Changing the larval artificial diet of E. insulana after seven days with the fresh one of the same diet or natural okra fruits. caused non significant short in the iarval and pupal duration end significant increasing the larval and pupal weight. adun emergency, fecundity and hatchability percentages in comparison with larvae continuously reared on artificial diet without change the diet until pupation. The use of honey solution etther alone or mixture with yeast or vitamin E instead of sugar solution alone or mixture with yeast or vitamin E in feeding spiny bollworm moths increased the quantity and viability of egg laid per female. The number of eggs per female were 146, 154, 149, 156, 166, 161 eggs, for sugar, sugar + yeast. sugar + vitsmin E, honey, honey + yeast and honey + vitamin E solutions, respectively. The numbers of eggs per female in presence of cotton boll or okra fruit were 183 and 178 eggs, respectively, which was higher than that obtained in absent of host plant (156 eggs per female).
