Toxoptera citricidus in Spain and Portugal
In Portugal, Toxoptera citricidus (Homoptera: Aphididae – EPPO A1 list) was first reported in 1994 on the island of Madeira (EPPO RS 95/007) and then from the mainland in 2004 (EPPO RS 2004/130). A short communication from Ilharco et al. (2005) provides more details on this finding in mainland Portugal and also in nearby Spain. T. citricidus was first collected in a yellow water trap in August 2002 at Tapia de Casariego (coastal area in Asturias, Spain) and in November 2003 on Citrus deliciosa at Arões in the North of Portugal. In Spain, the aphid was later found in several other localities in Asturias (Arbón, Argüelles, Villaviciosa) and Galicia (Vigo). In the North of Portugal, the pest was detected in several localities (Monção, Valença, Vila Verde, Amares, Barcelos, Braga, Vila Nova de Famalicão, Guimarães, Santo Tirso, Felgueiras, Celorico de Basto, Amarante, Penafiel, Marco de Canavezes and Santa Marta de Penaguião).
