What are Delta traps used for?
The majority of delta traps are used for trapping and monitoring Lepidoptera. Delta traps can be used for adults up to about 25mm in length. Larger noctuids are more easily trapped in funnel traps (see our multipurpose funnel trap). The list on the back shows which traps are most suitable for which species. The small Delta trap is particularly used for the Pea moth (Cydia nigricana) for which a special kit is available, including trap, post, pheromones and instructions for interpretation. The pea moth kit is a spray decision tool.
