Much of our understanding about insect predator-prey dynamics has been due to studies on insect parasitoids. But do true predators such as ladybird beetles really operate in a similar way and how does this affect their use in biological control? The extensive literature on ladybirds as biocontrol agents shows that their size and rate of development is very dependent on the nature of their prey. This volume explores basic ladybird biology, their association with their prey and its effect on development rate and body size. Optimal foraging theory, field observations and laboratory experiments are used to illustrate how ladybird larvae maximise their rate of energy intake, and ladybird adults their fitness. The interdependence of these life history parameters is then used to develop a simple predator-prey model which, with an analysis of the literature, highlights the specific attributes of potentially successful biocontrol agents for all those interested in predator-prey dynamics.

This volume explores modern concepts of trophic and guild interactions among natural enemies in natural and agricultural ecosystems - a field that has become a hot topic in ecology and biological control over the past decade. It is the first book on trophic and guild interactions to make the link to biological control, and is compiled by internationally recognized scientists who have combined their expertise.

In this study of arthropod predador-prey systems Michael Hassell shows how many of the components of predation may be simply modeled in order to reveal their effects on the overall dynamics of the interacting populations. Arthropods, particularly insects, make ideal subjects for such a study because their generation times are characteristically short and many have relatively discrete generations, inviting the use of difference equation models to describe population changes. Using analytical models framed in difference equations, Dr. Hassell is able to show how the detailed biological processes of insect predator-prey (including host-parasitoid) interactions may be understood. Emphasizing the development and subsequent stability analysis of general models, the author considers in detail several crucial components of predator-prey models: the prey's rate of increase as a function of density, non-random search, mutual interference, and the predator's rate of increase as a function of predator survival and fecundity. Drawing on the correspondence between the models and field and laboratory data, Dr. Hassell then discusses the practical implications for biological pest control and suggests how such models may help to formulate a theoretical basis for biological control practices.

At last both ecology and evolution are covered in this study on the dynamics of size-structured populations. How does natural selection shape growth patterns and life cycles of individuals, and hence the size-structure of populations? This book will stimulate biologists to look into some important and interesting biological problems from a new angle of approach, concerning: - life history evolution, - intraspecific competition and niche theory, - structure and dynamics of ecological communities.

Insect Predators unveils the hidden world of these tiny hunters, showcasing their crucial role in maintaining ecological balance and shaping biodiversity. The book explores how these creatures, often overlooked, employ diverse hunting strategies, from the ambush tactics of mantises to the chemical warfare of assassin bugs. Readers will discover the evolutionary arms race between predators and prey, a dynamic that drives adaptation and influences entire ecosystems. This exploration dives into the specialized hunting behaviors, physical adaptations, and life cycles of various predatory insect groups. Through observational studies and experimental research, the book highlights intriguing facts, such as the mantis's camouflage and lightning-fast strikes or the dragonfly's remarkable aerial hunting skills. Each chapter provides an in-depth analysis of a particular insect group, progressing from an overview of insect predation to a broader discussion of their ecological implications. The book takes a holistic approach, integrating behavioral ecology, evolutionary biology, and conservation science to provide a nuanced understanding of insect predation. It emphasizes the importance of considering both the predator's and prey's perspectives. By connecting interdisciplinary fields, Insect Predators offers valuable insights into developing sustainable pest management strategies and conserving insect diversity.

Feeding on Non-Prey Resources by Natural Enemies Moshe Coll Reports on the consumption of non-prey food sources, particularly plant materials, by predators and parasitoids are common throughout the literature (reviewed recently by Naranjo and Gibson 1996, Coll 1998a, Coll and Guershon, 2002). Predators belonging to a variety of orders and families are known to feed on pollen and nectar, and adult parasitoids acquire nutrients from honeydew and floral and extrafloral nectar. A recent publication by Wäckers et al. (2005) discusses the p- visioning of plant resources to natural enemies from the perspective of the plant, exploring the evolutionary possibility that plants enhance their defenses by recru- ing enemies to food sources. The present volume, in contrast, presents primarily the enemies’ perspective, and as such is the first comprehensive review of the nut- tional importance of non-prey foods for insect predators and parasitoids. Although the ecological significance of feeding on non-prey foods has long been underappreciated, attempts have been made to manipulate nectar and pollen ava- ability in crop fields in order to enhance levels of biological pest control by natural enemies (van Emden, 1965; Hagen, 1986; Coll, 1998a). The importance of n- prey foods for the management of pest populations is also discussed in the book.

Over the past three decades there has been a dramatic increase in theoretical and practical studies on insect natural enemies. The appeal of insect predators, and parasitoids in particular, as research animals derives from the relative ease with which many species may be cultured and experimented with in the laboratory, the simple life cycles of most parasitoids, and the increasing demand for biological pest control. There is now a massive literature on insect natural enemies, so there is a great need for a general text that the enquiring student or research worker can use in deciding on approaches and techniques that are appropriate to the study and evaluation of such insects. This book fulfils that demand. A considerably updated and expanded version of a previous best-seller, it is an account of major aspects of the biology of predators and parasitoids, punctuated with information and advice on which experiments or observations to conduct, and how to carry them out. Guidance is provided, where necessary, on the literature that may need to be consulted on particular topics. While researchers can now refer to several books on parasitoids and predators, Insects as Natural Enemies is unique in emphasising practicalities. It is aimed at students and professional working in universities and both government and commercial institutes in the fields of pest management, agriculture, horticulture and forestry.
