Vector survival rate is a key factor when estimating the potential of a vector population to transmit a parasite and as such, a small change in vector survival can have a significant effect on vectorial capacity. Using laboratory experiments, I investigated the possibility that Anopheles gambiae, a vector of Plasmodium, can alter the proportional allocation of resources between somatic and reproductive functions in response to limited nutritional intake. I also conducted a field survey to document how the nutritional status of An. gambiae varies within a population. Lastly, I used laboratory experiments to examine the effect of Plasmodium on vector fitness. The results of these investigations show that An. gambiae does have some control over its longevity, can mediate the effects of limited nutrition, that nutritional status of mosquitoes varies within a population and can alter the effect of Plasmodium on its vector.

This practical book covers all aspects of the biology of malaria vectors, with notes on the vectors of dengue. It is the first work in this field to concentrate on mosquitoes, rather than covering all disease vectors. Authored by renowned field entomologist Jacques Derek Charlwood, it disseminates his vast experience working on mosquito biology, ecology and the evaluation of new vector control tools across five continents over the past 40 years. Covering all aspects from classification and systematics, population dynamics, vector control, to surveillance and sampling, epidemics, and a selection of case histories, the book also considers genetics and resistance, Aedes biology, and malaria and dengue models. It is designed to fill the gap between very specialized texts and undergraduate books on general disease vectors, and is ideal as a textbook for postgraduate courses in entomology and mosquito vectors of disease.

Mir S. Mulla joined the faculty of the Entomology Department at the University of California, Riverside in 1956, only two years after the Riverside campus was established as an independent campus within the University of California system. Prior to his appointment, Mir received his B.S. from Cornell University and then moved to the University of California, Berkeley to pursue his graduate studies. His Ph.D. from Berkeley, awarded in 1955, completed his formal American education which was the purpose of his immigration from his native Kandahar in Afghanistan. In his over 50 years at Riverside, Mir has made an incalculable impact on vector biology both within the United States and in developing countries throughout the world. Within Southern California, Mir’s basic and applied research led to the rapid and sustainable control of mosquitoes and eye gnats in the Coachella Valley and so directly enabled this region to grow to the thriving, large community it is today. In 2006 his efforts in facilitating the development of the low desert of southern California were recognized through the dedication of the Mir S. Mulla Biological Control Facility by the Coachella Valley Mosquito and Vector Control District. His success has been so profound that it remains somewhat cryptic to the many who now reside in, visit, and enjoy, this region of California, oblivious to the insect problems that severely restrained development until Mir and his students ?rst applied their expertise many decades ago.

Vector-borne diseases continue to be one of the most important determinants affecting human and animal health. Large numbers of people suffer from diseases like malaria, dengue, filariasis and leishmaniasis, especially in the tropics. Whereas these diseases were eradicated from the temperate climate zones, in recent years the rising incidence of 'emerging' vector-borne diseases such as bluetongue, West Nile Virus, Lyme disease, tick-borne encephalitis and the recent outbreaks of chikungunya and dengue in southern Europe provide evidence that these diseases are resilient and can disperse to other regions and continents where before they were not present or relevant. Many tools for the management of vector-borne diseases are currently under pressure because of increasing drug and insecticide resistance, as well as the realization of biological variation of parasites and vectors and their ecosystems. At the same time, progress in our understanding of genetics, immunology, population biology and epidemiology allow for a better understanding of parasite-vector interactions. Here the state-of-the-art of these interactions is being reviewed, and means for using this information for advanced strategies of vector-borne disease control are proposed. This 3rd edition of ECVD aims to provide a rapid overview of recent developments in the field of parasite-vector interactions and how this can be used for more effective and sustainable disease control.

As malaria and other tropical diseases continue their resurgence, questions about the potential impacts of environmental and demographic factors are becoming more critical. Recent attempts to understand the increase in malaria incidence often acknowledge the importance of social, economic and other contextual variables, but fail to explicitly incorporate them into models or consider how they evolve in relation to one another. This problem is of crucial interest to the climate policy community, which has been buffeted by claims and counter-claims concerning the impact of climate change on malaria. This important volume examines the contextual determinants of malaria and attempts to develop methods for incorporating them into projections of future incidence. Internationally renowned health specialists, economists, and other social scientists provide regional and global perspectives on risk modeling, the history of eradication efforts, current determinants (including environmental, social, and economic factors), and prospects for new vaccines and drugs. The Contextual Determinants of Malaria argues that an association of climate change with increased malaria incidence will have at least as much to do with human aging, poverty, urbanization, and population movement as with a rise in global temperatures. By placing climate in this perspective, The Contextual Determinants of Malaria focuses attention on the public health needs most critical in both the immediate and long-term future. It encourages multidisciplinary analysis of malaria control, and improves our understanding of the interactions of the diverse range of factors involved in the incidence and spread of the disease.

Vector-borne infectious diseases, such as malaria, dengue fever, yellow fever, and plague, cause a significant fraction of the global infectious disease burden; indeed, nearly half of the world's population is infected with at least one type of vector-borne pathogen (CIESIN, 2007; WHO, 2004a). Vector-borne plant and animal diseases, including several newly recognized pathogens, reduce agricultural productivity and disrupt ecosystems throughout the world. These diseases profoundly restrict socioeconomic status and development in countries with the highest rates of infection, many of which are located in the tropics and subtropics. Although this workshop summary provides an account of the individual presentations, it also reflects an important aspect of the Forum philosophy. The workshop functions as a dialogue among representatives from different sectors and allows them to present their beliefs about which areas may merit further attention. These proceedings summarize only the statements of participants in the workshop and are not intended to be an exhaustive exploration of the subject matter or a representation of consensus evaluation. Vector-Borne Diseases : Understanding the Environmental, Human Health, and Ecological Connections, Workshop Summary (Forum on Microbial Threats) summarizes this workshop.

Malaria is an infectious disease like no other: it is a dynamic force of nature and Africa’s most deadly and debilitating malady. James C. McCann tells the story of malaria in human, narrative terms and explains the history and ecology of the disease through the science of landscape change. All malaria is local. Instead of examining the disease at global or continental scale, McCann investigates malaria’s adaptation and persistence in a single region, Ethiopia, over time and at several contrasting sites. Malaria has evolved along with humankind and has adapted to even modern-day technological efforts to eradicate it or to control its movement. Insecticides, such as DDT, drug prophylaxis, development of experimental vaccines, and even molecular-level genetic manipulation have proven to be only temporary fixes. The failure of each stand-alone solution suggests the necessity of a comprehensive ecological understanding of malaria, its transmission, and its persistence, one that accepts its complexity and its local dynamism as fundamental features. The story of this disease in Ethiopia includes heroes, heroines, witches, spirits—and a very clever insect—as well as the efforts of scientists in entomology, agroecology, parasitology, and epidemiology. Ethiopia is an ideal case for studying the historical human culture of illness, the dynamism of nature’s disease ecology, and its complexity within malaria.

Malaria kills millions of people each year and hundreds of millions more suffer chronic illness. Economic development is inhibited and poverty is perpetuated. Tren and Bate argue that action against malaria is over-centralised and narrowly focused, ignoring local conditions and concerns. Health agencies in developing countries and some companies are trying to stem a resurgent tide of malaria. Their work is, however, hampered by pressure from environmentalist groups and donor agencies which still crusade against the use of DDT and which have a partial victory under the POPs (persistent organic pollutants) convention. A continuing anti-DDT campaign would have as its victims people in some of the world's poorest countries.
