“…No colony losses in this study were directly attributed to Varroa mite presence or their associated pathogens. These results are in contrast to other studies around the world where Varroa mites played a significant or central role in colony losses (Bailey and Ball, 1991;Brodschneider et al, 2010;Dainat et al, 2012b;Dietemann et al, 2012;Guzman-Novoa et al, 2010;Ritter, 1981;Rosenkranz et al, 2010;Schäfer et al, 2010;Shimanuki et al, 1994). Also, the close association between Varroa mites and viruses (especially DWV, ABPV) and the subsequent colony losses they usually cause (Berthoud et al, 2010;Dainat et al, 2012a;Martin et al, 2012) were not observed in this study.…”

“…This study confirms the importance of the food quality (Brodschneider and Crailsheim 2010), considered as nutritional value and pesticide contamination, for the physiological development of honeybees, which could be evaluated through the assessment of the morphology of HPGs in young bees.…”

“…The abundance and quality of pollen has been individuated as a relevant factor in influencing honeybee health not only at the individual level but also at the colony level (Brodschneider and Crailsheim 2010;Naug 2009). Pollen provides the only source of proteins which are needed to ensure a correct development and functioning of many organs and tissues in honeybees (Haydak 1970).…”

Combined effect of pollen quality and thiamethoxam on hypopharyngeal gland development and protein content in Apis mellifera

-Pollen diet is essential to nurse bees to develop hypopharyngeal glands (HPGs) and produce royal jelly to feed larvae. The effect of different diet regimes combined with pesticide exposure on the development of HPGs in honeybees was studied. In particular, a high-quality pollen mixture (high pollen diversity and protein content) and a low-quality diet (low pollen diversity and protein content) were combined with the chronic administration of thiamethoxam (10 and 40 μg/L). The impact of these stressors was evaluated by measuring the size of HPG acini and the total protein content of bee heads in 8-and 12-day-old bees. Bees fed with sub-lethal concentrations of thiamethoxam and with the low-quality diet exhibited smaller and irregularly shaped acini. The total protein content in bee head was also affected by pesticide administration, while the pollen quality did not cause significant modifications. In conclusion, these results highlighted the importance of the food quality, considered as nutritional value and pesticide contamination, for the physiological development of honeybees.HPGs / honeybee / neonicotinoid / pollen diet / chronic toxicity

“…The average yield of Group III was greater than that of Group VI (17.47kg and 12.62kg, respectively), and the agricultural area of Group VI was superior to that of the group III. According to Brodschneider and Crailsheim (2010), in order for a colony to have good productivity it is necessary to balance their nutrition, such as the supply of carbohydrates, proteins, lipids, vitamins and minerals. However, due to monoculture, diversity has been reduced, affecting the nutrition of bees and consequently decreasing their production .…”

This study aimed to develop a Geographic Information System (GIS), for storage of information and geographic location of apiaries in eight counties in western Paraná; study the local flora; the land used; and the honey productivity in the harvest of 2010 in two of these areas: Marechal Cândido Rondon and Santa Helena. In order to do so we used the software SPRING, delimiting a radius of action of bees of three kilometers around the apiaries. We interviewed and registered 126 beekeepers with 383 apiaries. By using the images we selected areas with greater and lower overlap of hives in Marechal Cândido Rondon (144 and 44 hives, respectively) and Santa Helena (165 and 40 hives, respectively), in a three kilometers radius, selecting 15 colonies in each area, for the study of the parameters cited. In the multivariate analysis of the grouping, five groups were formed, by their similarity of management, indicating the higher average production in the hives of the most populated area of Santa Helena and lower average production in the most populated of Marechal Cândido Rondon. The grouping of hives, the differences in the production of honey and floristic survey indicated that these differences could be associated with management, floristic and climatic differences recorded in the period of production, in the areas studied.
