Comparison of human landing catch (HLC) and bed net trap (BNT) sampling methods for Anopheles funestus and Anopheles gambiae s.l., November 1992 to May 1993^*

Method	No. collected	Mean per night (95% CI)	Relative rate (95% CI)	P value
An. funestus
HLC	730	1.25 (1.05, 1.45)	1.00†	NA‡
BNT	917	1.57 (1.34, 1.79)	1.27 (0.92, 1.76)	0.145
An. gambiae
HLC	2408	4.12 (3.47, 4.78)	1.00†	NA‡
BNT	1389	2.38 (2.01, 2.74)	0.57 (0.44, 0.74)	< 0.001

^*Relative rates of collection and associated 95% confidence interval (CI) and P value were calculated using negative binomial regression. P values indicate the probability that the relative collection rate of BNT sampling was not different from that of HLC.

^†HLC was used as the reference sampling method.

^‡NA = not applicable.
