目的了解深圳大鹏半岛入侵螺类物种。方法于2012年8月至2013年1月对深圳大鹏半岛进行软体动物资源调查,通过贝壳形态学观察等鉴定入侵螺种。结果大鹏半岛境内发现4种入侵螺类,均为医学贝类,分别为褐云玛瑙螺(Achatina fulica)、小管福寿螺(Pomacea canaliculata)、尖膀胱螺(Physa acuta)和藁杆双脐螺(Biomphalaria straminea)。其中尖膀胱螺在全部采集地点均有发现,褐云玛瑙螺和小管福寿螺在除杨梅坑外的调查点均有分布,藁杆双脐螺仅分布于大鹏镇。结论 4种重要外来螺类在深圳大鹏半岛广泛入侵,鉴于其在疾病传播和农业生产上具有的潜在危害,需加强预防控制。
Objective To understand the invasive species in Shenzhen Dapeng Peninsula. Methods From August 2012 to January 2013, a survey of mollusk resources was carried out in Shenzhen Dapeng Peninsula, and the invasive species were identified by morphological observation of shellfish. Results Four kinds of invasive snails were found in the Dapeng Peninsula. They were all medicinal shellfish, including Achatina fulica, Pomacea canaliculata, Physa acuta, Biomphalaria straminea). Among them, Aphelenchoides cinnabarinus was found in all the collection sites. Aralia elata and Tuberosa snails were found in the survey sites except for Yangmei pit, and the snakes were only distributed in Dapeng town.
