This paper introduces a novel general model based on Ordinary Differential Equations (ODEs) which is able to describe the population dynamics of a large class of insect pests. The proposed model is a physiologically-inspired generalization of a number of ad hoc models presented through the years in the literature. Its main feature is that it allows the systematic generation of a population model for a species by simply defining its key features, namely the sex ratio and the development, fertility, and mortality rates. The first part of the paper provides a detailed description of the model and shows that most ODE-based models existing in literature can be obtained as a special case of the proposed model. The second part of the paper shows an application of the model to the spotted wing drosophila Drosophila suzukii, which is a highly relevant pest in agriculture. The biological features of this species, i.e., the sex ratio and the various rates, were retrieved from the existing scientific literature. The obtained model was validated using data from a three-year survey conducted in two experimental fields. Results show that the model describes faithfully the experimental populations, although the simulations were performed completely in open-loop and without any adaptation of the parameters extracted from the existing literature.

本文介绍了一种基于常微分方程 (ODE) 的新型通用模型，该模型能够描述一大类害虫的种群动态。所提出的模型是对多年来文献中提出的许多特别模型的生理启发的概括。它的主要特点是它允许通过简单地定义一个物种的关键特征，即性别比和发育、生育率和死亡率来系统地生成一个物种的种群模型。论文的第一部分提供了模型的详细描述，并表明文献中存在的大多数基于 ODE 的模型都可以作为所提出模型的特例获得。论文的第二部分展示了该模型在斑点翅果蝇中的应用铃木果蝇，这是一种高度相关的农业害虫。该物种的生物学特征，即性别比和各种比率，是从现有的科学文献中检索到的。使用在两个试验田进行的为期三年的调查数据对获得的模型进行了验证。结果表明，该模型忠实地描述了实验群体，尽管模拟完全是在开环中进行的，并且没有对从现有文献中提取的参数进行任何调整。
