Dull gray in color, Hydrellia sp. is widespread in the Philippines. The maggots feed on the unopened whorl of the leaf by remaining in the center of the whorl and nibbling the innermost margin of the leaf. The symptoms manifest as small chewed discolored areas on the innermost margin of the central whorl. Severe infestation stunts the plant and reduces tillers in a given hill. The infestation and damage are limited to vegetative stages of the crop.
Industry:Agriculture
The Asian rice gall midge, Orseolia oryzae, is a serious pest of rice in South and Southeast Asia. The adult gall midge is about the size of a mosquito. Gall midge attack starts in the seedbed and continues until the booting stage, but most of the damage is limited to the vegetative growth stages. The damage changes rice tillers into tubular galls, which dry without bearing panicles. New tillers are initiated as the older ones are infested, causing profuse tillering and stunting of the plants. A related species, O. oryzinova, is prominent in Africa.
