Insecticides susceptibility status of dengue vector, Aedes aegypti in NCR Delhi, India

Abstract

Aedes aegypti plays a key role in dengue transmission, as a principal vector. The vector species have progressively started to developed resistance against most of the currently used insecticides. Hence, a study was carried out in dengue endemic areas of NCR during 2018 to find out the current situation of insecticide susceptibility status of Aedes aegypti against various insecticides under ambient room temperature of 28 2 0C and relative humidity at 70 5%. The results revealed that adult Ae. aegypti was resistant to DDT, tolerant to Malathion and susceptible to Deltamethrin. However, the larvae were found to be susceptible to Temephos and Diflubenzuron.
