Stink bug feeding.
Fruit are covered with white or yellow flecks and patches that occur in the tissue just beneath the skin. Peeling fruit in the affected areas reveals white corky (not red) tissue.
Stink bugs often attack tomatoes from surrounding weeds. Feeding on young fruit is barely noticeable, but improper ripening and blemishes develop as fruit matures. Use a recommended insecticidal program to control stink bugs.
