Which statement defines vector incrimination?

• A. A test to determine insecticide susceptibility.
• B. A measure of mosquito population growth rate.
• C. The process of identifying and confirming which mosquito species are transmitting a pathogen in a given area; essential for targeting interventions.
• D. A method to estimate human biting rate using landing counts.

Answer: (C)

Vector incrimination is identifying and confirming which mosquito species are transmitting a pathogen in a specific area, so interventions can be targeted. It involves linking the presence of the pathogen to a particular mosquito species and showing that this species is capable of transmitting it under real-world conditions. This confirmation guides control efforts to focus on the actual vectors driving transmission rather than on all local mosquitoes. This is not about testing for insecticide susceptibility, which measures resistance to chemicals; nor is it about how quickly a mosquito population grows. It also isn’t a method for estimating how many humans are bitten by mosquitoes, which involves biting rate or landing counts. The value of vector incrimination lies in pinpointing the true vectors responsible for transmission to prioritize and tailor interventions effectively.
