This book was released on 2010-07-01 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the results of recent research on aphid population dynamics and ecology relevant to current environmental changes resulting from global wa- ing. It incorporates a selection of the contributions presented at the International Symposium on Aphids in Fremantle, Australia, in October 2005, plus some ad- tional invited chapters. The objective was to incorporate the major issues in the ?eld and simultaneously create a closely interrelated and integrated volume. The ?rst chapter sets the scene. Kindlmann and Dixon present a critical review of existing models of aphid population dynamics, examine the biological assumptions that are incorporated in the models and present one of the latest models of aphid metapopulation dynamics. They conclude that natural enemies are unlikely to affect aphid population dynamics late in a season, but in some years may have an effect very early in the season, when aphid colonies are still small and predators might be able to reduce the numbers of colonies. The question, whether aphids will move to different locations, adapt to the change in conditions in their current habitat or go extinct is discussed by Ameixa. She concludes that the distributions of aphids are most likely to change, with the distribution of each species moving globally as their preferred habitat moves in response to changes in the climate, which may be more dif?cult than in the past because of habitat fragmentation and habitat loss.

Available in PDF, EPUB and Kindle. Book excerpt: Pests cause damage to the economic value of crops and stored products, while vectors are responsible for the transmission of disease-causing agents in human beings and livestock. Although application of synthetic pesticides in agriculture gives immediate relief, it also causes well-known side effects, leading to a consensus among entomologists and agriculturists to shift towards other ecofriendly pest management methods. Natural enemies of insects including their predators, parasitoids and pathogens have attracted the attention of scientists across the globe. These natural enemies exist in agroecosystems and suppress the populations of pests. Parasitoids are farmers’ friends and the most successful group of natural enemies. Highly specialized/generalized in their prey choice, active stages of predators search for a suitable prey, attack or kill the prey and consume prey within a short handling time. Predatory ability is known to increase with increase in prey density. A single predator may devour several prey individuals. Exploiting this potency of parasitoids may yield successful results in controlling notorious pests in an ecofriendly way. This book provides information on the important biocontrol agents that are effective in pest suppression. It starts with insect parasitic groups followed by specific group of parasitoids. It is hoped that the book presents a comprehensive account of beneficial parasitoids and will be useful to undergraduate and postgraduate students of Entomology, Biological Control, Plant Protection, Agricultural Zoology and Zoology, besides those involved in competitive examinations and policy planning. Features Each chapter has been authored by specialized senior professionals Every chapter contains Learning Objectives and Points to Remember This book offers comprehensive knowledge of parasitoids and their application in pest management in a lucid way

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.
