Neohaematopinus sciuri Jancke


Neohaematopinus sciuri Jancke 

Ex Sciurus carolinensis  (gray squirrel): 1 F, TN, Cocke Co., Cosby, 29 May 2001, W. K. Reeves, L­ 2979.

In eastern North America, this louse is a host specific parasite of the gray squirrel ( Kim et al. 1986, Durden & Musser 1994). Durden (1980) found this louse to be abundant on S. carolinensis  in central Tennessee but the above record is the first one for the GSMNP. Several genotypes of undescribed Bartonella  have been isolated from this louse (Durden et al. 2004).

Neohaematopinus sciuropteri (Osborn) 

Ex Glaucomys volans  (southern flying squirrel): 3 M, 5 F, 4 N, NC, Haywood Co., Purchase Knob, 20 Oct. 2002, K. Walters, L­ 3036.

This louse is widely distributed in North America as an ectoparasite of both the northern and southern flying squirrel ( Kim et al. 1986, Durden & Musser 1994) but the above record is the first for both North Carolina  and the Park. Neohaematopinus sciuropteri  might be involved with the enzootic transmission of Rickettsia prowazekii  ( Sonenshine et al 1978).

Neohaematopinus semifasciatus Ferris 

Ex Tamiasciurus hudsonicus  (red squirrel): TN, Sevier Co., Greenbrier, 2 Apr. 1931, R. L. Boke ( Durden et al. 1997 a); 1 F, TN, Sevier Co., Clingman’s Dome, 17 Jul. 2001, K. Walters, L­ 3009.

The primary hosts of this louse are Tamiasciurus douglasii  and T. hudsonicus  in North America; but it is known to infest several other species of tree squirrels in Panama and Venezuela ( Durden & Musser 1994). Polyplax auricularis Kellogg & Ferris 

Ex Peromyscus maniculatus  (deer mouse): 1 N, NC, Haywood Co., Purchase Knob, 20 Oct. 2002, K. Walters, L­ 3047; 1 F, TN, Sevier Co., Walker Prong, 15 Jun. 1953, R. Traub & D. Pfitzer ( Durden et al. 1997 a); 1 M, TN, Sevier Co., Brushy Mount, 7 Apr. 2002, K. Walters, L­ 3006.

This louse is a widespread ectoparasite of sigmodontine rodents (some species of Onychomys  , Peromyscus  and Reithrodontomys  ) in North and Central America ( Durden & Musser 1994). Polyplax auricularis  appears to be more common in northern latitudes or at higher elevations in southern latitudes. Polyplax serrata (Burmeister)  —house mouse louse

Ex Mus musculus  (house mouse): 1 N, TN, Blount Co., Elkmont, 6 Jul. 1937, R.D.V.

The house mouse louse has a cosmopolitan distribution as an ectoparasite of M. musculus  . Polyplax serrata  is a mechanical vector for the bacterium, Eperythrozoon coccoides ( Berkenkamp & Wescott 1988)  . Polyplax spinulosa (Burmeister)  —spined rat louse

Ex Rattus norvegicus  ( Norway rat): 3 F, TN, Sevier Co., Little River Rd., 0.8 miles West of Elkmont turnoff, 27 Dec. 2003, K. Langdon, L­ 3285.

The spined rat louse parasitizes domestic rats ( Rattus  spp.) throughout the world ( Durden & Musser 1994) but this is the first record of it from the Park. This louse is vector of Rickettsia typhi  and Haemobartonella muris  (Durden 2002, Roberts & Janovy 2000) and might be a vector of “ Bartonella rattimassiliensis  ” to rats ( Reeves et al 2006 a).
