In many areas in Central Europe, rape culture is one of the main nectar flows for bees. The natural spring development of honey bee colonies is too late for the full utilization of nectar plants in May. It is recommended to use spring managements, which increase the amount of brood, reared in March and April, to obtain as many foragers as possible for spring flows. According to many beekeepers, uncapping of combs with winter food is a very good method of accelerating the development of bee colonies in spring. The purpose of this study was to investigate whether the uncapping of winter food affects the amount of brood reared. The research was conducted in April 2007 and 2009 in south-eastern Poland. In total, 54 honey bee colonies were investigated. Winter food was uncapped in half of the colonies, and in the other half no management was used. The comparison of development in both groups was based the measurements of brood areas. It was found that the uncapping of combs with winter food in early spring had no significant effect on the amount of brood reared in honey bee colonies.

: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 study compares honey production in bee colonies with instrumentally inseminated and naturally mated queens. Poland has a special place in the world in terms of the numbers of instrumentally inseminated queens. Our country uses more of them than all other countries taken together. The dense distribution pattern of apiaries in Poland prevents any control over natural mating, while at the same time many bee-keepers who look for valuable breeding material decide to use instrumentally inseminated queens in their honey-making colonies. The cost of purchasing an instrumentally inseminated queen should be compensated by an increased productivity of the colony. The study was aimed at determining whether that was possible. The comparison was carried out at a large professional apiary in the season of 2008. Two comparison groups were created of 12 colonies each. Honey was harvested 3 times during the season. The average production of honey in the group with in-strumentally inseminated queens significantly exceeded average production in that with naturally mated queens.

Injuries of honey bee workers and drones caged in native and foreign colonies. In June and July 2008 worker bees and drones were kept in plastic transport cages in native and foreign colonies. 4,224 honey bees were used in the investigation (1.920 workers and 2,304 drones). After 3 and 7 days of storage the bees' injuries were checked with a stereoscopic microscope. The results were used to determine the percentage of injuries and mortality of the bees. Both worker bees and drones stored in native and foreign colonies were subject to injuries. The injuries were limited mainly to legs and arolium, with occasional injuries to wings and antennae. The highest level of injuries was recorded for workers stored for 7 days in foreign colonies (almost 8%) and the lowest for drones stored for 3 days in native and foreign colonies (1.5%). The highest mortality was recorded for drones stored in native and foreign colonies for 7 days (around 71%), and the lowest for workers stored in native colonies for 3 days (almost 6%). It was observed that the location of cages influenced the number of injured and dead workers. The percentage of injured bees was found to be dependent on the duration of their storage in the colony. The longer the storage time of worker bees and drones, the higher the injury rate. The number of injured bees was also influenced by sex, as males were injured distinctly less often than females. The death rate of drones stored in cages was significantly higher than that of worker bees.

Experiment was performed at Apiculture Division, Warsaw University of Life Sciences – SGGW in 2005/2006 season. The aim of this study was to analyze the quality of mason bee pupae (Osmia rufa L.) originating from annual and biennial slots. Obtained cocoons were classified. Cocoons were divided into groups of healthy cocoons, empty cocoons, broken and infected. It was also examined and identified the presence of parasites praying on the mason bee cocoons. Research shows that in twoyear old slots is more than 10 times less healthy cocoons and three times more damaged cocoons in comparison to the annual sockets. Species diversity of parasites in the biennial nests is wider than in the annuals. In annual material it was found only one parasite belonging to the species Cacoxenus indagator whereas biennial material contained species: Cacoxenus indagator, Giraudiella inclusa, Trichodes apiarius and Sapyga quiquepunctata. Research shows that the mason bee slots should be used once. Repeated use of slots increases the degree of infestation with parasites which reduces reproductive performance.

The research was performed at Apiculture Division of Warsaw University of Life Sciences – SGGW in 2004–2006. Main observations were carried in February and in March 2006. The aim of this study was to present the differences in mason bee (Osmia rufa L.) survival resulting from the nests usage. After opening all the tubes it was found that in annual nest quite healthy cocoons was 1618 (21%) and the loss of 6208 (79%). In the biennial nest profit was only 157 cocoons (2.5%) and the loss of up to 6075 cocoons (97.5%). Taking into account the number of healthy cocoons (profit) as well as representing a loss in both types of nests it can be noted that in the annual nest it could received more than 15 cocoons from the female. However, in the biennial nest, which can be expected more numerous population, it was achieved in one year only 11 cocoons from the female.

The use of electric smoker for the application of Apiwarol is a practical method for Varroa destructor control in honey bee colonies. However, according to some reports this method may decrease the efficacy of the drug. The aim of this study was to compare Varroa control in colonies treated by the electric smoker Wakont and in the traditional method. Twenty colonies were investigated. They were fumigated four times every four days. The electric smoker was used in ten colonies and in another ten colonies the tablets were smoked inside the beehives on the bottom board. Bottom traps were inserted in hives to collect and count dead Varroa. A day after the last fumigation treatment, a sugar roll test was applied to assess the number of mites left on bees. There were no statistically significant differences in the Varroa fall during the treatments and in the number of mites left on bees after the treatments between these two groups. We did not ascertain a decreasing of the effectiveness of Apiwarol after application by using the electric smoker.

