The Wing Trap is designed to allow adjustment to maximize trap performance for the behavioral patterns of different insects. The trap can be used with short spacer bars between top and bottom to allow full plume flow from all trap sides for most trapping programs. For insect pests such as the red-banded leafroller and codling moth, the spacer bars can be omitted, and the bottom end folded down to deflect the pheromone plume downward. The Wing Trap has a replaceable, sticky paperboard bottom with a grid pattern to aid in counting the trapped insects. It can be changed as needed when it becomes filled with insects or dirt. This is an ideal trap for general monitoring programs—much data is available using this style trap for monitoring vegetable, fruit, and nut crops as well as for stored products.
