Recent discovery of widespread Ixodes affinis (Acari: Ixodidae) distribution in North Carolina with implications for Lyme disease studies.

Ixodes affinis, which is similar morphologically to Ixodes scapularis, is widely distributed in North Carolina. Collections have documented this species in 32 of 41 coastal plain counties, but no piedmont or mountain counties. This coastal plain distribution is similar to its distribution in Georgia and South Carolina, where it is considered an enzootic vector of Borrelia burgdorferi sensu stricto. An updated list of hosts for I. affinis in the U.S.A. is included, increasing the number to 15 mammal and one bird species. The presence of questing adults of I. affinis from April to November reinforces the need for confirmed identifications of suspected tick vectors of Borrelia spirochetes collected during warm months.

Three new mosquito records for North Carolina.

Recently enhanced mosquito surveillance programs in northeastern North Carolina have resulted in the collection of Ochlerotatus aurifer, Oc. cantator, and Oc. grossbecki. These specimens represent the 1st confirmed North Carolina records of these species. Collection-site and species distribution data are included.
