abstract：:The pheromone-mediated flight and landing behaviors of maleOstrinia nubilalis were studied in a wind tunnel. The pheromone source was placed in the middle of an 18 × 18-cm horizontal surface, and a smaller surface placed 4, 18, or 36 cm downwind. The smaller surface did not appear to affect significantly the flight tr...
