Methods of disease vector control

methods of disease vector control

Is any method to limit or eradicate the mammals, birds, insects or other arthropods (here collectively called "vectors") which transmit disease pathogens. The most frequent type of vector control is mosquito control using a variety of strategies. Several of the "neglected tropical diseases" are spread by such vectors.

Methods of Control

Vector control focuses on utilizing preventative methods to control or eliminate vector populations. Common preventative measures are:

Habitat/Environmental Control

Removing or reducing areas where vectors can easily breed can help limit population growth. For example, stagnant water removal, destruction of old tires and cans which serve as mosquito breeding environments and
good management of used water can reduce areas of excessive vector incidence.

Reducing Contact

Limiting exposure to insects or animals that are known disease. vectors can reduce infection risks significantly. For example, bed nets, window screens on homes, or protective clothing can help reduce the likelihood contact with vectors. To be effective this requires education and promotion of methods among the population to raise the awareness of vector threats.

Chemical Control

Insecticides, larvicides, rodenticides, Lethal ovitraps and repellents can be used to control vectors. For example,
larvicides can be used in mosquito breeding zones; insecticides can be applied to house walls or bed nets, and
use of personal repellents can reduce incidence of insect bites and thus infection. The use of pesticides for vector control is promoted by the
World Health Organization(WHO) and has proven to be highly effective.

Biological Control

The use of natural vector predators, such as bacterial toxins or botanical compounds, can help control vector
populations. Using fish that eat mosquito larvae or reducing breeding rates by introducing sterilized male tsetse flies have been shown to control vector populations and reduce infection risks
