What does a Landing Rate Count measure?

• A. Count mosquito landings on body in 1-5 mins
• B. Number of eggs laid by females
• C. Number of mosquitoes captured in traps
• D. Number of bites per person per hour

Answer: (A)

Landing Rate Count measures how often mosquitoes land on a person during a short observation period. This directly reflects host-seeking activity and the immediate risk of contact with mosquitoes, since each landing indicates an opportunity for a bite if contact isn’t repelled. The typical approach has an observer count landings on exposed skin over a defined window, often 1–5 minutes. It is not about eggs laid, traps, or bites counted per hour, which are different metrics. This method gives a quick, field-friendly sense of biting pressure at a site or time and helps evaluate factors like repellents or spatial interventions. Keep in mind it can be influenced by observer accuracy, clothing, repellents, time of day, and species-specific behavior.
