中文摘要 | 從埔里非洲菊及美國芹菜上所採得之白粉蝨,經鑑定為溫室粉蝨 (Trialeurodes vaporariorum (Westwood))。本害蟲在設施栽培之美國芹菜、非洲菊 為害頗為嚴重,此外於扁蒲、胡瓜、龍吐珠、野莧上亦可發現其危害,顯示該蟲 已在台灣中部立足,並擴散蔓延中。經緊急于美國芹菜上進行田間及室內藥劑試 驗結果,已從17種供試藥劑中,選出2.8% Decis E.C.等8種合成除蟲菊劑,對 溫室粉蝨具極優之殺蟲效果。施藥時應將藥液均勻噴到粉蝨棲息之葉背部位,間 隔5∼7天,連續施藥2∼3次。 |
英文摘要 | The whitefly collected from gerbera and celery leaves has been identified to be the greenhouse whitefly, Trialeurodes vaporariorum (Westwood), the third species of this genus recorded in Taiwan. During June and July 1988, the gerbera and celery grown in some nethouses were found to be severely damaged by this pest; subsequently this insect pest was observed on cucumber, bottle gourd, bleeding heart, glarybower, slender amaranth. It appeared that this pest had already established and was spreading quickly in central Taiwan. Laboratory and field screening 17 insecticides, for control of the pest showed that 8 compounds belong to pyrethroids were effective against the whitefly on celery. Two to three sprays of the insecticides with 5-to 7-day interval could effectively reduce the population of this insect pest. |
