The strength of honey bee colonies during year depends on wintering and on biologic development of colonies during spring period. To ensure satisfactory colony development in spring period, it is necessary to add stimulative feed. The aim of this study is to determine the effect of different types of spring feed on the honey bee colony strength. Twenty honey bee colonies were selected for this experiment. Colonies were divided into five groups, and each group received different stimulative feed. The first group was fed with sugar syrup, and the second with sugar syrup with added microelements and with vitamin complex. The third group received sugar candy without additives, and the fourth group received sugar candy with addition of microelements and vitamins. The fifth group was fed with honey. The experiment was conducted on the apiary of the Institute for forage crops in Krusevac.

A healthy honey bee stock is critical to the beekeeping industry and the sustainability of the ecosystem. The quality of the supplemental diet influences the development and strength of the colony, especially during the pollen dearth period in the surrounding environment. However, the extent to which pollen substitute protein feeding affects honey bee colony parameters is not fully known. We conducted this study to test the influence of various supplemental diets on foraging effort, pollen load, capped brood area, population density, and honey yield. The treatment groups were supplied with patties of pollen substitute diets, whereas sugar syrup was given to the control group. Our results indicated that honey bees consumed a significantly higher amount of Diet 1 (45 g soybean flour + 15 g Brewer’s yeast + 75 g powdered sugar + 7.5 g skimmed milk + 7.5 g date palm pollen + 200 mL sugar syrup supplement with Vitamin C) followed by others supplemented diets. Further, pollen load, worker-sealed brood area, population strength, and honey yield differed significantly when Diet 1 was consumed instead of other supplemental diets. The proportion of biological parameters was less in the control group as compared to other treatments. This study highlights the potential of supplemental diets to improve the bee’s health and colony development when the pollens availability and diversity are insufficient.

Sublethal Concentrations

AbstractHoney bee colonies were exposed to sublethal concentrations (5 and 20 ppb) of clothianidin in sugar syrup, while control colonies were fed syrup with no pesticide. In addition to standard colony assessments of adult bees and brood, hive weight and internal temperature were monitored on a continuous basis at all sites. Experiments were conducted twice in Arizona, in successive years at the same site, and once in Mississippi, to examine the concomitant effects of weather and landscape. Adult bee masses at the Arizona site were significantly affected by clothianidin concentration. Newly-emerged bee dry weights, measured only at the Arizona site, were significantly lower for colonies fed 5 ppb clothianidin compared to the other groups. CO2 concentration, also only measured at the Arizona site, was higher in colonies fed 20 ppb clothianidin. Neither daily hive weight change nor colony thermoregulation were affected by clothianidin exposure. The Mississippi site had higher rainfall, more diverse land use, and a different temperature regime, and bee colonies there did not show any effects of clothianidin. These results suggest that bee colonies in more stressful environments, such as the Sonoran desert of southern Arizona, are affected more by clothianidin exposure than colonies at sites with higher rainfall and more forage. Clothianidin was also found to be, like imidacloprid, highly stable in honey in the hive environment at least over several months. These results also showed that CO2 concentration within the hive is potentially valuable in measuring the effects of stressors on bee health.

Intensive Search

In the modern world, the problem of honey-bee colonies’ death is acute. An intensive search is underway for environmentally friendly preparations that could stimulate the bees’ resistance to various diseases, as well as have a beneficial effect on the body, thereby contributing to an increase in honey productivity. Preparations based on live probiotics bacteria of Lactobacillus and Bacillus subtilis genus are currently becoming increasingly popular. The use of probiotics in beekeeping allows to destroy pathogenic microflora, strengthen immunity and activate the body’s metabolic processes. The aim of the study was to determine the influence efficiency of probiotic preparations complex ApiVrach, SpasiPchel, Pche-loNormoSil during the period of spring development on the economically useful traits of honey-bee colonies. Studies have found that when probiotics are added to sugar syrup in the spring, the brood growth of bee colonies and their honey productivity are activated. The flight activity of bees when feeding with probiotic preparations increased by 43.6% from the control group. When assessing the dynamics of the bee colony’s strength, it was found that the usage of “ApiVrach” + “PcheloNormoSil” combination allows increasing the amount of sealed brood by 4 times, and the strength of the bee colony - by 1.5 times. Also, this combination of preparations made it possible to obtain the largest amount of total honey yield by 19.2% more than the control group, by 3.0% more than the group that received the ApiVrach + SpasiPchel complex and by 1.1% more than when using ApiVrach.

