Abstract

Efficacies of nine insecticides were compared for suppression of azalea lace bug (ALB) and effect on natural enemies. Examination of leaf samples collected weekly revealed reduced ALB populations in all treatments while six of the tested products required multiple applications for effective control. Acephate was the most cost effective treatment. Emergence of Anagrus takeyanus, an egg parasitoid of ALB, was observed in all treatments and increased during the study period.
