International Symposium on Arthropod Biodiversity and Ecosystem Services in Rice Environments and Official Opening of the Biodiversity Laboratory in Hainan University, Hai Kou, China

Anthropod-Conference-final-

The Hainan Project which started in 2010 has completed several expeditions and farmer surveys focusing on arthropod biodiversity in rice environments. The rich biodiversity of Hainan is illustrated by the 53 new species of spiders that the research discovered and some of them are named in honor of Chinese scientists.  The new species constituted about 15% of all the spider species found in the expeditions illustrating the biodiversity richness. Spiders perform the important function of predation that provides pest regulation services for pest management.

On 16 April 2013, Hainan University and the International Rice Research Institute will organize an international symposium and to officially open the Biodiversity Laboratory that will house all the holotype and paratype specimens of the new species as well as a reference collection of the 952 arthropod species collected in Hainan.  The Biodiversity Laboratory will serve as an important resource for research and education on arthropod biodiversity.

The Hainan arthropod conservation project conducted field expeditions and samplings and discovered 57 new and yet to be described spider species in rice and surrounding habitats. All 57 species are now described and published in a monograph by the University of the Philippines. Earlier the first new species,  Tetragnatha heongi  from the first expedition described and published. A paper on the general spider fauna of the Hainan Island was also published. In describing the new species and had them peer reviewed, species were named after famous Chinese scientists involved in spider research, taxonomy and rice research.  One species was named after Professor Jiaan Cheng and a plague commemorating the naming was presented to Professor Cheng in November 2012 at the International Conference Rice Planthopper Conference held in Hangzhou.

Professor Cheng in his nearly 50 years’ career played a significant role to shaping rice pest management He started his career in rice pest management in 1964 and contributed significantly to pest ecology and management in China.  He was appointed the vice president, the president of Zhejiang Agricultural University and later the vice president for research in when the universities merged into Zhejiang University.  Professor Cheng was a mentor to 45 graduate students and still continues to guide the future generation of pest ecologists.  Full descriptions of Professor Cheng’s contribution to rice pest management and the new spider species are available.

Distribution of sites where the 57 new species of spiders were discovered.

The spider species were discovered in 8 sampling sites,  Songtao (17 species), Danzhou (10), Dapo (9), Haoko (7),  Chengmai (5), Jianfengli (Yulingu) (5),  Lingshui (2) and Sanya (2 ). Most of the new species discovered were from sites west of the Wuzhi mountain range in the center, where rice growing is less intense and have high habitat biodiversity.  It has been shown that spider species richness is associated with bund habitat and insecticide use .
