The present investigation aims towards furnishing information about the effect of four diets namely, castor beans, cotton, sweet potato and alfalfa for Spodoptera littoralis larvae, on pupal development and egg production of moths. Evaluatin of the response of the insect to the tested diets was carried out on the 5th and 10th generation offsprings of the standard laboratory colony. All data were statistically subjected to Fichers test for analysis of variance to determine its significances at 0.01 level. The pupal weights showed highly significant differences for the tested hosts in 5th and 10th generations. The castor proved to be the best diet followed by sweet potato and cotton as a group. The lowest pupal weight resulted from feeding on alfalfa. The egg production of moths emerging from larvae fed on the four diets showed no significant differences. Zusammenfassung Die Wirkung von 4 Nabrungspflanzenarten auf die Puppenentwicklung und Eiproduktion von Spodoptera littoralis Als Testpflanzen wurden verwendet: Castorbohne, Baumwolle, Süßkartoffel und Alfalfa. Die Kontrollen wurden nach der 5. und 10. Laborgeneration durchgeführt. Alle Daten wurden statistisch behandelt. Das Puppengewicht zeigte hochsignifikante Unterschiede zwischen den Nahrungspflanzen an beiden Kontrollen. Die Castorbohne erwies sich als beste Nahrung, gefolgt von Süßkartorffel und Baumwolle. Die Eiproduktionen der Falter, welche aus verschieden ernährten Raupen hervorgingen, zeigten keine gesicherten Unterschiede.
