STUDIES ON THE MOSPQUITO COMMUNITIES OF 15 PROVINCES IN CHINA

The mosquito communities were investigated in 15 provinces in China. The resultsshowed that there were 12 dominant species of mosquitoes. They were: Aedes dorsalis, A.vexans, A. kasachstanicus, A. albopictus, A annandalei, Culex modestus, C. tritae-miorhynchus, C. pipiens quinquefasciatus, C. pipiens pallens, C. shebbearei, Anophele sinensis,Armigeres subalbtus. The diversity index vaule of mosquito communities were: Yunan(1. 8697), Zhejiang (1. 6366), Guangxi (1. 4106), Liaoning (1. 4039), Fujian (1. 1773),Jiangsu (1.1524), Guangdong (1. 1103), Tianjin (0.9582), Shandong (0. 8766 ), Xizang(0. 8377), Inner Mogolia (0. 7120 ), Xinjiang (0. 6932 ), Jilin (0.5974 ), Heilongjiang(0.3715), Gansu(0. 3559). Mosquito communities in 15 provinces could be divided into threegroups by the systematic clustering and principal component analysis (PCA). The first groupincluded Guangxi, Guangdong, Jiangsu, Fujian, Zhejiang and Yunan. The second group in-cluded Xizang, Xingjiang, Neimenggu, Gansu, Tianjin, Shandong, Liaoning and Jilin. Thethird group included only one province, i. e. Heilongjiang Province.
