We examined the effect of amphotericin B (AmB) on the following enzymatic markers: aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and on non-enzymatic markers: glucose, triglycerides, and proteins in the haemolymph of a model organism, Apis mellifera. AmB is an antifungal antibiotic. Despite its toxicity, it is used to treat disease conditions. The haemolymph of honey bees is considered as an analogue of human blood, and changes in marker values indicate pathological states, both in humans and honey bees. Three groups of caged bees were fed sugar syrup (the control group). The syrup was supplemented with AmB at concentrations of 0.25 mg/ml (AmB-25) and 0.50 mg/ml (AmB-50). The authors observed that the biochemical markers were age-related in the control group. Decreased values of the enzymatic markers in the AmB-treated groups confirm that AmB has a negative effect on the organism. The higher the dose of the antibiotic, the greater the increase in the concentration of the non-enzymatic markers. Our research shows that honey bees are an important model for studying the effects of AmB.

The study was aimed at investigating whether keeping colonies on small-cell combs (cell width of 4.93 mm), in combination with natural selection resulting from the lack of V. destructor treatment, leads to an intensification of hygienic behaviour. We also sought to determine whether the very transfer of colonies treated against V. destructor (without natural selection) onto small-cell combs causes an intensification of hygienic behaviour. Hygienic behaviour was monitored in both varroatosis-treated and untreated colonies kept on small-cell combs, as well as in two control groups consisting respectively of varroatosis-treated and untreated colonies kept on combs with standard size cells (cell width of 5.56 mm). Regardless of whether they had been treated or not, the colonies kept on the small-cell combs removed dead pupae (needle test) faster than the colonies kept on the standard-cell combs, both treated and untreated. In this way, we demonstrated that hygienic behaviour can be intensified by transferring colonies onto small-cell combs, even without natural survival selection resulting from the lack of treatment against V. destructor. The practical use of this method, however, requires further studies of various bee populations, as they may differ significantly in the intensity of hygienic behaviour and, possibly, in their aptitude for being kept on small-cell combs.

:Effect of mating nucs spacing and subspecies of honey bee (Apis mellifera) on the drifting of queens returning from mating flights. The loss of honeybee queens during mating flights increases the cost of their production. The aim of the study was to examine if the spacing of nucs influences the drifting of queen honey bees which return from mating flights. The study also compared the drifting of Carniolan (A. m. carnica) and Italian (A. m. ligustica) queens. We examined the total of 89 queens which were placed in mating nucs together with about 1000 workers. Some of the mating nucs were arranged in rows spaced 30 centimetres apart, without any landmarks, and other nucs were spaced a few meters apart, next to trees or bushes. Each group of nucs included Carniolan and Italian queens. The results show that significantly more queens failed to return from mating flights to nucs placed in rows without any landmarks (51%) than from those placed next to trees or bushes (7%). The study also showed that there is no significant differences between level of drifting of Carniolan and Italian queens.

The aim of this study was to analyze the information on the taxonomy of bee viruses in order to help the reader to navigate throughout this topic. Classification of bee viruses is a changing system. The best known bee viruses belong to the Dicistroviridae and Iflaviridae (Picornavirales; ssRNA +) families. Taxa from the Baculoviridae, Iridoviridae and Poxviridae families should be also considered as potential honeybee pathogens. English researchers have informed about 18 “important bee viruses”. 21 different apian virus taxa were blamed, among others, for honeybee losses in US apiaries, including 10 virus taxa considered as the most pathogenic. One of the most comprehensive descriptions of the known bee virus taxa has been provided in the materials of the European COLOSS project. Detailed data from all the above sources were shown in this review. We also analyzed the possibilities of the appearance of some honeybee-parasite viruses, as well as other insect viruses and plant viruses in honeybees. A separate table provides information about the additional publications on the most important taxa of the apian viruses. The crucial role of V. destructor infestation for increased risk of viral infections and, therefore, the urgent need of research on apian virology and on ways of increasing of the honeybee immunity/resistance has been indicated.

Honey bees (Apis mellifera) are constantly exposed to contact with many types of pathogens. However, during evolution they developed a number of immune mechanisms. At the individual level, they comprise 1) resistance mechanisms associated with anatomical and physiological barriers of the body, 2) cell-mediated immunity involving hemocytes (including plasmocytes, lamellocytes, and granulocytes), 3a) congenital humoral resistance related to the activity of lysozyme (N-acetylmuramylhydrolase), the prophenylooxidase system (ProPO) and hemagglutinins (lectins), and 3b) induced humoral resistence based on the action of antimicrobial peptides: apidicines, hymenoptecin, and defensins. In addition to the individual resistance of each bee, there is also a defense mechanism activated at the colony level. Shared secretion resistance is connected with the presence of antipathogenic compounds in secreta and in bee products. Social immunity is associated with hygienic and nursing behaviors, as well as with age polyethism in the colony, swarming (and the emergence of rebel workers), and the changing behavior of sick individuals. Many aspects and interactions between different types of resistance and immunity still remain unexplored. However, current research trends revolve around clarifying uncertainties so as to strengthen the natural resistance of bees and fight against pathogens that threaten the insects.

The aim of research was the assessent of the hygienic behaviour of worker bees. The hygienic behaviour was assessed by means of two test types: the traditional needle test and a test proposed by the authors that consisted in measuring the removal rate of cardboard pieces. The experiments were conducted over three seasons and comprised a total number of 60 colonies. It was proved that the cardboard removal test may replace the needle test in the selection process of bees resistant to brood diseases, but primarily in those bees that have a good expression of hygienic behaviour. The best test results are to be expected in tests which last for 24 hours.

Basing on selected literature positions the biology and the methods of control of mites - parasites of honey bee: Acarapis woodi, Varroa jacobsoni and Tropilaelaps clareae, have been concisely presented. T. clareae is known to occur on A. mellifera only in Asia and causes there important losses in apiaries. Also biology of a few mite species which are not parasites but live in bee hives or are pests of apiaries has been briefly presented. The following species belong to this group: Glycyphagus domesticus, Acarus siro, Tyrophagus putrescentiae, Tyropagus longior, Carpoglyphus lactis. Of other mites presented in the paper, representatives of the genera Macrocheles and Neocypholaelaps should be mentioned as well as species associated generally with bumble bees and only accidentally found in bee families or directly on bees.

The aim of this study was to learn the strength of floral fidelity of honeybee colonies and to find what is the relationship between this trait and the amount of collected pollen. The observations were carried out in 2003 and 2004 on 10 honeybee colonies. The pollen was gathered from pollen loads collected using a pollen trap with a 5-mm screen mesh. A scanning electron microscope was used to view pollen grains in order to determine the number of plant species visited by the bees. The mean values of floral fidelity estimated individually for each experimental colony ranged from 40.1 to 75.7% in the first year, and from 45.1 to 67.3% in the second year of the studies. Correlation between floral fidelity and the quantity of collected pollen was observed in 60% of the colonies in the first year and in 70% in the second year. Recurrence of this relationship over the period of two years was found in only 30% of the studied honeybee colonies.
