Age structure of some mosquito populations in a savanna area in Surinam

ABSTRACT

From the beginning of January until the end of September 1973 weekly collections of adult mosquitoes were made near Powaka, an Amerindian village, located in the savanna belt of northern Surinam. Three mosquito species were abundant enough to permit regular determinations of the age structure of the populations. Some 5,500 specimens were dissected, 1,354 of Culex spissipes, 1,099 of C. mollis and 3,037 of C. portesi. C. portesi constituted a serious threat to the health of man throughout the year, whereas C. spissipes was especially dangerous during July and August.(AU)
