231 - Advancements for the SIT program for Aedes aegypti suppression in Lee County, FL.

Thursday, March 6, 2025
9:10 AM – 9:20 AM AST
Location: 208 B
Abstract: Lee County Mosquito Control District (LCMCD) concluded its successful pilot study to suppress populations of Aedes aegypti using the sterile insect technique (SIT) on Captiva Island, FL in September 2022. Since then, the focus of the SIT suppression efforts has shifted inland to Fort Myers, FL. Throughout 2023 surveillance was conducted to ascertain the entomological baseline. Additionally, several mark-release-recapture studies were performed in different seasons to estimate sterile male dispersal and the population of Ae. aegypti at various times over the year. LCMCD began releasing sterile male Ae. aegypti in Fort Myers in February 2024. Through consistent surveillance and continued sterile male releases, impacts to the wild population can be observed. LCMCD continues to scale up mass rearing Ae. aegypti and has conducted various experiments to support the increasing production, including ways to limit female contamination, observations of pupal stress tolerance, among others.
