Fig 6. Effects of full (ODRS) and restricted (RODRS) outdoor residual spraying of insecticide on the numbers of P. orientalis in Jebel-Algana village, Gedarif state, Sudan.

Sandflies 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 16 trap nights, except 32 trap nights on days -4 and +4, and 19–21 trap nights on day 76 in (C). Error bars represent the interquartile range. Note differences in the Y-axis range. Sand fly trapping was conducted between 31st March-20th June 2017.
