PRF/J: The Dynamics of a Two-Species Prey/Predator/Parasite System: Interactions Between the Ciliate Lambornella clarki and the Mosquito Larva Aedes sierrensis

这将是一个三营养水平的定量研究， 两种西方树洞蚊之间的相互作用 谢伦伊蚊和拉氏纤毛虫。 三款车型 将采用：两个将比较一般的3种猎物/ 捕食者/寄生虫系统，以探索独特的性质， 互动，而第三种模式将纳入规模结构 年龄结构特征等。 模型 分析的重点是了解三种幼虫 死亡率：过度代偿、代偿和失代偿， 每一种都在不同的食物来源下观察到 条件 敏感性分析将用于确定 参数导致各种死亡类型。 最后通过设计的实验对模型进行了验证 测试模拟结果。 %%% 污染问题与昆虫对传统杀虫剂的抗药性 需要审查替代控制方法。 的 生物防治剂的潜力很大，因为它们 目标专一性 预计这项调查将 大大提高了我们对昆虫 自然界中的死亡率（例如，它们是否依赖于密度？）。 研究结果对指导害虫防治策略非常有用 一般来说。

This is to be a quantitative study of the tri-trophic level, two-species interaction between the western tree hole mosquito Aedes sierrensis and the ciliate Lambornell clarki. Three models will be employed: two will compare a general 3-species prey / predator / parasite system to explore the unique properties of the interaction, while a third model will incorporate size structure and age structure features in addition to extrinsic factors. Model analysis is to focus on understanding three kinds of larval mortality: over-compensatory, compensatory, and decompensatory, each of which has been observed under varying food resource conditions. Sensitivity analysis will be used to determine which parameters are responsible for causing the various mortality types. Finally the model is to be validated through experiments designed to test simulation results. %%% Pollution problems and insect resistance to traditional pesticides necessitate examination of alternative control methods. The potential for biological control agents is great due to their target specificity. It is expected that this investigation will significantly improve our understanding of mechanisms for insect mortality in nature (for example, are they density-dependent?). Results should be very useful in guiding pest control strategies generally.
