The life history, development, and post development traits of Spodoptera exigua (Hübner) were studied on different host plants (Allium cepa L., A. Fistulosum L., Ricinus communis L., Trianthema portulacastrum L., and Zea mays L.) in the laboratory. Significant differences were observed in the life history, larval development, total development time, post developmental period, and fecundity among the host plants tested for both sexes of S. Exigua. Suitability for feeding and development in decreasing order are as follows: T. Portulacastrum, R. Communis, A. Fistulosum, A. Cepa, and Z. mays. based on proximate analysis, levels of crude fiber and percent moisture rather than crude protein, crude fat, and total sugar of host plants had influence on feeding suitability and development for S. exigua.
