Zmienność genetyczna, specyficzność żywicielska i zdolność do przenoszenia wirusa mozaiki smugowatej pszenicy (WSMV) w obrębie kompleksu gatunków Aceria tosichella

Wiktoria Szydło

Abstract

Wheat curl mite (WCM), Aceria tosichella (Acariformes: Eriophyoidea), is a high-concern pest species, due to its’ wide host range which includes wheat, worldwide distribution and ability to transmit Wheat streak mosaic virus (WSMV) and at least three other plant viruses. Lately, the vast genetic variation among WCM populations was noticed, which led to the discovery that WCM is actually a complex of genetic lineages with diverse ecological features (biotypes) and may even represent a set of cryptic species. The aim of the study was to analyze the host specificity, genetic variation and WSMV vectoring abilities of WCM complex. Specifically, three study areas were explored: 1) WCM infestation parameters on host plants, 2) genetic variation of WCM populations based on mitochondrial and nuclear markers, 3) WCM and WSMV co-occurrence and the ability of wheat-associated WCM lineages to transmit WSMV. The results confirmed differential host plant species utilization by WCM and revealed more than twenty genetic lineages of these mites. Genetic variation of the lineages reached the interspecific level. The lineages were characterized by different host specificity levels, some of them being monophagous and some polyphagous. The WSMV vectoring abilities of two invasive lineages of WCM distributed worldwide on wheat MT-1 and MT-8, were demonstrated.
