• Abstract: Our research focused primarily on chemical control of the glassy-winged sharpshooter, Homolodisca coagulata, a pest of citrus and grapes in California. A number of insecticides from various classes of chemistry were incorporated into this study to evaluate their effectiveness against this pest as well as to establish baseline susceptibility data to each insecticide. The use of insecticides involves some resistance risks in most pests. As such, part of our research was undertaken to monitor the occurrence of any shifts in susceptibility to the principal control agents by comparing the toxicity values for the last two years. Comparison of susceptibility shifts will enable us to analyze the practical implications of any tolerances detected by incorporating such information into well-coordinated recommendations for delaying or combating resistance development in future management programs of this pest.
