Pheromonal trapping methods for lesser grain borer, Rhyzopertha dominica (Coleoptera: Bostrichidae)
Environmental Entomology 16 (3), 747-751
Abstract: In bagged grain, probe traps baited with 50 µl of dominicalure 1 released from rubber bands were attractive to lesser grain borer, Rhyzopertha dominica (F.). For aerial trapping, dominicalure was a powerful attractant both inside a warehouse and outdoors. Dominicalure 1, dominicalure 2, and mixtures were equally attractive. On average, pheromone traps captured 8- and 152-fold more insects than check traps inside the warehouse and outdoors, respectively. The Lindgren funnel trap had a significantly greater capture than six other designs tested. Of four dispenser types tested, the 0.4-ml polyethylene test tube retained activity longest, up to 30 d under summer conditions. Best aerial trap placement was along walls close to the ground. Trap catch increased with increasing pheromone release rate.
