山西省菜田潜叶蝇的种类识别及其发生规律

Identification and Occurrence Regulation of Leafminers in Shanxi

调查结果表明,山西现已发现为害蔬菜的潜叶蝇害虫4种,即美洲斑潜蝇L.sativae Blanchard、南美斑潜蝇L.huidobrensis(Blanchard)、葱斑潜蝇L.chinensis(Kato)和豌豆彩潜蝇Chromatomyzia horticola(Goureau)。因其形体小,形态易混淆。从外部形态、取食、寄主等方面对4种潜蝇加以区别,同时总结了潜蝇在山西的发生规律,以供广大植保工作者参考。

Four kinds of leafminers were indentified which damage vegetables in Shanxi, and they are L. sativae Blanchard, L. huidobrensis （Blanchard）, L. chinensis （Kato） and Chromatomyzia horticola （Goureau）. These pests are difficult to identify due to their small size. This paper discusses the their differences form morphology and behavior in order to identify them and the occurrence regulation of these four kinds of leafminers in Shanxi.
