山西省美洲斑潜蝇发生规律及防治技术研究

Ocurrence and Control of Liriomyza Sativae Blanchard in Shanxi

美洲斑潜蝇是新近传入山西省的一种国际性检疫害虫。山西省54个县（市）均有发生，寄主作物有10科45种，瓜菜类受害后一般减产20％以上，虫情指数在11％－72．5％之间。该虫在山西省每年发生8－12代。温度、湿度是影响种群变动的重要因子。筛选对路的化学农药是大田防治的有效手段。

The american leaf miner Liriomyza sativae Blanchard was a new quarantine pest, and occuredin 54 counties of Shanxi province from 1994 to 1998. The host plants of the pest have 10 familise 45specles. The yield loss was above 20%, when vegetablle crops were damaged. There are 8~12generations each year in Shanxi. Temperature and RH were key factors irifluencing population dynamics.The new chemical insecticides have been sereened. The effect of control in the field is obvious.
