Argudin, M.F., & Dominguez, G.G. 1984 Dinamica estacional de U. citri Comstock (Homoptera: Diaspididae) en lima persa en zonas de Guira de Melena. [Seasonal dynamics of U. citri Comstock (Homoptera: Diaspididae) on orange in zones of Guira de Melena.]. Centro Agrícola 11(3): 109.

Notes: Unaspis citri on the bark of orange trees in Cuba was sampled frequently between November 1978 and June 1983 to obtain information on its seasonal dynamics. A density-dependent relationship was found between the aphelinid Aspidiotiphagus sp., the dominant parasite of this scale insect, and the minimum temperature.
