Vectors of Wuchereria bancrofti in the Sepik Provinces of Papua New Guinea.
The vectors of Wuchereria bancrofti were investigated in two areas of the Sepik Provinces of Papua New Guinea. At the village of Yauatong, indoor-resting Anopheles punctulatus had an infection rate of 47.3% and an infective rate of 3.4%. No infections occurred in 382 Culex annulirostris obtained in night-landing catches. At the village of Yankok only An. koliensis contained infective larvae but An. punctulatus and Cx quinquefasciatus were infected. Probit values of the cumulative percentages of filariae-positive mosquitoes plotted against the logarithm of the corresponding filaria count are illustrated.
