Gainesville is the largest city in the region of North Central Florida and the home of
the University of Florida as well as the Santa Fe College. The University of Florida is ranked as
the nation's ninth largest university with 51,725 enrollment, plus a total of 15,887 students at the
Santa Fe College, making Gainesville home to a significant transient population and one that
frequently travels to arbovirus endemic areas abroad. Thus, Gainesville is at great risk of
introduction and outbreak of dengue, chikungunya and Zika viruses.
The Gainesville Mosquito Control program (GMC) is a city funded mosquito control
program that provides mosquito control services for the citizens of Gainesville. Even though
GMC is not a State-approved mosquito control program, it carries the same duties as other
mosquito control programs: To protect Floridians health and safety and foster the quality of life
from pestiferous and disease-carrying mosquitoes without the State funding. GMC uses
Integrated Mosquito Management (IMM) approach - a combination of breeding site reduction,
biological, chemical and physical control methods and citizen education to maintain targeted
species of mosquitoes at acceptable levels. GMC performs regularly scheduled inspections
(with treatment if warranted) in over 450 identified mosquito breeding sites, monitors mosquito
populations by using CDC light traps to gauge daily mosquito control operations, provides
mosquito fish to meet the needs of citizens, and conducts larval control by applying larvicides.
GMC also uses ground-level, ultra-low volume (ULV) fogging when large numbers of adult
mosquitoes are present in our area, and when source reduction or biological control or
larviciding is inadequate. All of GMC employees are licensed with Public Health Pest Control
(PHPC) licenses.
Alachua County has had four confirmed travel-related cases of Zika infection and more
than 31 suspected cases so far. With more than 50% of the county population living within the
city of Gainesville, GMC plays a key role in terms of fighting for the Zika infections in Alachua
County. So far GMC has, at the request and in coordination with the Department of Health
(DOH)-Alachua, investigated and responded to a number of suspected and confirmed cases of
Zika infection with limited resources. Furthermore, as mosquito season is under the way,
mosquito control staff will be more focused on routine mosquito control operations such as
responding to citizen’s service requests and conducting larvicide and adulticide missions. GMC

is in urgent need for extra funding to hire additional personnel to ensure adequate response
during the upcoming mosquito season.
GMC’s CDC light trap collection indicates that Aedes albopictus is the only container
mosquito species in Gainesville. However, the re-emerging of Aedes aegypti in St. Johns and
Duval Counties is a wakeup call for us. GMC is planning to enhance our surveillance program
by adding BG sentinel traps into our routine trapping system so that the detailed distribution of
Ae. albopictus and Ae. aegypti in the County level can be determined. Aedes albopictus hot
spots will be identified. Currently GMC has 4 BG traps being used for Zika case response. We
want to employ additional BG traps into our 16 trapping zones. GMC is also planning to expand
our ovitrap program from current 2 locations to 16 locations/zones (GMC started monitoring Ae.
albopictus population by using ovitraps last year, we successfully detected the seasonality of
oviposition and egg hatching rate of Ae. albopictus in Gainesville). The results were reported at
“The 13th Anastacia Mosquito Control District’s (AMCD) Workshop” (Please the attached
AMCD2016 PowerPoint presentation).
Last year, GMC conducted a field study to evaluate the efficacy of ULV truck spray
against caged Ae. aegypti. Results indicated that ground ULV spray had poor control of this
species; the average mortality ranged from 2 to 45% 24-hour post treatment (Please see the
attached AMCA.Jiang presentation). However, in a separate study, an excellent control was
yielded by using backpack sprayer to treat the natural population of adult Ae. albopictus. Also,
the number of eggs was reduced significantly (Please see the attached Duet presentation at the
Florida Mosquito Control Association (FMCA)). GMC decided to incorporate this control strategy
into our Zika emergency response plan and to expand this study by testing different adulticides
and backpacks. Because backpack control lasts only for 1-3 days, GMC wants to incorporate
larval control strategy by adding thermal fogger application to achieve a long term control of Ae.
albopictus; as reported by Dr. James Cilek, Navy Entomology Center of Excellence.
Detailed budget for the emergency response for Zika:
Personnel: Two full time equivalent temporary positions. These positions will be responsible for
the BG and ovitraps setup, retrieving, data collection. The two also are in charge of field larval
collection as well as bring the eggs and larvae back to the lab to rear to adult for ID. The two are
required to conduct public education and outreach regularly, door to door inspection and clean
up in the case of Zika cases.
Equipment:
IGEBA TF-34 Thermal fogger: Larvicide application
10 BG traps, batteries and chargers: Aedes albopictus and Ae. aegypti surveillance
Eaton Brother green fluted plastic vases: ovitraps
Germination paper: Used to collect Aedes egg in the field
HOBO water proof shuttle thermometers: Will be used to record field weather data
Curtis Dyna-Fog Twister XL3: Backpack sprayer for adulticide application
IPad: will be used for field data collection
Chemicals:
Vectobac WDG: Larvicide for thermal fogger application
Naturlar DT: Larvicide for small container control
Duet: Adulticide
Miscellaneous:
Lab supplies, computer supplies, bottles, BG lures, dry ice

Inform local mosquito control officials of suspect cases Inform Arbovirus Surveillance Coordinator on
suspicion of locally acquired cases Provide public information on disease, transmission,
prevention, protective actions
Mosquito Bite Prevention
17
DRAIN water from any containers where water has collected.
CLOTHING: If you must be outside when mosquitoes are active, cover up. Wear shoes, socks, long pants, and long sleeves.
REPELLENT: Apply mosquito repellent to bare skin and clothing. Always use repellents according to the label. Repellents with DEET, picaridin, oil of lemon eucalyptus, para-menthane-diol, and IR3535 are effective. Use netting to protect children younger than 2 months.
