Evaluation of commercial aerosol insecticides for control of Aedes aegypti susceptible or resistant to pyrethroids.

Objective: To evaluate indoor use of commercial aerosols for dengue vector mosquito control, and estimate the number of treatable houses per can.

Materials And Methods: Four aerosol products containing combinations of pyrethroids (two containing propoxur and one containing synergists too), were evaluated with mosquitoes in a room of a Tapachulastyle house. Eight cages containing 20 insecticide susceptible or resistant females were hung from tripods, another set was placed in sheltered areas of the room.

Current enzyme-mediated insecticide resistance status of Aedes aegypti populations from a dengue-endemic city in southern Mexico.

Objective: To identify the enzyme-mediated insecticide resistance in Aedes aegypti in Tapachula, Mexico.

Materials And Methods: Biochemical assays were undertaken to determine the enzyme levels in mosquitoes from 22 sites collected in 2018 and 2020 in Tapachula. Results of 2018 were correlated with the resistance to insecticides pub-lished.

Objective: To determine the insecticide resistance status of Ae. aegypti and Ae. albopictus from Tapachula, México.
