Rice leaf miner (Lirionyza sativae) present at 24 villages and towns of 6 counties in Luan prefecture. The host of the pest covered 26 species of 10 families. Among them the main hosts were leguminous and cucurbitaceous plants. The insect can survive 8-10 generations under natural conditions. The damage caused by the pest was light in May and July and became gradually serious from August to October. The insect was transferred into greenhouse to continue to damage plants and was overwinter in mid-late November. The chemical control was very important and the spraying time should be taken when the rate of leaf infested was up to 20%. The successive 2-3 spraying with Abamectin and Bisultap can effectively control the pest.
