Honey bees (Apis mellifera L.) are the most effective pollinators for different crops and wild flowering plants, thus maintaining numerous ecosystems in the world. However, honey bee colonies often suffer from stress or even death due to various pests and diseases. Among the latter, nosemosis is considered to be one of the most common diseases, causing serious damage to beekeeping every year. Here, we present, for the first time, the effects from the application of the herbal supplements NOZEMAT HERB® (NH) and NOZEMAT HERB PLUS® (NHP) for treating N. ceranae infection and positively influencing the general development of honey bee colonies. To achieve this, in autumn 2019, 45 colonies were selected based on the presence of N. ceranae infections. The treatment was carried out for 11 months (August 2019–June 2020). All colonies were sampled pre- and post-treatment for the presence of N. ceranae by means of light microscopy and PCR analysis. The honey bee colonies’ performance and health were evaluated pre- and post-treatment. The obtained results have shown that both supplements have exhibited statistically significant biological activity against N. ceranae in infected apiaries. Considerable enhancement in the strength of honey bee colonies and the amount of sealed workers was observed just one month after the application of NH and NHP. Although the mechanisms of action of NH and NHP against N. ceranae infection are yet to be completely elucidated, our results suggest a new holistic approach as an alternative therapy to control nosemosis and to improve honey bee colonies’ performance and health.

Honey bees (Apis mellifera L.) are crucial pollinators for many crops and natural ecosystems. However, honey bee colonies have been experiencing heavy overwinter mortality in almost all parts of the world. In the present study we have investigatеd, for the first time, the effects from the application of the herbal supplements NOZEMAT HERB® (NH) and NOZEMAT HERB PLUS® (NHP) on overwintering honey bee colony survival and on total protein and lysozyme content. To achieve this, in early autumn 2019, 45 colonies were selected and treated with these herbal supplements. The total protein and lysozyme content were evaluated after administration of NH and NHP twice the following year (June and September 2020). The obtained results have shown that both supplements have a positive effect on overwintering colony survival. Considerable enhancement in longevity of “winter bees” has been observed after the application of NHP, possibly due to the increased functionality of the immune system and antioxidant detoxification capacity. Although the mechanisms of action of NH and NHP are yet to be completely elucidated, our results suggest a new holistic approach on overwintering honey bee colony survival and welfare.

The predominance of dietary viruses in bat guano samples had been described recently, suggesting a new opportunity to survey the prevalence and to detect new viruses of arthropods or even plant-infecting viruses circulating locally in the ecosystem. Here we describe the diversity of viruses belonging to the order Picornavirales in Hungarian insectivorous bat guano samples. The metagenomic analysis conducted on our samples has revealed the significant predominance of aphid lethal paralysis virus (ALPV) and Big Sioux River virus (BSRV) in Hungary for the first time. Phylogenetic analysis was used to clarify the relationship to previously identified ALPV strains infecting honey bees, showing that our strain possesses a close genetic relationship with the strains that have already been described as pathogenic to honey bees. Furthermore, studies have previously confirmed the ability of these viruses to replicate in adult honey bees; however, no signs related to these viruses have been revealed yet. With the identification of two recently described possibly honey bee infecting viruses for the first time in Hungary, our results might have importance for the health conditions of Hungarian honey bee colonies in the future.

State of mutual or reciprocal relationship between traits is determined by the correlation coefficients. Correlation of morphological and production traits was determined in two generations of honey bee colonies. In the first generation, mother queen bees were studied, and in the second generation, their offspring. The study of one generation lasted two years. Morphological traits were determined in the beginning of the study and production traits were determined in the spring and autumn inspections of every year. In the first generation, the positive and mostly high correlation between morphological traits, and honey yield and hygienic behavior was determined. Correlation of morphological traits, colony strength and food supplies per colony ranged from highly positive to slightly negative values. It was found that there was a high correlation between some production traits (colony strength in the spring and autumn inspections and honey yield per colony). In the analysis of offspring (second generation), most traits that were positively correlated in mother generation now, also, showed a similar relationship. The only difference, in contrast to mother generation, was that, for most traits, the intensity of interaction increased.

