Studies on the susceptibility of a large urban population of Aedes aegypti to infection with dengue viruses.
A large urban population of Aedes aegypti in Jakarta, Indonesia was studied for one year to determine whether it was homogeneous in terms of susceptibility to dengue viruses and whether seasonal changes in susceptibility to dengue viruses occurred. Mosquitoes from several districts in Jakarta showed a low but homogeneous susceptibility to dengue 2 virus from November 1975 to April 1976. In June 1976, increased susceptibility to dengue 2 virus was observed among some of the subpopulations of Ae. aegypti, and higher infection rates and increased variation were observed among these mosquitoes during the rest of the study period. Correlation with confirmed DHF cases in Jakarta was discussed.
