A field day was dedicated to discussing information on citrus thrips biology, damage, and management options available. Event kicked off by asking questions to the 42 participants about their pest management needs. Dr. Sandipa Gautam talked about citrus thrips biology and fruit scarring damage on different citrus varieties. Data on citrus thrips resistance to Delegate showed that resistance in San Joaquin Valley populations of citrus thrips is increasing and this is confirmed by PCA and grower observations. This year seemed to be a problem year for citrus thrips, with growers spraying up to five times to control thrips. Dr. Beth Grafton-Cardwell discussed citrus thrips trials screening different chemicals and emphasized the importance of using different class of pesticides for resistant management in citrus thrips.
