Thrips can be often found on the leaf sheath near the collar or inside the leaf sheath. They will quickly run/hop when disturbed. Both larvae and adults feed on young rice plants.
Thrips injure plants by using a scraping mouthpart to macerate (tear) the leaf tissue, and then extract the plant liquids. This causes desiccation and would typically not be a problem, except for the dry, windy conditions.
The numbers of thrips in rice field are usually below level justifying insecticide treatment, but they may increase rapidly under favorable conditions.
