“…However, the Na levels in the 2d-RJ were higher, although they were significantly lower in the O2d-RJ. Because the 2d-RJ consists of 1d-RJ and O2d-RJ, the additional Na content worker bees feed female larvae the same food during their first 3 days of larval development (Haydak 1943(Haydak , 1970Nijhout and Wheeler 1982;Wilde and Beetsma 1982). Zheng et al (2011) found that the composition of RJ harvested at different times varied significantly.…”

“…The worker larvae are subsequently fed a mixture of royal jelly, pollen and honey, while the older queen larvae are provided with abundant royal jelly (Haydak 1943). The quality and quantity of larval food is believed to be the primary catalyst for the differentiation in development (Haydak 1943;Winston 1991). There are few reports on the differences between royal jelly (RJ) and worker jelly (WJ).…”

-In this study, the chemical and mineral composition and trace elements in royal jelly (RJ) and worker jelly (WJ) and in royal jelly on particular days (only-2-day RJ [O2d], only-3-day RJ [O3d] and only-4-day RJ [O4d]) were determined. Significant differences in levels of moisture, protein, 10-hydroxy-2-decenoic acid (10-HDA), fructose (F) and glucose (G) were found between the RJ and WJ samples. The nutrient content was significantly higher in samples on O2d than the O3d and O4d samples. The results of this study add to the current knowledge of the nutritional value of RJ and WJ. These results also imply a strong relationship between nutritional effects and polyphenism in honey bees.chemical / composition / royal jelly / worker jelly

“…The amount of imidacloprid consumed by honeybees is determined by the following equivalence: 1 mg of sugar contained in nectar or honey = 4.75 pg of imidacloprid and 1 mg of pollen = 3.4 pg of imidacloprid in nectar and pollen coming from Gaucho ® seed-dressed plants. N Larvae consume royal jelly, produced by nurses, which contains honey and pollen (Haydak, 1943(Haydak, , 1968(Haydak, , 1970Kunert and Crailsheim, 1988;Malone et al, 2002).…”

Modes of honeybees exposure to systemic insecticides: estimated amounts of contaminated pollen and nectar consumed by different categories of bees

et al. 2005

-The hazard posed to honeybees by systemic insecticides is determined by toxicity tests that are designed to study the effects of insecticides applied on the aerial parts of plants, but are not adapted to systemic substances used as soil or seed treatments. Based on the available data found in the literature, this paper proposes modes of honeybees exposure to systemic insecticides by estimating their pollen and nectar consumption. Estimates are given for larvae and for the categories of adults which consume the highest amounts ofpollen, the nurse bees, and -nectar, the wax-producing bees, the brood attending bees, the winter bees, and the foraging bees. As a case study, we illustrate these estimates with the example of imidacloprid because its concentrations in sunflower nectar and in sunflower and maize pollens of seed-dressed plants have been precisely determined, and because its levels of lethal, sublethal, acute, and chronic toxicities have been extensively investigated.Apis mellifera / systemic insecticide / exposure / imidacloprid / nectar / pollen

“…Some authors (Sturtevant, 1924;Rinderer and Rothenbuhler, 1974) have the opinion, that the resistance of larvae against AFB has something to do with the chemical composition of larval food and its changes during larval development (Haydak, 1943). For example, Sturtevant found that the food of the older larvae contained a higher percentage of reducing sugar which was derived from honey or nectar, and that a concentration of reducing sugar of approximately 3 to 4 per cent or more in the larval intestine was more than sufficient to inhibit the growth of P. larvae larvae spores.…”

“…Woodrow and Holst (1942) demonstrated that larvae older than two days were less susceptible to an infection with AFB. Haydak (1943) showed that the composition of the larval food changed during larval development. On the basis of these two facts, it was assumed that there was a connection between larval food and resistance.…”

-Paenibacillus larvae larvae, a Gram-positive and spore-forming bacterium, is the cause of American foulbrood. We investigated the resistance of larvae of different ages from different colonies against P. larvae larvae. We prepared ethanol-water-extracts from two, three, four and five day old larvae and also larvae in two capped stages to test the ability of the homogenates to inhibit the growth of P. larvae larvae in vitro. There were age and colony dependent differences in the inhibiting potentials of larvae. The results suggest that the concentration of the inhibiting substance(s) in the extract might be responsible for the known different degree of resistance against P. larvae larvae in vivo. Our results further show that the extracts of the two-, three-and four-day-old larvae have the ability to inhibit the growth of P. larvae larvae very well, while starting around day five the inhibiting effect is gradually reduced.Apis mellifera carnica / Paenibacillus larvae larvae / honeybee larvae / age-related resistance /
