Figure 2From: Implications of bio-efficacy and persistence of insecticides when indoor residual spraying and long-lasting insecticide nets are combined for malaria preventionResults of monthly bioassays showing residual activity of various IRS compounds sprayed on panels (1 sq metre each) lined with Mikeka (i.e. Mikeka panels) or mud (i.e. mud panels). The data were corrected using Abbot’s formula[27] to account for unexpectedly high mortalities in the controls. The controls consisted of panels lined with unsprayed mud or Mikeka.Back to article page
