Searching behavior is an active movement by which insects seek resources. It is an
important kind of behavior because insects thereby acquire food, mates, oviposition and …

The current concepts of host plant resistance to insects are reviewed in this book. The broad
coverage includes crop plant and insect diversity, mechanisms of insect-plant interactions …

This is a book about proximate mechanisms. Although some theoreti cal structure is used to
introduce the subject, the intent is to offer a comprehensive view of the mechanistic side of …

Populations that persist do so, not by a juggling act balancing their rate of increase against a
pot-pourri of unpredictable environmental factors, but rather by one or more processes that …

In butterflies and many other insects there is a general tendency for males to emerge before
females. This is known as protandry. In this paper we advance the hypothesis that protandry …

Over the past 40 years there has been an extraordinary effort to understand the relationships
of plant-feeding insects and their hosts. Anyone who is studying such problems knows the …

Unlike many insects, the caterpillars of the cabbage butterfly, Pieris rapae, are less
abundant on host plants that grow in large dense stands than on hosts that are scattered …

The study of weather effects in insect ecology should focus on how physiological and
behavioral characteristics of individual organisms translate into population and community …

We formalise some ideas on host choice by individual insects, into a model which allows an
animal to change diet during a lifetime. We assume that factors affecting acceptance …

Oviposition site selection and clutch size in parasitic insects can be viewed as problems in
foraging theory. In this paper, a number of models for site selection and clutch size are …
