Oryctes agamemnon arabicus (Fairmaire) (Coleoptera: Scarabaeidae) is a date palm insect pest that causes damage to trunk and roots and can damage grass lawns in the United Arab Emirates (UAE) and other countries such as Oman, Saudi Arabia, and Tunisia. The goal of this study was to monitor population dynamics and to evaluate six light colors (white, green, red, yellow, blue, and infrared) and two lamp types (mercury and energy-saving) in light traps. Experiments were performed on a date palm farm during a 2 yr period (2010 and 2011). It was found that this insect is a univoltine pest with a single population peak. Adults appeared in the field around middle of April and early May and the population continued to build until maximum numbers were reached in mid June. No adults were found after the end of September. Photoperiod showed a significant correlation with the changes in adult population size. White light emitted from mercury lamps attracted significantly more O. agamemnon arabicus adults compared with the other tested light colors. Increasing the wattage of mercury lamps from 160 to 250 watt did not significantly increase the number of collected insects. The results demonstrated that light traps equipped with 160-watt mercury lamps emitting white light collected significantly the highest number of this insect among the other tested lamps.
阿拉伯巨犀象虫（Fairmaire）（鞘翅目：金龟科）是一种危害棕榈树的害虫，可对树干和根部造成损害，并可对阿联酋（UAE）和阿曼、沙特阿拉伯、突尼斯等其他国家的草坪造成损害。本研究的目的是监测种群动态，并评估 6 种不同颜色（白色、绿色、红色、黄色、蓝色和红外线）和 2 种灯类型（汞灯和节能灯）的诱捕效果。该实验在 2 年期间（2010 年和 2011 年）在一个枣椰农场进行。结果发现，这种昆虫是一种一化性害虫，只有一个种群高峰。成虫于 4 月中旬至 5 月初出现在田间，种群数量持续增加，直到 6 月中旬达到最大值。9 月底后不再发现成虫。光周期与成虫数量变化有显著相关性。与其他测试的光色相比，汞灯发出的白光吸引了更多的阿拉伯巨犀象虫成虫。将汞灯的功率从 160 瓦增加到 250 瓦并没有显著增加收集到的昆虫数量。结果表明，配备 160 瓦汞灯并发出白光的诱虫灯收集到的这种昆虫数量明显高于其他测试灯。
