During the cotton seasons of 1974 and 1975, a survey was carried out to examine the list of parasitoids of the cotton leafworm Spodoptera littoralis. Five parasitoids were found parasitising the immature stages of the pest. Four of them belonged to order Hymenoptera and the 5th was from order Diptera. Certain field and laboratory observations on Euplectrus laphygmae Ferr. (Hymen., Eulophidae), and Strobliomyia orbata Wield. (Dipt. Tachinidae) were recorded. The parasitoid Microplitis rufiventris Kok. (Hymen., Braconidae) proved to be an effective solitary larval parasitoid on S. littoralis in cotton fields in Egypt; it was more capable of tolerating the adverse conditions than its host. Zusammenfassung Freiland‐ und Laboruntersuchungen über die Parasitoiden von Spodoptera littoralis (Boisd.) (Lep.; Noctuidae) in Alexandria Während der Baumwollsaison 1974–1975 wurde das Spektrum der Parasitoiden der Baum‐wolleule, S. littoralis , untersucht. Es wurden 5 Arten gefunden: 4 Hymenopteren und 1 Diptere. Freiland‐ und Laborbeobachtungen an Euplectrus laphygmae (Hymen., Eulophidae) und Strobliomyia orbata Wield. (Dipt., Tachinidae) wurden durchgeführt. Der Parasitoide Microplitis rufiventris Kok. (Hymen., Braconidae) erwies sich als wirksamster solitärer Larvenparasit der Baumwolleule in ägypten. Er vertrug ungünstige Umwelt‐faktoren besser als sein Wirt.
