Book Description
Vector-borne diseases are a major health problem in South-East Asia and in other parts of the world. There are about 4,500 mosquito species in existence; species belonging to the Anopheles genus transmit malaria. Combating malaria is part of the Millennium Development Goals, and vector control is a key strategy both regionally and globally. Therefore, the review and dissemination of information on vector species is critically important. Most of the anophelines that are involved in the transmission of malaria in South and South-East Asia have been identified as species complexes. Members of a species complex are reproductively isolated evolutionary units with distinct gene pools and hence they differ in their biological characteristics. In 1998 WHO published Anopheline Species Complexes in South-East Asia. New identification tools have been developed since then, and therefore this updated edition was needed. It summarizes work that has been done on anopheline cryptic species and will be highly valuable to researchers, field entomologists and malaria-control program managers.

Book Description
Taxonomy is fundamental to understanding the variety of life forms, and exciting expansions in molecular biology are re- volutionising the obtained data. This volume reviews the ma- jor molecular biological techniques that are applied in ta- xonomy. The chapters are arranged in three main sections:1) Overviews of important topics in molecular taxonomy; 2) Case studies of the successful application of molecular methods to taxonomic and evolutionary questions; 3) Protocols for a range of generally applicable methods. The described techni- ques include DNA-DNA hybridization, DNA fingerprinting, RFLP analysis, and PCR sequencing.

Book Description
The definitive reference on the biology, evolution, ecology, and diversity of all known species of the world's mosquitoes. Critical for entomologists, public health professionals, and epidemiologists across the world. Biting multiple times on two, three, or more different hosts, it is no surprise that some species of mosquitoes have co-evolved with pathogens. For humans and other animals, the result has been some of the most challenging diseases known. It has been said that Anopheles gambiae, as the primary transmitter of malaria parasites to humans, is the most dangerous animal in the world. Certainly malaria has killed more people than all the wars that ever took place. Even now, despite drugs and mosquito control, malaria claims the lives of 405,000 per year. The vast majority of mosquito species are not involved in pathogen transmission to humans, but those that are make a huge impact on global health. In this two-volume set, three of the world's leading experts on mosquito disease, ecology, and systematics offer readers unique insights into the fascinating world of mosquitoes while illustrating their diagnostic morphological features in detail. Comprehensively addressing the natural diversity of mosquitoes, the book explains their life histories, bionomic traits, and the physiological and physical adaptations they evolved in response to ever-changing environmental conditions. Mosquitoes are one of the best-known groups of insects, making this book a great starting place for anyone who would like to understand entomology by knowing the details about a representative family. Volume One contains a review of the biology and diversity of mosquitoes. Biology is treated in the following chapters: • Evolution • Nomenclature • Distribution • Development • Dormancy • Mosquito Movement • Feeding and Nutrition • Excretion • Copulation and Insemination • Egg Development and Oviposition The chapters on biology are followed by a well-illustrated summary of the characteristics of all 41 genera and of representative species of mosquitoes. This treatment of the morphological diversity of mosquitoes is accompanied by a glossary of all morphological terms used. Volume Two features • a long-awaited comprehensive mosquito taxonomic catalog detailing the current taxonomic and systematic status of all 3,698 valid species and subspecies, 41 genera, and 187 subgenera • a list of all taxa for definitive use of nomenclature • complete lists of species synonyms, distributions, key taxonomic works, and newly defined informal names • origins of scientific names Readers will discover that some mosquitoes undertake courtship rituals, while others guard their eggs, feed solely on earthworms, or can survive as immatures under ice sheets or in salt-encrusted pools. Hundreds of drawings and high-resolution, close-up images illustrate the text. The most complete reference work on mosquitoes ever produced, Mosquitoes of the World is an unmatched resource for entomologists, public health professionals, epidemiologists, and reference libraries.

Book Description
Towards Malaria Elimination - A Leap Forward was started to mark the occasion for renewed commitment to end malaria transmission for good (the WHO's call for "Malaria Free World" by 2030). This book is dedicated for the benefit of researchers, scientists, program and policy managers, students and anyone interested in malaria and other mosquito-borne diseases with the goal of sharing recent information on success stories, innovative control approaches and challenges in different regions of the world. Some main issues that emerged included multidrug-resistant malaria and pandemic risk, vaccines, cross-border malaria, asymptomatic parasite reservoir, the threat of Plasmodium vivax and Plasmodium knowlesi, insecticide resistance in Anopheles vectors and outdoor malaria transmission. This book is one little step forward to bring together in 17 chapters the experiences of malaria-expert researchers from five continents to present updated information on disease epidemiology and control at the national/regional level, highlighting the constraints, challenges, accomplishments and prospects of malaria elimination.

Book Description
Genetic Control of Malaria and Dengue focuses on the knowledge, technology, regulation and ethics of using genetically modified mosquitoes to interrupt the transmission of important vector-borne diseases including Malaria. It contains coverage of the current state of knowledge of vector-borne diseases and how they are currently controlled; vaccine, drug and insecticide development; various strategies for altering the genome of mosquitoes in beneficial ways; and the regulatory, ethical and social environment concerning these strategies. For more than five decades, the prospect of using genetically-modified mosquitoes to control vector-borne disease transmission has been a purely hypothetical scenario. We simply did not have the technology or basic knowledge to be able to do it. With the explosion of field trials and potential interventions in development, Genetic Control of Malaria and Dengue provides a comprehensive overview of research in genetics, microbiology, virology, and ecology involved in the development and implementation of genetic modification programs for virus and disease control. This book is meant to provide a practical guide to researchers, regulators and the general public about how this technology actually works, how it can be improved, and what is still unknown. - Includes coverage of vectorial capacity, critical to understanding vector-borne disease transmission - Provides a summary of the concepts of both population suppression and population replacement - Contains pivotal coverage of ethical and ecological ramifications of genetics-based control strategies

Book Description
Admittedly, the world and the nature of forced migration have changed a great deal over the last two decades. The relevance of data accumulated during that time period can now be called into question. The roundtable and the Program on Forced Migration at the Mailman School of Public Health of Columbia University have commissioned a series of epidemiological reviews on priority public health problems for forced migrants that will update the state of knowledge. Malaria Control During Mass Population Movements and Natural Disasters- the first in the series, provides a basic overview of the state of knowledge of epidemiology of malaria and public health interventions and practices for controlling the disease in situations involving forced migration and conflict.

Book Description
One million dead a Wear, 500 million with the disease, 2.5 billion people at risk : this is the malaria balance sheet in 2007. The distribution and seriousness of the disease depend on the pathogens and vectors involved, as welt as environmental conditions. Of the four parasites (Plasmodium), only P. falciparum kilts although the other three cause debilitating disease with regular relapses and recrudescence. More than fifty species of Anopheles can fulfil the vector rote which is essential in transmission of the parasite between human beings. Climatic factors (temperature and rainfall), the environment and biogeographical particularities dictate the distribution of anopheline species and determine transmission rates. This is why it makes sense to tank about the biodiversity of malaria. Today, more than 90% of deaths from malaria occur in Tropical Africa which is home to only 10% of humanity. Every 30 seconds a child dies from malaria. This continent harbours the most effective vectors (An. gambiae and An. funestus, in particular) and the climate is highly conducive to transmission of the disease. Severe malaria is also seen in forest foci in Southeast Asia, Papua-New Guinea and the Amazon. In the rest of the tropical and subtropical world, P. vivax and/or P malariae cause less severe disease.
