What does the dip procedure estimate in mosquito surveillance?

• A. Estimate of larval population in an area by number of larvae per dip
• B. Counts of adult mosquitoes per night
• C. Number of breeding sites per square kilometer
• D. Time to develop from egg to adult

Answer: (A)

The key idea is that the dip procedure is a larval sampling method. By taking a standardized dip and counting the number of larvae collected, you get an index of how many larvae are present in that aquatic habitat. This larval density helps infer potential adult mosquito production and guides control efforts. It isn’t used to count adult mosquitoes per night, nor to tally how many breeding sites exist in a given area, and it doesn’t measure how long it takes for eggs to develop into adults. The number of larvae per dip is the best way to estimate the larval population in the sampled area.
