Abstract
MB Nathan Bancroftian filariasis in coastal north Trinidad West Indies intensity of transmission by Culex quinquefasciatus Transactions of The Royal Society of Tropical Medicine and Hygiene Volume 75 Issue 5 1981 Pages 721–730 https//doiorg/101016/0035920381901632The intensity of transmission of Wuchereria bancrofti was measured in a coastal community in north Trinidad where 15 of the residents were microfilaraemic The only significant vector Culex quinquefasciatus was studied in detail to determine seasonal abundance longevity infection and infectivity rates Only 2·1 of the indoor biting population and 7·0 of the indoor resting population were infected The daily mortality rate of the vector increased with age from 27 at four days to 44 to 47 at 12 days and is considered to be an important factor contributing to the low infectivity rate 0·1 The mean number of C quinquefasciatus bites received by a resident of the village during the year of observation was estimated to be 17948 of which 14 were from mosquitoes harbouring infective larvae of W Bancrofti The results from similar studies elsewhere are outlined but the need for standardization of procedures is emphasized before more reliable comparisons can be made
