An experiment was conducted to determine the foraging behavior of Apis mellifera L. and Apis cerana F. in rapeseed under cage condition in Chitwan, Nepal during 2012-2013. This experiment showed that Apis cerana F. foraged extra 42 minute per day as compared to Apis mellifera L. Apis cerana F. were more attracted to nectar, whereas Apis mellifera L. were more attracted to pollen collection throughout the day. The activities, in into hives and out from hives, for both species were recorded more at 2:00 pm and least at 8:00 am. The highest in-out were observed at 2:00 pm on both species as Apis mellifera L. 44.33 bees entered into hives and 49.66 bees went out of hives, whereas lower number of Apis cerana F. 43.66 bees entered into hives and 48.16 bees were out of hives. Apis mellifera L. collect 1.22:1 and 0.41:1 pollen nectar ratio at 10:00 am and 4:00 am whereas at same hours Apis cerana collect 1.16:1 and 0.30:1 pollen nectar ratio. Apis cerana F. foraged significantly higher number of rapeseed flowers and plants as compared to Apis mellifera L. under caged condition. It shows that Apis cerana F. was more efficient pollinator as compared to Apis mellifera L. under caged condition.

Natural Infestation

Varroa jacobsoni foi descrita em 1904 por Oldenans em Java em cria de Apis cerana. O nível de infestação com V. jacobsoni mede indiretamente o grau de tolerância da A. mellifera à V. jacobsoni. O estudo foi conduzido no Município de Mandirituba-PR. Os enxames foram capturados com caixa iscas. A percentagem de infestação V. jacobsoni foi resistrada mensalmente. Aplicando-se o teste de Friedman e usando-se o rank de cada colônia, separou-se os grupos de colônias homogêneas. A tendência sazonal foi demostrada com representação gráfica. O experimento foi delineado segundo blocos inteiramente casualizados. Em todas as amostras foi encontrado o ácaro V. jacobsoni. Diferenças significativas entre as colônias foram observadas. Na população de Apis mellifera scutellata existem três grupos homogêneos de colônias quanto ao nível de infestação com esse ácaro. O inverno é a época onde o grau de infestação com V. jacobsoni é mais elevado. Natural infestation of Apis mellifera scutellata (Hymenoptera; Apidae) by Varroa jacobsoni (Mesostigmata; Varroidae) Abstract Infestation by Varroa jacobsoni in an offspring of Apis cerana was first described as early as 1904 in Java. Since the level of infestation by V. jacobsoni may be an indirect procedure to measure the Apis mellifera scutellata tolerance degree towards it, the present research was carried out in order to evaluate such biological relationship between host and parasite and its implication in the Apis mellifera scutellata productivity. This study was carried out at Mandirituba, Paraná, Brazil. The swarms were captured with bait boxes. The percentage of V. jacobsoni infestation was established monthly. According to the Friedman test ant through the rank, homogeneous colonies were single out. The experiment has been delineated as entirely randomized blocks.

AbstractNosema apis is a pathogen spesific for the European honeybee, Apis mellifera L., while Nosema ceranae is specific for the Asian honeybee, Apis cerana. Turkey provides different environmental and host conditions for both Nosema species. The aim of the study is to determine the dynamic of N. cerenae and N. apis seasonal infection. A number of samples were collected from different apiaries between 2009-2016 years. The samples were kept at −20°C in the laboratory. Light microscopy was used for spore counting and molecular techniques were used to identify the Nosema species. The results showed that winter season had an impact on the type of Nosema as well as on infection rates. The number of N. ceranae spores decreases significantly at low temperatures (≤ 5°C). The winter period was found to be the main factor affecting nosema infection level and dominancy of Nosema ceranae. Furthermore, co-infection of both species is an indicator of the dynamics of N. apis and N. ceranae. This study suggests, that there is a dynamic prevalence among the Nosema species depending of the average winter temperature and not a replacement of N. apis by N. ceranae.

Long Term Survey

AbstractSince 2016, Apis cerana sacbrood virus (AcSBV) has been recorded in Taiwan. It is epizootic in Apis cerana (Hymenoptera: Apidae) and causing serious loss of A. cerana. Herein, we performed a long-term survey of AcSBV prevalence in the populations of A. cerana in Northern Taiwan from January 2017 to July 2018. The surveillance of AcSBV prevalence in A. mellifera (Hymenoptera: Apidae) populations was starting and further confirmed by sequencing since April 2017; thus, these data were also included in this survey. In our survey, the average prevalence rates of AcSBV were 72 and 53% in A. cerana and A. mellifera, respectively, in 2017, which decreased to 45 and 27% in 2018. For the spatial analysis of AcSBV in two honey bee populations, Hsinchu showed the highest prevalence, followed by New Taipei, Yilan, Taipei, and Keelung, suggesting that AcSBV might have come from the southern part of Taiwan. Interestingly, the AcSBV prevalence rates from A. cerana and A. mellifera cocultured apiaries gradually synchronized. The result of phylogenetic analysis and comparison of the annual AcSBV prevalence in A. cerana-only, A. mellifera-only, and A. cerana/A. mellifera cocultured sample sites indicate cross-infection between A. cerana and A. mellifera; however, AcSBV may lose the advantage of virulence in A. mellifera. The evidence suggested that the transmission of AcSBV might occur among these two honey bee species in the field. Therefore, A. mellifera may serve as a guard species to monitor AcSBV in A. cerana, but the cross-infection still needs to be surveyed.

Foraging Preference

A study was conducted to evaluate foraging behavior of Apis cerana F. and A. mellifera L. in broccoli blooms under caged and open conditions in Chitwan, Nepal during 1999-2000. The study showed that both the bee species preferred open plot for foraging and A. cerana F. foraged significantly (P < 0.05) higher number of broccoli flowers (an average of 11.39 and 12.11 flowers per minute) as compared to A. mellifera L. (an average of 9.03 and 10.89 flowers per minute) under caged and open conditions, respectively. The number of bees foraging per plant was not significantly different, showing broccoli bloom equally preferable to both honeybee species.
