Abstract
臺灣柑橘球粉介殼蟲之天敵，據調查有捕食性瓢蟲類兩種；即蒙氏瓢蟲 〔Cryptolaemus montrouzieri (Mulsant)〕及二星小黑瓢蟲 〔Scymnus (Nephus) ryuguus Kamiya〕；寄生性跳小蜂類多種，然臺灣北部則以廣角跳小蜂（Anagyrus sawadai Ishii）最重要。然而此三種天敵對球粉介殼蟲皆非為最有效之天敵。而其中又以蒙氏瓢蟲較有希望。 According to the present survey, 3 species of natural enemies of citus mealybug have been recorded, i. e. Anagyrus sawadai Ishii, Cryptolaemus montr-ouzieri (Mulsant) and Scymnus (Nephus) ryuguns Kamiya. Among them. C. montr-ouzieri and A. sawadai were the most effective. Although they play important roles, but they came out seemly so late, it had to artificial production and releasion for over coming the high population of citrus mealybug in early summer.
