Thrips Can Cause Damage To Orange Crop

[Millet]

The telltale ring scarring on navel oranges and other citrus is the work of citrus thrips, Scirtothrips citri, a pest that can have a major economic impact on fresh-market crops. Controlling citrus thrips is essential to protecting fruit quality and the accompanying price premium. With citrus thrips, the second-instar larvae do the most damage, feeding mainly under young fruit sepals. As the fruit grows, the damage moves outward, creating the familiar ring-shaped scarring. Fruit is most susceptible to thrip damage after petal fall and until it’s about 1½ inches in diameter. As a result, control treatment made at petal fall is most effective.
