Abstract In highly social bees, queen mandibular pheromone (QMP) is vital for colony life. Both Apis cerana (Ac) and Apis mellifera (Am) share an evolutionarily conserved set of QMP compounds: (E)-9-oxodec-2-enoic acid (9-ODA), (E)-9-hydroxydec-2-enoic acid (9-HDA), (E)-10-hydroxy-dec-2-enoic acid (10-HDA), 10-hydroxy-decanoic acid (10-HDAA), and methyl p–hydroxybenzoate (HOB) found at similar levels. However, evidence suggests there may be species-specific sensitivity differences to QMP compounds because Ac workers have higher levels of ovarian activation than Am workers. Using electroantennograms, we found species-specific sensitivity differences for a blend of the major QMP compounds and three individual compounds (9-HDA, 10-HDAA, and 10-HDA). As predicted, Am was more sensitive than Ac in all cases (1.3- to 2.7- fold higher responses). There were also species differences in worker retinue attraction to three compounds (9-HDA, HOB, and 10-HDA). In all significantly different cases, Am workers were 4.5- to 6.2-fold more strongly attracted than Ac workers were. Thus, Ac workers responded less strongly to QMP than Am workers, and 9-HDA and 10-HDA consistently elicited stronger antennal and retinue formation responses.

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.

AbstractWe investigated the effects of synthetic honey bee (Apis mellifera L.) queen mandibular gland pheromone on colony foraging and brood rearing. Colonies newly established in the spring showed a significant, dose-dependent increase in the number of foragers gathering pollen, and individual pollen foragers returned to the nest with larger pollen loads. These two effects combined resulted in a doubling of the amount of pollen brought into colonies by foraging bees. Brood rearing also increased, but not significantly. In contrast, large, established colonies showed no effects at their summer population peak. We conclude that queen mandibular pheromone can significantly affect foraging, but its effects depend on colony conditions and environmental factors.
