摘要: 本文报道了长兴岛桔粉虱生活史及习性、自然种群生命表资料以及大田种群动态,并研究了杀虫剂对桔粉虱的影响。桔粉虱在长兴岛一年发生3代,以Ⅳ龄若虫越冬。各虫态中卵及Ⅳ龄若虫死亡率最高,Ⅱ龄若虫较低,每年3代中以第2代死亡率最高。桔粉虱存活率曲线属威布尔模型的第Ⅲ型。大田种群动态资料以种群年龄结构为特征反映了粉虱的田间数量消长及杀虫剂对其影响。对防护林女贞树上的粉虱种群动态进行分析,并将粉虱作为江原钝绥螨的交替饲料进行了讨论。

Abstract: On Changxing island of Shanghai, whitefly occurs yearly three generations, with the 4th instar nymph overwintering there. In each stage, the death rate of eggs and 4th instar nymph is highest, and that of 2nd instar nymph is lowest. The survival curve of population is subjected to the weibull model type Ⅲ. The field population dynamics characterised by age structure reflects the growth and decline of whitefly in field and the effect of pesticide on them. The population dynamics of citrus whitefly on privet tree is analysed as well, and the roles of citrus whitefly served as alternate foods ofpredacity mite (Amblyseius eharai) are also discussed.
