Koppert has added a plastic Deltatrap to its line of pheromone traps. The triangular pheromone trap uses luring substances to entice adult male insects into the trap where they get stuck on the adhesive plate making them easier to detect, identify and count. The long-lasting pheromone capsule is effective for six weeks and different pheromones are available. The plastic construction makes the trap less susceptible to adverse weather conditions when used outdoors.
