DETERMINING A DIAGNOSTIC DOSE OF PIRIMIPHOS-METHYL FOR AEDES AEGYPTI USING TREATED BOTTLES1.

There is a pressing need for innovative strategies to control arboviruses transmitted by Aedes aegypti. The modification of indoor residual spraying to target Ae. aegypti is one such strategy.

Insecticide resistance levels and associated mechanisms in three Aedes aegypti populations from Venezuela.

Background: The massive use of insecticides in public health has exerted selective pressure resulting in the development of resistance in Aedes aegypti to different insecticides in Venezuela. Between 2010 and 2020, the only insecticides available for vector control were the organophosphates (Ops) fenitrothion and temephos which were focally applied.

Objectives: To determine the state of insecticide resistance and to identify the possible biochemical and molecular mechanisms involved in three populations of Ae.
