From: Impact of involving the community in entomological surveillance of Triatoma infestans (Klug, 1834) (Hemiptera, Triatominae) vectorial control

Variables Entomological evaluation by PPCHLR, without community participation (Feb)a Entomological evaluation with community participation (Dec)b
Number of DUs visited 359 434
Number of DUs evaluated 109 354
Number of DUs sprayed after evaluation 57 43
Surface area evaluated (km2) 0.796 163.89
Cost 3809.90 1323.71
Cost related to the number of DUs visited 10.61* 3.05*
Cost related to the number of DUs evaluated 34.95** 3.74**
Cost related to the number of DUs sprayed 66.84*** 30.78***
  1. *χ2 = 4.57, p < 0.0325; **χ2 = 24.64, p < 0.0001; ***χ2 = 13.22, p < 0.0003
  2. aCost without community participation was constituted by the ‘expenses’ (fuel and travel wages) incurred by PPCHLR
  3. bCost with community participation was constituted by the sum of the expenses incurred by PPCHLR and inputs used (brochures, gloves, and fuel) for traveling to the study area to train householders or to collect bugs
