Cost related to the number of DUs evaluated	34.95**	3.74**

^*χ² = 4.57, p < 0.0325; **χ² = 24.64, p < 0.0001; ***χ² = 13.22, p < 0.0003
^aCost without community participation was constituted by the ‘expenses’ (fuel and travel wages) incurred by PPCHLR
^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
