Two similar<br />batches of bee colonies were created. The first batch of 20 colonies was put in horizontal hives and second batch with<br />25 colonies– in vertical hives. The main sources of honey in the area were: Acacia, Linden tree and spontaneous flora.<br />In beekeeping season of 2011 have been studied main biological and morpho productive characters of bee colonies,<br />such as: colony strengthens, resistance to overwinter and diseases, queens prolificacy, brood viability, total quantity of<br />honey collected in nest after harvest. Appreciation of morpho productive characters was done according to our<br />methodology developed by the new zootechnic regulation according to bee colonies valuation, growing and<br />certification of genitor beekeeping materials, approved by decision of Government of Republic of Moldova no. 306 of<br />28.04.2011. It was found that the types of hives, where were housed the experimental bees, all other equal conditions of<br />maintenance and exploitation, have not had any impact on the biological process of bees overwinter. This is confirmed<br />by the fact that the average strengthens of bee colonies in both experimental groups, being equal at the beginning of<br />experiment (1,78 kg in the autumn of 2010, in entry of overwinter) remained same in spring of 2011 (1,49 kg out of the<br />winter). Therefore, overwinter resistance of bee colonies in both groups was also identical, averaging 83.1%. At the<br />same time, the hive types, tested in experiment, had a significant influence on reproduction process and development of<br />bee colonies in high beekeeping season. Thus, the queens prolificacy from 2nd batch with bee colonies located in<br />vertical hives during the season, was higher compared to the Ist batch, accommodated in vertical hives, with 60 eggs/24<br />hours, or with 3.5% (B > 0.95). A better prolificacy activity of queens in vertical hives can be explained, in our view,<br />by the fact that they have a better comfort of laying, compared with those from horizontal hives. We found that in<br />horizontal hives, queens prefer for laying the area near bee entrance and it is explained by the fact that this place is<br />better aired and ensure the brood with sufficient oxygen. In vertical hives queens laying is more uniform and it is<br />spread on more honeycombs. This is due to a better and uniform ventilation in entire hive, which gives enough oxygen<br />to brood. All this, has led to an active laying of queens from vertical hives, also to a bigger amount of capped brood<br />and as a result, essential increase of bee colony strengthens. At the beginning of first harvest (locust tree), bee colonies<br />placed in vertical hives reclaimed at a bigger rate than those placed in horizontal hives. Regarding bee colonies<br />strengthens, those from 2nd batch exceeded significant, at this stage, those from 1st batch, with 0.33 kg or 9,4% (B ><br />0,99). Bee colonies from vertical hives entered overwinter significantly more powerful than bees from horizontal hives,<br />which creates premises for a stronger development and better productivity in the next beekeeping season. Due to a<br />quicker development, bee colonies kept in vertical hives accumulated, during active season, a bigger quantity of honey<br />in the nest. Thus, the total quantity of honey accumulated in nest, bee families maintained in vertical hives have<br />significantly exceeded those from horizontal hives with 7.5 kg, or 19,1% (B > 0.999). Economic effect obtained at<br />exploitation of vertical hives only from honey production is 375 MD lei, or 23.8 euro per bee colony. Based on<br />obtained results were made following conclusions. 1. Vertical hives compared to horizontal hives, offer to bee colony<br />more comfortable biological conditions. 2. Maintenance of bee colonies in vertical hives ensures an increase of queens<br />laying -3.5% and of average annual strengthens of the bee colony – with 6.0%. 3. Use of vertical hives contributes to<br />increasing of honey production with 19.1%. 4. Bee colonies exploitation in vertical hives ensures economic efficiency<br />at least 23.8 euro per bee colony.</p></dc:description> <dc:source>Scientific Papers Series D.
