  • Flowering of species with apicultural importance in the northwest of Chubut (Argentina).With the aim of providing information about the availability of resources used by Apis mellifera L., theflowering phenology of 110 species of apicultural importance was recorded in the northwest of Chubut during2003, 2004 and 2005. The plants studied were selected by taking into account previous melissopalynologicalresearches, as well as observations of the activity carried out by Apis mellifera on these plants. The registeredphenophases were: a) beginning of flowering b) full flowering c) end of flowering and beginning of fructification.In all these cases the frequency of visits of Apis mellifera was recorded. From the total of species recorded, 48are native plants, 56 are naturalized plants and 6 are cultivated. All the flowerings observed correspond to aperiod that extends from the beginning of September to April. The major flowering offer was recorded in Decemberand in the first fortnight of January, when the highest number of species was in full flowering. The familiesmostly used by Apis mellifera were: Asteraceae, Fabaceae, Rosaceae, Rhamnaceae y Brassicaceae. The nativeplants mostly visited were: Aristotelia chilensis (Molina) Stuntz, Buddleja globosa Hope, Colletia hystrix Closs.,Discaria trinervis (Gillies) Reiche, Discaria articulata (Phil.)
