0.05). In fourth and mean of periods, the highest populations of colonies were belonging to the Met/Lys group (12.6 and 9.42 frame, respectively) and the lowest population (10.4 and 8.19 frame, respectively) was belonging to the control. In all of periods, Laying performance of queens was increased significantly by feeding Met/Lys compared to the control (P < 0. 05). For brood rearing and honey production, the best performance was obtained by colonies supplemented with Met/Lys treatment as well. In overall, our study confirms the positive effectiveness of feeding Met/Lys on population size, laying performance of queens and honey production.]]>

0/05). Clustering results also showed that, the occurrence points of genus members is placed in two clusters, cluster 1 in the north of Iran and cluster 2 along of Zagros mountain range. There is similarities between two clusters. Two variables include the annual rainfall and soil temperature at depths of 10 to 40 cm have the most effect on the distribution of genus Niphargus. The results also showed that due to distance from the ground surface and the environmental variables, the same conditions exist in most occurrence points of this taxon.]]>
