Occurrence of Nosema oryzaephili in Cryptolestes ferrugineus and transfer to the genus Paranosema
A microsporidium that closely resembles Paranosema species at the level of the light microscope was isolated from the rusty grain beetle, Cryptolestes ferrugineus. It’s identity as Nosema oryzaephili (originally described from Oryzaephilus surinamensis) was confirmed by comparison with a known isolate of N. oryzaephili based on spore size, small subunit rDNA sequence, and relative infectivity to O. surinamensis, Tribolium castaneum, and Ephestia kuehniella. Phylogenetic analysis of the small subunit rDNA indicates clearly that this species belongs in the genus Paranosema and thus the designation Paranosema oryzaephili (Burges, Canning and Hurst) is proposed. In spite of the abundance, economic importance, and world-wide distribution of C. ferrugineus, this is the first report of a microsporidial infection in this species. This is also the first report of P. oryzaephili in the new world.
