Rice midge harms rice, how can it be controlled effectively?
Rice midge, commonly known as red worm or red thread worm, damages the young roots and young shoots of rice with its larvae, causing floating seedlings, and feeds on the embryo and endosperm of ungerminated seeds, preventing the seeds from germinating. Rice seedling fields and direct-seeded fields suffer severe damage. The adult is a small moth, with wings shorter than the body; when resting, the front legs are raised and swing up and down. The larvae are red or pale yellow, with a limb-like protrusion on the ventral side of the prothorax. It occurs 2-3 generations per year, and the first generation damages rice. It overwinters as nymphs and adults in weeds. Adults appear in early May of the second year, and lay eggs in late May.
