Systematical 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. This was carried out on 133 females and 42 males which were collected from various localities in Turkey. After digitizing landmarks on the right fore wings, 2-dimensional Cartes...
متن کاملThe bumblebees of North China (Apidae, Bombus Latreille).
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 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 ...
متن کاملPhotoreceptor Spectral Sensitivity in the Bumblebee, Bombus impatiens (Hymenoptera: Apidae)
The bumblebee Bombus impatiens is increasingly used as a model in comparative studies of colour vision, or in behavioural studies relying on perceptual discrimination of colour. However, full spectral sensitivity data on the photoreceptor inputs underlying colour vision are not available for B. impatiens. Since most known bee species are trichromatic, with photoreceptor spectral sensitivity pea...
متن کاملGenetic structure of Asian populations of Bombus ignitus (Hymenoptera: Apidae).
The genetic structure of seven mainland and island Asian populations of Bombus ignitus was investigated using nine microsatellite markers and the sequences of part of the mitochondrial cytochrome b (cytb) gene. While microsatellite markers showed high genetic variability, no sequence variation was found in the cytb gene fragment analyzed. The number of microsatellite alleles ranged from 9 to 24...
