  1. Control 1 = No paint; Control 2 = Paint without insecticide at 1 Kg/6 m2. Culex = Cx. quinquefasciatus; T0 = 0 months after treatment, T6 = 6 months after treatment, T12 = 12 months after treatment, N = sample size per surface tested; (-) females had already died during the first hour. † = significant differences from control (P < 0.05).
