克什米尔蜜蜂病毒(Kashmir bee virus, KBV)作为一种毒力较强的蜜蜂急性病毒,自20世纪70年代被分离鉴定以来,已发现其广泛侵染世界各地的东方蜜蜂Apis cerana和西方蜜蜂Apis mellifera。KBV在蜂群内通过垂直和水平两种方式进行传播,且狄斯瓦螨Varroa destructor在其中扮演着重要角色,这使得KBV的分布范围持续扩散。目前已报道的病毒宿主除蜜蜂外,其还可侵染熊蜂、胡蜂等多种野生授粉昆虫。同时,KBV作为一种典型的双顺反子病毒科病毒,由于其在分子生物学上与同科的蜜蜂急性麻痹病毒(acute bee paralysis virus, ABPV)和以色列急性麻痹病毒(Israeli acute paralysis virus, IAPV)间的高相似性,对该病毒流行性的调查与检测、分类等研究的混乱局面也接踵而至。本文对过去40多年来的KBV相关研究进行综述,以期为KBV及类似昆虫病毒的后续研究提供一定的参考和借鉴,促进养蜂业的健康发展。 相似文献

The prevalence of pathogens in honey bee (Apis mellifera) colonies infested with the parasitic mite Varroa jacobsoni 总被引:2,自引:0,他引:2
The prevalence of nine honey bee viruses in samples of dead adult bees from Apis mellifera colonies in the Netherlands and Germany infested with the parasitic mite Varroa jacobsoni was compared with virus incidence in uninfested colonies in Britain. In colonies with low mite populations the viruses present and their incidence during the year were similar to the results obtained from British colonies. However, in marked contrast with findings in Britain, acute paralysis virus (APV) was the primary cause of adult bee mortality in German honey bee colonies severely infested with V. jacobsoni. Dead brood from unsealed and sealed infested cells from German colonies with high mite populations also contained much APV. The evidence suggests that V. jacobsoni activates APV replication in adult bees by its feeding behaviour and transmits virus from adult honey bees to pupae. In addition, adult bees, in which APV is multiplying, transmit the virus to unsealed brood in the larval food. 相似文献

Transpuparial transmission of Kashmir bee virus and sacbrood virus in the honey bee (Apis mellifera)
When particles of Kashmir bee virus (KBV) and sacbrood virus (SBV) were fed to larvae of the honey bee, Apis mellifera, in Australian colonies, the resulting pupae became in apparently infected. There was no statistically significant difference in the susceptibility of 1, 2, 3 or 4-day-old larvae for either virus, but 5-day-old larvae were significantly less susceptible to SBV than younger larvae. There was no significant difference in the proportions of pupae that became in apparently infected when, as larvae, they were fed various concentrations of each virus, but significantly more larvae were removed from their cells when fed concentrated preparations of each virus than when fed diluted preparations. Susceptible larvae that became in apparently infected with KBV and SBV developed normally into in apparently infected pupae and later, emerged as in apparently infected worker bees. 相似文献

Inapparent infection of honey bee pupae by Kashmir and sacbrood bee viruses in Australia 总被引:1,自引:0,他引:1
D. J. DALL 《The Annals of applied biology》1985,106(3):461-468
Inapparent infection of pupae of Apis mellifera by Kashmir bee virus (KBV) and sacbrood virus (SBV) was detected by two different methods, in three consecutive summers, from two widely separated locations in Australia. The prevalence of inapparent KBV infections varied from year to year, in contrast to the more consistent levels of inapparent SBV infection. The implications of inapparent infection for the epizootiology of the viruses in Australia are discussed. 相似文献

Occurrence and prevalence of seven bee viruses in Apis mellifera and Apis cerana apiaries in China 总被引:1,自引:0,他引:1
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 were common in both species. This is the first report of detection of IAPV and CBPV in A. cerana. 相似文献

