Which of the following is an effective technique in mosquito population monitoring?

Using larval surveys is an effective technique in mosquito population monitoring because it directly assesses the presence of mosquito larvae in their breeding environments, such as standing water. Monitoring larval populations provides crucial information about the life cycle stages of mosquitoes and can indicate potential outbreaks before they occur. By identifying the locations where larvae are present, control measures can be implemented more effectively, targeting the source of the population before they mature into adults.

This method is scientifically sound as it allows for early intervention and can help prioritize areas requiring mosquito control efforts. Larval surveys can provide quantitative data on the density and species of mosquito populations, enabling targeted action plans tailored to specific situations. Overall, focusing on the larval stage gives pest management professionals critical insights into managing mosquito populations effectively.
