Worker life tables, survivorship, and longevity in colonies of Bombus (Fervidobombus) atratus (Hymenoptera: Apidae).
Survivorship curves and longevity of workers were studied in two queenright and two queenless colonies of Bombus (Fervidobombus) atratus. Survivorship curves for workers of all colonies were, in general, convex, indicating an increasing mortality rate with increasing age. The mean longevity for the workers from queenright colonies, 24.3 days and 17.6 days, was not significantly different from t...
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 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. 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 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 کاملSpecies status of Bombus monticola Smith (Hymenoptera: Apidae) supported by DNA barcoding.
Certain species of bumblebees are difficult to distinguish based on morphology alone due to a lack of diagnostic characters and extensive intraspecific variation in colour patterns. The discussion concerning whether Bombus lapponicus and Bombus monticola are the same species or not, seems to be ongoing. We present a study of 16 speciemens of B. monticola/B. lapponicus from Norway, identified wi...
