AbstractHost shifts of parasites are often causing devastating effects in the new hosts. The Varroa genus is known for a lineage of Varroa destructor that shifted to the Western honey bee, Apis mellifera, with disastrous effects on wild populations and the beekeeping industry. Despite this, the biology of Varroa spp. remains poorly understood in its native distribution range, where it naturally parasitizes the Eastern honey bee, Apis cerana. Here, we combined mitochondrial and nuclear DNA analyses with the assessment of mite reproduction to determine the population structure and host specificity of V. destructor and Varroa jacobsonii in Thailand, where both hosts and several Varroa species and haplotypes are sympatric. Our data confirm previously described mite haplogroups, and show three novel haplotypes. Multiple infestations of single host colonies by both mite species and introgression of alleles between V. destructor and V. jacobsonii suggest that hybridization occurs between the two species. Our results indicate that host specificity and population genetic structure in the genus Varroa is more labile than previously thought. The ability of the host shifted V. destructor haplotype to spillback to A. cerana and to hybridize with V. jacobsonii could threaten honey bee populations of Asia and beyond.

A New Species

The gut of honey bees is characterized by a stable and relatively simple community of bacteria, consisting of seven to ten phylotypes. Two closely related honey bees, Apis mellifera (western honey bee) and Apis cerana (eastern honey bee), show a largely comparable occurrence of those phylotypes, but a distinct set of bacterial species and strains within each bee species. Here, we describe the isolation and characterization of Ac13T, a new species within the rare proteobacterial genus Frischella from A. cerana japonica Fabricius. Description of Ac13T as a new species is supported by low identity of the 16S rRNA gene sequence (97.2 %), of the average nucleotide identity based on orthologous genes (77.5 %) and digital DNA–DNA hybridization relatedness (24.7 %) to the next but far related type strain Frischella perrara PEB0191T, isolated from A. mellifera. Cells of Ac13T are mesophilic and have a mean length of 2–4 µm and a width of 0.5 µm. Optimal growth was achieved in anoxic conditions, whereas growth was not observed in oxic conditions and strongly reduced in microaerophilic environment. Strain Ac13T shares several features with other members of the Orbaceae , such as the major fatty acid profile, the respiratory quinone type and relatively low DNA G+C content, in accordance with its evolutionary relationship. Unlike F. perrara , strain Ac13T is susceptible to a broad range of antibiotics, which could be indicative for an antibiotic-free A. cerana bee keeping. In conclusion, we propose strain Ac13T as a novel species for which we propose the name Frischella japonica sp. nov. with the type strain Ac13T (=NCIMB 15259=JCM 34075).

Decline in honey bee populations has become a matter of concern and their conservation is very essential to sustain essential ecosystem services. They provide making available continuous supply of floral resources is of immense value in conserving honey bees. The effectiveness of an ornamental creeper, Antigonon leptopus Hook. & Arn as a sustainable bee forage plant was evaluated. It attracts four major native species of honey bees viz., Apis cerana, A. florea, A. dorsata and Tetragonula iridipennis. The wild little bee, A. florea was the most dominant forager followed by the Indian bee, A. cerana. The plant is amenable for easy multiplication through seeds as well as cuttings and meets both aesthetic and ecological needs. Using Antigonon, different studies related to honey bees like assessing species diversity, foraging behaviour, temperature driven shifts etc. can be carried out. Popularising perennial bee flora like Antigonon would help in conserving honey bees in both natural and urban habitats. Since Antigonon attracts all species of honey bees throughout the year, it could be utilized as a potential bioindicator of honey bee populations in a given environment.

Insect Visitors

Reproductive biology of saprophytic plants has been poorly studied. Epipogium roseum (D.Don) Lindl. is a small saprophytic orchid that is widely distributed in tropical and subtropical Asia, Australia and Africa. The floral biology and insect visitation of E. roseum were studied in Xishuangbanna, south Yunnan Province, China. E. roseum possesses an obligate self-pollination system, in which the degenerative rostellum has lost its function as a physical barrier separating the stigma and stamens (pollinia), allowing contact between the stigmatic secretions and the pollinia during bud development. Flowers of E. roseum usually open and successfully attract insect visitors. The Asian honey bee (Apis cerana cerana) was the only visitor observed, and regularly visited flowers of E. roseum for nectar. However, these bees did not carry pollinia away after visiting the flowers due to the absence of a viscid disk in E. roseum; the results of experiments also indicated that the Asian honey bee does not contribute to fruit set in E. roseum. The visiting frequency of Asian honey bees to flowers of E. roseum varied both spatially and temporally. E. roseum does not undergo outcrossing mediated by insects and is adapted to obligate self-pollination. We suggest that this may have evolved because of the uncertainty of pollinator services associated with its saprophytic lifestyle. Our current studies do not support the hypothesis that obligate autogamy is favoured by myco-heterotrophic plants due to resource limitations.

Indigenous and exotic honey bee species were evaluated for their hygienic behavior in the climatic condition of Peshawar Khyber Pakhtunkhwa, Pakistan. Colonies of equal strength from indigenous (Apis cerana) and exotic (Apis mellifera) species were selected for the study. The same colonies were tested in two seasons. Sealed brood were killed with different methods i.e pin killed and freeze killed. The uncapping of cells and brood removal was recorded at different intervals. Significant differences were recorded between hygienic behavior of both species of honey bees. Apis cerana showed significantly superior hygienic behavior than Apis mellifera in both seasons. At different intervals in both species significant differences were recorded. A significant difference was recorded after 12 and 24 hours between the species in both seasons. No significant differences were recorded after 48hours in both species. From the study it is concluded that indigenous honey bee species has superior hygienic behavior than exotic species.

