Occurrence of a mermithid nematode parasite of Carpophilus lugubris (Coleoptera: Nitidulidae) in central Illinois
Environmental Entomology 24 (5), 1245-1251
Abstract: A mermithid nematode parasite (probably a new species of Hexamermis) was encountered in adult dusky sap beetles, Carpophilus lugubris Murray, collected in April and May in central Illinois during 1991-1994. Nematodes emerged from as many as 42% of live C. lugubris collected from traps. Dissections indicated infection rates up to 89%. Most nematodes emerged 7-10 d after insects were collected. The nematode was found at only 1 site (in Mason County) of 3 (in different counties) surveyed in 1991 and 1992, and at only the Mason County site of 19 sites surveyed in 5 counties in 1993. Distribution of nematode-infected dusky sap beetles at the Mason County site in 1994 was fairly uniform around the perimeter of oak woodlands bordering 16.2 ha of corn and soybean fields.
