Abstract: Objective To find out the distribution and the correlation of introduced mosquitoes and microclimate factors on entry international ships,and provide technical supports for the surveillance and control of the introduced mosquitoes at seaports.Methods The places where the mosquitoes dwelled in the ships were investigated,and the microclimate factors including temperatures,relative humidity and wind speeds were measured at quarantine anchorage of Qinhuangdao port,and the data was analyzed.Results 168 entry ships were checked from April to October 2005.The positive rate of entry ships carried the introduced mosquitoes was 64.28%(108/168).The introduced mosquitoes appeared when the temperature exceeded 15 ℃ at the early of May,and it basically disappeared when the temperature was under 15 ℃ at the mid-ten days of October.There was the positive correlation between the densities of introduced mosquitoes and the temperature and the relative humidity.Mosquito could not fly when the wind speed was higher than 3 m/s.Conclusion It showed that the introduced mosquitoes population on entry ships was close relationship with the microclimate factors especially temperature and humidity.So it was advised the surveillance and control of the introduced mosquitoes carried by entry ships from abroad should be carried out properly.
