Is there a mistake here?  I have not heard of a Papua New Guinea (PNG) 
strain of Varroa destructor (VD).  There is V. jacobsoni in PNG.  In the 
introduction in the paper it quotes two references of this strain -
Papua New Guinea (PNG) (de Guzman et al., 1997; Anderson and Fuchs, 1998).

As VD was not described by Anderson until 1999, he presented his findings at 
Apimondia in Vancouver, a PNG strain of VD in 1997 and 1998 is not possible.
