ABSTRACT We report the presence of ladybird Clitostethus arcuatus (Rossi) (Coleoptera: Coccinellidae) in citrus orchards infested by the woolly whitefly Aleurothrixus floccosus (Maskell) (Hemiptera: Aleyrodidae) at Pica Oasis and Matilla, Tarapacá Region, Chile. In addition, we describe some aspects of its behavior and suggest it use in augmentative control biological programs to management whiteflies populations in desert agroecosystems.
