Distribution details in Canada
Current pest situation evaluated by EPPO on the basis of information dated
2022: Present, few occurrences
Pest status declared by NPPO: Absent, invalid record (2012)
Pest status declared by NPPO: Absent, invalid record (2012)
EPPO Reporting Service (2009/089)
EPPO Reporting Service (2012/100) : the NPPO of Canada officially declared that 'Ca. L. psyllaurous' has never been detected in Canada on tomato or potato. This record in Alberta (probably based on Carter 1939, then quoted by Crawnshaw 1993) most probably related to psyllid yellows only. Although the psyllid vector (Bactericera cockerelli) occurs occasionally in several Canadian provinces under glasshouse, it is not considered to be able to overwinter outdoors and establish in Canada.
EPPO Reporting Service (2019/100) : found in one potato tuber in Alberta
EPPO Reporting Service (2022/113) : associated with ash decline in Alberta, Manitoba, Saskatchewan.