AbstractVarroa mite,Varroa destructor, is the most destructive factor to western honey bee colonies worldwide. In 1904, Varroa was firstly recorded on honey bees, at the beginning it was hypothesized that Varroa is one species but recently this hypothesis has been considered to be incorrect. In 1983, Varroa mite was recorded in Egypt for first time. So far, a single study was done in Egypt to confirm Varroa species to beV. destructorand notVarroa jacobsonias it was previously thought. Still the exact haplotype of Varroa in Egypt is unknown. This study is a step towards the identification of Varroa in Egypt. Here, morphological investigations were performed on Varroa specimens belong to northwest Egypt (El-Behera governorate). Three characteristics only showed significant differences among districts, namely body width, genital shield width, and genital shield length/genital shield width (ratio II), while the rest of characteristics did not present any significant differences. The correlations among the characteristics were very weak, except body length which correlated significantly (P<0.05) with body width and genital shield width by 0.52 and 0.42, in respect. The study presented additional confirmation thatV. destructoris the current species infesting honey bee colonies in Egypt. Also, Varroa haplotype was identified to be the Korean one. A list of some morphological traits of Varroa mite was provided to enable further comparisons. A morphometry map for Varroa mites was also done using a geographical information system (GIS) to correlate between geographical locations and morphological characteristics. The morphometry map clearly classified studied districts, according to measured characteristics, into three classes as low, moderate and high. This study has a significant importance towards the fully understanding of Varroa populations in Egypt.

AbstractHygienic behaviour is a social immune response in honey bees shown to help provide resistance to honey bee pests and diseases. A survey of hygienic behaviour and brood diseases was conducted on 649 colonies in eastern Australia to initiate a selective breeding program targeting disease resistance and provide a level of resistance to Varroa (Varroa destructor Anderson and Trueman and V. jacobsoni Oudemans) mites should they become established in Australia. The test population showed a remarkably high baseline level of hygienic behaviour with 17% of colonies meeting or exceeding breeding selection thresholds. Colonies belonging to a breeding program were 5.8 times more likely to be highly hygienic and colonies headed by queens raised from hygienic queen mothers were 2.2 times more likely. Nectar availability (nectar yielding flowering plants within honey bee forage range) influenced hygienic behaviour expression but was not a significant predictor of level of hygienic behaviour. Surprisingly, hygienic behaviour was not a significant predictor of the presence of infection of the honey bee brood disease chalkbrood (Ascosphaera apis) and was not influential in predicting severity of chalkbrood the infection in surveyed honey bee colonies. This study, along with reports from commercial beekeepers that chalkbrood infection is on the rise, warrants a deeper exploration of the host-pathogen relationship between Apis mellifera and Ascosphaera apis in Australia.

Worldwide, the ectoparasitic mite varroa (Varroa destructor Anderson & Trueman) is potentially the main threatening parasite for Apis mellifera L. To find an alternative therapy for varroa and to limit the chemical residues in bee products, 27 bee colonies with their brood, were treated at 42°C for 12 to 480 minutes. All experimental colonies had 5-8 frames of brood and 10 frames of population (approximately 10.000 bees each colony). During the treatment the final temperature inside the hive varied from 42.3°C to 46.5°C. The effectiveness of hyperthermia to control the varroa population, depends on the duration of the therapy. When the time treatment was extended from 12 to 480 minutes, the falling mites ranged from 29.8% to 79.8%. A small number (4.7%) of dead mites was found in sealed brood after a 60-minute treatment, which gradually increased along with the treatment duration reaching 100% after 480 minutes. The use of the device irritated the bees but did not cause losses of honeybees, or excessive aggravation. Dead larvae inside sealed brood were observed when hyperthermia was applied for more than 120 minutes and increased along with the duration of heating. To our knowledge, in the presence of brood and adult bees, the hyperthermia method is used for the first time as alternative solution to limit the excessive use of chemical substances under field conditions. This method is proved to be most suitable for beekeepers with small amount of colonies.

Aethina tumida (Coleoptera: Nitidulidae), commonly known as the Small Hive Beetle (SHB), is becoming a significant pest in the beekeeping industry outside of its natural distribution range. In Mexico, recent reports indicate that the SHB is distributed throughout the Yucatan peninsula. The invasion of honey bee colonies by SHB it is mainly chemically mediated by volatiles produced by the yeast Kodamaea ohmeri which is regarded as a secondary symbiont of the SHB. It was analyzed the presence of this yeast in honey bee colonies of Yucatan based on the premise that symbionts are often conjointly distributed with their hosts, therefore the presence of K. ohmeri in hives will be closely associated with the presence of SHB. In managed Africanized honey bee (AHB) colonies, yeasts associated with adult beetles were isolated and identified and the results show that the SHB together with their associated yeast, K. ohmeri, have invaded AHB colonies in Yucatan. It was also reported the presence of yeasts other than K. ohmeri associated with SHB that for the first time are recorded in a geographical region where they had not been recorded before.

European foulbrood is a bacterial disease that affects Western honey bee larvae. It is a concern to beekeepers everywhere, though it is less serious than American foulbrood because it does not form spores, which means that it can be treated. This 7-page fact sheet written by Catherine M. Mueller, Cameron J. Jack, Ashley N. Mortensen, and Jamie Ellis and published by the UF/IFAS Entomology and Nematology Department describes the disease and explains how to identify it to help beekeepers manage their colonies effectively and prevent the spread of both American and European foulbrood.https://edis.ifas.ufl.edu/in1272
