The male genetalia of described first Anthophorine genus in 1802 different Anthophorine bees vary distinctly and in 1803 he proposed the name (Brooks, 1988). They frequently bear metallic Anthophora. Fabricius named a genus as blue or green pubescent bands on metasomal Megilla in 1805. The name Megilla is now terga. They fly in summer. This genus regarded as a junior synonym of Anthophora includes 12 sub genera and 253 species by Michener, (1974). Anthophorine bees are (Brooks, 1988). The genus Amegilla is a now grouped under the family Apidae, sub diverse group of approximately 255 family Apinae and tribe Anthophorini Anthophorine bee species distributed in 580 Int.J.Curr.Microbiol.App.Sci (2019) 8(7): 580-587 southern Europe and Mediterranean basin Amegilla in his revision of Egyptian southward throughout Africa and Madagascar Anthophora species Engel (2007) described east into Arabia and in Asia as far as northeast new species of Amegilla from northeastern China, India, Sri Lanka, Indonesia, New Egypt viz., Amegilla argophenax and Guinea as well as Australia (Engel, 2007).

These diferent behavioral phenotypes can expose animals to distinct cognitive challenges, which may be addressed through neuroanatomical diferentiation. The dramatic phenotypic plasticity underlying ARTs provides a powerful opportunity to study how intraspecifc nervous system variation can support distinct cognitive abilities. We hypothesized that conspecifc animals pursuing ARTs would exhibit dissimilar brain architecture. Dimorphic males of the bee species Centris pallida and Amegilla dawsoni use alternative mate location strategies that rely primarily on either olfaction (large-morph) or vision (small-morph) to fnd females. This variation in behavior led us to predict increased volumes of the brain regions supporting their primarily chemosensory or visual mate location strategies. Large-morph males relying mainly on olfaction had relatively larger antennal lobes and relatively smaller optic lobes than small-morph males relying primarily on visual cues. In both species, as relative volumes of the optic lobe increased, the relative volume of the antennal lobe decreased. In addition, A. dawsoni large males had relatively larger mushroom body lips, which process olfactory inputs.

  • Food Load Manipulation Ability Shapes Flight Morphology in Females Of
    Polidori et al. Frontiers in Zoology 2013, 10:36 http://www.frontiersinzoology.com/content/10/1/36 RESEARCH Open Access Food load manipulation ability shapes flight morphology in females of central-place foraging Hymenoptera Carlo Polidori1*, Angelica Crottini2, Lidia Della Venezia3,5, Jesús Selfa4, Nicola Saino5 and Diego Rubolini5 Abstract Background: Ecological constraints related to foraging are expected to affect the evolution of morphological traits relevant to food capture, manipulation and transport. Females of central-place foraging Hymenoptera vary in their food load manipulation ability. Bees and social wasps modulate the amount of food taken per foraging trip (in terms of e.g. number of pollen grains or parts of prey), while solitary wasps carry exclusively entire prey items. We hypothesized that the foraging constraints acting on females of the latter species, imposed by the upper limit to the load size they are able to transport in flight, should promote the evolution of a greater load-lifting capacity and manoeuvrability, specifically in terms of greater flight muscle to body mass ratio and lower wing loading. Results: Our comparative study of 28 species confirms that, accounting for shared ancestry, female flight muscle ratio was significantly higher and wing loading lower in species taking entire prey compared to those that are able to modulate load size. Body mass had no effect on flight muscle ratio, though it strongly and negatively co-varied with wing loading. Across species, flight muscle ratio and wing loading were negatively correlated, suggesting coevolution of these traits. Conclusions: Natural selection has led to the coevolution of resource load manipulation ability and morphological traits affecting flying ability with additional loads in females of central-place foraging Hymenoptera.

