In this dissertation , the interactive system of delphastus catalinae ( horn ) , its preys and competitor was studied , including comparison between alternative preys and natural prey consumed by d . catalinae ; the system of d . catalinae and its preys ; morphology comparison between d . catalinae and its competitor serangium japonicum chapin ; biology , ecology and predation of s . japonicum ; and also the interspecies competition between d . catalinae and s . japonicum . 1 . besides whitefly pests , d . catalinae could also feed on two species of alternative preys : tetranychus nr Fijiensis和桃蚜myzuspersicae ( sulzer ) ，并在实验室条件下，以自然猎物烟粉虱bemisiatabaci为对照，研究了替代猎物对小黑瓢虫的发育、存活、繁殖及对实验种群增长的综合影响，结果表明： ( 1 )小黑瓢虫以蚜虫为猎物时，成虫不会产卵，但可延长成虫的寿命；以红蜘蛛为猎物时，成虫可产卵并可完成整个世代。
