(A) Mean number of Anopheles females collected per sample in June through July from 1993 through 2011 using bed net traps (BNT; 1993–1997), light traps (LT; 2002–2008), and human landing catch (HLC; 2011). (B) Mean number of Anopheles females collected, adjusted for comparison to HLC sampling using the relative rates of BNT to HLC (1993–1997) and LT to HLC (2002–2008). (C) Proportion of total Anopheles females collected identified as either Anopheles funestus or Anopheles gambiae s.l. Error bars indicate 95% confidence intervals. Data were not available from 1998 to 2001, 2009, and 2010.
