Tomato Russet Mite

Aculops lycopersici

  • Adult: very tiny (barely visible with a 10x lens), yellow, wedge-shaped mites with only 2 pairs of legs. EGG: round, clear, almost the same width as adult.
  • Nymph: two stages similar in appearance to adult but somewhat smaller.
  • Generation Time: rapid, 8 days in summer, 15 or so in cool weather.
  • Damage: affected leaves and stems first appear greasy, then turn bronze and may desiccate in hot, dry weather. Lower leaves are first affected. Rarely a pest in Florida except in protected culture.
