Nematode-host
Guides
Drosophila putrida
A temperate North American fruit fly in the Drosophila testacea species group, distinguished by its obligate association with mushrooms as both feeding and breeding substrate. The species is notable for its tolerance of potent mycotoxins, including α-amanitin, and serves as a host for the nematode parasite Howardula aoronymphium. Despite this parasitism, studies have found no evidence of behavioral adaptations to avoid infection or reduce parasite virulence.
Ischnoptera
Narrow-winged Cockroaches
Ischnoptera is a genus of small to medium-sized cockroaches in the family Ectobiidae, commonly known as Narrow-winged Cockroaches. The genus contains approximately 98 species distributed primarily in the Americas, with records from the United States through Mexico, Central America, and South America including Argentina and Brazil. Members of this genus are primarily ground-dwelling forest cockroaches. At least one species, Ischnoptera deropeltiformis, has been documented as a host for specialized pinworm nematodes in the hindgut.
Ischnoptera deropeltiformis
Dark Wood Cockroach, Dark Wood Roach
Ischnoptera deropeltiformis, commonly known as the dark wood cockroach, is a species of wood cockroach in the family Ectobiidae. It is native to the United States and has been recorded as a host for the pinworm nematode Protrellus browni. The species is part of the diverse wood cockroach fauna associated with forest floor habitats.
Neocurtilla
northern mole crickets
Neocurtilla is a genus of mole crickets in the family Gryllotalpidae, comprising approximately seven described species distributed primarily in North, Central, and South America. Species within this genus are fossorial insects adapted for burrowing, with enlarged forelegs modified for digging. The genus includes notable species such as Neocurtilla hexadactyla, commonly known as the northern mole cricket, which has been studied for its unique chromosome segregation mechanisms. Members of this genus are of interest in agricultural contexts due to their potential as pests and their associations with natural pathogens.
Trachelipus rathkii
Rathke's Woodlouse
Trachelipus rathkii is a medium-sized European woodlouse introduced to North America, where it has established populations across the northern United States and southern Canada. It is distinguished by its tolerance for flooding and poorly drained habitats, often dominating riverside and floodplain communities. The species serves as a documented host for the nematode Caenorhabditis remanei, which associates with it as dauer larvae on its dorsal plates and ventral appendages.