  • Molecular Ecology and Social Evolution of the Eastern Carpenter Bee
    Molecular ecology and social evolution of the eastern carpenter bee, Xylocopa virginica Jessica L. Vickruck, B.Sc., M.Sc. Department of Biological Sciences Submitted in partial fulfillment of the requirements for the degree of PhD Faculty of Mathematics and Science, Brock University St. Catharines, Ontario © 2017 Abstract Bees are extremely valuable models in both ecology and evolutionary biology. Their link to agriculture and sensitivity to climate change make them an excellent group to examine how anthropogenic disturbance can affect how genes flow through populations. In addition, many bees demonstrate behavioural flexibility, making certain species excellent models with which to study the evolution of social groups. This thesis studies the molecular ecology and social evolution of one such bee, the eastern carpenter bee, Xylocopa virginica. As a generalist native pollinator that nests almost exclusively in milled lumber, anthropogenic disturbance and climate change have the power to drastically alter how genes flow through eastern carpenter bee populations. In addition, X. virginica is facultatively social and is an excellent organism to examine how species evolve from solitary to group living. Across their range of eastern North America, X. virginica appears to be structured into three main subpopulations: a northern group, a western group and a core group. Population genetic analyses suggest that the northern and potentially the western group represent recent range expansions. Climate data also suggest that summer and winter temperatures describe a significant amount of the genetic differentiation seen across their range. Taken together, this suggests that climate warming may have allowed eastern carpenter bees to expand their range northward. Despite nesting predominantly in disturbed areas, eastern carpenter bees have adapted to newly available habitat and appear to be thriving.

Chairperson Michael S. Engel Charles D. Michener Edward O. Wiley Kirsten Jensen J. Christopher Brown Date Defended: November 10, 2010 The Dissertation Committee for Ismael Alejandro Hinojosa Díaz certifies that this is the approved version of the following dissertation: Comparative Genital Morphology, Phylogeny, and Classification of the Orchid Bee Genus Euglossa Latreille (Hymenoptera: Apidae), with Distributional Modeling of Adventive Euglossines Chairperson Michael S. Engel Date approved: November 22, 2010 ii ABSTRACT Orchid bees (tribe Euglossini) are conspicuous members of the corbiculate bees owing to their metallic coloration, long labiomaxillary complex, and the fragrance-collecting behavior of the males, more prominently (but not restricted) from orchid flowers (hence the name of the group). They are the only corbiculate tribe that is exclusively Neotropical and without eusocial members. Of the five genera in the tribe, Euglossa Latreille is the most diverse with around 120 species. Taxonomic work on this genus has been linked historically to the noteworthy secondary sexual characters of the males, which combined with the other notable external features, served as a basis for the subgeneric classification commonly employed. The six subgenera Dasystilbe Dressler, Euglossa sensu stricto, Euglossella Moure, Glossura Cockerell, Glossurella Dressler and Glossuropoda Moure, although functional for the most part, showed some intergradations (especially the last three), and no phylogenetic evaluation of their validity has been produced.

Hymenoptera, Apidae, microsatellite development, Anthophora plumipes, 454 sequencing, Anthophorini Abstract. Novel microsatellite markers for the solitary bee, Anthophora plumipes, were identified and characterised using 454 GS-FLX Titanium pyrosequencing technology. Thirty seven loci were tested using fluorescently labelled primers on a sample of 20 females from Prague. The number of alleles ranged from 1 to 10 (with a mean of 4 alleles per locus), resulting in an observed hetero- zygosity ranging from 0.05 to 0.9 and an expected heterozygosity from 0.097 to 0.887. None of the loci showed a significant devia- tion from the Hardy-Weinberg equilibrium and only two loci showed the significant presence of null alleles. No linkage between loci was detected. We further provide information on a single multiplex PCR consisting of 11 of the most polymorphic loci. This multi- plex approach provides an effective analytical tool for analysing genetic structure and carrying out parental analyses on Anthophora populations. Most of the 37 loci tested also showed robust amplification in five other Anthophora species (A. aestivalis, A. crinipes, A. plagiata, A. pubescens and A. quadrimaculata).

  • The Foraging Preferences of the Hairy-Footed Flower Bee (Anthophora Plumipes (Pallas 1772) in a Surburban Garden
    THE FORAGING PREFERENCES OF THE HAIRY-FOOTED FLOWER BEE (ANTHOPHORA PLUMIPES (PALLAS 1772) IN A SURBURBAN GARDEN Maggie Frankum, 3 Chapel Lane, Knighton, Leicester LE2 3WF PREAMBLE This paper is based on a project carried out as a requirement of a three-year Diploma in Applied Ecology at the University of Leicester (1997). The original report is extensively illustrated and stretches to 85 pages. This paper attempts to distill the main findings of the research. It is hoped that it will stimulate other entomologists in the county to carry out basic research literally on their own doorstep. INTRODUCTION In springtime, with the onset of warmer weather, the foraging activities of social bumblebees such as Bombus pratorum, B pascuorum, B hortorum, B terrestris and B lapidarius, are fairly commonplace in suburban gardens. The first big queens emerge from hibernation to establish their nests and produce new worker bees. However, there are other species of bees that are less noticeable until some particular behaviour pattern draws attention to them.
