For example larvicides can be used in mosquito breeding zones. And transforming the genome of the target mosquitoes and using cytoplasmic incompatibility as a.
Vector Control With A Focus On Aedes Aegypti And Aedes Albopictus Mosquitoes Literature Review And Analysis
Historically and today targeting mosquito vectors with primarily insecticide-based control strategies have been a key control strategy against major mosquito-borne diseases.
Mosquitoes vector control strategies. Vector control strategies Surveillance monitoring vectors Role of the entomologist Integrated vector management. Mosquito-control strategies Vector-control strategies in the last century were based on chemical agents such as dichloro-diphenyl-trichloroethane DDT. Mosquitoes primarily inside and to a lesser extent around houses as the primary vector control intervention for immediate response.
It also includes the appropriate vector controlstrategies for humanitarian emergency situations. Fixing the transgene in other cytoplasmic elements that are co-inherited with Wolbachia bacteria in the mosquito. It focuses on vectors that cause major problems inemergency situations mosquitoes non-biting flies rodents and fleas.
WHO promotes the strategic approach known as Integrated Vector Management IVM to control mosquito vectors including those of dengue. Appropriate vector control interventions for the response to the Zika virus outbreak include. Targeted residual spraying of resting sites of Aedes spp.
Preventing or reducing dengue virus transmission depends entirely in controlling the mosquito vectors or interruption of humanvector contact. There are three basic strategies for using Wolbachia to control vector populations. A primary strategy for arbovirus outbreak control such as dengue is the use of synthetic chemicals with quick-action killing of adult vectors using space spraying 2 5 6.
However the success to date of such approaches is under threat from multiple insecticide resistance mechanisms while vector control VC options are still limited. Insecticides larvicides rodenticides Lethal ovitraps and repellents can be used to control vectors. Readers interested in vectors thatcause less common problems are referred to additional sources of information.
University of Florida was found to be the leading patent filing entity and its patents were focused on suppression of vector population using techniques such as release of insects with dominant lethal RIDL and RNA interference RNAi. Other Vector Control Interventions Fogging area spraying using a machine mounted on the back of a truck. Either insecticide-treated nets ITNs or indoor residual spraying IRS.
Fogging or Area Spraying Fogging or ultra-low volume spraying or area spraying is primarily reserved for emergency situations such as epidemics. WHO currently recommends deployment of 1 of 2 core interventions for malaria vector control in areas at risk of malaria. Before a locally-acquired case s of chikungunya infection occurs professionals conduct surveillance to understand local populations of mosquitoes and begin control efforts.
Inserting the transgene directly into the Wolbachia genome and using cytoplasmic incompatibility mechanisms to suppress the target population and achieve the desired frequency in the target population. Vector control drug therapy Mosquito – Culex West Nile virus No Curative drug treatment available vector control Tsetse fly Glossina Sleeping sickness Vector control drug therapy. Although insecticides have been successfully used to control mosquitoes of the genera Aedes and Anopheles current ecological and environmental protection standards.
Vector control is a highly effective way to reduce malaria transmission and is a vital component of malaria control and elimination strategies. Improvement of water supply and water-storage systems. While diverse control strategies have been put in place for mosquito-borne diseases vector control continues to be a critical component in infection prevention.
Indoor residual spraying IRS and insecticide-treated nets ITNs are the 2 most important vector control measures that protect humans from the bite of malaria-carrying mosquitoes Global Regions. Biological larviciding control of mosquito larvae by introducing natural enemiespredators andor microbial agents applied in the air and on the ground. Further active and exciting areas of research on potential new tools for vector control include the development of targeted sugar baits which kill mosquitoes that are attracted to and feed on toxic sugar meals sprayed on plants or used in bait stations 46.
Vector control majorly focuses on the eradication of mosquitoes using a variety of chemical insecticides that includes organochlorides carbamates organophosphates and pyrethroids. Vector control strategy for mosquitoes proves to be efficient on Saba June 28 2020 Leave a comment A 2018 study of mosquito populations on the islands of Sint Maarten Saba and Sint Eustatius documented eleven different species including two new species for Sint Maarten a number of which are known to spread mosquito-borne diseases. IVM is defined as a rational decision-making process.
This is a preview of subscription content log in to check access. In the continental United States vector control professionals use integrated vector management strategies to control Aedes aegypti and Aedes albopictus mosquitoes. Chemical larviciding control of mosquito larvae using chemical larvicides applied in the air and on the ground.
Insecticides can be applied to house walls or bed nets and use of personal repellents can reduce incidence of insect bites and thus infection. Changes to human habitation or behaviour actions to reduce human vector contact such as installing mosquito screening on windows doors and other entry points and using mosquito nets while sleeping during daytime.
