First finding of Toxoptera citricida in mainland Portugal
Toxoptera citricida (Homoptera: Aphididae - EPPO A1 list) was detected in isolated citrus plants in the north-west of Portugal (Entre-Douro e Minho region). This is the first finding of T. citricida in mainland Portugal. A delimiting survey has immediately been set up and eradication measures applied (phytosanitary treatments and prohibition of movements of citrus plant material). The origin of this infestation remains unknown for the moment, but is being investigated.
EPPO note: It can be recalled that T. citricida, which is an efficient vector of Citrus tristeza closterovirus, was found for the first time in 1994 on the island of Madeira (PT) where it is subject to an eradication programme.
