[Observation on the susceptibility of Anopheles sinensis to periodic Brugia malayi microfilariae].
OBJECTIVE
To explore the susceptibility of Anopheles sinensis to Brugia malayi microfilariae of different densities.


METHODS
The survival rate of mosquitoes, the rate of microfilariae penetrating through midgut, the mature rate of larvae into infective larvae (L3) and the mean number of L3 in the survived mosquitoes were observed.


RESULTS
With the microfilariae densities of 32.5 mf/microliter and 141.5 mf/microliter, the rate of larvae matured into L3 was 36.2% and 8.7%, respectively, the mean number of L3 recovered from infected mosquitoes was 8.24 and 0.30, respectively.


CONCLUSIONS
An apparently higher susceptibility of An. sinensis to B. malayi was found by using B. malayi microfilariae density of 32.5-66.4 mf/microliter.
