Highly toxic chemicals are widely used in agriculture to combat diseases and pests of crop plants or forest area . This paper aims to demonstrate he impact on the bees of the pesticides treatment used on agricultural entomophilous crops, bees that are their main pollinator. It is also researching measures to protect bee families and humans against poisoning with pesticides. The honey bee has considerable economic importance and is indirectly of great interest, through the benefits it brings to the agricultural field through through crop pollination (rape, mustard, sun flower, etc.).Bees play an important role in the pollination of the most crop batches destined for seed production. From the conducted research, the year 2006 was the most favorable for the bees, because in April, the melliferous plants benefited from better weather conditions, compared to the other years.  In the third week after the pesticide treatment, the number of bees has fallen sharply from a maximum of 313 bees recorded in the second week to a minimum of 52 bees in the third week and after another 12 days, after insecticide application, that is, in the fourth week, there was again a maximum of 382 bees. The amount of brood reared in the reference period ranged from 1090 cm 2 and 544 cm 2 and   was dependent on the pesticides used in the rape culture and on climate . After the statistical processing of the data a link is observed between the amount of brood as a dependent variable and the number of bees, a proven low value of Pearson correlation coefficients (0.598 to 0.615) and determination of R-Square (0.358-0.378), with the guarantee of experimental results within the acceptable coefficient of 5% given by the  Sig. coefficient, i.e. 4%.
