A SURVEY ON MOSQUITO VECTORS OF DISEASES

CHAPTER ONE

INTRODUCTION

Background of the study

Mosquito-Borne Diseases or mosquito-borne illness is disease caused by bacterial, viruses, parasites transmitted by Mosquitoes. This can transmit disease without being affected themselves. Mosquitoes play essential role in the transmission of animal diseases. Mosquitoesborne diseases involve the transmission of viruses and parasites from animal to animal, animal to person or person to person without affecting the insect vectors with symptoms of disease. It is a main leading problem to human kind. Some mosquitoes are vectors for some of the diseases. Typically the diseases are caused by viruses or tiny parasites

Mosquitoes are now called ‘public enemy no.1’ by the world health organization. There are more than 4500 species of mosquitoes distributed throughout the world under 34 genera, but mostly belongs to Aedes, Anopheles and Culex. They are visitors of several public and life threatening disease including protozoan’s (Malaria), Viral (Yellow fever, Dengue fever, Chikungunya, West Nile virus, Japans encephalitis) or Pelmentic (filariasis) infections. These diseases not only cause mortality or morbidity among the humans and cause social, cultural environmental and economic loss of the society.

The Mosquito Borne Diseases (MBD’S) of public health importance are complex and their occurrence depends on the interaction of various biological, ecological, social and economic factors. Though several measures for their prevention and control are followed, yet the problem density is too high with 300–500 million cases and 1.1–2.7 million deaths due to malaria alone globally per year. While there are many methods of mosquito control, experts now recommend an “integrated approach” that is, an approach which avoids the excessive use of any one method but tries to combine one or more methods with a view to obtain maximum results with minimum inputs and also to prevent environmental pollution with toxic chemicals and development of insecticide resistance.

Statement of the problem
