Abstract

Published information was used to compile a summary of natural enemies (parasitoids, predators and diseases) reported attacking Spodoptera litura (F) under field conditions. Species (71) of insect parasitoids in seven families of Hymenoptera and two families of Diptera were listed as parasitoids of different stages of S. litura. Predatory insects (36) belonging to 14 families and 12 species of spiders from six families have been reported to feed on this species. Four protozoan, four fungal, seven bacterial, four each of viral and nematode species were also reported to be the pathogens of this species. Published information suggested that periodic releases of large number of egg parasites could help in suppressing populations of this pest. There is a considerable scope for increased attention to the role of natural enemies as component of integrated pest management programmes of S. litura.

Résumé

Compte rendu mondial des ennemis naturels et des maladies de Spodoptera litura (F.) (Lépidoptéres: Noctuides): Des informations publiées ont servi de source pour la compilation de ce compte rendu des ennemis naturels (parasites et prédateurs) et des maladies qui s'attaquent à Spodoptera litura (F.) en milieu reel. Soixante-neuf espèces d'insectes parasitoïd parmi sept families des Hyménoptéres ainsi que de families des Diptères sont classées comme parasites des différents stadesde S. litura. Trente-six insectes prédateurs, appartenant à 14 familleset 12 espèces d'araingnées provenant de six families se nourriraient de cette espèce. Quatre protozoares, quatre moisissures, sept bactéries, quatre virus et cinq nematodes seraient également des agents pathogènes de cette espèce. Les information publiées laissant à croire que des introductions périodiques des parasites des oeufs en grands nombres permettraient de supprimer la population de Spodoptera. Les ennemis naturels offrent des possiblités importantes pour jouer un rôle clé dans des programmes de lutte intégrée centre S. litura.
