Abstract
為害十字花科之蔬菜害蟲，種屬繁多，就鱗翅類而言，以粉蝶科（Pieridae）之Pieris，屬幼蟲最為常見。過去有綠點粉蝶Bferis canidia sordida Butler在臺灣平原地帶為害，近時又有白粉蝶Pieris rapae crucivora Boisduval相繼出現，成為冬季蔬菜十字花科之主要害蟲。查白粉蝶原分佈於大陸，在本省僅發生於高山地帶，近因橫貫公路築成後，高山與平地交通頻繁，原限於棲息高山之害蟲，往往隨之遷移，適應平地環境而衍生，以致平原地區之昆蟲相有所改變。筆者在冬季採集時，常有新害蟲發見，如大陸為害豆科之豆捲葉蛾Lamprosema indicata Fabricus，去冬曾首次發見於臺北水源地，又為一例。故吾人對害蟲相之調查，及其天敵之利用研究，均可謂當前植物保護之重要課題，筆者爰將今春在臺北附近調查所得之菜粉蝶寄生性天敵，提出報告，同時列舉我國五種菜粉蝶之檢索表附於文後，以便鑑別，藉供同道參閱。
Brachymeria (Bracbymeris) obsurata (Walker) (Chalicidae) and Ptermoalus puparum (Linne) (Pteromalidae) parasited in the pupa of Pieris rapae Linne were found on this island. The former only one and the later 50 adults over were emerged from a single pupa. The total percentage of parasitism was 80% only. Morphology and habits of the adults were described detailedly.
