Insecticide resistance and vector control.
نویسندگان
چکیده
Insecticide resistance has been a problem in all insect groups that serve as vectors of emerging diseases. Although mechanisms by which insecticides become less effective are similar across all vector taxa, each resistance problem is potentially unique and may involve a complex pattern of resistance foci. The main defense against resistance is close surveillance of the susceptibility of vector populations. We describe the mechanisms of insecticide resistance, as well as specific instances of resistance emergence worldwide, and discuss prospects for resistance management and priorities for detection and surveillance.

<Anopheles culicifacies is a main malaria vector in southeastern part of Iran, bordring Afghanistan and Pakistan. So far, resistance to DDT, dieldrin, malathion and partial tolerance to pyrethroids has been reported in An. stephensi, but nothing confirmed on resistance status of An. culicifacies in Iran. Methods: In current study, along with WHO routine susceptibility test with DDT (4%), di...

Background: The German cockroach (Blatella germanica) is one of the most important vectors of public health interest due to its involvement in the transmission of infectious diseases. Different insecticides are used to control cockroaches; however, resistance developed against most of insecticides has made them ineffective. Attempts should always be made to find proper alternat...
متن کاملInsecticide Control of Vector-Borne Diseases: When Is Insecticide Resistance a Problem?
Many of the most dangerous human diseases are transmitted by insect vectors. After decades of repeated insecticide use, all of these vector species have demonstrated the capacity to evolve resistance to insecticides. Insecticide resistance is generally considered to undermine control of vector-transmitted diseases because it increases the number of vectors that survive the insecticide treatment...

Glutathione S-transferases (GSTs) are a major family of detoxification enzymes which possess a wide range of substrate specificities. Interest in insect GSTs has primarily focused on their role in insecticide resistance. In this study, following World Health Organization (WHO) routine susceptibility test, DNA was extracted from specimens of Anopheles stephensi collected from the Kazeroon distri...
متن کاملMalaria Vector Surveillance and Insecticide Resistance Monitoring and Management
As global efforts to control and eliminate malaria intensify, vector control interventions are being extensively deployed in the context of the World Health Organization (WHO)-led integrated vector management (IVM) strategy [1]. Indoor residual spraying (IRS) and insecticide treated nets (ITNs), supplemented by focalized larval source management, have been harnessed for interrupting transmissio...

In the past decade, there has been rapid scale-up of insecticide-based malaria vector con‐ trol in the context of integrated vector management (IVM). But, the continued efficacy of vector control interventions is threatened by the selection of insecticide resistance. Evi‐ dence of insecticide resistance operationally undermining malaria vector control pro‐ grammes is invariably mounting and is ...
