Abstract

The caddisflies of Mount Rainier National Park (MRNP), Washington, USA, were surveyed between 1997 and 2004. At least 1,930 specimens from over 250 collections at 163 sites were examined. Based on the current understanding of caddisfly systematics, 108 species were identified. With nine additional species previously reported that we did not confirm, a total of 117 species are now known from MRNP, representing over 50 % of the reported Washington state caddisfly fauna. The collections of the rare brachycentrid, Eobrachycentrus gelidae Wiggins, represent the second and third known records of adults for this species. Six species, Apatania zonella (Zetterstedt), Asynarchus aldinus (Ross), Limnephilus moestus Banks, Polycentropus flavus (Banks), Rhyacophila vobara Milne, and Neophylax occidentis Banks represent new records for the state of Washington. One new species of Polycentropus was discovered.

A revised annotated checklist of the Chironomidae (Insecta: Diptera) of the southeastern United States

A revised annotated checklist for the chironomid midges (Diptera: Chironomidae) of the southeastern United States is presented that includes the states of Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee. Much of the information concerns occurrence and habitat preference records based upon the authors' data, as well as published and unpublished data. Some information is also presented that includes aspects of biology, habitat preference, bibliographic sources, and nomenclatorial changes. Based upon the present work, the chironomid fauna of the southeastern states is comprised of 189 genera (172 described, 17 informally or unofficially described) and 754 species (505 described, 17 informally or unofficially described, 33 that are assumed for generic or subgeneric presence only, 197 estimated species, and 2 species groups). Several new species synonyms and generic placements are recognized. Thirty-eight genera known from the Nearctic region remain unknown from the southeastern states. Diversity of species was greatest in the subfamily Chironominae, considering named as well as unnamed and estimated species. There were no significant changes in overall regional distribution patterns of subfamilies or habitat preferences form that which has been previously reported. The greatest totals for regional records, habitat types, and state occurrences were the Coastal Plain (378), streams (271), and North Carolina (373), respectively.

Columnaris as a disease of cold-water fishes

A natural outbreak of columnaris disease among wild adult and hatchery-reared fingerling salmon in the State of Washington is described. The disease is identified by the recovery of the causative organism, Bacillus columnaris Davis, which may be readily identified by its characteristic action in forming columns on the surfaces of infected material held in a water mount on a microscope slide. The gross lesions vary in appearance according to the particular organ affected but are formed, essentially, by the progressive necrosis and disintegration of the tissues. The tissues primarily affected are skin, body musculature, and the gills. Cultivation of the causative organism in tryptone solutions is recorded. Controlled, laboratory-induced infections indicate that among the cold-water fishes, columnaris disease is of little consequence to fingerlings at water temperatures below 55° F., but becomes highly pathogenic at temperatures in excess of 70° F. Between these temperature thresholds, the degree and severity of the infection is markedly influenced by factors adverse to the host. No effective control measures have been found.
