Pan trap
A pan trap is a type of insect trap used to sample the abundance and diversity of insects, primarily used to capture small Hymenoptera. Pan traps are typically constructed with a bowl with shallow sides filled with water and soap or a preservative and killing agent. Yellow is the most commonly used color, but other colors including blue, white, and red are used to target different insect species. Pan traps are an efficient, cost effective and simple to use trap when targeting Hymenoptera or similar pollinators
