Notes: Title in English: [Comparison of the biological cycles of the Diaspids Parlatoria pergandii, Aonidiella aurantii and Lepidosaphes beckii (Homoptera, Diaspididae) in citrus.] Abstract: A naval orange orchard was sampled for one year to compare the recently designated pest species, Aonidiella aurantii (California Red Scale) with Lepidosaphes beckii and Parlatoria pergandii; the proportion of immatures was very high in A. aurantii populations; development of the generations can be faster on fruits than on leaves.
