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.

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.
