This is the third meeting after the new period of activity of the group started in 2002 with the first meeting in Valencia, followed by Lisbon in 2005. The meeting was held at the excellent facilities provided by the Università degli Study di Catania. This third meeting experienced a considerable increase in the number of assistants and presentations. In all, there were 139 participants from 19 countries, presenting 103 communications (37 orals and 66 posters). This represents a notable increase compared to the two previous meetings of Lisbon 2005 (100 participants) and Valencia 2002 (60 participants). The number of participants per country was as follows: Italy (56), Spain (38), Morocco (5), Israel (4), Turkey (4), Portugal (3), Algeria (3), Irak (2), Iran (2), Montenegro (2), Tunisia (2), Belgium (1), Brazil (1), France (1), Ghana (1), Greece (1), Switzerland (1), United Kingdom (1) and United States (1). The two most represented pests were the Citrus Red Scale, Aonidiella aurantii, with 20 communications, and the Medfly (Ceratitis capitata) with 17, followed by the Citrus leafminer Phyllocnistis citrella and the red spider mite Tetranychus urticae, with 7 presentations each. Citrus diseases, included in a special session on citrus diseases, showed a substantial increase compared with previous meetings, with 10 presentations. Among other topics, there was ample discussion on emerging problems of recently introduced new pests, like Pezothrips kellyanus and Toxoptera citricida, as well as on possible introductions of new diseases like the Citrus canker, transmitted by citrus the leafminer, Citrus tristeza virus, transmitted by Toxoptera citricida, and especially HuangLonBin (Citrus Greening), transmitted by psyllids. Overall, the meeting was very well organized and very successful due to high number of participants and the interest of the matters presented. The objectives for next meetings would be to maintain the participation, to attract more researchers that are working in Citrus pests and diseases in the Mediterranean area, and to keep broadening the spectrum of activities of the group. The group has been traditionally a meeting place for entomologists, but has poor tradition in plant pathology. In my opinion the three main challenges for the group are to encourage cooperation within members of the WG in methodology or research projects, stimulate discussion in the meetings and at the mailing list, and to support and encourage the participation of young scientists from Southern Mediterranean countries. The local organizer of the meeting was Gaetano Siscaro, from the Università degli Studi di Catania. He and his collaborators of the organizing committee developed an extraordinary task of organization and arrangements before and during the meeting. On behalf of all the participants I would like to express our gratitude to all of them for the very pleasant stage and for the attentions we received in Catania. I would like also to express my special thanks to the liaison officer of the group, Mohamed Besri, for his support and help in the management of the group, and for his contribution to the success of the meeting. I look forward to see all of you at our next meeting in Agadir (Morocco), in 2010. Valencia, April 2008 F.
