The UC IPM Citrus Pest Management Guidelines has been updated to include new research out of the Rosenheim lab at UC Davis. Early-season pests like citrus thrips, earwigs, and katydids damage some types of mandarins differently. Learn how to adjust your management program accordingly. Many new photos have been added to these sections to improve pest identification and show more damage symptoms.
