| size variation of trichospores of harpella melusinae in larval black flies. | trichospores of harpella melusinae in larval black flies from four streams in northwestern south carolina were measured. the longest fresh trichospore was 242 microm, 38% longer than the reported maximum length of trichospores for this species. after staining with lactophenol cotton blue, trichospore length was significantly reduced by up to 24.4% in fresh larvae and up to 4.9% in fixed larvae. mean trichospore length differed significantly between seasons and between sampling sites but did not ... | 2007 | 17883026 |
