摘要:

A pollen calendar of traditionally produced honeys in Gaya/southern Niger was established for a two year period. The region is situated in the transition zone from the sahelian to the sudanian savannas. In this area honey represents an appreciated source for further income for the cultivators. Palynological investigations of the honey samples showed that the bees regularly exploit a restricted number of trees and bushes, such asCombretum, TerminaliaorGuierathroughout the whole year orLannaea, ParkiaandBombaxduring the winter and spring. Other Sudanian trees and bushes are only occasionally visited in addition. During the dry season Gramineae are also exploited because of the sap provided by the Aphids. In their pollen spectra the honeys reflect both the vegetation types and the agrarian systems of the region as for as can be traced from their collection time and from observations on the flowering period of the trees and bushes visited.
