Ditylenchus destructor(DITYDE)

Distribution details in Australia (Tasmania)

Current pest situation evaluated by EPPO on the basis of information dated 2011: Absent, pest no longer present
From NPPO: Absent, pest no longer present
Thistlethwayte (1961) was the primary source of the record of D. destructor in Tasmania which was later mentioned in other publications (Khair, 1981; McLeod et al., 1994, Sampson & Walker, 1982). The nematode was detected in a single small patch on a farm at Tunnack (Southern Tasmania), an area where potatoes are no longer grown. As no other records of D. destructor have been made in Tasmania since 1961, it was supposed that it was a misidentification of D. dipsaci (NPPO, 2008 – see EPPO EPPO Reporting Service (2008/106) ) but recent investigations confirmed that this single record was valid.
Nevertheless, surveys done in Tasmania on potatoes or other host plants never detected D. destructor again (annual surveys are conducted since 1992). The NPPO of Australia concluded that the status of D. destructor in Tasmania is: ‘Absent, no longer present’ (NPPO, 2011).
