A vector is an insect or animal that transmits a disease to other animals or humans.

Controlling mosquito vectors. WHO works with partners to provide education and improve awareness so that people know how to protect themselves and their communities from mosquitoes ticks bugs flies and other vectors. Creative mosquito control concept. LIMITATIONS OF VECTOR CONTROL METHODSInsect vector control efforts have been undertaken throughout the African continent and other tropical areas but long-term sustainable control has rarely been achievedInsect vector control efforts are invariably tied to the complex problems of ignorance poverty health politics and violence that have.

Insect growth regulators such as methroprene are specific to mosquitoes and can be applied in the same way as chemical insecticides. Mosquitoes as vectors of diseases. Insecticides larvicides rodenticides Lethal ovitraps and repellents can be used to control vectors.

To control these vector-borne diseases an integrated vector control program was implemented. Odorants can be used to control mosquitoes by repelling or by masking human odours or by attracting mosquitoes with lures into traps. Unfortunately no treatment in the form of vaccines or drugs is available for most of these diseases and vector control is still the main form of prevention.

Examples of common vectors include mosquitoes ticks mites and fleas. Hand drawn composition of mosquito biting a. The need to develop integrated strategies including both old and new methods of mosquito control is now widely accepted.

Even though semiochemicals alone might not be adequate as a control tool against mosquitoes using them in IVM programmes can provide a powerful tool that can help reduce and even eliminate vector populations. In Integrated Vector Management Graham Matthews covers the main chemical methods of vector control including the use of indoor residual spraying space treatments the use of treated bed nets and larviciding but also stresses the importance of drainage schemes and improvement of houses to prevent access of indoor vectors techniques that have largely been responsible for reducing the risk of vector borne diseases in Europe and the USA. Mosquitoes that transmit diseases are referred to as vectors and the diseases they transmit as vector-borne diseases.

Mosquito warning sign with flat design. The selective pressures associated with indoor chemical vector control interventions affect many biological characteristics of mosquito populations and mosquito traits that affect vectorial capacity and malaria transmission. Preventing or reducing dengue virus transmission depends entirely in controlling the mosquito vectors or interruption of humanvector contact.

Environmental management measures constitute an effective component of such strategies. It must be pointed out that the objective of environmental management for vector control. Find Download the most popular Mosquito Vectors on Freepik Free for commercial use High Quality Images Made for Creative Projects.

For example larvicides can be used in mosquito breeding zones. Mosquitoes represent the major arthropod vectors of human disease worldwide transmitting malaria lymphatic filariasis and arboviruses such as dengue virus and Zika virus. One promising class of new interventions under.

Heritable strategies for controlling insect vectors of disease Abstract Mosquito-borne diseases are causing a substantial burden of mortality morbidity and economic loss in many parts of the world despite current control efforts and new complementary approaches to controlling these diseases are needed. PDF On Mar 7 2016 Keith R. In essence a vector is a carrier of a disease.

Upward arrows denote an increase in the trait considered. IVM is defined as a rational decision-making process. Nevertheless due primarily to their high cost and often only moderate efficacy.

Part of our work is the surveillance monitoring and control of vectors that carry diseases such as West Nile virus and Lyme disease. Mosquito-borne diseases are causing a substantial burden of mortality morbidity and economic loss in many parts of the world despite current control efforts and new complementary approaches to controlling these diseases are needed. WHO promotes the strategic approach known as Integrated Vector Management IVM to control mosquito vectors including those of dengue.

Biological Control Potential biological control agents such as fungi eg Laegenidium giganteum or mermithid nematodes eg Romanomermis culicivorax parasitize and kill larval mosquitoes but they are not efficient for mosquito control and are not widely used. Heritable strategies for controlling insect vectors of disease. The main control strategy is focused on mosquito aquatic stages using diesel oil and Temephos.

Mosquitoes can transmit a number of human diseases including West Nile Zika dengue and encephalitis. Insecticides can be applied to house walls or bed nets and use of personal repellents can reduce incidence of insect bites and thus infection. Bacterial insecticides have been used for the control of nuisance and vector mosquitoes for more than two decades.

The main targeted mosquito vectors are Aedes aegypti and Anopheles arabiensis and in a lesser extent the potential arbovirus vector Culex pipiens sl. Hayes published Risk Assessment for Controlling Mosquito Vectors with Engineered Nucleases.
