Abstract: Objective To investigate the distribution,ecological feature and malaria transmission of Anopheles in Guangxi province.Methods Combining both of spot check and important site overall survey in Guangxi province,the data of vector survey in history were collected,described and analyzed.Results Anopheles minimusandAnopheles anthropophaguswere found in 78 counties and 15 counties,respectively.They fed mainly on human and sometimes on cattle.The human blood index of An.minimusandAn.anthropophaguswere 0.0458-0.1390 and 0.2912-0.6330,respectively.An.sinensis distributed widely in all parts of Guangxi.It fed mainly on cattle and sometimes on human.The sporozoite rates of An.minimus,An.anthropophagus,An.sinensisandAn.candidiensiswere 0.08%-8.11%,0.25%-1.85%,0.005%-0.32% and 0.06%-3.22%,respectively.Conclusion Above 4 species of Anopheles were vector of malaria in Guangxi.An.minimusandAn.anthropophagus were the chief vectors of malaria in mountainous and hilly areas respectively.An.sinensis andAn.candidiensiswere secondary vectors in malaria epidemic regions.
