We evaluated the influence of weather variables and habitat type on number nests giant honey bee, Apis dorsata in Nepal. From 2011 to 2014, we counted colonies settled water towers six localities each month. The relationship between average temperature, relative humidity, precipitation was with a generalized additive mixed model. Additionally, nest quantity two types habitats (peri-urban vs. ru...

Solitary bees are important but declining wild pollinators. During daily foraging in agricultural landscapes, they encounter a mosaic of patches with nest and foraging habitat and unsuitable matrix. It is insufficiently clear how spatial allocation of nesting and foraging resources and foraging traits of bees affect their daily foraging performance. We investigated potential brood cell construc...

Abstract This study’s purpose was to make an overview of how ants, bees, wasps, and their products, such as honey are utilized, perceived, experienced in daily life across sub-Saharan Africa. Ethno-entomological information collected by interviews with more than 300 people from 27 countries literature studies. Queens the ant Carebara vidua deliberately eaten unintentionally bee larvae sugar ant...

Although most of the wild bee species are ground-nesting, little is known about their nesting requirements and conservation measures to promote ground-nesting bees. Calcareous grasslands one species-rich habitats in Central Europe therefore essential for protecting diversity. The management practices calcareous so far often focused on plant populations, but order support declining insect additi...

Recent developments in social insect research have challenged the need for close kinship as a prerequisite for the evolution of stable group living. In a model communal bee species, Lasioglossum (Chilalictus) hemichalceum, previous allozyme work indicated that groups of cooperating adult females are not relatives. Yet at any given time, not all group members perform the risky task of foraging. ...

Introduction Primitively eusocial halictid bees are excellent systems to study the origin of eusociality, because all individuals have retained the ancestral ability to breed independently. In the sweat bee Halictus scabiosae, foundresses overwinter, establish nests and rear a first brood by mass-provisioning each offspring with pollen and nectar. The mothers may thus manipulate the phenotype o...

Most rare species appear to be specialists in plant-pollinator networks. This observation could result either from real ecological processes or from sampling artifacts. Several methods have been proposed to overcome these artifacts, but they have the limitation of being based on visitation data, causing interactions involving rare visitor species to remain undersampled. We propose the analysis ...
