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.

The abundance and diversity of rapeseed insect flower visitors were assessed by using insect pan traps, sweep net and visual observations at different blooming stage of rapeseed at Jutpani VDC, Chitwan district, Nepal during 2012-013. The pollinator fauna of rapeseed included twenty one species from six different insect orders. Hymenopteran (77.95%) species were the most abundant insects visiting rapeseed followed by Diptera (12.23%) and Lepidoptera (3.49%). Honeybees were the dominant group of pollinators and among honeybees, Apis mellifera L. was the most dominant one (36.34%) followed by Apis florea F. (12.45%), Apis cerana F. (11.14%) and Apis dorsata F. (5.68%). The higher abundance and diversity of pollinators were observed at 12:00 to 1:00 pm and the diversity was related to the crop blooming stage. Therefore, pollinator's friendly cultivation practices should be followed for conservation and management of insect pollinators for higher production and productivity of rapeseed crop under Chitwan condition. Journal of the Institute of Agriculture and Animal Science.

Plant-pollinator interactions are often considered as tightly coevolved, mutualistic relationships. The present study aimed at determining the flower visiting bees of the vegetable crop,Solanum violaceum, and the efficiency of buzz pollination by bees on fruit and seed production in Sri Lanka. Seven bee species:Hoplonomia westwoodi,Amegilla comberi,Patellapis kaluterae,Xylocopa tenuiscapa,Apis dorsata,Trigona iridipennis, andCeratina hieroglyphicavisited the flowers ofS. violaceum, and the first four species were buzzing bees. Buzzing bees were the first to visitSolanumflowers and were followed by nonbuzzing bees. Handling time ofH. westwoodiandP. kaluteraevaried with the availability of pollen in anthers that deplete with the age of flower and stayed longer at new flowers than at old flowers. Handling time of the larger buzzing bee,H. westwoodi, was higher than that of the smallerP. kaluterae. The fruit set, seed set, and seed germinability in flowers visited by buzzing bees were significantly higher than those of the flowers bagged to exclude pollinators.

Before And After

The intestinal microbial community composition of different bee species typically has host specificity, yet little is known about the underlying formation mechanism. There are signs that dietary habits vary in different bee species, suggesting that there may be close relationships between dietary habits and intestinal microorganisms. We explored this hypothesis by comparing the dietary habits and gut microbiota of two common bee species (Apis mellifera L. and Apis cerana cerana) in China. Bee bread and midgut samples from wild and laboratory-reared bees were collected, and the differences in intestinal microbial community composition and growth and development before and after the change in dietary habits of different bee species were compared. We found that the two sympatric species had different dietary specializations and similar metagenomic diversities. The microbiota composition differed between the two species. Moreover, we revealed that changes in native dietary habits destroyed the intestinal microbiota community composition, negatively affecting the growth and development of honeybees.
