| 摘 要： | 小黑瓢虫(Delphastus catalirtae(Horn))是粉虱害虫的重要捕食性天敌。本对小黑瓢虫从英国引种后的形态特征和生物学特性进行观察，用福州地区新的猎物寄主高氏瘤粉虱(Aleurotubercutatus takahashii David＆Subramaniam)进行饲养繁殖，已成功地在室内定殖和繁衍。小黑瓢虫成虫寿命长达90—130天．可捕食粉虱卵、若虫、成虫各虫态，且捕食量大，活动能力强，是高氏瘤粉虱的有效天敌，具有很好的保护利用价值。

| Abstract: | The paper deals with the characters and biology of the little black ladybird beetle Delphastus catalinae (Horn), which is an important predator as biological control agent for the whitefly pests and was introduced from UK into China in 1996. The whitefly Aleurotuberculatus takahashii David & Subramaniam is first used as the host to rear the little black ladybird beetle successfully in the laboratory in Fuzhou of China. The little black ladybird beetle can predate on the egg, nymph,pupa and adult of the whitefly, with high activity and large predating quantity. |
