Aerial Application Services for Effective Mosquito Management

Awareness of aerial application has increased this summer with the threat of Zika virus and an elevated risk of West Nile virus transmission throughout many parts of the country. Aerial applications can be an important component of an integrated mosquito management (IMM) program and are most often performed when the risk of vector-borne disease transmission is elevated. As municipalities and mosquito abatement districts gain a better understanding of the specific disease risks in their communities, our team continues to stay on the cutting edge of technology, utilizing fixed wing or rotary wing aircraft for each specific job to effectively target larval and adult mosquitoes.

eNews_aerial_applications_September_2016.jpgAs the owner of the largest fleet of aircraft in the world dedicated specifically to mosquito control, VDCI has been on the front lines combatting both West Nile Virus and Zika all summer. Each contract that we serve has unique needs and our team considers several factors before conducting an aerial application, including the species of the mosquito, the need for larval and/or adult mosquito control, the size and type of area to be treated, and whether the use of an airplane (fixed wing) or helicopter (rotary wing) is optimal.

VDCI is proud to have been working with the Sacramento-Yolo Mosquito and Vector Control District since 2005. We serve our partner with fixed wing aircraft that allow our teams to cover an extensive area that could be difficult to treat on the ground. Since the beginning of our partnership, our work there has expanded to surrounding counties. Today, VDCI supplies a dedicated fixed winged aircraft to Sac-Yolo and three additional contiguous counties of Placer, San Joaquin, and Stanislaus. In August, these counties began to see an increased presence of West Nile Virus in their mosquito populations and VDCI brought in additional aircraft to respond to the increased risk of disease transmission. In August alone, we treated 475,000 acres to control adult mosquito populations, which brought our total for the year to over 1.1 million acres in these California counties.

Fixed wing aircraft can provide benefits that include:

  • The ability to treat areas that can sometimes be difficult or too large to treat on the ground.
  • Breaking the mosquito breeding cycle after natural disasters where severe flooding occurs.
  • Providing quick results to emergency response situations where a disease outbreak is present.

On the opposite side of the country, VDCI is working to combat the spread of Zika virus via our rotary wing capabilities. Our work in Broward County, Florida focuses on the application of Bacillus thuringiensis israelensis (Bti). Bti is a naturally occurring soil bacteria used as a biological control agent for larvae stages of mosquitoes. There are important differences in the application of Bti versus that of products used to control adult mosquitoes. Although fixed wing aircraft can be used to apply Bti, a rotary wing aircraft can often be a better choice depending on the parameters of the mission. In this specific instance, the benefits of using rotary wing capabilities include:

  • More versatile landing and takeoff requirements. Helicopter loading zones are often closer to the spray blocks, decreasing ferry time, and increasing the actual application time.
  • Ability to target smaller areas. Helicopters can readily treat blocks as small as 10 acres, whereas airplanes need larger block sizes to be effective due to their speed and altitude.
  • Ability to make applications at slower flight speeds, along with the lower altitudes, allows a more precise application rate and deposition of product into the target zone.
  • The rotors of a helicopter can actually serve as a means to ‘push’ the product down into the spray zone.
  • Ability to turn quickly and maneuver within urban environments that contain many physical structures. This is extremely meaningful in combatting the primary vector of Zika virus, the Aedes aegypti.

As a result of the above, VDCI was able to target and treat 4 square miles where there was an increased risk of Zika virus transmission. The mission was completed in six hours when there were very few residents outside.

 

Aerial_Mosquito_Spraying_Two_Planes.jpgVDCI has been providing aerial application services for over 20 years. Due to the complicated nature of these applications, very few companies possess the experience and capability to handle aerial larval and adult mosquito control. Our expertise, our technology, and reporting capabilities, are an asset to any program in need of aerial application services.

VDCI is committed to public education and spreading awareness throughout the U.S. about the dangers of mosquito-borne diseases and their preventability, with the overarching goal of reducing illness and fatality statistics. Our dedicated and experienced staff works tirelessly to prevent the spread of mosquito-borne diseases in all of the contracts we service. If you would like more information about any aspect of an Integrated Mosquito Management (IMM) Plan, including mosquito surveillance, disease testing, or adult control, please contact Vector Disease Control International (VDCI) and we will help you get started immediately.