AbstractThe effects of agricultural pesticide exposure upon honey bee colonies is of increasing interest to beekeepers and researchers, and the impact of neonicotinoid pesticides in particular has come under intense scrutiny. To explore potential colony-level effects of a neonicotinoid pesticide at field-relevant concentrations, honey bee colonies were fed 5- and 20-ppb concentrations of clothianidin in sugar syrup while control colonies were fed unadulterated syrup. Two experiments were conducted in successive years at the same site in southern Arizona, and one in the high rainfall environment of Mississippi. Across all three experiments, adult bee masses were about 21% lower among colonies fed 20-ppb clothianidin than the untreated control group, but no effects of treatment on brood production were observed. Average daily hive weight losses per day in the 5-ppb clothianidin colonies were about 39% lower post-treatment than in the 20-ppb clothianidin colonies, indicating lower consumption and/or better foraging, but the dry weights of newly-emerged adult bees were on average 6–7% lower in the 5-ppb group compared to the other groups, suggesting a nutritional problem in the 5-ppb group. Internal hive CO2 concentration was higher on average in colonies fed 20-ppb clothianidin, which could have resulted from greater CO2 production and/or reduced ventilating activity. Hive temperature average and daily variability were not affected by clothianidin exposure but did differ significantly among trials. Clothianidin was found to be, like imidacloprid, highly stable in honey in the hive environment over several months.

Several negative factors contribute to a decline in the number of insect pollinators. As a novel approach in therapy, we hypothesize that the EM® for bees could potentially have an important therapeutic and immunomodulatory effect on honey bee colonies. The aim of our study was to evaluate its impact on honey bees at the individual and colony level. This is the first appliance of the commercial probiotic mix EM® PROBIOTIC FOR BEES in honey bees as economically important social insects. The sugar syrup with 10% of probiotic was administered by spraying or feeding the honey bee colonies in the field conditions, in order to evaluate the infection levels with spores of Nosema spp. and colonies’ strength. Moreover, in laboratory-controlled conditions, in the hoarding cages, adult workers have been fed with sugar syrup supplemented with 2.5, 5, and 10% of EM® for bees for biochemical and immunological analyses of hemolymph, and with 5 and 10% for measuring the size of hypopharyngeal glands. It was found that following the EM® for bees administration the Nosema spp. spore counts in colonies were significantly reduced, and colonies’ strength was increased. The results at the individual level showed significant positive physiological changes in treated groups of adult bees, revealing at the same time a higher mortality rate when feeding sugar syrup supplemented with the probiotic.

Nutritional Effect

AbstractAlpha-linolenic acid (ALA), which is an n-3 polyunsaturated fatty acid (PUFA), influences honey bee feed intake and longevity. The objective of this study was to research the effect of six dietary ALA levels on the growth and development of Apis mellifera ligustica colonies. In the early spring, a total of 36 honey bee colonies of equal size and queen quality were randomly allocated into 6 groups. The six groups of honey bees were fed a basal diet with supplementation of ALA levels at 0 (group A), 2 (group B), 4 (group C), 6 (group D), 8 (group E), and 10% (group F). In this study, there were significant effects of pollen substitute ALA levels on the feeding amounts of the bee colony, colony population, sealed brood amount, and weight of newly emerged workers (P<0.05). The workers’ midgut Lipase (LPS) activity of group C was significantly lower than that of the other groups (P<0.01). The worker bees in groups B, C, and D had significantly longer lifespans than those in the other groups (P<0.05). However, when the diets had ALA concentrations of more than 6%, the mortality of the honey bees increased (P<0.01). These results indicate that ALA levels of 2 ~ 4% of the pollen substitute were optimal for maintaining the highest reproductive performance and the digestion and absorption of fatty acids in honey bees during the period of spring multiplication. Additionally, ALA levels of 2 ~ 6% of the pollen substitute, improved worker bee longevity.

