摘　　要：2018—2020年间,在内蒙古黄花沟旅游景区发现一种蝗虫种群数量呈逐年增加趋势。该蝗虫经鉴定为蛛蝗[Aeropedellus reuteri(Miram)],属直翅目(Orthoptera),槌角蝗科(Gomphoceridae),蛛蝗属(Aeropedellus),为内蒙古地区外来侵入新分布种。发生调查表明,景区内人工林地内和风力发电塔基部周围种群密度相对较低,林缘之外和公路两侧种群密度相对较多,平均虫口密度可达35.2头/m2。景区外围区域种群密度逐渐减低。与国家标准(NY/T2736-2015)中的土蝗防治指标(10头/m2)相比,在景区内已发生成灾。这是蛛蝗首次以害虫角色在内蒙古地区发生为害,亦是国内外首次发生成灾。本文对蛛蝗的传入、扩散风险及潜在经济危害性也进行了初步评估。Abstrct During 2018 to 2020,a locust population was found to increase year by year in Huanghuagou,a tourist area in Inner Mongolia.The locust was identified as Aeropedellus reuteri(Miram),belonging to Orthoptera,Gomphoceridae and Aeropedellus,and it is a new invasive species in Inner Mongolia.The occurrence investigation shows that population density of the locust is relatively low in forest plantation and nearby foundations of the wind power tower,but relatively high outside the forest edge and along the roadside,and the average population density in Huanghuagou reaches 35.2 heads/m2.The population density gradually decreases out of the tourist area.According to the locust control index(10 heads/m2)set by national standard(NY/T2736-2015),there was an outbreak in the area.It was the first outbreak of the locust species in Inner Mongolia,also the first outbreak in the world.A preliminary risk assessment of its introduction and spread and potential harm to economy were also given.
