Table 1. Mean (± SEM) survival time, and larval, pupal, and cumulative mortality of Copitarsia decolora larvae fed with artificial diet supplemented with hexane, ethyl acetate, acetone, methanol, and aqueous extracts of Trichilia americana bark at 100, 500, 1,000, and 1,500 ppm.

Treatment	Concentration ppm	Mean larval survival time (d)	Larval mortality (%)	Pupal mortality (%)	Cumulative mortality (%)
Means within the same solvent followed by the same letter are not significantly different (P > 0.05; Holm-Sidak test). *Control diet is the same for all the solvents.**No larvae reached the pupal stage.
