What is the purpose of using traps in pest management?

Using traps in pest management serves a crucial function in monitoring pest populations and reducing their numbers. The primary aim of pest traps is to capture pests, which allows growers to assess the level of infestation within their greenhouse environment. By regularly monitoring these traps, one can identify pest activity trends over time, informing decisions about whether control measures need to be employed.

Moreover, many traps are designed to not only monitor but also actively reduce pest populations. For example, traps may use attractants that lure pests in and prevent them from reproducing, effectively managing the population within the greenhouse. By integrating trapping with other pest control methods, greenhouse managers can develop a more comprehensive pest management strategy that minimizes damage to plants while promoting a healthier growing environment. This approach aligns perfectly with integrated pest management techniques, which prioritize long-term solutions over the immediate application of pesticides.

The other options suggest purposes that do not align with responsible and effective pest management strategies. Attracting pests or increasing their population would counteract the goal of protecting plants, and preventing plants from growing is not a desired outcome in greenhouse management.
