Morphological parameters of the component parts of the proboscis of bees Yenisei populations

The proboscis length in bees has great selec-tion, biological and economic value. This sign is important as for collecting nectar, especially for cultures in which nectar is accumulated at the bot-tom of a long tubule of a nimbus, and for pollinator activities of anemophilic plants. In this regard the purpose of this work was studying morphometric parts of proboscis of bees of Central Russian breed of the Yenisei population in Krasnoyarsk Region. In the course of researches features of structural ele-ments system of proboscis of spring and autumn generation from I.I. Melnikov apiaries were studied. (Makovsky rural administration, the villages of Losinoborsk and Sukhanovo) and G.I. Gorchenyov (Podgornovsky rural administration of the Yenisei area), the analysis of morphometric parameters was carried out: the length of mentum, prementum, uvula with a spoon, the width of chin and overall length of proboscis. By the results of researches of morphological parameters of proboscis of Central Russian bees it was established that between bees there were reliable distinctions on separate indica-tors of autumn generation. So, bees from the first bee colonies (Gorchenyov's apiary) authentically differed from bees from other bee colonies on such measurements, as mentum (0.06 mm), chin width (0.08 mm) and the length of proboscis (0.19 mm). Considering winter hardiness, the length of probos-cis of bees of the Yenisei population it was possi-ble to classify them as optimum option of type for keeping and breeding in the conditions of the northern region.
