Insecticide resistance status of Aedes mosquito vector in India: A review

Abstract

In India, Aedes mosquitoes are well prevalent and play a key role in the transmission of vector borne diseases. Vector management is principally carried out by using various chemical insecticides since long, but consistent use has led to developing insecticide resistance which restricts the effectiveness of the control strategy. This review highlights the pieces of evidence on developing resistance level to major classes of chemical insecticides such as carbamates, organochlorines, organophosphates and pyrethroids with mechanisms of developed resistance in various regions of India. Insecticide resistant mechanisms which altered susceptibilities to insecticides can be categorized into two major groups as target site sensitivity and metabolic detoxification. Among different provinces of India, maximum level of resistance was observed against organochlorines (72%) followed by organophosphates (28%), pyrethroids (28%) and carbamates (16%). A summarized data on insecticide resistance status from all over India will be helpful to improve resistance management and epidemic disease control.
