Effects of outdoor residual spraying of insecticides (ODRS) on the numbers of P. orientalis in Umsalala village, Gedarif state, Sudan. Sand flies were captured by sticky traps set at outdoor sites (A) and peridomestic sites (B), and by CDC light traps set at outdoor sites (C). Each point represents the median numbers of P. orientalis from 10–14 trap nights (A & B), or 15–16 trap nights with exception of 23–24 trap nights on day 43 (C). Error bars represent the interquartile range. Note differences in the Y-axis range. Sand fly trapping was conducted between 2nd May-16th June 2017.
