Fig. 5. Path diagrams of the relationship among salinity, growth parameters and final pupal dry mass in Aedes aegypti and Ochlerotatus taeniorhynchus. Solid lines indicate positive and broken lines negative path coefficients; the values of the path coefficients are indicated by line thickness. Coefficients that are not significant at P<0.05 are not shown. U, unexplained variance. The univariate (net) coefficient describing the overall effect of salinity on pupal dry mass is shown by the vertical arrows at far left of the figure.
