自然种群的无脊椎动物宿主的病毒，细菌，原生动物或蠕虫感染的调节进行了讨论，使用模型，结合联合收割机元素的传统流行病学（其中的主机人口是假定恒定的）与动态元素从捕食者-猎物的研究;无脊椎动物中明显缺乏获得性免疫简化了分析。高致病性感染，具有长期的感染阶段，往往会在其宿主群体中产生循环行为。该模型给出了解释的9-10年的人口周期的落叶松芽蛾（Zeiraphera diniana）在欧洲阿尔卑斯山，并建议微孢子虫原生动物和杆状病毒感染可能是负责5-12年的人口周期观察到许多温带森林昆虫。
The regulation of natural populations of invertebrate hosts by viral, bacterial, protozoan or helminth infections is discussed, using models that combine elements of conventional epidemiology (where the host population is assumed constant) with dynamic elements drawn from predator-prey studies; the apparent absence of acquired immunity in invertebrates simplifies the analysis. Highly pathogenic infections, with long-lived infective stages, tend to produce cyclic behavior in their host populations. The models give an explanation of the 9-10 yr population cycles of the larch bud moth (Zeiraphera diniana) in the European Alps and suggest that microsporidian protozoan and baculovirus infections may be responsible for the 5-12 yr population cycles observed in many temperate forest insects.
