Wadi Telah in the St. Katherine region of the Sinai, Egypt, is a high mountainous habitat with an outstanding biodiversity. At the same time, it is a preferred tourist destination and hiking area. It order to find out whether hiking has a negative effect on the insect populations in the area, a survey was carried out for the spatial variation of the diversity of gall-inducing insects at different distances from the main hiking trail. A total of 42,317 specimens of six gall-inducing insect species was found, belonging to three orders. Both the species richness and the abundance of gall-inducing insects were significantly positively correlated with the distance from the trail. In most species, the proportion of galled plants was significantly positively correlated with the distance from the hiking trail. These results indicate that even the “soft” disturbance resulting from a hiking trail has negative environmental impacts.

埃及西奈地区圣凯瑟琳地区的瓦迪特拉（Wadi Telah）是高山生境，生物多样性卓著。同时，它是首选的旅游目的地和远足区。为了确定远足是否对该地区的昆虫种群有负面影响，对离主要远足径不同距离的胆汁性昆虫多样性进行了空间调查。共发现了423种标本，其中包括六种引起gall虫的昆虫，属于三个等级。gall虫的物种丰富度和丰富度均与到该路径的距离呈显着正相关。在大多数物种中，枯萎植物的比例与到远足径的距离呈显着正相关。
