Zhejiang Provincial Key Laboratory of Biometrology and Inspection & Quarantine China Jiliang University Hangzhou 310018 China 2. Bureau of Agriculture of Wuzhongqu District of Suzhou City Jiangsu Province Suzhou 215128 China Abstract In order to understand the effect of tea-fruit intercropping on the population density and spatial distribution patterns of arthropod communities ten types of tea-fruit intercropped plantations were investigated in the East Dongtingshan Mountains Taihu Lake during the summer July harvesting season of 2009. This mountain is the original production site of the famous tea Dongtingbiluochun and has a long history of tea and fruit intercropping. The same experimental design sampling the same ten types of tea-fruit intercropped plantations was also implemented in the West Dongtingshan Mountains Taihu Lake during the spring April harvesting season of 2010. Data on species composition and population densities of arthropods between the intercropped fruit trees at the upper middle and lower layers of tea bushes and on and below ground level were obtained from each experimental plot for both locations and study periods. Our data indicates that 1 Overall results from the two locations and sampling periods were virtually the same. 2 The tea green leafhopper Empoasca vitis G the and the citrus spiny whitefly Aleurocanthus spiniferus Quaintance were the most dominant pest species regardless of intercropping types and location there were no significant differences in the * Y3100375 2008FY210500 ** 2010 *** E-mail han-insect@ 263. net 2010-11-08 2011-01-11
1472 48 species composition of other major pests and dominant natural enemies. 3 Species richness in the upper and middle layers of tea bushes abundance total number of individuals dominated by Homopteran insects in the lower layer of tea bushes and the biodiversity index of the middle layer of tea bushes were higher than in the other layers. 4 Among different types of tea-fruit intercropped plantations tea-citrus and tea-chestnut plantations had a higher arthropod species richness whereas both species richness and overall arthropod abundance were lower in tea-japanese allspice plantations. This suggests that the rational intercropping of tea plants with fruit trees can increase general arthropod biodiversity including that of species that exist between intercropped fruit trees or on or below the ground. Intercropping may significantly affect arthropod community composition.
