Geographic range extension of hop cyst nematode, Heterodera humuli, from Tasmania to the Australian mainland

Abstract Hop cyst nematode, Heterodera humuli Filipjev, 1934 was found in soil samples collected from hop farms Bushy Park, Tasmania and Merriang, Victoria, Australia. Morphological molecular characteristics were consistent with those described for this species other parts of the world. Novel gene sequences ITS rRNA, 28S rRNA CO1 mtDNA generated cysts compared against H. available on NCBI GenBank database, demonstrating little to no genetic variation between Australian nematode populations regions. This report provides first sequence data Australia reports a significant range extension mainland.
