Evaluation of Modified Autocidal Gravid Ovitraps for Control of Aedes Aegypti in St. Augustine, Florida.

Publication date: Mar 01, 2024

Aedes aegypti is an anthropophilic mosquito that vectors dengue, chikungunya, Zika, and yellow fever viruses. The US Center for Disease Control and Prevention (CDC)’s autocidal gravid ovitraps (AGOs) may facilitate the control of container-inhabiting Aedes mosquitoes and curb arbovirus outbreaks by taking advantage of oviposition-seeking behavior using pesticide-free technology. The AGOs, manufactured by SpringStar Inc. , were tested during the summer of 2018 in St. Augustine, FL. A total of 1,718 AGOs were deployed for study in 3 different 40-acre (∼18. 2 ha) plots at a density of 5-7 AGOs per house and a coverage of >90% for all AGO test sites. The AGOs were modified using tap water instead of infusion water to reduce the capture of nontarget organisms. Each intervention and reference area was monitored weekly using BioGents Sentinel traps and Sentinel AGOs. Generalized linear mixed models showed that changes to Aedes mosquito populations were more seasonal than treatment driven. Homeowners expressed positivity about traps and believed the traps were both effective and had directly contributed to increased quality of life.
