Abstract:An alien invasive species(Eleutherodactylus planirostris) which was considered one of the most successful invasive species of amphibians had been found in Honey Park in Shenzhen city center, southern Guangdong Province, China in July, 2017. This is the first record of this foreign species in mainland China. We conducted line transect surveys in municipal green-land and green belts around Honey Park from 10 July 2017 to 16 July 2017 in order to preliminary understanding how this species effects on native species. During our survey, Eleutherodactylus planirostristhe greenhouse frog was only found in Honey Park in three isolated distribution area, and showed higher population density than native species. We randomly collected 21 specimens including two kinds of color types, anatomy 10 of them and found that all adult individuals were females, the study of stomach contents showed Cryptopone sp. and Blattella bisignata Brunner, and no stomach contents were found in the specimens which were made on the alternate day. The proportion of adult and juvenile was 5/15 according to our first survey and 49/2 in the subsequently survey. The Shenzhen population was considered in a state of strong expansion through in this study on account of the large number of female individuals and fast growth rate and strong ability to digest of juvenile individuals through our surveys, and the plant and soil trade might be the major invasion path. . The invasion history of the greenhouse frog in Shenzhen City still remained unknown and long-term monitoring and research appears additional attention.
