Abstract
Suspend® Polyzone® (deltamethrin) and Bifen
Insecticide/Termiticide (bifenthrin) were evaluated
in two eastern North Carolina neighborhoods from
May 18 – Oct 19, 2015 (23 weeks). Lots were sprayed
every 21 days. At 17 fixed locations (13 treatment,
four control), Centers for Disease Control and
Prevention (CDC) CO2-baited traps were deployed
overnight, once/week. Oviposition traps were also
deployed weekly and remained for seven days to
measure Aedes albopictus abundance. Mosquitoes were
identified to species and tabulated by location and
week. Adult and egg abundance was generally
significantly higher in control versus treatment traps.
The abundance of Psorophora columbiae and Ae. vexans
was significantly higher in control versus treatment
traps. Bifenthrin and deltamethrin showed
differences in efficacy (e.g. Ae. vexans, An. punctipennis,
and Ps. ferox abundance was higher in bifenthrin
traps compared to deltamethrin and control traps),
but this varied across neighborhoods and species.
