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)

This paper presents the finding of the field experiment conducted on monitoring of flower visiting insects on buckwheat (Fagopyrum esculentum Moench.) at farmers’ field during winter, 2012/13 at Meghauli, Chitwan, Nepal. The abundance and distribution of flower visiting insects were studied by monitoring with insect net and pan traps at 500 m, 1500 m and 2800 m from the natural habitat (forest). The wild insects (wasps and Apis dorsata F.) were found higher near to natural habitat and domesticated insects (Apis mellifera L. and Apis cerana F.) found more away from the natural habitat or close to housing and apiaries. Besides, Apis florea F., Andrena sp., Synoeca sp., Chalcid sp., Formica sp., Syrphus sp. and various Dipteran, Coleopteran, and Lepidopteran were also the flower visitors of buckwheat close to natural habitat. So, the diversity index varied with distance from the natural habitat, i.e. increase on proximity to natural habitat, i.e. 1.11, 1.25 and 1.62 at 2800 m, 1500 m and 500 m, respectively on sweeping with insect net and 0.65, 1.04 and 1.30 at 2800 m, 1500 m and 500 m, respectively on setting pan traps. Thus, the number and diversity of flower visiting insects get increased on proximity to natural habitat suggesting either conservation of natural habitat (forest) near farming communities or shifting of buckwheat cultivation near to natural habitat for adequate pollination and production.Int J Appl Sci Biotechnol, Vol 4(3): 380-385

Nest site selection is critical for social insects since poor choices can heighten predation risks and result in reproductive failure (Frankset al. 2002). Social bees vary in their nest site requirements and among theApisbees in South Asia,Apis dorsataandA. floreanest in open combs, whereasApis cerananests in cavities (Crane 1999).Apis dorsataoften nests in aggregations, and the large open nests can be about 1.5 m wide and are located in sites such as cliff faces or on the underside of branches of tall trees that are inaccessible to most predators except skilled fliers and climbers (Crane 1999, Seeleyet al. 1982).Apis dorsata, which is widely distributed in tropical and subtropical Asia, is an important source of honey and wax for local communities, and understanding its nesting biology would help in the management and conservation of this economically important species.
