“…However, the pollen protein content of Asteraceae is at the low end of the spectrum for beepollinated plants , and beekeepers consider these pollens to be a poor resource (Schmidt et al, 1987). Very poor development of two species of Osmia, generalist solitary bees, was recorded on the pollen of dandelion Tanacetum vulgare (Asteraceae) (Sedivy et al, 2011), and the inability of honeybees to rear brood on dandelion pollen has been attributed to deficiencies in several amino acids (Loper and Cohen, 1987).…”

-The nutritional needs of bees are receiving renewed attention in the context of declining bee populations and changes in land use that threaten floral resources. We present a comprehensive analysis of the nutritional composition of sunflower (Helianthus annuus) pollen, comparing hand-collected, bee-collected and stored pollen. As found in previous studies, the protein content of sunflower pollen was relatively low compared to other important bee forage plants. In the cultivars tested two essential amino acids, methionine and tryptophan, are likely to be below the minimum requirements for honeybees. Fatty acid composition showed lauric acid to be most abundant, followed by palmitic and α-linolenic acids. While sunflower offers abundant and accessible pollen, its quality may hinder bee development when it is an exclusive pollen source, and the cultivars of such mass-flowering crops may vary in value for pollinators.

“…A decrease in availability and protein content of bee-collected pollen may result in the development of smaller HPGs (DeGrandi-Hoffman et al 2010; Di Pasquale et al 2013), less brood reared Electronic supplementary material The online version of this article (doi:10.1007/s13592-016-0435-9) contains supplementary material, which is available to authorized users. (DeGrandi-Hoffman et al 2008;Herbert et al 1977), shorter longevity (Di Pasquale et al 2013;Schmidt et al 1987) and recruitment of hive bees at a younger age (Sagili and Pankiw 2007), which ultimately entails a reduced lifespan (Khoury et al 2011). Pollen also represents one of the most frequent ways of exposure to pesticides (Krupke et al 2012;Mullin et al 2010), particularly relevant for nurse bees and larvae, which consume the highest amount of stored pollen (Rortais et al 2005).…”

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

et al. 2016

-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

“…This result may relate to a "species diversity preference" in which nutrients from various floral sources are required by honey bee colonies, such that bees fly over and pass up profitable food sources to exploit other plant species (Gary 1992). Schmidt (1984) showed that a preference for pollen mixtures over certain unifloral sources may explain the polylectic nature of the honey bee colony, and Schmidt et al (1987) demonstrated that a five-pollen blend increased honey bee longevity more than single pollen sources. Also, whereas the nutritional value of caraway pollen is apparently unknown, the protein content of Brassica and Melilotus pollens, regularly encountered in traps during the latter part of caraway flowering phenology, is high (Pernal and Currie 2000).…”

Langenberger, M. W. and Davis, A. R. 2002. Honey bee pollen foraging in relation to flowering phenology of biennial caraway (Carum carvi L.). Can. J. Plant Sci. 82: 203-215. Biennial caraway (Carum carvi L.) is a specialty spice crop in Saskatchewan, yet little was known about fundamental agronomic traits, such as its flowering phenology, plant density, attraction to potential pollinators, and prospective honey yield. At five commercial fields in 1998 and 1999, biennial caraway flowered for 7 wk, beginning in late May or early June and finishing by early to mid-July. Under optimal conditions, and assuming intense foraging activity by honey bees (Apis mellifera L.), caraway might yield 70-134 kg honey ha -1 . However, weights of colonies near fields of caraway (0.47-4.2 hives ha -1 ) changed little while honey bees were predominant foragers on that crop. Then, in the second half of the caraway flowering period, when honey bees had almost deserted those fields as indicated by observation and pollen-trap analyses, hive weights rose steadily due to a switch to nearby crops of canola (Brassica spp.) and sweet clover (Melilotus spp.), which had begun to flower. Whereas biennial caraway is rated as negligible to only moderate for its honey potential in Saskatchewan, 83% of honey bees visiting caraway florets gathered pollen. Moreover, caraway pollen entering hives averaged 11% of total pollen (dry weight) over the entire flowering period of the crop, but 36.5% during the first half of flowering phenology, suggesting that biennial caraway may constitute a valuable source of protein for honey bees, particularly during colony build-up in spring. ) est une plante condimentaire de spécialité cultivée en Saskatchewan dont on connaît mal les grands paramètres agronomiques tels la phénologie de la floraison, la densité du peuplement, l'attrait pour les insectes pollinisateurs et la production éventuelle de miel. En 1998 et 1999, le carvi bisannuel a fleuri durant sept semaines dans cinq champs commerciaux, soit de la fin de mai ou du début de juin au début ou au milieu de juillet. Dans des conditions optimales et en supposant un butinage intense des abeilles (Apis mellifera L.), le carvi peut donner de 70 à 134 kg de miel par hectare. Pourtant, le poids des colonies à proximité des champs (0,47 à 4,2 ruches par hectare) ne varie guère même si les abeilles sont les principaux insectes s'activant sur cette culture. Vers la deuxième partie de la floraison, quand les abeilles ont presque déserté les champs de carvi, comme l'ont révélé les observations et l'analyse des pièges à pollen, on a constaté une hausse abrupte du poids des ruches, les abeilles étant passées aux cultures voisines de canola (Brassica sp.) et de mélilot (Melilotus sp.) dont la floraison venait de commencer. Bien que le carvi bisannuel soit considéré comme une culture produisant une quantité négligeable à moyenne de miel en Saskatchewan, 83 % des abeilles qui butinent ses fleurs en prélèvent le pollen. Le pollen de carvi introduit dans les ruches représentait 1...
