The population effects of known fluctuations in fecundity and mortality of T. infestans was studied through simulation using Leslie matrices. The effect of mortality and fecundity cycles was a stepped cycling through the growing phase, with no significant population decreases. Density dependent regulation stabilizes changes during the steady phase. The main effect is on population composition with the establishment of a regular annual cycle in the proportion of different age groups. Cycles with high number of larvae may be misinterpreted as an adult plague.
利用莱斯利矩阵通过模拟研究了已知的南美锥蝽繁殖力和死亡率波动对种群的影响。死亡率和繁殖力周期的影响是在增长阶段呈阶梯式循环，种群数量没有显著减少。密度依赖调节使稳定阶段的变化趋于稳定。主要影响在于种群组成，不同年龄组的比例建立了规律的年度周期。幼虫数量多的周期可能会被误解为成虫灾害。