The ectoparasitic mite Tropilaelaps mercedesae (Acari, Laelapidae) as a vector of honeybee viruses 总被引:1,自引:0,他引:1
The ectoparasitic mites Varroa destructor and Tropilaelaps mercedesae share life history traits and both infect honeybee colonies, Apis mellifera. Since V. destructor is a biological vector of several honeybee viruses, we here test whether T. mercedesae can also be infected and enable virus replication. In Kunming (China), workers and T. mercedesae mites were sampled from three A. mellifera colonies, where workers were exhibiting clinical symptoms of deformed wing virus (DWV). We analysed a pooled bee sample (15
workers) and 29 mites for the presence of Deformed wing virus (DWV), Black queen cell virus (BQCV), Sacbrood virus (SBV),
Kashmir bee virus (KBV), Acute bee paralysis virus (ABPV), and Chronic bee paralysis virus (CBPV). Virus positive samples
were analysed with a qPCR. Only DWV +RNA was found but with a high titre of up to 108 equivalent virus copies per mite and 106 per bee. Moreover, in all DWV positive mites (N= 12) and in the bee sample virus–RNA was also detected using RT-PCR and tagged
RT-PCR, strongly suggesting virus replication. Our data show for the first time that T. mercedesae may be a biological vector of DWV, which would open a novel route of virus spread in A. mellifera.

Acute bee paralysis virus (ABPV), Kashmir bee virus (KBV) and Israeli acute paralysis virus (IAPV) are part of a complex of closely related viruses from the Family Dicistroviridae. These viruses have a widespread prevalence in honey bee (Apis mellifera) colonies and a predominantly sub-clinical etiology that contrasts sharply with the extremely virulent pathology encountered at elevated titres, either artificially induced or encountered naturally. These viruses are frequently implicated in honey bee colony losses, especially when the colonies are infested with the parasitic mite Varroa destructor. Here we review the historical and recent literature of this virus complex, covering history and origins; the geographic, host and tissue distribution; pathology and transmission; genetics and variation; diagnostics, and discuss these within the context of the molecular and biological similarities and differences between the viruses. We also briefly discuss three recent developments relating specifically to IAPV, concerning its association with Colony Collapse Disorder, treatment of IAPV infection with siRNA and possible honey bee resistance to IAPV. 相似文献

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 samples was SBV, with an incidence of 60.49%, followed by BQCV in 48.14%, DWV in 6.17%, and KBV in 1.23% of samples. CBPV infection was not detected in larvae samples, and acute bee paralysis virus (ABPV) was not present in both larvae and adult bee. Simultaneous infections with up to four viruses were also identified. Of these, infections with SBV and BQCV were most frequent in 25.61% of samples. The distribution of these viruses varied considerably throughout the geographic regions investigated. The three provinces of Gyeongbuk, Jeonnam, and Chungbuk had the highest frequency of bee viruses. 相似文献

Molecular and phylogenetic characterization of honey bee viruses,Nosema microsporidia,protozoan parasites,and parasitic mites in China 总被引:1,自引:0,他引:1
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 black queen cell virus (BQCV), chronic bee paralysis virus (CBPV), deformed wing virus (DWV), Israeli acute paralysis virus (IAPV), and sacbrood virus (SBV), but not that of acute bee paralysis virus (ABPV) or Kashmir bee virus (KBV). DWV was the most prevalent in the tested samples. Phylogenies of Chinese viral isolates demonstrated that genetically heterogeneous populations of BQCV, CBPV, DWV, and A. cerana‐infecting SBV, and relatively homogenous populations of IAPV and A. meliifera‐infecting new strain of SBV with single origins, are spread in Chinese apiaries. Similar to previous observations in many countries, Nosema ceranae, but not Nosema apis, was prevalent in the tested samples. Crithidia mellificae, but not Apicystis bombi was found in five samples, including one A. c. cerana colony, demonstrating that C. mellificae is capable of infecting multiple honey bee species. Based on kinetoplast‐encoded cytochrome b sequences, the C. mellificae isolate from A. c. cerana represents a novel haplotype with 19 nucleotide differences from the Chinese and Japanese isolates from A. m. ligustica. This suggests that A. c. cerana is the native host for this specific haplotype. The tracheal mite, Acarapis woodi, was detected in one A. m. ligustica colony. Our results demonstrate that honey bee RNA viruses, N. ceranae, C. mellificae, and tracheal mites are present in Chinese apiaries, and some might be originated from native Asian honey bees. 相似文献

