Abstract
In September 2020, several plants of fowl bluegrass, Poa palustris with seed galls were collected on a bank of river in Teton County, Wyoming, USA. Isolated nematodes were identified by both morphological and molecular methods as Anguina agrostis. This is a first report of A. agrostis in Wyoming and its report on fowl bluegrass.
Highlights
The bent grass seed gall nematode, Anguina agrostis (Steinbuch, 1799) Filipjev, 1936 was described from Agrostis capillaris collected in Bavaria, Germany
Analysis of the ITS rRNA gene sequences made by Subbotin et al (2004) supported the concept of a narrow specialization of seed gall nematodes and showed that A. agrostis was only found on Agrostis capillaris
New sequences were deposited in the GenBank database under accession numbers: MW165338 (ITS1-5.8S-ITS2 rRNA gene) and MW174765 (COI gene)
Summary
The bent grass seed gall nematode, Anguina agrostis (Steinbuch, 1799) Filipjev, 1936 was described from Agrostis capillaris collected in Bavaria, Germany. Many grass species have been included in the list of host plants for this nematode. Southey (1973) and Southey et al (1990), after reviewing literature on the host specificity of seed gall nematode populations and their morphological and morphometric differences from the type host, suggested that a thorough revision of species causing galls in the flowers of grasses was required.
