The basic regularities connections that affect the productivity of bees developing. Established dynamics of the main fatty acids parameters pollen depending on the period of collection. The regularities of the influence of the fatty acids composition of pollen on the development of bee colonies.
It was studying bee pollen for fattyacid composition during flowering of differents pecies of pollen from Aprilto Augustin 2008 and 2010, and identified the needs of the averagerate for bees Easternregion. To complete the task were selected samples of beepollen Polyphlore dust, on private apiary Moyseenko, in the Kharkiv region Volchansky district polliniferous season for three years. The collected experimental material was crusheding rinders of «Cyclone» to 0,1 mm. The lipid extraction was performed with a mixture of chloroform-methanol, hydrochloricacid, followed methylation sodium methylate.
To identifymethy lesters of fattyacid susinggas-liquid chromatograph «Chrom – 5». It was considered the,change linoleic, linolenic, oleic essential fatty acids separately and built for them polynomial trend line (approximation and smoothing), which allowed the correct concentration of fatty acids for normal development bees in Eastern Ukraine in spring and summer.
The material indicate that bees pollen has different dynamics of fatty acids, which is observed with seasonal variations and differences between years. Most fatty acids enriched bee pollen was at when the late spring and early summer. Analyzing the quality of pollen brought by bees, it should be noted that the period of most intensive growth of bee colonies coincides with intensive offering of pollen with high levels of fatty acids.

Key words: bee’s pollen, quality bee’s pollen, fatty acids indicators, essential fatty acids, oleic acid, linoleic acid, linolenic acid, development of bee’s colonies.