Six honey bee viruses were surveyed using RT-PCR in Northern Thailand where about 80% of Thai apiaries are located. Tested samples were found to be positive for deformed wing virus (DWV), acute bee paralysis virus (ABPV), sacbrood virus (SBV) and Kashmir bee virus (KBV). In the collected samples, neither chronic bee paralysis virus nor black queen cell virus nucleic acids could be detected. It was found that DWV was the most widespread and ABPV was the second most prevalent. Kashmir bee virus was found only in the Lampang province where high infestation of Varroa destructor mite occurred. Tropilaelaps, European foulbrood, and Chalkbrood diseases were found in some apiaries. 相似文献

In recent decades, we have realized that honey bee viruses are not, in fact, exclusive to honey bees. The potential impact of Apis-affiliated viruses on native pollinators is prompting concern. Our research addresses the issue of virus crossover between honey bees and native bees foraging in the same localities. We measured the presence of black queen cell virus (BQCV), deformed wing virus (DWV) and sacbrood virus (SBV) in managed Apis mellifera (honey bees) and native Andrena spp. (subgenus Melandrena) bee populations in five commercial orchards. We identified viral presence across sites and bees and related these data to measures of bee community diversity. All viruses were found in both managed and native bees, and BQCV was the most common virus in each. To establish evidence for viral crossover between taxa, we undertook an additional examination of BQCV where 74 samples were sequenced and placed in a global phylogenic framework of hundreds of BQCV strains. We demonstrate pathogen sharing across managed honey bees and distantly related wild bees. This phylogenetic analysis contributes to growing evidence for host switching and places local incidence patterns in a worldwide context, revealing multispecies viral transmission. 相似文献

The sensitivity and specificity of conventional Ouchterlony gel-diffusion, immuno-osmoelectrophoresis (IO), immune serum electron microscopy (ISEM), “decoration,” radioimmunoassay (RIA), and enzyme-linked immunosorbent assay (ELISA) tests for detecting black queen cell virus (BQCV), chronic bee paralysis virus (CBPV), Kashmir bee virus (KBV), and sacbrood virus (SBV) particles in extracts of diseased honeybees were compared. A “slow” ISEM method detected virus particles in extracts of individuals or groups of individuals diluted to 10?3 and 10?4, respectively, whereas the IO method and a “fast” ISEM method using protein A were one-tenth as sensitive, and Ouchterlony gel-diffusion tests were only one-thousandth as sensitive. Using the antibody “decoration” technique, mixtures of serologically unrelated virus particles could be resolved. RIA and ELISA were found to be one thousand times more sensitive than ISEM in detecting the particles of BQCV, CBPV, KBV, and SBV; however, nonspecific reactions occurred when using RIA with very dilute particle suspensions, and this made dilution endpoints difficult to assess, but this did not occur when using the ELISA method. There was little difference in the effectiveness of rabbit or hen antisera in the tests, except when protein A was used as it does not combine with hen antibodies. 相似文献

A comparison was made of the prevalence and relative quantification of deformed wing virus (DWV), Israeli acute paralysis virus (IAPV), black queen cell virus (BQCV), Kashmir bee virus (KBV), acute bee paralysis virus (ABPV) and sac brood virus (SBV) in brood and adult honey bees (Apis mellifera) from colonies selected for high (HMP) and low (LMP) Varroa destructor mite population growth. Two viruses, ABPV and SBV, were never detected. For adults without mite infestation, DWV, IAPV, BQCV and KBV were detected in the HMP colony; however, only BQCV was detected in the LMP colony but at similar levels as in the HMP colony. With mite infestation, the four viruses were detected in adults of the HMP colony but all at higher amounts than in the LMP colony. For brood without mite infestation, DWV and IAPV were detected in the HMP colony, but no viruses were detected in the LMP colony. With mite infestation of brood, the four viruses were detected in the HMP colony, but only DWV and IAPV were detected and at lower amounts in the LMP colony. An epidemiological explanation for these results is that pre-experiment differences in virus presence and levels existed between the HMP and LMP colonies. It is also possible that low V. destructor population growth in the LMP colony resulted in the bees being less exposed to the mite and thus less likely to have virus infections. LMP and HMP bees may have also differed in susceptibility to virus infection. 相似文献

