A total of 11 bee species belonging to two families Apidae and Megachilidae was identified. The identified species were Apis dorsata, Apis mellifera, Apis cerana, Apis florea, Ceratina binghami, Ceratina nigrolateralis, Xylocopa aestuans, Xylocopa violacea, Xylocopa latipes, Megachile disjuncta and Megachile umbripennis. The species were identified by using standard taxonomic keys. Details of external morphology like head, wing venation, antennal type, physical coloration etc. were used in the keys. The bees were collected from three areas of Dhaka city - Curzon Hall, Ramna Park and Sher-e-Bangla Agricultural University from October 2017 to May 2018. During the study period it was observed that the richness of bee species was found maximum during the month of October (31.01%) and was more abundant in Curzon Hall and Sher-e-Bangla Agricultural University area than the Ramna park area. The bee A. dorsata was the most abundant (about 36.23% of the total population) and M. umbripennis was the least abundant (about 1.74% of the total population) species in the study areas. It was also observed that bee species were more attracted to the yellow flowers specially Cosmos sulphureus and Tecoma stans than the other coloured flowers. J. Biodivers. Conserv. Bioresour.

The present studies on diversity and foraging behaviour of insect pollinators on Murraya koenigii (L. )was carried out during March - April 2019 at Akot town situated in Akola district of Maharashtra. Ten insect species visited Murraya koenigii flowers viz. Five hymenopterans and five lepidopterons. This study revealed that hymenopterans were found to be the most dominant (97. 5%) flower visitors, followed by lepidopteron insects (2. 5%). Among these Apis florea, Apis cerana indica, and Apis dorsata were found to be the most frequent pollinators. The result on foraging behaviour of bees Apis florea started visiting Murrya koenigii flowers in early morning at 06. 00 hrs, Apis cerana indica at 6. 30 hrs and ceased their activity later in the evening. Apis mellifera and Apis dorsata , they started visiting the flowers from 7. 00hrs. Maximum foraging was by Apis florea (12 flowers /minute)followed by Apis cerana indica (10 flowers/minute )and Apis dorsata (9-10 flowers /minute). Time spent per flower was the maximum with lepidopteron (25 sec. /flower) followed by Moth (15 sec. /flower)

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.
