Abstract

A novel circular single-stranded DNA (ssDNA) virus, volvovirus, from the house cricket has been described recently. Here, we report the isolation of volvoviruses from Acheta domesticus in Japan and Gryllus assimilis in the United States. These Acheta domesticus volvovirus (AdVVV) isolates have genomes of 2,517 and 2,516 nucleotides (nt) and 4 large open reading frames (ORFs).

Highlights

  • A novel circular single-stranded DNA virus, volvovirus, from the house cricket has been described recently

  • Since September 2009, stocks of the preferred house cricket, Acheta domesticus, were decimated due to severe fatal outbreaks caused by a densovirus, the Acheta domesticus densovirus (AdDNV) [2, 3]

  • Some recent samples contained a new single-stranded, circular DNA virus [4], volvovirus or Acheta domesticus volvovirus (AdVVV)-IAF, that is not related to cycloviruses [5, 6], circoviruses [7, 8, 9], nanoviruses [10, 11], or geminiviruses [12, 13, 14]

Summary

Introduction

A novel circular single-stranded DNA (ssDNA) virus, volvovirus, from the house cricket has been described recently. Billions of pet-feeder crickets are produced annually [1, 2]. Since September 2009, stocks of the preferred house cricket, Acheta domesticus, were decimated due to severe fatal outbreaks caused by a densovirus, the Acheta domesticus densovirus (AdDNV) [2, 3]. In Japan house cricket stocks were decimated since early in the summer of 2009 despite strict import and export regulations.
