In Panama City Beach (Bay County, FL), WNV transmission is monitored using sentinel chickens and testing mosquito pools for presence of viral RNA. In the current work, we monitored WNV transmission from 2014 to 2020 through weekly serology sampling of sentinel chickens; mosquito populations through biweekly mosquito collections by suction traps (1 m and 9 m) and weekly gravid trap collections; and mosquito infection rates using a reverse transcriptase-polymerase chain reaction (RT-PCR) assay. Samples were sent to the Bureau of Public Health Laboratories (Tampa, FL) for testing presence/absence of WNV via RT-PCR assay. Our results indicated that canopy surveillance could augment ground collections, providing greater proportions of Culex mosquitoes with less bycatch compared with ground collections. Serology indicated 94 seroconversions to WNV in the study area from 2014 to 2020. The most active year was 2016, which accounted for 32% (n = 30) of all seroconversions reported during the study period. We detected 20 WNV-positive mosquito pools from Culex quinquefasciatus during 2014-17; mosquito infection rates ranged from 2.02 to 23.81 per thousand (95% CI). Climate data indicated anomalously high precipitation in 2014-19 preceding WNV transmission. Data analyzed herein indicate utility in year-round continuous and diversified surveillance methodologies.

Unfortunately, when the Ae. albopictus colony was initially started in 2003 from a field collection in Gainesville, FL, susceptibility to insecticides was not determined. Since that time, this species has been in constant production without exposure to pesticides by the Center for Medical, Agricultural, and Veterinary Entomology, Gainesville, FL. In order to determine its susceptibility level to malathion and compare it with 3 current field-collected Ae. albopictus populations, 3 organophosphates (malathion, chlorpyrifos, naled) and 2 pyrethroids (permethrin, deltamethrin) were tested in the laboratory, using the Centers for Disease Control and Prevention bottle bioassays. Results of the study confirmed that the USDA-Gainesville Ae. albopictus was still highly resistant to malathion even after being maintained in the laboratory for 16 years without exposure to pesticides. The 3 field-collected populations were also resistant to malathion but slightly less so than the USDA-Gainesville population. Rotation of pyrethroid products 16 years ago did not result in any significant reduction of malathion resistance in the field populations. Neither the USDA-Gainesville nor the field-collected Ae. albopictus populations showed cross-resistance to chlorpyrifos and naled.

The goals of this study were to determine the level of susceptibility and insecticide resistance mechanisms in the Ae. aegypti population. Temephos susceptibility in larvae was evaluated with bioassays using the World Health Organization's methodology, and susceptibility of adult mosquitoes was determined by the impregnated bottle bioassay, recommended by the Centers for Disease Control and Prevention. Resistance mechanisms were determined with biochemical assays. Mosquito larvae from the Havana Zoo were found resistant to temephos, which was associated with the activity of the enzymes α- and β-esterases and mixed function oxidases but not glutathione-S-transferase. Adult mosquitoes were susceptible to pyrethroid (lambda-cyhalothrin, deltamethrin, and cypermethrin), organophosphate (chlorpyrifos), and carbamate (bendiocarb).
