Figure 2From: Efficacy and non-target impact of spinosad, Bti and temephos larvicides for control of Anopheles spp. in an endemic malaria region of southern MexicoSpecies accumulation curves for aquatic insect species from experimental pools in southern Mexico. Pools were subjected to one of three larvicidal treatments or an untreated control. Curves were fitted to empirical results by quadratic or logarithmic regression. *Treatments followed by different letters differed significantly; analysis of covariance, Tukey test α = 0.05.Back to article page
