ABSTRACT
Aphids host-plant preference was assessed in six cultivars of payaya (Tainung 01, Baixinho de Santa Amalia, BH-65, Red Lady, Golden, Sunrise) at the UCTB papaya collection in Jagüey Grande, Matanzas. Two leaves per plant were taken as samples during eight months and the number of aphids and natural enemies species on both sides of the leaves were counted. The identified aphids were Toxoptera citricida (Kirkaldy), T. aurantii (Boyer) y A. spiraecola (Pacth). The Chrysopa sp. y Adalia decempunctata L. eggs were observed. BH-65, Golden, Tainung 01, y Red Lady were the most prefered cultivars by aphides. Baixinho de Santa Amalia y Sunrise Solo de Brasil were the less prefered cultivars.