Abstract. The aim of the present study is to investigate the effect of Baikal EM1 on the productive parameters of the bee colonies (Apis mellifera L.) during spring and autumn feeding and the chemical composition of the worker bee bodies. Two groups of bee colonies were formed (1 experimental group and 1 control group). During the spring feeding the experimental group was fed with Baikal ЕМ1 at a dose of 5 ml/0.500 L added in the sugar syrup (sugar:water 1:1) for 4 consecutive days at the start of the experiment. Each bee colony received 5 L sugar syrup. During the autumn feeding the experimental group received Baikal ЕМ1 at a dose of 20 ml/10 L sugar syrup. Each bee colony received 10 L sugar syrup. The control group received only sugar syrup. The spring and autumn feeding of the group fed with Baikal EM1 significantly increases the strength of the bee colonies and the amount of the sealed worker brood compared to the control group. According to the results obtained for the strength of the bee colonies and the bee brood supplementary feeding with Baikal EM1 is very effective in the autumn feeding. For these two parameters there are significant differences between the experimental and control on 29.08. (p<0.01), 10.09. (p<0.05) and 22.09.2018 (p<0.01). Statistically significant differences were reported for the strength of the bee colonies (p<0.01) and the amount of sealed worker brood (p<0.001) in the experimental group receiving Baikal EM1 before wintering compared to the control group. It can be expected to reveal a tendency for better spring development in the next year. Feeding with Baikal EM1 does not affect the chemical composition of worker bee bodies.

This paper studied the production and management of honey bee in dang district. 35 respondent rearing commercially honey bee of Tulsipur and Ghorahi sub-metropolitan city and Banglachuli rural municipality were selected by using Purposive sampling techniques out of 141 commercial bee growers (Registered AKC, PMAMP). Structure questionnaire where designed to sample opinion of respondents. Data were collected using M-water surveyor mobile Application by using pretesting questionnaire and analyzed using MS-Excel, Statistical Package of Social Science. Results obtained that 72% respondents commercially rearing Apis millifera and 11% rearing Apis cerana. Farmers having 22-117 numbers of hives found maximum (77%). Maximum number of hives rearing found was 500 by commercial bee keepers. Average hive number and Average productivity found were 98 and 31.2kg per hive per year (Apis millifera). 89% respondent were found increasing their enterprise and good source of income was found as the main reason to increase their enterprise whereas 11% respondent were decreasing their enterprise and Shortage of forage was found as the main reason to decrease their enterprise. Hive cleaning practice was adopted by majority of the farmer (40%) to protect the hive from rainy and summer season whereas feeding with sugar syrup was adopted by most of the farmer (80%) during rainy and summer season. Hive covering with jute sacs and straw was found most adopted practice (69%) to protect the bee colonies during winter season. Commercial bee keepers having more number of bee hives and migrate their beehives for foraging in different places outside the valley were found 4 and more times honey harvesting whereas two times harvesting was found by beekeepers rearing Apis cerana. Most of the farmer used to sell honey from farm gate (94%) however the most selling was done to the whole sellers due to lack of storing and processing equipment.

Climate, plant communities, and timing of floral resources differ significantly across Florida, which means that management of European honey bee colonies in Florida differs as well. This 8-page fact sheet written by James D. Ellis, Mary C. Bammer, and William H. Kern and published by Department of Entomology and Nematology outlines a management calendar created for Florida beekeepers. It is specific to region (north, central, and south Florida) and month and includes recommendations for major management considerations like when to treat for parasites or pathogens and when to feed colonies or harvest honey. This management calendar, while not exhaustive, is a valuable reference or starting point for honey bee colony management in Florida. http://edis.ifas.ufl.edu/in848

ABSTRACTIn the last decade, the use of neonicotinoid insecticides increased significantly in the agricultural landscape and meanwhile considered a risk to honey bees. Besides the exposure to pesticides, colonies are treated frequently with various acaricides that beekeepers are forced to use against the parasitic mite Varroa destructor. Here we have analyzed the impact of a chronic exposure to sublethal concentrations of the common neonicotinoid thiacloprid (T) and the widely used acaricide τ-fluvalinate (synthetic pyrethroid, F) - applied alone or in combination - to honey bee colonies under field conditions. The population dynamics of bees and brood were assessed in all colonies according to the Liebefeld method. Four groups (T, F, F+T, control) with 8-9 colonies each were analyzed in two independent replications, each lasting from spring/summer until spring of the consecutive year. In late autumn, all colonies were treated with oxalic acid against Varroosis. We could not find a negative impact of the chronic neonicotinoid exposure on the population dynamics or overwintering success of the colonies, irrespective of whether applied alone or in combination with τ-fluvalinate. This is in contrast to some results obtained from individually treated bees under laboratory conditions and confirms again an effective buffering capacity of the honey bee colony as a superorganism. Yet, the underlying mechanisms for this social resilience remain to be fully understood.
