抽象的。[1]假设没有净迁移和恒定的死亡率，模拟了离散世代中出现的成年昆虫丰度的时间过程。假设至出现的时间是逻辑分布的。2模型的定性特征仅依赖于一个无量纲参数，即死亡率与对称涌现分布的离散测度的乘积。3该模型适用于五种蝴蝶的丰度数据。乳头非常好;此外，估计的死亡率完全在文献中给出的范围内（大多数为0.1-0.2天-1）。死亡率通常通过标记再捕获方法获得。本模型提供了评估这些方法的一些假设的机会。
Abstract. 1 The time course of abundance of adult insects emerging in discrete generations is modelled, assuming the absence of net migration and a constant death rate. The time till emergence is assumed to be logistically distributed. 2 The qualitative features of the model depend on one dimensionless parameter only, namely the product of the death rate and a dispersion measure for the symmetric emergence distribution. 3 The model is fitted to data on the abundance of five butterfly species. The tit is excellent; moreover, the estimated death rates are well within the range given in the literature (mostly 0.1–0.2 day‐1). Death rates are generally obtained by mark‐recapture methods. The present model gives the opportunity to evaluate some assumptions of these methods.
