: The insecticides Bacillus thuringlensis (BT), carbaryl, and diflubenzuron were tested in a field-laboratory study for the effect of killing first through third instar gypsy moth larvae on foliage of valley oak trees in California. Larval mortality differed significantly between the BT, the other insecticides and the check treatments. Also, the effects of all three of the insecticides were still apparent 28 days posttreatment.
