First report of Phyllocnistis citrella in France (Corse, Réunion) and Mauritius
The citrus leaf miner, Phyllocnistis citrella (potential EPPO A2 quarantine pest) has been found for the first time in 1995-02, on the island of Réunion (FR). A survey has immediately been set up and has shown that the pest was already widespread in citrus groves. It could be found from sea level up to an altitude of 1250 m. Due to the very rapid spread of the citrus leaf miner, eradication was not felt practical. In their paper, the authors reviewed the biology and the geographical distribution of P. citrella throughout the world. In particular, it can be noted that the citrus leaf miner is now present in Corsica (FR), and has recently been introduced into Mauritius (at the end of 1995-03). Considering the rather simultaneous introduction in Réunion and Mauritius, it is suggested that the insect could have been transported by the wind from Asia. In Réunion, studies will be carried out on its potential natural enemies (already present on the island or to be introduced) and on chemical control methods, in order to implement IPM programmes.
The occurrence of P. citrella in Réunion, Mauritius and Corsica are new records for the EPPO Secretariat.
