Abstract: Objective:To understand the role of human race and vector behaviors in malaria transmission.Methods:Behaviors of Anopheles minimus in resting,man-biting and night-acting were observed for one year at the three selected sites.The subjects were interviewed person by person by using human behavior questionnaires,meanwhile,a serological sample was collected from each subject and then detected in lab.The data were analyzed by statistics.Results:Resting density and nearby man-biting rates of An.minmus were completely correlative(r=1).Indirect fluorescence antibody test(IFAT) positive rates were positively correlated with man-biting rates(r=0.69) and resting densities(r =0.62) respectively.Human outdoor sleeping behaviors,over-night in field shacks and going to bed after active peak of An.minmus(22∶00pm) increased significantly malarial infection.Not only the size of An.minmus population affected IFAT positive rates,but also the length of its annual activity time and the degree of human exposure to its bite too.Conclusion:Human and vector behaviors are important determining factors in malaria transmission.
