EPPO Global Database

Diabrotica undecimpunctata undecimpunctata(DIABUN)

Distribution details in Guam

Current pest situation evaluated by EPPO on the basis of information dated 2021: Absent, unreliable record
First recorded in: 2013
EPPO Reporting Service (2014/034) : a single specimen was collected from lettuce growing at a farm in Mangilao in June 2013.

While revising the EPPO datasheet on this pest in 2021, it was noticed that the record of Moore and Bamba (2014) is incomplete as it does not mention the subspecies. This record is thus considered as doubtful.
