Abstract: Objective:To ascertain habits and characteristic and biting blood taxis of Anopheles anthropophagus in different area for the scientific basis of malaria prevention.Methods:The density of An.anthropophagus was investigated in the house and cattle pen and pigpen once each ten day in July to September. An.anthropophagus biting rate and activity peak at all night,by induce of mosquito net and peak of season in the bed net.Biting taxis of An.anthropophagus was observed in different host.Results:The average density of An.anthropophagus was 5.70 each fifty net,and 7.44 each man and half night,and 6.41 every hour in Cattle pen,and 2.37 every hour in pigpen.The season peak of An.anthropophagus was the last ten-day period of August to the first ten-day period of September and the activity peak was 23∶00-1∶00 in the night.The biting rate was 5.049 3,and the suck blood habits was 0.240 6 that is 7.76 times higher than An.sinensis's.The taxis man blood was 89.75 per cent and the average of transmission malaria was 1.731 5,that is 8.25 times higher than An.sinensis's.Conclusion: An.anthropophagus was emerging in house and prefering man blood,and is important vector of malaria.
