Bumblebees are important pollinators for wild flowers and agricultural crops. North China is a region of varied geomorphology and vegetation, with plateaus, plains, mountains and deserts, and is part of the greatest hotspot of bumblebee diversity worldwide. We report on a field survey of the bumblebees of North China made between 2005-2012. A sample of 21,636 bumblebee specimens are assigned to...
متن کاملAtypical secretions of the male cephalic labial glands in bumblebees: the case of Bombus (Rhodobombus) mesomelas Gerstaecker (Hymenoptera, Apidae).
In bumblebees, the male secretion of the cephalic labial gland is species-specific. It is highly involved in the nuptial behavior, acting as a sexual attracting pheromone.

All the remaining bee species are most likely accidental introductions that arrived after human colonization ...
متن کاملSystematical studies on the species of the subgenus Bombus (Thoracobombus) (Hymenoptera: Apidae, Bombus Latreille) in Turkey.
The aim of this study was to analyze the 12 species which belong to the subgenus Bombus (Thoracobombus) by identifying, collating and testing the applicability of geometrics morphometrics for distinguishing the species.

متن کاملHoming ability of the bumblebee Bombus terrestris (Hymenoptera: Apidae)
The ability of bumblebees to locate their nest site following artificial displacement was investigated. Bombus terrestris (Hymenoptera: Apidae) workers were marked with numbered tags and displaced up to 15 km from their nest. Bees returned from distances of up to 9.8 km, with the proportion of bees returning declining with distance of the release site from the nest. Bees were slow to return to ...
