Project description:Apis mellifera syriaca is the native honeybee subspecies of Jordan and much of the Middle East. It expresses behavioral adaptations to a regional climate with very high temperatures, nectar dearth in summer, attacks of the Oriental wasp Vespa orientalis and in most cases it is resistant to varroa mites. The Thorax control sample of A. m. syriaca in this experiment was originally collected and stored since 2001 from Wadi Ben Hammad a remote valley in the southern region of Jordan. Using morphometric and Mitochondrial DNA markers it was proved that bees from this area had show higher similarity than other samples collected from the Middle East as represented by reference samples collected in 1952 by Brother Adam. The samples L1-L5 are collected from the National Center for Agricultural Research and Extension breading apiary which was originally established for the conservation of Apis mellifera syriaca. Goal was to use the genetic information in the breeding for varroa resistant bees and to determine the successfulness of this conservation program.

Project description:The honeybee brain is comprised of a nervous system that sufficiently regulates this life transition. Knowledge about how protein phosphorylation functions in regards to the neurobiological activities in the honeybee brain to drive the age-specific labor division is still lacking. Protein phosphorylation, the most common post-translational modification (PTM), is a key switch for rapid on-off control of signaling cascades that regulate cell differentiation and development, enzyme activity and metabolic maintenance in living cells. A fundamental mechanism for regulating signaling network and protein activity is the covalent PTM of serine (Ser), threonine (Thr), and tyrosine (Tyr) residues with phosphate. Fortunately, because of advances in phosphopeptide enrichment and improvements in mass spectrometry (MS) instrumentation and methods, phosphoproteomics has enabled large-scale identification of protein phosphorylation sites and phosphorylation networks in biological samples. Although the proteome has been mapped in the brain of nurse and forager bees, knowledge about age-specific effects of phosphorylation regulation on proteins in the honeybee brain is still lacking. Moreover, information in regards to the honeybee phosphoproteome is also very limited. Only very recently, in-depth phosphoproteomics analyses of protein phosphorylation networks in the hypopharyngealgland of the honeybee have been reported. Although the phosphoproteome analyses during the development of brood and salivary glands has been reported, only very limited proteins were phosphorylated and phosphorylation sites of those phosphoproteins were not assigned. Therefore, a comprehensive characterization of phosphoproteomics and changes in the brains of nurse and forager bees is key to understand the phosphorylation events underlying age-specific physiology to achieve the completion of biological missions in this well-organized social community of the honeybee. Honeybee (A. m. ligustica) colonies used for sampling were raised at the apiary of the Institute of Apicultural Research, Chinese Academy of Agricultural Science, Beijing. Newly emerged (<12 h after emergence) worker bees were marked on their thoraxes and placed back into the colonies to develop and then the marked nurse and forager bees were collected on days 10 and 20, respectively. There were 150 bees sampled from each of the five colonies which have queens at the same age. In brief, for each time point, worker bees were sampled from five colonies, and pooled all samples for further analysis. This procedure was repeated three times, so that we finally ended up with three independent biological replicates per time point, each consisting of 150 honeybees. Then their brains were dissected, and the brain samples were pooled and stored at −80 °C for further analysis. All the colonies were managed with almost identical population, food, and brood during the nectar flow of chaste berry (Vitexnegundo L.) in June.

Project description:Paenibacillus larvae, the causal agent of American Foulbrood disease (AFB), affects honeybee health worldwide. The present study investigates the transcriptional response of this Gram-positive, endospore-forming bacterium to bodily fluids from honeybee larvae. Four different conditions were evaluated with a loop design: sampling of in vitro grown P. larvae cultures one or four hours after addition of larval fluids or BHIT-broth (C1, T1, C4, T4).

Project description:Apis mellifera intermissa (Buttel-Reepen, 1906) is the native honeybee subspecies of Algeria. A.m.intermissa occurs in Tunisia, Algeria and Morocco, between the Atlas and the Mediterranean and Atlantic coasts (Ruttner, 1988), in an area of more than 2500 km long. Intermissa indicates the position through this bee races between tropical Africa and European breeds (Peyvel, 1994). The settlement area of the Tellian extends from Tunisia to Morocco. Ruttner et al (1978) describes the pure Tellian. It is a black hair of his coat poverty brings out the black color. It is a small size, there are some times light illumination on the tergites. This bee is very aggressive, nervous, sick to take part, as swarms huge fall and even produced many brood and can build up to one hundred queen cells (Le Conte, 2002). A.m.intermissa is prone to swarming, shows an aggressive behaviour and an abundant use of propolis (Ruttner 1988). This study is part of the project funded by the USAID Grant No. TA-MOU-08-M29-075.

Project description:To determine the impact of quercetin on honeybee development and physiology, we conducted an RNASeq analysis of gene expression in neonate larvae exposed for three days to control “bee candy” diet (comprising sucrose and sugar syrup) or diets to which 0.1 mM or 0.25 mM quercetin was added.

Project description:In Apis mellifera, the female eggs can develop into workers or queen depending on the diet offered during early development. The outputs of the developed honeybee females are two morphs with particular morphological traits and related physiology. Among the specialized structures in workers the hind tibia forms the corbicula or the pollen basket, a smooth region surrounded by a row of a long scopal hairs, used for carrying pollen and other materials to the nest. This morphological trait and the respective behaviour are absent in queens. Herein we show details of the initial steps of hind legs morphogenesis in honeybee castes. Using results from the hybridization of whole genome-based oligonucleotide arrays with RNA samples from hind leg imaginal discs of pre-pupa honeybees of both castes we present a list of differentially expressed genes.
