Abstract The objective of this study was to analyze O. rhinoceros attraction to the pheromone that was placed near and far from the light source. Samples were obtained using pheromone traps placed at a distance of ± 5 m (near) and ± 500 m (far) from the light source. Each village was installed with 10 pheromone traps, 5 traps were placed near the light source, and another 5 traps were far from the light source. Observation on O. rhinoceros imago captured was conducted for 12 weeks. The results showed that O. rhinoceros is more attracted to the pheromone traps placed near the light source. The sex ratio of male and female imago from traps placed both near and far from the light were 1:1.2 and 1:1.3, respectively. This study can provide information regarding O. rhinoceros monitoring using pheromone traps combined with the light to attract more O. rhinoceros imago.
