Abstract:Catches of several species of Noctuidae and Arctiidae by 2 BL trap designs and their modifications were compared in field tests. BL lamps mounted above a 55-gal oil drum (barrel traps) were more effective than survey traps (BL lamps above a killing chamber) in catching male Trichoplusia ni (Hübner) and Heliothis zea (Boddie); an oil level 6 in. below the rim of the barrel proved to be the most practical. Increasing the number of lamps from 1 to 2 resulted in increased catches of female T. ni and Spodoptera exigua (Hübner), but the catches of T. ni males were not increased significantly. Covering of all but 1 in. of 1 lamp decreased catches of both sexes of T. ni. The use of bait, the synthetic T. ni sex pheromone, increased the catch of T. ni males in all trap types tested and tended to counteract the effect of the reduced light. Catch of T. ni males was not affected by changing the position of the bait from the top of the trap to the bottom of the baffles.
