| 摘 要： | 日本刀角瓢虫是粉虱类害虫的重要捕食性天敌之一、本文详细地描述了日本刀角瓢虫的形态特征，并附有各虫态的特征图。且对日本刀角瓢虫的生活习性进行了观察、以烟粉虱卵为食料，日本刀角瓢虫世代发育历期平均为22．56天，成虫平均寿命为9l94天，平均每雌产卵量为564．8粒：以烟粉虱若虫为食料，日本刀角虫世代发育历期平均为21．70天，成虫平均寿命为81．62天，平均每雌产卵量为650．0粒：瓢虫可捕食烟粉虱的卵、若虫、“蛹”、成虫各虫态，是烟粉虱的有效天敌，具有很好的保护利用价值。

| Abstract: | Serangium japonicum is one of the important predators of Bemisia tabaci. The morphological and biological characters of S. japonicum were studied in the laboratory. While feeding on eggs of whitefly, the average durations of a generation of Sjaponicum was 22.56 days, the adult average longevity was 91.94 days, the average fecundity was 564.8eggs per female. While feeding on nymphs of whitefly, the average durations of a generation of S. japonicum was 21.70 days, the adult average longevity was 81.62 days ,the average fecundity was 659.0 eggs per female. It can prey on all stages of B. tabaci, including eggs, nymph, pupae and adults. Its high consumption, fecundity and dispersal rates made it a potential biological control agent against B. tabaci. |
