| Occurrence and prevalence of seven bee viruses in Apis mellifera and Apis cerana apiaries in China. | Populations of Apis mellifera and Apis cerana in China were surveyed for seven bee viruses: acute bee paralysis virus (ABPV), black queen cell virus (BQCV), chronic bee paralysis virus (CBPV), deformed wing virus (DWV), Kashmir bee virus (KBV), sacbrood virus (SBV), and Isreal acute paralysis virus (IAPV). No KBV was detected from any samples of the two species. In A. mellifera, DWV was the most prevalent virus, but in A. cerana, SBV was the dominant. Simultaneous multiple infections of viruses ... | 2012 | 22062807 |
| prevalence of honeybee viruses in different regions of china and argentina. | honeybees are threatened by various pathogens and parasites. more than 18 viruses have been described in honeybees and many of them have been detected in china and argentina. in china, both apis cerana and apis mellifera are raised. in argentina, beekeepers raise different ecotypes of a. mellifera: european honeybees (in both temperate and subtropical regions) and africanised honeybees (in subtropical areas only). a thorough study was carried out in both china and argentina to analyse the curren ... | 2016 | 28332647 |
| molecular and phylogenetic characterization of honey bee viruses, nosema microsporidia, protozoan parasites, and parasitic mites in china. | china has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in chinese apiaries. we thus conducted a molecular survey of honey bee rna viruses, nosema microsporidia, protozoan parasites, and tracheal mites associated with nonnative apis mellifera ligustica and native apis cerana cerana colonies in china. we found the presence of ... | 2013 | 23467539 |
| prevalence and distribution of six bee viruses in korean apis cerana populations. | the prevalence and distribution of six bee viruses was investigated in 527 apis cerana samples which were collected from five provinces in south korea. the most prevalent virus, black queen cell virus (bqcv), was present in 75.11% of 446 adult bee samples, followed by sacbrood virus (sbv) in 30.71%. deformed wing virus (dwv), kashmir bee virus (kbv), and chronic bee paralysis virus (cbpv) were present at lower levels of 8.07%, 1.56%, and 0.44%, respectively. the most prevalent virus in 81 larvae ... | 2012 | 22273697 |
| molecular identification of chronic bee paralysis virus infection in apis mellifera colonies in japan. | chronic bee paralysis virus (cbpv) infection causes chronic paralysis and loss of workers in honey bee colonies around the world. although cbpv shows a worldwide distribution, it had not been molecularly detected in japan. our investigation of apis mellifera and apis cerana japonica colonies with rt-pcr has revealed cbpv infection in a. mellifera but not a. c. japonica colonies in japan. the prevalence of cbpv is low compared with that of other viruses: deformed wing virus (dwv), black queen cel ... | 2012 | 22852042 |
