Apis mellifera ligustica and A. cerana cerana exhibit differences in olfactory sensitivity to odors from nectariferous plants and diseased broods. It is presumed that the differences in odorant-binding proteins (OBPs) between these 2 species contribute to their olfactory sensitivity. We compared the sequences, temporal expression pattern, and binding properties of the 2 OBP-encoding genes. We c...
Abstract We present an analysis of the structure Fejes Tóth cells in natural combs Chinese bee, Apis cerana (Hymenoptera: Apidae), and Italian mellifera ligustica Apidae). The proportion built by bee colonies was determined. Molds three-rhombus were used to measure various structural parameters, such as diameter depth cells. Both bees average no more than 18% on combs. dihedral angle two hexago...
The effects of Bt Cry1Ah toxin on worker honeybees (Apis mellifera ligustica and Apis cerana cerana)
objectives: royal jelly (rj), a secretion of both the hypopharyngeal and mandibular glands of nurse workers, is believed to play a central role in honeybee queen development. important component of royal jelly are proteins which form about 50% of the dry mass of rj. major royal jelly proteins (mrjps) are the dominant proteinaceous component of royal jelly and constitute about 82-90% of total pr...
Mitochondrial DNA sequence variation can be used to infer honey bee evolutionary relationships. We examined DNA sequence diversity in the cytochrome C oxidase I (COI or Cox1) gene segment of the mitochondrial genome in 112 samples of Apis mellifera from 15 different populations in Turkey. Six novel haplotypes were found for the COI gene segment. There were eight variable sites in the COI g...
Bifidobacteria are known as anaerobic/microaerophilic and fermentative microorganisms, which commonly inhabit the gastrointestinal tract of various animals and insects. Analysis of the 2,167,301 bp genome of Bifidobacterium asteroides PRL2011, a strain isolated from the hindgut of Apis mellifera var. ligustica, commonly known as the honey bee, revealed its predicted capability for respiratory m...
Samples from nine populations belonging to three African (intermissa, scutellata and capensis) and four European (mellifera, ligustica, carnica and cecropia) Apis mellifera subspecies were scored for seven microsatellite loci. A large amount of genetic variation (between seven and 30 alleles per locus) was detected. Average heterozygosity and average number of alleles were significantly higher ...
The honeybee population of the tropical Reunion Island is a genetic admixture of the Apis mellifera unicolor subspecies, originally described in Madagascar, and of European subspecies, mainly A. m. carnica and A. m. ligustica, regularly imported to the island since the late 19th century. We took advantage of this population to study genetic admixing of the tropical-adapted indigenous and temper...