Colony Survival

Background Managed, feral and wild populations of European honey bee subspecies, Apis mellifera, are currently facing severe colony losses globally. There is consensus that the ectoparasitic mite Varroa destructor, that switched hosts from the Eastern honey bee Apis cerana to the Western honey bee A. mellifera, is a key factor driving these losses. For >20 years, breeding efforts have not produced European honey bee colonies that can survive infestations without the need for mite control. However, at least three populations of European honey bees have developed this ability by means of natural selection and have been surviving for >10 years without mite treatments. Reduced mite reproductive success has been suggested as a key factor explaining this natural survival. Here, we report a managed A. mellifera population in Norway, that has been naturally surviving consistent V. destructor infestations for >17 years. Methods Surviving colonies and local susceptible controls were evaluated for mite infestation levels, mite reproductive success and two potential mechanisms explaining colony survival: grooming of adult worker bees and Varroa Sensitive Hygiene (VSH): adult workers specifically detecting and removing mite-infested brood. Results Mite infestation levels were significantly lower in surviving colonies and mite reproductive success was reduced by 30% when compared to the controls. No significant differences were found between surviving and control colonies for either grooming or VSH. Discussion Our data confirm that reduced mite reproductive success seems to be a key factor for natural survival of infested A. mellifera colonies. However, neither grooming nor VSH seem to explain colony survival. Instead, other behaviors of the adult bees seem to be sufficient to hinder mite reproductive success, because brood for this experiment was taken from susceptible donor colonies only. To mitigate the global impact of V. destructor, we suggest learning more from nature, i.e., identifying the obviously efficient mechanisms favored by natural selection.

Apis cerana, which is often known as honey bee, has spread from Afghanistan, China, Japan, to Indonesia. This distribution cannot be separated from Apis cerana's ability to survive by needing food. Pollen and nectar are the main food sources for Apis cerana in maintaining life. Apis cerana is widely cultivated by the community with its potential. This article aims to describe in more detail about the forage plants from Apis cerana and how the feeding strategies of honey bees were assembled from several studies in various regions, both in Indonesia and outside Indonesia as well as comparing these daily activities with other Apidae. The discussion is focused on the comparative analysis of the daily activities of Apis cerana with other Apidae to see the uniqueness of Apis cerana which is a factor in the number of bees being cultivated.

Bee Viruses

Emerging infectious diseases are often the products of host shifts, where a pathogen jumps from its original host to a novel species. Viruses in particular cross species barriers frequently. Acute bee paralysis virus (ABPV) and deformed wing virus (DWV) are viruses described in honey bees (Apis mellifera) with broad host ranges. Ants scavenging on dead honey bees may get infected with these viruses via foodborne transmission. However, the role of black garden ants, Lasius niger and Lasius platythorax, as alternative hosts of ABPV and DWV is not known and potential impacts of these viruses have not been addressed yet. In a laboratory feeding experiment, we show that L. niger can carry DWV and ABPV. However, negative-sense strand RNA, a token of virus replication, was only detected for ABPV. Therefore, additional L. niger colonies were tested for clinical symptoms of ABPV infections. Symptoms were detected at colony (fewer emerging workers) and individual level (impaired locomotion and movement speed). In a field survey, all L. platythorax samples carried ABPV, DWV-A and –B, as well as the negative-sense strand RNA of ABPV. These results show that L. niger and L. platythorax are alternative hosts of ABPV, possibly acting as a biological vector of ABPV and as a mechanical one for DWV. This is the first study showing the impact of honey bee viruses on ants. The common virus infections of ants in the field support possible negative consequences for ecosystem functioning due to host shifts.

The Difference

AbstractThe infestation of honey bees by the endoparasitic tracheal mite Acarapis woodi was first discovered in Apis mellifera on the Isle of Wight, England, and the mite has since spread to all continents except Australia. Since 2010, this tracheal mite has spread rapidly in the Japanese honey bee, Apis cerana japonica, of mainland Japan, causing considerable colony mortality. In contrast, infestations by the mites in the imported and managed European honey bee, A. mellifera, have rarely been observed in Japan. A previous laboratory experiment revealed a difference in susceptibility by demonstrating that the tracheal mite more frequently enters tracheae of A. cerana than those of A. mellifera. In this study, we compared autogrooming responses of A. cerana and A. mellifera by depositing a mite on each honey bee’s mesoscutum, and we then assessed the efficacy of autogrooming to remove the mite. The bees that received mites more frequently showed an autogrooming response compared to unchallenged bees in both bee species. However, a significantly greater proportion of A. mellifera individuals autogroomed compared to A. cerana. In addition, when bees autogroomed, A. mellifera removed the tracheal mite more effectively than A. cerana. When considering all bees in the mite-deposited group, the proportion of mite removal in A. mellifera was almost twice as high as that in A. cerana. Thus, the difference in susceptibility to the tracheal mite between these two bee species is attributed to the difference in the behavioral response threshold to mites and the effectiveness of mite removal by grooming.
