The potency of various bee antigens including bee venom, several whole bee body extracts and fractions of bee venom was studied using the RAST inhibition method. As compared to whole bee body extract, bee venom was a much more potent inhibitor of both bee venom and whole body RAST, suggesting that venom has a greater capacity to bind specific bee IgE antibodies. Whole body extracts also varied ...

acute bee paralysis virus (abpv) is a small single stranded rna virus recently classified within the family dicistroviridae, genus cripavirus. here, we describe the first study of abpv in unhealthy bee colonies, which has been an unusual loss in adult bee population and significant honey bee mortality during the year. the aim of this study was evaluation of abpv infection in honey bee colonies ...

abstract— in this paper we have tried to develop an altered version of the artificial bee colony algorithm which is inspired from and combined with the meta-heuristic algorithm of firefly. in this method, we have tried to change the main equation of searching within the original abc algorithm. on this basis, a new combined equation was used for steps of employed bees and onlooker bees. for this...

The Catalogue of Afrotropical Bees provides a comprehensive checklist species bees known from Sub-Saharan Africa and the western Indian Ocean islands, excluding honey bee ( Apis mellifera Linnaeus) (Eardley Urban 2010). has detailed bibliography group, distribution records, biological associations (visited flowers, host plants, plants used as nests, well parasitoids). database, which was origin...

The diversity of species is striking, but can be far exceeded by the chemical diversity of compounds collected, produced or used by them. Here, we relate the specificity of plant-consumer interactions to chemical diversity applying a comparative network analysis to both levels. Chemical diversity was explored for interactions between tropical stingless bees and plant resins, which bees collect ...

We report the first discovery and genome sequence of a virus infecting the red imported fire ant, Solenopsis invicta. The 8026 nucleotide, polyadenylated, RNA genome encoded two large open reading frames (ORF1 and ORF2), flanked and separated by 27, 223, and 171 nucleotide untranslated regions, respectively. The predicted amino acid sequence of the 5' proximal ORF1 (nucleotides 28 to 4218) exhi...

Ants known for attacking and killing hatchling birds and reptiles include the red imported fire ant (Solenopsis invicta Buren), tropical fire ant [Solenopsis geminata (Fabr.)], and little fire ant [Wasmannia auropunctata (Roger)]. We tested whether sea turtle nest placement influenced exposure to predaceous ants. In 2000 and 2001, we surveyed ants along a Florida beach where green turtles (Chel...

Abstract Schwarziana bees are a ground-nesting stingless bee distributed in the Neotropical region. quadripunctata was first described and most studied species of this genus. Now, there four valid bees, but it has been suggested that diversity taxon may be higher, due to undescribed cryptic species. In study, we investigated populational S. using workers collected at 11 localities Brazil (from ...
