| infectivity of resting spores of massospora cicadina (entomophthorales: entomophthoraceae), an entomopathogenic fungus of periodical cicadas (magicicada spp.) (homoptera: cicadidae). | massospora cicadina peck is a fungal pathogen of 13- and 17-year periodical cicadas (magicicada spp.). in northwest arkansas, during the spring 1998 emergence of the 13-year periodical cicada, magicicada tredecassini (brood xix), <1% of emerging cicadas were infected with the conidial stage of m. cicadina, similar to data collected from the same population in 1985. however, in northwest arkansas plots treated with m. cicadina resting spores collected from infected 17-year magicicada septendecim ... | 2002 | 12234535 |
| independent divergence of 13- and 17-y life cycles among three periodical cicada lineages. | the evolution of 13- and 17-y periodical cicadas (magicicada) is enigmatic because at any given location, up to three distinct species groups (decim, cassini, decula) with synchronized life cycles are involved. each species group is divided into one 13- and one 17-y species with the exception of the decim group, which contains two 13-y species-13-y species are magicicada tredecim, magicicada neotredecim, magicicada tredecassini, and magicicada tredecula; and 17-y species are magicicada septendec ... | 2013 | 23509294 |
