The Plant Quarantine Status And Analysis Of Exotic Pest Intercepted At Yunfu Port During 2012-2016

With the acceleration of global economic integration,China interflows with other countries more and more frequently.A growing number of alien species which were carried by the passengers,cargos,mails and ships entered to the ports of China.The risk of exotic pest invasion in China is also increasing.The Yunfu port is the largest inland port in Guangdong Province.Stones such as marble and granite etc.are mainly imported goods,which accounting for about 90% of the total goods in this port.Most of the stones come from some developing countries from the Middle East.These stones were imported directly from local mine after simple cutting processing,with high risk of carrying alien pests.To investigate the data of alien species carried by imported goods in Yunfu port in recent years and to provide information for further establishing the biosafety control system in the entry-exit inspection and quarantine department,this paper analyzed the situation of plant quarantine and the data of invasive pests intercepted at Yunfu port during 2012~2016.The results showed that a total of 139 species of exotic animals and plants were intercepted at Yunfu port during 2012-2016,which including 85 species of insects(intercepting 195 times),39 species of plants(intercepting 119 times),1 species of mite(intercepting 5 times),2 species of nematodes(intercepting 10 times),5 species of snails(intercepting 12 times),6 species of spiders(intercepting 204 times)and 1 species of fungus(intercepting 2 times).Among them,Theba pisana Müller was firstly intercepted in C hina,Scolytus multistriatus and Emex spinosa were intercepted for the first time in Guangdong Province,and Solenopsis invicta,Heterobostrychus aequalis,Bactrocera dorsalis,Solanum torvum,Callosobruchus maculatus and Xanthium sp.were firstly intercepted in Yunfu port.These interception works of plant quarantine prevented effectively the invasion and spread of alien pests at Yunfu port in recent years.In addition,the imported stones from India,Pakistan,Iran and Turkey etc.were with higher risk of carrying alien pests because of their packaging extensive and poor sanitary conditions.According to the above results,the measures for enhancing quarantine and inspection to imported stones were provided in this paper.
