摘要

在2015年1月至2016年6月間於新北市的輔仁大學校園內進行香蜂草上害蟲組成的調查，共紀錄有21種以鱗翅目（13種）為主的害蟲，並與盧氏葉螨、粉蝨與介殼蟲構成香蜂草的主要害蟲。其中，對香蜂草感染率達最高者為盧氏葉螨但其天敵隱翅蟲或可有效控制其族群，而鱗翅目的主要天敵為寄生蜂類。另外，發現有香蜂草上的害蟲種類組成在台灣南部（高雄市鳳山、田寮、阿蓮、美濃及大樹）與北部（新北市輔仁大學）間出現明顯的差異，且北部的害蟲種類亦較南部多，可能與田間條件不同有關。

From January 2015 to June 2016, a monitoring of pest on herb plant, Melissa officinalis L., was conducted at the campus of Fu- Jen Catholic University, New Taipei City. Twenty-one species have been recorded, whereby the lepidopteran pest has the highest abundance among the 13 species including mite, whitefly and scale insect that constitutes the majority of pest on lemon balm. The mite species, Tetranychus ludeni, could reach 100% infection rate for the plant but could also be reduced by its natural enemy, a rove beetle species close to Holobus flavicornis. Among the lepidopteran pests, parasite wasps play a major role in reduction of the number of pest. The difference in species composition of pest on lemon balm between northern (Fu Jen Catholic University) and southern (Fongshan and neighboring townships) Taiwan was significant. The number of species in northern Taiwan was higher than the south probably due to the field conditions.
