Eotetranychus lewisi eradicated from German poinsettia greenhouses

In Germany, Eotetranychus lewisi (Acari: Tetranychidae - EU Annexes) was first reported in August 2020 in 2 nurseries producing poinsettias (Euphorbia pulcherrima) in greenhouses in Schleswig-Holstein.

The NPPO conducted trace-back studies and initiated an awareness campaign for producers. As a result, further outbreaks were identified on poinsettias in other greenhouses: one in Berlin (October 2020), one in Brandenburg (October 2020), two in Hessen (November and December 2020), one in Rheinland-Pfalz (December 2020), and one in Sachsen (November 2020).

In all cases, official phytosanitary measures were taken, including acaricide treatments, destruction of infested plants, prevention of movement of plants, thorough cleaning of the greenhouses. As of July 2021, all outbreaks were considered eradicated. The pest status of Eotetranychus lewisi in Germany is officially declared as Absent, pest
eradicated.
