Ticks can transmit a wide range of pathogens, posing a serious threat to human and animal health. In order to lay the theoretical foundation for tick control in Asia and Africa, we review the reports published in the past five years on ticks and tick-borne pathogens in Mongolia, China (only Xinjiang Uygur Autonomous Region and Qinghai province), Pakistan, and Egypt along the migration routes of migratory birds. The highest number of tick species (51) were reported in Pakistan, followed by Xinjiang and Qinghai of China, Egypt, and Mongolia. Only 11 tick species were reported in Mongolia. Most of the ticks found in these regions belonged to the family Ixodidae. The majority of reported tick-borne pathogens were zoonotic, including the genera of Anaplasma, Rickettsia, and Coxiella. Birds are hosts of various ticks and potential carriers of tick-borne pathogens. Therefore, the migration of birds from East Africa to West Asia may facilitate the spread of ticks and tick-borne pathogens along these regions.

　　【Abstract】　Objective　To grasp the population density and its seasonal fluctuation of primary vectors in Jinhua city，and to provide the scientific basis for the control of vector. Methods　The light-trapping and cage-trapping were conducted to monitor the density of mosquitoes and flies respectively, as well as the night trapping and cockroach paste for rats and cockroaches. Results The average density of mosquitoes in Jinhua city was 12.47/(man·hour) from 2005 to 2007, of which, Culex pipiens pallens was the dominant specie, accounting for 94.46%, followed by Armigeres subalbatus (3.65%) and Anopheles sinensis (1.16%). Flies density index was 50.03/cage and Chrysomya megacephala and Lucilia sericata were the dominant species, which accounted for 36.05% and 24.56% respectively. The density of cockroaches was 126.74/100 nights·pages, and the dominant specie was Blattella germanica (97.95%). There were 135 rats caught and the rats density was 0.33%. Of which, the dominant specie was Rattus norvegicus (51.85%). Conclusion　The main control targets  were Cx.pipiens pallens, Cx.megacephala, L.sericata, B.germanica as well as R.norvegicus in Jinhua city, so it should take the integrated measures to reduce the density of main vectors by firstly managing environment according to the characteristics of its breeding, habits and seasonal fluctuation.