The experiment was performed at the Apiculture Division of Warsaw University of Life Sciences in 2009. The aim of this study was to investigate the bees awaking time and to check their survival rate during their waking up with the application of gas mixtures of different concentration of oxygen and nitrogen. In the experiment were examined 2000 worker bees (Apis mellifera L.). All bees were subjected anesthesia with carbon dioxide and awaken by air containing various proportions of oxygen and nitrogen. 241 bees were divided into 5 groups. The control group was awaken from anesthesia with the carbon dioxide in the atmospheric air. Experimental group were awaken in the air containing 50% of O2 and 50% of N2, 40% of O2 and 60% of N2, 30% of O2 and 70% of N2, 15% of O2 and 85% of N2. There was no repeatability of results between all examined groups in the first abdominal movements, individual walking bees and in all the bees awaking. Survival rate of groups of bees awaken in a mixture of 40% oxygen and 60% nitrogen was significantly higher in comparison to other groups. This experience was a prelude to further research on queen bees in order to accelerate the awakening from carbon dioxide anesthesia during insemination, and accelerate lying eggs.

The function of vestibulum (the outermost empty brood cell, without provisioning mass and larvae) has not been precisely determined so far. It is most probably a behavioral relic, which currently has no adaptive value. However, red mason bees often build vestibulum. In this study, we examined the nest tubes of red mason bees in three sites (Kłoda, Kanie and Warsaw) in Mazovian Province and in one site (Sąpłaty) in Warmian-Masurian Province. About 70% of the nest tubes in Kłoda, Kanie and Warsaw had vestibulum, whereas only 29% of the tubes in Sąpłaty had vestibulum. It can be assumed that the vestibulum protects the brood against unstable atmospheric conditions, and the proximity of the lake Sąpłaty reduced the temperature amplitude. It was found, however, that the vestibulum did not protect the brood cell against nest parasitoides and cleptoparasites. More cells were infested by parasites and kleptoparasites in tubes with vestibulum.

The diversity and abundance of bumblebees (Bombus Latr.) in eight parks of Warsaw city and the impact of park size (range from 1.9 to 73 ha) as well as other selected characteristics (the percentage of the area covered by tree and the quality of park surroundings) on the bumblebee community were evaluated. In each park, bumblebees were observed along designated paths for 30 minutes. In total, 12 species of bumblebees were recorded, of which four belonged to cuckoo bumblebees (Psithyrus subgenus). We found: B. terrestris (L.), B. lapidarius, (L.), B. pascuorum (Scop.), B. hortorum (L.), B. semenoviellus (Skorikov), B. hypnorum (L.), B. ruderarius (Müller), B. pratorum (L.) and four cuckoo bumblebee species: B. (Ps.) bohemicus (Seidl.), B. (Ps.) campestris (Pz.), B. (Ps.) rupestris (F.), B. (Ps.) vestalis (Fourc.). The size of parks, percentage of area covered by trees, and characteristics of the areas surrounding the parks were found to be not significant for the diversity and abundance of bumblebees in urban parks. However, our results indicate the importance of the semi-natural areas within the parks for the species diversity.

Antibacterial properties of metal nanoparticles are well documented and known, but its potential use in agriculture as an anti pest agents – not. Possible negative or positive reactions with popular integrated pest management (IPM) methods need to be checked and verifi ed. The effect of copper nanoparticles on the mortality of entomopathogenic nematodes (EPNs) Steinernema feltiae from Owinema biopreparation was tested. This biopreparation is being used against serious agricultural pests. It was found that mortality of nematodes depends on nano- -Cu concentrations and on the length of contact of Steinernema larvae with nano-Cu solution. In this study the effect of different concentrations of nanoparticles on pathogenic properties of entomopathogenic nematodes – mortality of pest beetle Alphitobius diaperinus (Panzer, 1797) infected by EPNs and extensiveness of infection, was also studied. It showed that the high concentrations of Cu may decrease abilities of EPNs to enter, grow and proliferate inside the host body.

Nests of red mason bees (Osmia bicornis L.) are inhabited by characteristic accompanying fauna, which to a varying extent restricts the development of the bee population. The aim of this research was to conduct a comparative analysis of nest material from four sites. At three sites artificial nests of common reed and bee cocoons were placed for the first time (M1 – Kłoda, Masovian Voivodeship, M2 – Sąpłaty, Warmian-Masurian Voivodeship, M3 – Kanie, Masovian Voivodeship). At the fourth one (M4 – an experimental apiary of the Warsaw University of Life Sciences) mason bee nests and cocoons had been placed every year for 10 years. The number of species accompanying mason bees, the number of dead larvae, fully formed cocoons and parasites/ cleptoparasites at the newly populated sites was determined and compared with the perennial mason bee nesting site. In nests M1, M2 and M3, 5-7 species of accompanying fauna were found, whereasin M4 as many as 14 species were identified. The parasites that restricted the bee population most significantly at all sites were Cacoxenus indagator, Monodontomerus obscurus and Chaetodactylus osmiae. Not all of these species caused most damage at the perennial bee nesting site. C. indagator occupied most cellsin M4, whereas C. osmiae in M3. M. obscurus parasitized the same number of cells in M3 and M4. Other species identified mainly in M4 were Tribolium castaneum, Dermesteslardarius, Ptinusfur,Trichodes apiarius,Auplopus carbonarius, Chrysisignita,Anthrax anthrax, Graphopsocus cruciatus, Lepsima saccharina, Fornicula auricularia, Bombus terrestris.
