“…Although a total of 113 pollen types were registered in the analyzed samples, which reinforces the generalist behavior of A. mellifera (Köppler et al 2007), some samples were classified as monofloral (PI1, BA7, and BA10). This corroborates the results obtained by Suwannapong et al (2012), who reported honey bees preference for plants that provide resources in greater quantity, taking advantage of the pollen source until its exhaustion.…”

The Northeastern Brazil has xerical vegetation with different biomes. Its botanical heterogeneity represents shelter for diverse fauna. The region is rich in bees, which demand the resources offered by the plants, and provide pollination services. Bee pollen has been used as a beneficial food source for humans due to its high nutritional content and being a natural antioxidant. Pollen analysis can determine the plant species visited by bees, using them as the source of pollen supply. This study aimed to identify the main pollen types present in the pollen collected by Apis mellifera in the Northeastern Brazil and to define its botanical affinity. Commercial bee pollen samples produced in the region were treated by acetolysis method, mounted on slides, and the frequency of occurrence was estimated for each type of pollen. It was possible to distinguish 113 pollen types belonging to 35 botanical families, distributed in 92 genera. Fabaceae and Asteraceae were the families that most contributed to pollen types. Pollen types of Cocos nucifera and Myrcia were found in more than 50% of the samples. The families Arecaceae and Fabaceae showed high beekeeping potential. There is a striking similarity between the pollen samples from the states of Pernambuco and Rio Grande Norte.

“…We assume that there may have been a gradual transformation of sensory placodea deep to sensory placodea shallow in the pesticide exposed populations. The observed affected sensillae in our study have been reported earlier to play an important role in olfaction 45 46 47 . Hence, their deformation, damage, size and number reduction in the antennae of pesticide exposed wild honey bees can be assumed to interfere with olfaction.…”

Little information is available regarding the adverse effects of pesticides on natural honey bee populations. This study highlights the detrimental effects of pesticides on honey bee olfaction through behavioural studies, scanning electron microscopic imaging of antennal sensillae and confocal microscopic studies of honey bee brains for calcium ions on Apis cerana, a native Indian honey bee species. There was a significant decrease in proboscis extension response and biologically active free calcium ions and adverse changes in antennal sensillae in pesticide exposed field honey bee populations compared to morphometrically similar honey bees sampled from low/no pesticide sites. Controlled laboratory experiments corroborated these findings. This study reports for the first time the changes in antennal sensillae, expression of Calpain 1(an important calcium binding protein) and resting state free calcium in brains of honey bees exposed to pesticide stress.Pesticide exposure can have direct effects on individual bees as well as indirect effects on entire colonies 1 and has been cited as one of the potential causes for global honey bee loss through colony collapse disorder 2,3

“…Bees and plants are mutually interdependent on each other. Honey bees collect both nectar and pollen during their foraging activity and act as a potent pollinator for plants due to their morphological structure that facilitates pollen attachment, transfer and deposition (Suwannapong et al, 2012). Nectar is the primary source of carbohydrates while pollen acts as a rich source of protein which guarantees the survival and longevity of honeybees (Schmidt et al, 1987;Roulston & Buchmann, 2000).…”

The present investigation aims to determine the botanical origin and chemical composition of bee pollen samples (n =22) harvested from Apis cerana hives domesticated in Pauri Garhwal (Uttarakhand, India). The majority (95%) of the samples were unifloral in their botanical origin. All the identified pollens belonged to eighteen plant families, among which Rutaceae, Asteraceae and Brassicaceae were found dominant. The chemical parameters soluble sugars, starch, crude protein, amino acids and phenolic contents were analyzed calorimetrically and were found in the range from 0.2 to 26.09 mg/g, 0.22 to 11.04 mg/g, 13.40 to 191.41 mg/g, 2.01 to 6.48 mg/g, and 5.10 to 35.50 mg GAE/g, respectively. Statistically significant differences (p<0.05) were observed between the chemical contents of the analyzed samples and a moderate correlation (r= 0.40; n=22) was observed between total soluble sugars and crude protein. Bee pollens as a good source of nutrition, medicine and dietary supplement for both humans and bees, demonstrate the important need to define bee pollen from different regions of India in order to develop bee pollen quality standards.
