“…3, 4 and 5). Masry et al [50] reported a similar result when the surface of the sealed worker brood area was increased after the treatment of honey bee colonies with Jatropha curcas oil. Similarly, Stevanovic et al [51] presented the benefi cial effect of a medicinal mushroom Agaricus brasiliensis extract (sugar syrup or candy) on brood rearing improvement and adult population growth in comparison to untreated bee colonies.…”

Winter is the season that poses the greatest challenges for honey bee colonies. Therefore, the main approach in beekeeping practice is aimed mainly at providing sufficient quality food supplies for bee colonies in early autumn. We conducted the present study to test the influence of the natural plant extract IMМUNOSTART HERB on population strength, stored pollen area, capped worker brood area, and honey yield. The experimental groups were supplied with IMМUNOSTART HERB 4 times at 7-day intervals, whereas sugar syrup was given to the control groups. The obtained results showed that the applied supplemental diet affected all investigated biological parameters, with the most noticeable effect after the second application. In all measurements, the honey bee colony parameters in the treated groups showed higher values in comparison to the control groups. These results highlight the potential of herbal supplements to effectively improve bee colonies’ development during the period of scarce bee forage, as well as to provide suitable conditions for successful overwintering.

“…De igual manera, el uso de aceites esenciales como el eucalipto (Eucalyptus spp. ), el neem (Azadirachta indica) y el pomelo (Citrus maxima) reportan toxicidades superiores al 70% sobre este ácaro (Dimetry et al, 2005;Elzen et al, 2000;Melathopoulos et al, 2000). Por otra parte, Ariana et al (2002), describieron un efecto tóxico el cual oscila entre el 45 y 97% mediante el uso de aceites esenciales de Saturea hortensis L., Zataria multifera Boiss, Mentha spicata L., Rosemarinus officinalis L., Origanum vulgare L., Lavandula officinalis L. y Anethum graveolens L en contra V. destructor.…”

Background: The honeybee (Apis mellifera L.) represents one of the most important species in the maintenance of ecosystems, since it contributes to crop pollination, which improves crop yields and the reproduction of other plants. However, some factors such as climate change, africanization and various pathological processes, including the presence of the Varroa destructor mite, have led to a decline in A. mellifera populations. Objective: To collect scientific information on the plants used for mite control, as well as the organic derivatives and secondary compounds with bioacaricidal potential used for such control. Main findings: Due to the fact that infestations of this mite have become a major problem, numerous control methods have been developed and tested, mainly based on synthetic acaricides; however, these have generated disadvantages such as the development of resistance and contamination of products such as honey and pollen. Implications: Therefore, it is necessary to implement an organic, environmentally friendly control method that reduces mite populations without developing resistance, and that does not generate contamination of hive sub-products. Conclusions: In general, the most common types of extracts tested were essential oils and hydroalcoholic extracts, which reported mortality ranging from 26.4 to 99.5% on V. destructor. Likewise, some species of plants endemic to Matorral Espinoso Tamaulipeco (MET) have been tested against other arthropods and that could be an important source of components that act as acaricides; however, it is necessary to identify and analyze the secondary compounds, as well as the molecules and their activity on V. destructor.

“…Therefore, there is an urgent need to find eco-friendly strategies that are both affordable and safe for humans and honey bees to control Varroa mites. Numerous studies have been conducted on natural remedies, such as plant extracts and essential oils, against V. destructor in honey bee colonies [ 354 , 355 , 356 ]. The efficacy of certain plant-based essential oils, such as eucalyptus, thyme, neem, sage, and grapefruit, against Varroa mites has been reported in many studies.…”

Honey bees (Apis mellifera) are agriculturally important pollinators. Over the past decades, significant losses of wild and domestic bees have been reported in many parts of the world. Several biotic and abiotic factors, such as change in land use over time, intensive land management, use of pesticides, climate change, beekeeper’s management practices, lack of forage (nectar and pollen), and infection by parasites and pathogens, negatively affect the honey bee’s well-being and survival. The gut microbiota is important for honey bee growth and development, immune function, protection against pathogen invasion; moreover, a well-balanced microbiota is fundamental to support honey bee health and vigor. In fact, the structure of the bee’s intestinal bacterial community can become an indicator of the honey bee’s health status. Lactic acid bacteria are normal inhabitants of the gastrointestinal tract of many insects, and their presence in the honey bee intestinal tract has been consistently reported in the literature. In the first section of this review, recent scientific advances in the use of LABs as probiotic supplements in the diet of honey bees are summarized and discussed. The second section discusses some of the mechanisms by which LABs carry out their antimicrobial activity against pathogens. Afterward, individual paragraphs are dedicated to Chalkbrood, American foulbrood, European foulbrood, Nosemosis, and Varroosis as well as to the potentiality of LABs for their biological control.
