Who determines the effectiveness of aerial spraying of pesticides to control vectors?

• A. Public Health
• B. Bioenvironmental Engineering
• C. Base Civil Engineering
• D. Aerospace Medicine Council

Answer: (A)

The main idea here is that determining whether aerial spraying reduces disease risk and vector populations is a public health evaluation task. Public health teams oversee vector control programs, collect and analyze surveillance data, and set metrics to judge success. They track changes in how many vectors are present, their distribution, and whether disease indicators decline after spraying. They also account for spray coverage, timing, environmental factors, and insecticide performance, using pre- and post-spray data to decide if objectives were met or if adjustments are needed. While other roles may support the operation—engineering aspects of the spray system or base infrastructure—the authority to interpret effectiveness rests with Public Health because it centers on population health outcomes and risk reduction.
