resentations on citrus thrips, katydid and earwig citrus fruit scarring were made by Jay Rosenheim, Bodil Cass and Hanna Kahl on Aug 21 at a Lindcove Research and Extension Center field day. Exciting new data from their research conducted at LREC shows that thrips, earwigs and katydids dislike feeding on citrus fruit in the Tango group (Citrus reticulata) and this confirms PCA and grower observations that this mandarin variety does not require insecticide treatments for these pests. Other mandarin varieties show varying levels of susceptibility. Beth Grafton-Cardwell and Stephanie Doria discussed their current citrus thrips insecticide trial and best practices for managing thrips.
