Abstract

Efficiencies of light and pheromone traps were estimated from captures of moths emerging from pupae in the center of circular arrays of traps up to 200 m in radius. Light traps captured 1 insect for every 3.6 that passed through a linear meter at the trap, an efficiency factor of 0.28. This factor was constant for different insect densities. The pheromone traps were 3.5 times as efficient as light traps based on the captures of males only. The low efficiencies imply that the traps have a small zone of influence and several may be needed in a limited area to produce catches within reasonable confidence limits when populations are sparse and detection of increasing numbers has the greatest value.
