Chemical larval control can only be done by ground application targeting previously mapped breeding sites. Vector control involves using preventive methods to eradicate or control vector populations, in order to limit the transmission and spread of diseases. Fish species such as Gambusia spp. In general adult mosquito control operations are aimed at the prompt reduction of adult mosquito density and longevity in a defined area in case of an outbreak. Several formulations of microbial larvicides based on Bacillus thuringiensis israelensis are available on the EU market (liquid, powder, granular, briquette) [86]. A number of traps have been developed to attract, catch and kill large numbers of mosquitoes, thus removing them from the target area. These compounds have good safety margins in terms of acute toxicity for warm blooded animals but are toxic for non target insect species and aquatic organisms [87–90].

The extrapolation of information produced in North America to Europe might be limited because of the seemingly lower level of WNV transmission in the European region probably due to the long-time exposure of wild bird populations resulting in an ecosystem that is less suitable for large outbreaks.

Moreover, the information necessary to make a robust cost-benefit analysis that guides the implementation of the appropriate measures is largely missing, as well as the species-specific WNV vector density thresholds, and the fact that mosquito control programs mostly rely on empirical data and past experience.

There are four primary types of motor control methods for induction motors connected to VFDs: V/f (volts-per-hertz), V/f with encoder, open-loop vector, and closed-loop vector. Integrated vector control that includes a multipronged approach such as indoor residual spraying, destruction of vector breeding sites, and reducing human/vector contact through methods such as insecticide-treated nets (ITNs) is advocated. J Vector Ecol. A cost-effectiveness analysis of vector control generically starts from a problem and presuppose an analysis of costs and effectiveness of each alternative solution [103]. This approach must be carefully evaluated in terms of environmental risk and the possible negative impact on biodiversity.

Adult control is considered the most convenient vector control approach during the outbreak phase because it has the capacity to promptly reduce infective mosquito females responsible for vectoring the disease as well as to reduce the mean longevity and the total reproduction capacity of local vector populations.

Effective surveillance must be maintained during vector control activities to determine if and when re-treatment is required to maintain suppression of the vector populations. The high number of non-symptomatic cases may increase the risk of WNV transmission through blood donation or organ transplants. CAS Control strategiesmay be classified as follows:⢠environmental control: alter breeding sites by draining or filling sites, regular disposal of refuse, maintain clean shelters, and personal hygiene.⢠mechanical control: use screens or bednets, traps, food covers, lids or polystyrene beads in latrines⢠biological management: use living organisms or products against vector larvae, such as fish that eat ⦠Hurst T, Ryan P, Brown M, Kay B: Fushing for a mosquito control agent. Therefore, there is an urgent need to analyse the European experiences of the prevention and control of outbreaks of West Nile virus infection and to perform robust cost-benefit analysis that can guide the implementation of the appropriate control measures. Further studies are needed in the EU to assess the value of each method to prevent and control outbreaks of WNV infection and to assess the best use in time and space (e.g. 1956, 5 (4): 579-620.
