Table 1. Mixed linear regression model of the impact of target deployment on tsetse catches in the Boffa focus.

Fixed effects	Nb of coefficient		Means of catches/day Least squares (± standard error)	F ratio	Prob. >F
Sampling round	5		-	3.7459	0.0027
Target deployment	1	yes	2.99 (± 1.29)	26.7620	< 0.0001
		no	18.17 (± 2.63)

Mixed linear regression was used to model the response variable that was the mean number of catches/day/trap. The trapping site was included as a random effect and the period of sampling and deployment of impregnated targets as fixed effects.
