  1. N2 number of Anopheles specimens dissected, PR parity rate. For the PR distribution, values between An. gambiae s.l. and An. funestus s.l.  were significantly different overall (Chi-square test; P < 0.05). There were no significant differences between outdoor and indoor PR for both species (Chi-square test; P > 0.05). CI confidence interval
