稻叶毛眼水蝇(Hydrellia sinica Fan et Xia)又称水稻螳螂蝇、水稻潜叶蝇,为我国东北稻区水稻重要害虫,长江中、下游稻区亦有为害。近年来,东北地区山于水稻育苗方法的改进,插秧期显著提前,使稻叶毛眼水蝇由过去只限于秧田期为害,变为移栽后本田前期为害为主,对水稻生产的威胁更大。稻叶毛眼水蝇的幼虫潜入水稻叶片组织内取食叶肉,叶片腐烂,轻者水稻生育受到阻碍,重者死苗。水稻插秧后受害,返青期延长,造成“大缓苗”现象,并显著减少分蘗,抽穗期延迟,贪青晚熟,对水稻产量影响很大。稻叶毛眼水蝇在吉林地区一年发生4代,世代重叠,为害水稻的是第一代幼虫及早期发生的第二代幼虫。5月中旬—6月中旬对水稻 Hydrellia sinica Fan et Xia, also known as rice praying mantis and rice leaf miner, is an important pest of paddy rice in the northeast rice area of ​​China, and rice in the middle and lower reaches of the Yangtze River. In recent years, the Northeast mountain in rice seedling raising method improved, significantly earlier during the transplanting period, so that the leaf-sided water flies by the past limited to seedling damage, transplanting into the main Honda prejudice, the threat to rice production more Big. The larvae of the rice leaf fly waterfly sneaked into the leaves of rice plants to eat the mesophyll, leaf decay, the light of the rice growth was hampered, severe dead seedlings. Damage to rice after transplanting, returning to green prolongation, resulting in “big Huanmiao” phenomenon, and significantly reduce the tillering, heading delay, greyish late maturity, a great impact on rice yield. Ophiopogon japonicus occurs in four generations a year in Jilin area, overlapping for generations. The first generation larvae and the second generation larvae that prey on rice are the rice harmed. From mid-May to mid-June on rice
