Pollination of two oil-producing plant species: Camelina (Camelina sativa L. Crantz) and pennycress (Thlaspi arvense L.) double-cropping in Germany
Camelina and pennycress are two annual oil-producing plant species that have recently gained attention as biofuel feedstock crops. Prior to commercial production, information on their breeding and pollination system is essential to ensure sustainable management. We conducted pollination experiments and observed flower visitors in an experimental double-cropping system in southern Germany. We fo...
متن کاملA User-Centred Design Approach Towards Developing an Intelligent Living Environment for Honeybees
The honeybee (Apis mellifera) is of vital importance both to humankind and the wider ecosystem, primarily because of its major role as a pollinator of crops and a wide range of other flowering plants. However, over recent years, honeybees have been suffering a terrible decline in numbers, due to a variety of factors including parasites and diseases (including the varroa mite and European and Am...
متن کاملDecline and conservation of bumble bees.
Declines in bumble bee species in the past 60 years are well documented in Europe, where they are driven primarily by habitat loss and declines in floral abundance and diversity resulting from agricultural intensification. Impacts of habitat degradation and fragmentation are likely to be compounded by the social nature of bumble bees and their largely monogamous breeding system, which renders t...
متن کاملQueens become workers: pesticides alter caste differentiation in bees
Bees are important for the world biodiversity and economy because they provide key pollination services in forests and crops. However, pesticide use in crops has adversely affected (decreased) queen production because of increased mortality among larvae. Here, we demonstrated that in vitro-reared queens of a neotropical social bee species (Plebeia droryana) also showed high larval mortality aft...
متن کاملاستفاده از خصوصیات الکتروفورتیک پروتئین های قفس سینه در تفکیک جمعیتهای زنبور عسل نژاد ایرانی
An important and fundamental step in breeding honeybees is the separation of honeybee populations in Iran. During the years 1992-1996, several research works were directed towards the investigation of genetic populations of the Iranian honeybee (Apis mellifera L.), using biochemical methods. For this purpose, samples of worker bees were taken from 251 colonies of 115 apiaries in 84 cities in 21...
