Coleopteran diversity was compared between more and less disturbed lowland evergreen deciduous forests located in Phou Phanang National protected area, Lao PDR. Using window traps and pitfall traps and collecting beetles from March until December 2018, a total of 6243 specimens were obtained. The number of morphospecies found in the less disturbed forest was significantly higher as compared to the more disturbed forest. Slightly more morphospecies were found in the window traps compared to pitfall traps and a significantly higher number of morphospecies were found in the wet season (June and September collections), compared to the dry season (March and December collections). Similarly, more than twice as many specimens were found in the less disturbed forest, compared to the more disturbed forest and also again more were found in the wet season, in particular predators. The data presented here indicate that so far largely undisturbed forests in Lao PDR need to be better protected from human exploitation such as logging.

老挝森林栖息地的甲虫生物多样性取决于人类开发水平

比较了位于老挝 Phan Phanang 国家保护区的受干扰程度高和受干扰程度低的低地常绿落叶林之间的鞘翅目多样性。2018年3月至2018年12月，利用窗诱捕器和陷阱诱捕器收集甲虫，共获得6243个标本。与受干扰程度较高的森林相比，在受干扰程度较低的森林中发现的形态种数量明显更高。与陷阱陷阱相比，在窗口陷阱中发现的形态种略多，与旱季（3 月和 12 月的收集品）相比，在雨季（6 月和 9 月的收集品）中发现的形态种数量明显更多。同样，在受干扰较少的森林中发现的标本数量是受干扰较严重的森林的两倍多，而且在雨季发现的标本数量也更多，尤其是掠食者。此处提供的数据表明，迄今为止，老挝人民民主共和国大部分未受干扰的森林需要得到更好的保护，使其免受伐木等人类剥削。
