Dynamics of a host—parasitoid interaction system: Utida’s experimental study azuki bean weevil, . (L.), as host and the braconid wasp, . (Viereck), as parasitoid. The graphs are routinely cited in ecology text books as a typical example of a host—parasitoid oscillation. In this chapter, I shall delve into the causal mechanism underlying the dynamics of this classic experimental system.

In deducing such conditions, we shall gain insight into the basic properties and structure of animal population processes. The practical value of our deduction depends, of course, on how we set up the premises.

Regine Eibl,Sören Werner,Dieter Eiblpter, I shall discuss several types of mechanisms and examine their interrelations. Through such comparative studies, we gain insight into the way our ideas evolve. Understanding the ecological meaning of a model promotes further improvement in its applicability through systematic generalizations.

Structures and patterns of population processesIn this chapter, I set up some basic theoritical models and illustrate the patterns that they generate. By such exercises, we gain knowledge essential for guessing the unknown generating mechanism of an observed pattern (to be discussed in Chapter 3).

Dynamics of the spruce budworm outbreak processesDespite the obituary, the spruce budworm (. [Clem.], Lepidoptera: Tortricidae) is alive. It occurs along the North American boreal-forest zone, although tending to concentrate more towards the eastern part. Its chief foods are the needles of balsam fir, . (L.), and several spruce, ., species.