Interactions between pathogens might contribute to honey bee colony losses. Here we investigated if there is an association between the microsporidian Nosema ceranae and the deformed wing virus (DWV) in different body sections of individual honey bee workers (Apis mellifera ligustica) under exclusion of the vector Varroa destructor. Our data provide correlational evidence for antagonistic interactions between the two pathogens in the midgut of the bees. 相似文献

Invasion of alien species has been shown to cause detrimental effects on habitats of native species. Insect pollinators represent
such examples; the introduction of commercial bumble bee species for crop pollination has resulted in competition for an ecological
niche with native species, genetic disturbance caused by mating with native species, and pathogen spillover to native species.
The European honey bee, Apis mellifera, was first introduced into Japan for apiculture in 1877, and queen bees have been imported from several countries for many
years. However, its effects on Japanese native honey bee, Apis cerana japonica, have never been addressed. We thus conducted the survey of honey bee viruses and Acarapis mites using both A. mellifera and A. c. japonica colonies to examine their infestation in native and non-native honey bee species in Japan. Honey bee viruses, Deformed wing
virus (DWV), Black queen cell virus (BQCV), Israeli acute paralysis virus (IAPV), and Sacbrood virus (SBV), were found in
both A. mellifera and A. c. japonica colonies; however, the infection frequency of viruses in A. c. japonica was lower than that in A. mellifera colonies. Based on the phylogenies of DWV, BQCV, and SBV isolates from A. mellifera and A. c. japonica, DWV and BQCV may infect both honey bee species; meanwhile, SBV has a clear species barrier. For the first time in Japan,
tracheal mite (Acarapis woodi) was specifically found in the dead honey bees from collapsing A. c. japonica colonies. This paper thus provides further evidence that tracheal-mite-infested honey bee colonies can die during cool winters
with no other disease present. These results demonstrate the infestation of native honey bees by parasite and pathogens of
non-native honey bees that are traded globally. 相似文献

A survey of six bee viruses on a large geographic scale was undertaken by using seemingly healthy bee colonies and the PCR technique. Samples of adult bees and pupae were collected from 36 apiaries in the spring, summer, and autumn during 2002. Varroa destructor samples were collected at the end of summer following acaricide treatment. In adult bees, during the year deformed wing virus (DWV) was found at least once in 97% of the apiaries, sacbrood virus (SBV) was found in 86% of the apiaries, chronic bee paralysis virus (CBPV) was found in 28% of the apiaries, acute bee paralysis virus (ABPV) was found in 58% of the apiaries, black queen cell virus (BQCV) was found in 86% of the apiaries, and Kashmir bee virus (KBV) was found in 17% of the apiaries. For pupae, the following frequencies were obtained: DWV, 94% of the apiaries; SBV, 80% of the apiaries; CBPV, none of the apiaries; ABPV, 23% of the apiaries; BQCV, 23% of the apiaries; and KBV, 6% of the apiaries. In Varroa samples, the following four viruses were identified: DWV (100% of the apiaries), SBV (45% of the apiaries), ABPV (36% of the apiaries), and KBV (5% of the apiaries). The latter findings support the putative role of mites in transmitting these viruses. Taken together, these data indicate that bee virus infections occur persistently in bee populations despite the lack of clinical signs, suggesting that colony disease outbreaks might result from environmental factors that lead to activation of viral replication in bees. 相似文献

Six bee viruses, which occur in Apis mellifera, were monitored in the Czech Republic between 2006 and 2009. Samples of larvae and pupae collected from hives where American
foulbrood was detected were screened for bee viruses and in the 125 samples of larvae, there was no confirmed case of a larva
infected with both American foulbrood and a bee virus. Of 145 samples infected with the protozoan Nosema apis, there were 23 cases of coinfections with the BQCV virus, 18 with the DWV virus and 11 with the ABPV virus. All coinfections
with three or four viruses were also statistically significant apart from the one between ABPV with CBPV and DWV. The PCA
ordination diagram indicates that BQCV occurs mainly with Nosema apis and DWV mainly with ABPV. 相似文献
