Field detection of X-disease mycoplasmalike organism in Paraphlepsius irroratus (Say) (Homoptera: Cicadellidae) using a DNA probe
Environmental Entomology 21 (1), 81-88
Abstract: The seasonal and geographic distribution of X-diseased Paraphlepsius irroratus (Say) was studied in south, central, and northwest Michigan in 1988 and 1989 using a DNA probe. C6c, a fragment of pWX1 derived from infected Colladonus montanus (Van Duzee), detected eastern X-disease in diseased P. irroratus. Maximum numbers of infected leafhoppers were detected at the beginning of the emergence of each generation in early June and in late September, In early summer the percentage of X-diseased leafhoppers at the various sites ranged from 12.2 to 43.3%, and in the late season from 3.3 to 36.4%. The X-diseased leafhoppers occurred only in south and central Michigan.
