Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2020-03-31 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Insect Defenses written by David L. Evans and published by SUNY Press. This book was released on 1990-01-01 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work takes a fresh, modern approach to investigate and explain the predator and prey relationships of insects and spiders, the major terrestrial fauna on earth. Devoted to broad and in-depth analysis of arthropod defenses against predators, the book's approach is both experimentally and theoretically based with major emphasis on evolution, predator strategies and tactics, and prey defensive adaptations and behaviors. The authors explain such topics as cryptic and aposematic coloration, the conflict between sexual and survival needs, web spider prey choice and evolution of prey counter defenses, predator-prey interactions and the origins of intelligence, bird predatory tactics, and caterpillar defense strategies. Also examined is the use of timing for fitness and survival, evolutionary gamesmanship in the predatory bat-moth relationship, colony defense by aper wasps, startle as a defense by moths, aggregation as a defense, chemicals as defenses, plant chemicals as defenses, and venoms as defenses. The authors illustrate each topic with numerous specific well-documented examples presented in a clear, readable style.

Available in PDF, EPUB and Kindle. Book excerpt: Humans, being visually oriented, are well versed in camouflage and how animals hide from predators that use vision to locate prey. However, many predators do not hunt by sight; they hunt by scent. This raises the question: do survival mechanisms and behaviors exist which allow animals to hide from these olfactory predators? If so, what are they, a

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the fundamental issues of predator-prey interactions, with an emphasis on predation among arthropods, which have been better studied, and for which the database is more extensive than for the large and rare vertebrate predators. The book should appeal to ecologists interested in the broad issue of predation effects on communities.
Download or read book Insects as Natural Enemies written by Mark Jervis and published by Springer Science & Business Media. This book was released on 2005-05-25 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Consumer Resource Dynamics MPB 36 written by William W. Murdoch and published by Princeton University Press. This book was released on 2013-02-15 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite often violent fluctuations in nature, species extinction is rare. California red scale, a potentially devastating pest of citrus, has been suppressed for fifty years in California to extremely low yet stable densities by its controlling parasitoid. Some larch budmoth populations undergo extreme cycles; others never cycle. In Consumer-Resource Dynamics, William Murdoch, Cherie Briggs, and Roger Nisbet use these and numerous other biological examples to lay the groundwork for a unifying theory applicable to predator-prey, parasitoid-host, and other consumer-resource interactions. Throughout, the focus is on how the properties of real organisms affect population dynamics. The core of the book synthesizes and extends the authors' own models involving insect parasitoids and their hosts, and explores in depth how consumer species compete for a dynamic resource. The emerging general consumer-resource theory accounts for how consumers respond to differences among individuals in the resource population. From here the authors move to other models of consumer-resource dynamics and population dynamics in general. Consideration of empirical examples, key concepts, and a necessary review of simple models is followed by examination of spatial processes affecting dynamics, and of implications for biological control of pest organisms. The book establishes the coherence and broad applicability of consumer-resource theory and connects it to single-species dynamics. It closes by stressing the theory's value as a hierarchy of models that allows both generality and testability in the field.
