Abstract
The aim of this study is to analyze the interactions of endogenous and exogenous processes on the dynamics of insect populations. Effects of disturbances can not be studied in isolation but need to be integrated in studies encompassing all population interactions. The present study is based upon a long-term spatially explicit monitoring program of four insect herbivores on a perennial herb, their enemies and their food resources. Direct and indirect weather effects as well as habitat changes are investigated with the aid of time series analysis and some long-term experiments. The aim of the study is to develop predictive models for new environmental scenarios.
