Mean number (± SE) of Anopheles larvae recovered from aquatic habitats that were non-exposed (predictor absent) and exposed (predictor present) to different moderating effects on Mageta Island in western Kenya

Predictor	N	Mean (± SE) number of Anopheles larvae		Exp (B)	P
		Predictor absent	Predictor present
Emergent plants	9	25.54 ± 0.57	1.87 ± 0.48	13.621	0.001
Fish predators	22	30.85 ± 0.69	0.10 ± 0.07	323.885	0.001
Direct sunlight	73	23.43 ± 1.29	23.32 ± 0.57	1.005	0.938

The test statistic {Exp (B)} and the level of statistical significance between the mean numbers of larvae in exposed and non-exposed habitats are shown for each predictor. ‘N’ refers to the number of larval habitats (out of 87) ‘exposed’ to the predictor variable. The rest of the habitats were ‘not exposed’ to the predictor
