Biological Control Of Mosquito Vectors

Past Present and Future. This is particularly important for the control of mosquito-borne arboviruses which normally do not have specific antiviral therapies available.

Biological control is the use of living organism to control a vector.

Biological control of mosquito vectors. Likewise mosquito fish including Gambusia affinis have largely been ineffective. Biological controls with predators of larval mosquito vectors have historically focused almost exclusively on insectivorous animals with few studies examining predatory plants as potential larvacidal agents. Biological control methods or strategies against the vectors are safe and environmental-friendly.

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. Using fish that eat mosquito larvae the use cat fish to eat up mosquito larve in pond can eradicate the mosquito population or reducing breeding rates by introducing sterilized male tsetse flies have been shown to control vector populations and reduce infection risks. A review of the role of ﬁsh as biological control agents of disease vector mosquitoes in mangrove forests.

Vector control is an essential component of mosquito-borne disease prevention and control in which targeting the mosquito vectors becomes the key control strategy against major mosquito- borne diseases. Mosquitoes are the vectors responsible for transmitting serious and life-threatening diseases such as malaria dengue yellow fever chikungunya and lymphatic filariasis. Biological Control of Mosquito Vectors.

Mosquitoes represent the major arthropod vectors of human disease worldwide transmitting malaria lymphatic ﬁlariasis and arboviruses such as dengue virus and Zika virus. Historically and today targeting mosquito vectors with primarily insecticide-based control strategies have been a key control strategy against major mosquito-borne diseases. The mosquitofish preys on mosquito larvae allowing us to keep mosquito populations under control.

Biological control is based on the introduction of organisms that prey upon parasitize compete with or otherwise reduce populations of the target species. There are several types of biocontrol including the direct introduction of parasites pathogens and predators to target mosquitoes. Mosquitoes represent the major arthropod vectors of human disease worldwide transmitting malaria lymphatic filariasis and arboviruses such as dengue virus and Zika virus.

Biological control The use of natural vector predators such as bacterial toxins or botanical compounds can help control vector populations. Mosquitoes as vectors of diseases Mosquitoes can transmit a number of human diseases including West Nile Zika dengue and encephalitis. Historically biological control utilizes predatory species and pathogenic microorganisms to reduce the population of mosquitoes as disease vectors.

Past Present and Future. Against Aedes a selection of larvivorous fish species and predatory copepods small freshwater crustaceans are effective against the immature larval stages of vector mosquitoes. Biological Control of Mosquito Vectors.

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. The primary biological control we use is the mosquitofish Gambusia affinis. Reducing human health risks while reducing environmental risk.

Very few effective vaccines or drugs have been developed so far to prevent or treat these diseases highlighting a need for vector control. Our integrated pest control methods also encourage natural mosquito control by discouraging growth of mosquito larvae while encouraging the survival and proliferation of natural mosquito predators. Mosquitoes that transmit diseases are referred to as vectors and the diseases they transmit as vector-borne diseases.

Microscopic observation of mosquito species which is the basis of morphological identification is a time-consuming and challenging process particularly owing to the different skills and. In addition the District is always looking for ways to improve our biological control program. Mosquito vector control methods The aim of vector control is to interrupt or eliminate local transmission of diseases reduce vulnerability to disease and prevent secondary infections from introduced diseases so they do not create further outbreaks.

Mosquitoes represent the major arthropod vectors of human disease worldwide transmitting malaria lymphatic filariasis and arboviruses such as dengue virus and Zika virus. However the success to date of such approaches is under threat from multiple insecticide resistance mechanisms while vector control VC options are still limited. Biological pest control or biocontrol is the use of the natural enemies of pests like mosquitoes to manage the pests populations.

Biological control methods are very important in protecting the public from mosquitoes.
