Cyst nematodes of the genus comprise 87 nominal species of economically important plant parasites, with the group one of the largest, consisting of 12 species. Samplings for cyst nematode studies were carried out from multiple locations in Greece from 2013 to 2021. Cysts of the genus were recovered from potato fields, athletic stadium turfgrass and a garlic field. The recovered populations were identified using sequences of 28S, ITS1 and ITS2 rRNA, mitochondrial COI, and nuclear Hsp90. Using integrative taxonomic approaches, the recovered isolates were identified as (from potato fields and turfgrass), (from potato fields) and (from a garlic field), representing new records for Greece. Population diversity within each species was investigated using statistical parsimony of ITS rRNA and mtCOI, revealing haplotypes of the Greek populations and their relationships to others found in the Mediterranean basin and worldwide.
该属的孢囊线虫包括87个具有经济重要性的植物寄生名义种，其中该类群是最大的类群之一，由12个种组成。2013年至2021年期间，在希腊的多个地点进行了孢囊线虫研究的采样。从马铃薯田、体育场草坪草和大蒜田中采集到了该属的孢囊。利用28S、ITS1和ITS2 rRNA、线粒体COI和核Hsp90的序列对采集到的群体进行了鉴定。采用综合分类学方法，将采集到的分离株鉴定为（来自马铃薯田和草坪草）、（来自马铃薯田）和（来自大蒜田），这代表了希腊的新记录。利用ITS rRNA和mtCOI的统计简约法研究了每个物种内的群体多样性，揭示了希腊群体的单倍型及其与在地中海盆地和世界各地发现的其他群体的关系。
