title: Prevalence and intensity of Cephalobium microbivorum (Nematoda: Diplogasterida) infection in three species of Gryllus field crickets.
abstract: Here we report on the results of a survey for nematode parasites in three species of field cricket, Gryllus integer, Gryllus lineaticeps, and an undescribed Gryllus species. The nematode, Cephalobium microbivorum, was recovered from the intestine of the crickets. To our knowledge, this paper is just one of two to report on the biology of C. microbivorum. This nematode was first described from the cricket, Gryllus assimilis. It has not been documented in any other Gryllus species to date. G. integer were collected from two locations: Aguila, Arizona and Davis, California. G. lineaticeps were collected from Davis, CA and an undescribed species of Gryllus cricket was collected from Aguila, AZ. Results of the survey revealed the presence of nematodes in all three species of Gryllus, at all collection sites. The intensity of infection ranged from 1 to 113 nematodes.
