Which of the following is not a part of a surveillance program for mosquito management?

A surveillance program for mosquito management is essential for understanding and controlling mosquito populations effectively. It typically involves various components that enable pest control professionals to gather data on mosquito presence and behavior.

Insect population mapping is crucial because it involves tracking where mosquitoes are located, which can inform intervention strategies. Weather monitoring is another vital component, as environmental conditions can significantly influence mosquito life cycles and activity levels. Larval source identification helps pinpoint where mosquito breeding occurs, directing efforts to eliminate or treat these breeding sites.

A crank-operated spreader, however, does not fit into a surveillance program framework. This equipment is typically used for applying pesticides rather than for gathering data on mosquito populations. Therefore, it is not part of the surveillance efforts aimed at understanding mosquito dynamics and guiding management actions.
