Abstract: Objective To learn the influence of the earthquake in Wenchuan on vectors and vector borne disease,grasp timely the vector species and its density dynamics,and provide a reliable basis for the risk assessment of vector borne disease.Methods Investigate the density of rats,mosquitoes and flies in a large scale.Monitor the density of flies in the tents of living areas,trash-dropping places and washrooms daily.Survey the rats density with rat folders method,flies density with sticky flies plate and eyeballing method,mosquito density with trap-mosquito method and eyeballing method.Results The result showed that the density of rats and mosquitoes was relatively lower,and the density of flies was under the reference index as a whole.The flies density was higher in some places because there was still some trouble in the garbage disposal of kitchens and washroom.Conclusion We should strengthen the health and sanitation education to the victims,and try our best to do the disinfecion and vector monitor works at the victim temporary habitation.
