Spring Larval Treatment
Aerial larva control of seasonally flooded woodlots is tentatively scheduled to begin each April. Fixed-wing aircraft treat approximately 52,000 acres of mosquito breeding habitat using granular Bacillus thuringiensis israelensis (Bti), Serotype 14 attached to ground corn cob, at the application rate of 2.5 to 3 pounds per acre. Bti is a biological larvicide that targets mosquito larvae. When the larvae ingest Bti, it causes them to die before they can develop into biting adult mosquitoes.
SCMAC employs two methods to ensure efficient and accurate aerial treatment. All aircraft use Global Positioning System (GPS) electronic guidance, which can be monitored in real-time by SCMAC staff. SCMAC utilizes Arc-GIS software to develop accurate treatment maps for both aerial and ground operations.
Seasonal vector control technicians begin larval control immediately following the completion of the spring aerial treatment. They concentrate on woodlots infeasible to treat by aircraft such as small woodlots less than 5 acres. Ground crews will use Bti or larviciding oil for this treatment depending on the mosquitoes’ stage of development.
September Special Larval Treatment – Saginaw County State Game Area
September Special Larval Treatment – Saginaw County State Game Area
To promote public health, we may conduct a special aerial larval treatment in portions of the Shiawassee River State Game Area in September.
This treatment would be in response to the annual managed flooding of the area to create waterfowl habitat. The resulting standing water can create suitable breeding habitat for mosquitoes.
Granular Bti will be applied by fixed-wing aircraft to the areas highlighted in yellow on the accompanying map.
The exact treatment date is determined by mosquito larval development, weather conditions, and the managed flooding activities.
