Correlations of climatic, elevation, soil and vegetation index with the sand fly vector densities in 48 stations across Morocco. The correlations examined the relationship between male and female Phlebotomus papatasi and Phlebotomus sergenti densities to these environmental factors. Pearson correlation coefficient is presented in the table with P values between brackets
