【Abstract】 Liriomyza sativae usually has 9 generations a year in Shanxi Province under natural conditions, but in special years, it has 8 or 10 generations. From late autumn to spring of next year, the leafminer continuously happens for 3～4 generations(from November to March of next year) in greenhouse. It is proved by the experiment that L. sativae can not naturally overwinter in the regions above 35.N. However, the winter vegetable storerooms are its main overwintering place. The main habits of leafminer are also reported in this paper. Fig 3, Tab 7, Ref 14更多还原
