Situation of Aonidiella citrina in Italy
As reported in EPPO RS 95/035, a small outbreak of Aonidiella citrina (Homoptera: Diaspididae – EU Annexes) was found in 1994, in Calabria, Italy. Surveys and observations were made in citrus groves in 1995-1996 and in 1999-2000, in Calabria and Sicilia. 10 years after its first report, A. citrina is still confined to a limited area of the Sibari Plain in Calabria. It was not found in Sicilia. Biological observations showed that, in Calabria, A. citrina completes 3 generations per year, with peaks of crawlers in the first half of June, beginning of August and beginning of September. During winter, various stages can be observed (mainly the second instar). In March, mortality reached 65% due to abiotic and biotic factors, and in particular due to the activity of Aphytis melinus and Encarsia citrina. The situation of Aonidiella citrina ;in Italy can be described as follows: Present, found in a limited area of the Sibari Plain in Calabria.
