利用差分方程模型分析了在资源有限但有利的温度条件下昆虫的单化和二化生命周期的选择，该模型包括基于进化稳定策略的概念框架的密度依赖的种群动态。该模型预测，当产生第二代的与密度无关的年增长率部分超过单化型滞育期间的存活率时，二化型可以在单化种群中传播，但二化型的垄断是不可能的，除非它达到超过单化型的平衡种群密度。讨论了模型预测在解释温带主要单化种群中部分二化循环发生的适用性。
Selection for univoltine and bivoltine life cycles in insects under resource‐limited but favourable temperature conditions is analyzed with a difference equation model including density‐dependent population dynamics based on the conceptual framework of an evolutionarily stable strategy. The model predicts that the bivoltine type can spread in a univoltine population when the fraction of density‐independent rate of annual increase by producing a second generation exceeds the survival rate during diapause of the univoltine type, but monopoly of the bivoltine type is not possible unless it attains an equilibrium population density exceeding that of the univoltine type. The applicability of the model prediction in explaining the occurrence of a partial bivoltine cycle in predominantly univoltine population in the temperate zones is discussed.
