Biological control is the suppression of pest populations using
predators, parasitoids and pathogens. Historically, biological
control has largely been on a trial-and-error basis, and has failed
more often than it has succeeded. However by developing theories
based upon fundamental population principles and the biological
characteristics of the pest and agent, we can gain a much better
understanding of when and how to use biological control. This book
gathers together recent theoretical developments and provides a
balanced guide to the important issues that need to be considered
in applying ecological theory to biological control. It will be a
source of productive and stimulating thought for all those
interested in pest management, theoretical ecology and population
biology.
The multitrophic level approach to ecology addresses the complexity
of food webs much more realistically than the traditional focus on
simple systems and interactions. Only in the last few decades have
ecologists become interested in the nature of more complex systems
including tritrophic interactions between plants, herbivores and
natural enemies. Plants may directly influence the behaviour of
their herbivores' natural enemies, ecological interactions between
two species are often indirectly mediated by a third species,
landscape structure directly affects local tritrophic interactions
and below-ground food webs are vital to above-ground organisms. The
relative importance of top-down effects (control by predators) and
bottom-up effects (control by resources) must also be determined.
These interactions are explored in this exciting volume by expert
researchers from a variety of ecological fields. This book provides
a much-needed synthesis of multitrophic level interactions and
serves as a guide for future research for ecologists of all
descriptions.
How is the staggering biodiversity of the parasitoid insects
maintained? This book, first published in 1994, explores patterns
in host-parasitoid interactions, including parasitoid community
richness, the importance of parasitoids as mortality factors, and
their impact on host densities as determined by the outcomes of
parasitoid introductions for biological control. It documents
general patterns using data sets generated from the global
literature and evaluates potential underlying biological,
ecological and evolutionary mechanisms. A theme running throughout
the book is the importance of host refuges as a major constraint on
host-parasitoid interactions. Much can be learnt from the analysis
of broad patterns; a few simple rules can go a long way in
explaining the major components of these interactions. This book
will be an invaluable resource for researchers interested in
community ecology, population biology, entomology and biological
control.
