Abstract

Dysdercus fasciatus and D. cardinalis were studied in the field to ascertain their occurrence and relative abundance on different host plants at Masongaleni near Kibwezi, Machakos District, Kenya. It was carried out using a complete randomized block with four replicates. It was shown that D. cardinalis occurred more commonly on its wild host plants than D. fasciatus. D. cardinalis was also commonly found feeding on Sterculia spp. on which D. fasciatus was not recorded during these studies. Neither species was recorded from baobab trees.

Résumé

Les enquete sur Dysdercus fasciatus et D. cardinalis ont étè effectuèes à Masongaleni, prés de Kibwezi, Machakos District (Département), au Kenya afin d'établir leur existence et leur abondance rélative sur les plantes hotes variées. Compte à insecte sur sauvage plantes hotes réussirai emploieant à l'aventure complet bloc modele au project avec fois quatre repetition. On a dècouvert qu'il y avait plus de D. cardinalis que de D. fasciatus sur les plantes hotes dans l'etat naturel. On a également trouvé une grande quantité de D. cardinalis parasiter sur Sterculia spp. mais il n'y avait aucune prèsence de D. fasciatus pendant toute l'etude. On n'a trouve aucune de ces espèces de parasites sur les arbres baobabs.
