摘要
本文探讨了异色瓢虫多态类型增长参数的差异。在实验室给定条件下，不同的多态类型在世代发育时间、净繁殖率、存活率和内禀增长力诸方面均存在着明显差异。这样的差异可能有助于理解该物种多态类型频率分布的时空变化、不同类型对环境的适应以及种群动态规律。
This paper dealt with the differences of population growth parameters among the polymorphic types in the lady-bird beetle,Harmonia axyridis Pallas.Reared in crowds,these showed the significant differences in developmental and reproductive rates,as well as population survivorship and in- trinsic growth rates under the given conditions. These differences may help to un- derstand the spatio-temporal change of polymorphism frequency distribution in the beetle and adaptation of the polymorphic types to environment,as well as population dvnamics.
