Pigmentation of Some Honeybee, Apis Mellifera L., Products
Some floral pigments (including antioxidants); carotenoids, chlorophylls, anthocyanins and xanthophylls were determined colorimetrically in some honeybee, Apis mellifera L., products; citrus, clover and cotton honeys, three types of beeswax; white, brown and dark and propolis; brown, dark brown and dark. Two solvents (acetone or ethanol) were used for extraction and determination of pigments at...
متن کاملProteomic Analysis of Honeybee (Apis mellifera L.) Pupae Head Development
The honeybee pupae development influences its future adult condition as well as honey and royal jelly productions. However, the molecular mechanism that regulates honeybee pupae head metamorphosis is still poorly understood. To further our understand of the associated molecular mechanism, we investigated the protein change of the honeybee pupae head at 5 time-points using 2-D electrophoresis, m...
متن کاملMale fitness of honeybee colonies (Apis mellifera L.).
Honeybees (Apis mellifera L.) have an extreme polyandrous mating system. Worker offspring of 19 naturally mated queens was genotyped with DNA microsatellites, to estimate male reproductive success of 16 drone producing colonies. This allowed for estimating the male mating success on both the colony level and the level of individual drones. The experiment was conducted in a closed population on ...
متن کاملEstablishment of a Bacterial Infection Model Using the European Honeybee, Apis mellifera L
Injection of human pathogenic bacteria (Pseudomonas aeruginosa, Serratia marcescens, Salmonella enterica, Staphylococcus aureus, and Listeria monocytogenes) into the hemocoel of honeybee (Apis mellifera L.) workers kills the infected bees. The bee-killing effects of the pathogens were affected by temperature, and the LD₅₀ values at 37°C were more than 100-fold lower than those at 15°C. Gene-dis...
متن کاملOlfactory detectability of L-amino acids in the European honeybee (Apis mellifera).
The honeybee is one of several insect model systems for the study of olfaction, yet our knowledge regarding the spectrum of odorants detectable by Apis mellifera is limited. One class of odorants that has never been tested so far are the amino acids, which are important constituents of floral nectar. Using the proboscis extension response paradigm, we assessed whether the odor of amino acids is...
