Characterization Of The Microbial Associates Of Nematodes Pathogenic To Myrmica Rubra, Jonathan E. Dumont

Honors College

Pristionchus entomophagus is a necromenic nematode commonly associated with dung beetles (Geotrupes spp.) in Europe. Recently, it has been found in Maine emerging from cadavers of M. rubra, an ant native to Europe that is currently established and pestiferous in Maine (Groden and Stack 2011). Laboratory assays inoculating M. rubra with these nematodes caused significant mortality. This study aimed to characterize the bacterial associates of P. entomophagus in order to further understand its pathogenic relationship with M. rubra. Bacterial samples were collected from the cuticle and gut of the nematodes, and the hemolymph of infected hosts. Single spore isolates were …
