Vector borne diseases: – Vector is defined as any living carrier that transports and infectious agent to ma susceptible individual (man). Transmission by vector may be mechanical or biological.
Infections agents are mechanically transported by crawling organism or flying insect through soiling of its feet or by passage of organisms through its gastrointestinal tract. In Biological transmission, disease causing agent passes through a development cycle. Malaria parasites in mosquitoes etc.
The vector borne disease can be controlled by eliminating the sectors and breeding grounds. Insecticides also applied to control the insect vector of diseases. In modern times control of pests of vectors is based on integration of environmental control, chemical control, biological control and genetic control.
The environmental control includes the elimination of breeding places, proper water management, and provision of piped water supply, adequate cleanliness and intensive education. Chemical control is made by use of mineral oils and synthetic incertitude. Biological control is made by use of carnivorous fish and mosquito control. Genetic control involves sterilization of male insects. There is need of the application of insect growth regulations.
