RESEARCH OBJECTIVES The main objective of the research from this thesis is to establish the effect of some plant infusions and extracts on honeybee colonies from different physiological stages. Regarding the main objective, following actions were made: Experimental lots establishment, carefully following an uniform distribution of the colonies considering their force; Alcoholic and aqueous extracts testing from plants used as supplements; Measurements before supplementary food administration; Cake and sugar syrup administration with supplements; Measurements on well established time intervals. In honeybees supplementary feeding as sugar syrup and cake, were added: fresh and dry nettle infusions, Echinacea infusion, thyme infusion, fresh onion and garlic juices, selenium as microelement, Echinacea and selenium mixture, and also Protofil, which is a medicinal plants extract enriched with minerals and vitamins, used by beekeepers against Nosema and for spring stimulation. During the experiments (2005-2008) were created and observed lots formed out of honeybee colonies after wintering period, artificial swarms and artificial weaken colonies by eliminating a ¾ of the population. All supplements were tested on these three categories of experimental lots. The main followed characters were honeybee interval numbers, brood surface (uncapped brood, capped brood and total brood surface) and honeycombs surface. The thesis is structured in the following parts: introduction, objectives, literature study, personal research, conclusions and bibliography. The general part: literature study, contains 4 chapters (I-IV), and describes the importance of beekeeping and current situation on national and international level, notions about honeybee biology and colony structure, aspects regarding beekeeping and feeding and also nutritive supplements administration. Personal research part is structured in 3 chapters (V-VII), containing biological material and used plants (V), methods used for extracts and infusions composition determinations (VI) and also results of the field testing done on different development honeybee colony stages (VII). 37
