1- MSc. East Azarbaijan Research Center for Agriculture and Natural Resources In this research 10 honey bee colonies were purchased from apiaries of province, randomly and maintained throughout the research period in stationary apiary. The colonies initially have had young queens and no acaracide treatment was applied to them for 1 last year. Population dynamics of honey bee and Varroa destructor were determined for 7 months (early spring to early autumn 2007) monthly measuring of adult and pupa population and their infestation rate to varroa mite. The Results showed that mite infestation rate of adult bees and pupas gradually increased from May to December 2007. The Pearson R coefficient was calculated to estimate association between specific variables. There is a significantly negative correlation between number of pupas and their infestation values to varroa(r = -0.325, p<0.006); demonstrating that the lower the number of pupas the higher the infestation rate of each pupa. This relationship was not found between adults and their infestation rate(r = -0.031, p<0.801). Infestation rate of adult bees and pupas have had a significantly positive relationship(r = 0.355, p<0.003). There were no correlation between the number of adult bees and infestation rate of pupas and vise versa(r = -0.089, p<0.464; r = -0.216, p<0.072).

Sُُc student of Islamic Azad university (Ghaemshahr branch) - Apicultural Society of Iran Khojir National Park with 9380ha space is situated in 35° north latitude and 51° east longitude and 1547m altitude from sea. The highest altitude from the sea is 2600m and the lowest of it is 1450m. Whole the area except its north east part is under protection the environment government. Unknowing the new scientific methods and the attractive plants for honeybee and kinds of using for it, is caused many difficult for the beekeepers. Thus, for solving these problems, at first the plants of the region were recognized. For this purpose the plants which had been distributed in Jajrood Watershed, the area of Researches Center of Tehran Province and around the beehives of Animal Sciences Research Institute of Iran, were collected and transported to Herbarium of the institute for recognizing. Results showed that 22 Family include 71 species are existed in the region. The most important family is Compositae with 15 species (21%) and after it the important families are orderly consist of Leguminosae with 13 species (18%), Labiatae with 9 species (13%), Rosaceae with 9 species (13%) and the other families with 25 species (35%) are in further steps. In this study plant species in point of using for honeybee were categorized to 3 groups inclusive nectar plants (20%), pollen plants (32%) and nectar-pollen plants (48%).
