First report of Oligonychus perseae in Morocco

In Morocco, Oligonychus perseae (Acari: Tetranychidae – formerly EPPO Alert List) was first found in 2018. From September to November 2018, damage was observed in several avocado (Persea americana) orchards near Mnasra (Kénitra province, Rabat-Salé-Kénitra region) and Laouamra (Larache province, Tanger-Tétouan region). In Morocco, O. perseae is considered to be an emerging and primary pest on avocado. Surveys will be carried out to determine its distribution, and studies will be conducted on possible measures to prevent its further spread.
