Tests to control Ceratitis capitata (Wiedemann) in organic peach, orange and clementine orchards.The Mediterranean Fruit Fly, Ceratitis capitata (Wiedemann), is considered the key pest of several fruit species in organicfarming. Experiments for the control of this pest have been carried out in organic peach orchards (in 2009 on amedium-late ripening cultivar, ‘Bella di Bivona’; in 2011 on a very early ripening one, ‘San Pedro’) testing nets, spinosadand pyrethrum (year 2009), in orange citrus groves (cv. Navelina, early ripening period), comparing spinosad, kaolin andbentonite (years 2009 and 2010) and in a clementine grove (cv. Monreal), using kaolin and bentonite. The very early ripeningcultivars anticipate medfly presence in the field and avoid its attack; when adults of C. capitata are present the onlyeffective method to protect peach production resulted the coverage with nets, as none of tested products obtained significantdifferences in infestation levels in comparison with untreated control. Spinosad resulted not effective also in the orangegrove, while kaolin and bentonite limited the pest attack both on orange and clementine; results can be consideredsatisfactory for kaolin, while the two bentonite products used in the trials showed some differences probably due to theirmicronization degree.
