Which of the following is a common method for controlling mosquito populations?

Implementing larviciding and adulticiding as needed is an effective method for controlling mosquito populations because it addresses mosquitoes at different life stages. Larviciding targets the immature stages (larvae), which live in water, while adulticiding aims to control the adult mosquito population that is responsible for biting and transmitting diseases. This integrated approach enhances the overall effectiveness of mosquito control programs.

Using pesticides only during the winter would not be effective, as mosquitoes are typically less active during cold months and do not breed in winter conditions. Only trapping adult mosquitoes does not effectively reduce populations across all life stages; while it may capture some adults, it does not prevent subsequent generations. Relying solely on natural predators, such as birds or other insects, may also be insufficient, as natural predation can be influenced by environmental factors and may not keep mosquito numbers low enough to prevent public health threats. Thus, a combination of larviciding and adulticiding ensures a more comprehensive and proactive strategy for managing mosquito populations.
