Abstract: Objective To find out the relationship between malaria morbidity and distribution of their vectors. Methods Cross section study was employed for malaria cases investigation,vectors survey and its distribution. The vectorial capacity was evaluated via human blood index survey. Results The malaria endemics could be divided into one-vector-endemics in which only Anopheles sinensis is recorded,and two-vector-endemics in which A.sinensisandA.anthropophagusare recorded. The vectorial capacity in two-vector-endemics is as 44.47 times as that in one vector endemics. The malaria cases of two vector endemics ranges from 81.38% to 93.84% of the total cases of Hubei Province. Conclusion The malaria epidemic is related with the distribution ofA.anthropophagus. It suggested that the malaria control should focus onA.anthropophagus.
