Quadraspidiotus perniciosus does not occur in Poland
In PQR, the record of Quadraspidiotus perniciosus (Hemiptera: Diaspididae – EPPO A2 List) in Poland was based on an English abstract of a paper written in Polish (Łagowska ; Golan, 1998) which said that Q. perniciosus was found during a survey for scale insects carried out in 1990/1994. The NPPO of Poland recently informed the EPPO Secretariat that this abstract had misinterpreted the text of the paper and officially confirmed that Q.;perniciosus does not occur in Poland. In the text of the full paper, Q. perniciosus was simply mentioned as one of the scale species for which presence had been recorded in the past. Indeed, literature data says that Q. perniciosus was detected in Poland in 1948-49 in a few places near Wadowice but it was then successfully eradicated (Głowaciński et al., 2011). Most importantly, annual surveys (including laboratory testing) have been carried out in Poland by the State Plant Health and Seed Inspection Service in orchards, nurseries and packing places since 2009. During these surveys, Q. perniciosus has never been detected.
The pest status of Quadraspidiotus perniciosus in Poland is officially declared as: Absent, pest no longer present.
