Notes: [Conference also sponsored by the Accademia Nazionale Italiana di Entomologia Palermo - Erice - Bagheria, 28 May -1 June 1985.] Aspidiotus nerii on lemon was successfully controlled in orchards sprayed only once a year in Sicily by the ectophagous Aphytis chilensis and the endophagous Encarsia citrina [Aspidiotiphagus citrinus]. In 1981, these aphelinids together gave up to 44.45% parasitism in the winter and up to 48.59% in the summer, while in 1982 they gave up to 29.44% in the winter and up to 18.96% in the summer; Aphytis chilensis was more active in the summer and Aspidiotiphagus citrinus in the winter.
