Mortality (Mort.), feeding deterrent index (FDI), relative growth rate (RGR), relative consumption rate (RCR) and efficiency conversion of ingested food (ECI) of S. granarius adults fed for 5 days on flour disks treated with increasing concentrations of D. viscosa water extract. Values in the same column followed by the same letters are not significantly different at P = 0.05 (Tukey HSD test).
