Studies were conducted in an asparagus field in taigu (37°18'N, 112°29'E, 824 m above sea level), Shanxi province, China, May to June, 2009 to 2011, to evaluate the influence of interval distance and orientation on catches of the carpenterworm, Isoceras sibirica Alpheraky (Lepidoptera: Cossidae) in pheromone-baited traps. The results showed that catches of male I. sibirica moths in upwind were higher than in other traps for any intertrap distances. When intertrap distances were shorter than 30 m, interference between traps occurred. These results reveal the effective trap orientation and interval distance for I. sibirica and thus provide guidelines for improving the effectiveness of traps in monitoring and controlling I. sibirica in fields.
