Objective To control rat density and ensure public health security at the capital airport. Methods In a routine rodent density investigation carried out by Beijing Capital Airport Entry-Exit Inspection and Quarantine Bureau from October 15 to 17, 2009, it was found that the average rodent density in some areas of the capital airport was up to 5.17%, which exceeded the standard limit of International Hygiene Airport. An emergency response was immediately launched according to the Frontier Public Health Emergency Response Program, including the establishment of an emergency response team, development of the rodent control plan, administration of rodenticides and deployment of glue traps to reduce the rat density. Results After 30 days of emergency treatment, the rodent density decreased to 0.50%, and the monitoring after 40 days revealed zero rat density (based on the night trap measurement). Conclusion The Frontier Public Health Emergency Response Program played a crucial role to proper handling of rodent density increase.

【Abstract】 Objective To study the rodent population composition and its seasonal fluctuation at Beijing Capital international airport (BCIA) from May. to Sep. of 2006-2008, and provide the evidence for the rodents control at BCIA during Olympic Games. Methods The special rodent investigation for Olympic Games was adopted, and the investigation data was analyzed. Results Rattus norvegicus and Mus musculus were the dominant species at BCIA, and R. norvegicus was mainly in the room, while M. musculus mainly in outdoor environment. The constituent ratio of Apodemus agrarius reduced year after year. The average rodent densities were 0.86%, 0.29% and 0.26% in 2006-2008, showing the downward tendency. Conclusion A special rodent investigation should be carried out at frontier port before the important international events, especially know the effect of important construction items on the rodent density and its population composition.

【Abstract】 Objective To master the species and seasonal fluctuation of mosquitoes, and provide scientific basis for mosquitoes control in Beijing ports. Methods CO2?baited trap and net trap methods were used for the surveillance of adult mosquitoes, and the scoop dipping method for the surveillance of larvae. Results A total of 14 270 mosquitoes were collected, belonging to 4 genera and 6 species. They were  Anopheles sinensis, Culex pipiens pallens,  Cx.tritaeniorhynchus,  Aedes albopictus, Ae.vexans  and  Armigeres  subalbatus.  As  many  as  114  mosquito  larvae  were  collected,  which  were  Cx.pipiens  pallens  and Cx.modestus. The dominant specie was Cx.pipiens pallens and its active peak was September. Conclusion The integrated management should be taken for a long time to control mosquitoes in Beijing ports.

【Abstract】 Objective To study the influence of the Beijing Capital International Airport T3 terminal construction on circumjacent rodent composition and density, and provide the evidence for the rodents control. Methods The night trapping method was used to investigate the rodent composition and density in the representative environments around the T3 terminal construction sites monthly. Results There were 102 rats belonged to three species caught in T3 terminal construction sites. The dominant specie was Mus musculus, accounting for 67.65% of the total. Rattus norvegicus and Apodemus agrarius accounted for 21.57% and 10.78%, respectively. There was significant difference in the rodent composition from 2005 to 2008（χ²＝17.24，P＝0.008）, and the average rodent density reduced year after year. Conclusion The construction of T3 terminal led to the change of environment, resulting in change of rodent composition and its density. It should strengthen the surveillance of rodent for the important construction item around its peripheral environment and carry out thoroughly the killing of rodent.

【Abstract】 Objective To master the fly species and population composition at Beijing port and provide scientific evidence for fly control. Methods The baited fly traps method was used in this study. Results There were 30 species, 16 genera, 5 families of flies captured from April to November of 2006 and 2007. The annual average fly density was 59.7 flies/(cage ·day). There were two peaks, one was in May and the other was in September. Conclusion It was important to clean out the breeding sites for the control of flies at Beijing port.

【Abstract】 Objective To master the species and composition of ectozoa on the body of the rodents and hedgepig in Beijing ports. Methods Mus musculus, Rattus norvegicus, Apodemus agrarius and Erinaceus europaeus were captured by night trapping method, and the ectoza were collected from the body of them. Results A total of 282 ectozoas were picked up and identified, belonging to 12 species. It included 61 gamasid mite belonging to 6 species, 203 ticks belonging to 4 species, 13 chigger  mite  belonging to 1 species and 5 fleas belonging to 1 species. Beside the above species, there were Laelaps echidninus, Ls.jettmari, Ls.nuttalli, Haemolaelaps glasgowi, Hirstionyssus sunci, Macrocheles muscaedomesticae, Dermacentor silvarum, Dermacentor nuttalli, Rhipicephalus sanguineus, Haemaphysalis longicornis, Leptotrombidium pallidium, Xenopsylla cheopis, respectively. Conclusion The infestation ratio and the ectozoa index of these hosts were lower with the exception of hedgepig.
