“…Other treatments, such as acetylsalicylic acid with extract of Artemisia absinthium L. and extracts of Aster scaber and Artemisia dubia, are currently under study (Kim et al, 2016;Michalczyk et al, 2016). Alternative products have been tested under laboratory conditions with some success (Porrini et al, 2010;Bravo et al, 2017), although they are not commercially available.…”

Nosema ceranae is a hot topic in honey bee health as reflected by numerous papers published every year. This review presents an update of the knowledge generated in the last 12 years in the field of N. ceranae research, addressing the routes of transmission, population structure and genetic diversity. This includes description of how the infection modifies the honey bee's metabolism, the immune response and other vital functions. The effects on individual honey bees will have a direct impact on the colony by leading to losses in the adult's population. The absence of clear clinical signs could keep the infection unnoticed by the beekeeper for long periods. The influence of the environmental conditions, beekeeping practices, bee genetics and the interaction with pesticides and other pathogens will have a direct influence on the prognosis of the disease. This review is approached from the point of view of the Mediterranean countries where the professional beekeeping has a high representation and where this pathogen is reported as an important threat.

“…and Aster scaber Thunberg, at non-toxic concentrations, proved to show anti-nosemosis effects [ 28 , 29 ]. In several studies, essential oils such as mint ( Mentha pepper L.), melissa ( Melissa officinalis L.), coriandrum ( Coriander sativum L.), thyme ( Satureja hortensis L.) oils, other phytochemicals such as caffeine, clove oil, gallic acid, kaempferol and p-coumaric acid, and even propolis expanded honeybee longevity and to some extent, reduced nosemosis levels [ 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. Such phytochemicals as clove oil, laurel extract and sulforaphane, moderately decreased Nosema -infection, but at the same time, strongly reduced honeybee lifespan [ 33 , 36 , 37 ].…”

Pollinators, the cornerstones of our terrestrial ecosystem, have been at the very core of our anxiety. This is because we can nowadays observe a dangerous decline in the number of insects. With the numbers of pollinators dramatically declining worldwide, the scientific community has been growing more and more concerned about the future of insects as fundamental elements of most terrestrial ecosystems. Trying to address this issue, we looked for substances that might increase bee resistance. To this end, we checked the effects of plant-based adaptogens on honeybees in laboratory tests and during field studies on 30 honeybee colonies during two seasons. In this study, we have tested extracts obtained from: Eleutherococcus senticosus, Garcinia cambogia, Panax ginseng, Ginkgo biloba, Schisandra chinensis, and Camellia sinensis. The 75% ethanol E. senticosus root extract proved to be the most effective, both as a cure and in the prophylaxis of nosemosis. Therefore, Eleutherococcus senticosus, and its active compounds, eleutherosides, are considered the most powerful adaptogens, in the pool of all extracts that were selected for screening, for supporting immunity and improving resistance of honeybees. The optimum effective concentration of 0.4 mg/mL E. senticosus extract responded to c.a. 5.76, 2.56 and 0.07 µg/mL of eleutheroside B, eleutheroside E and naringenin, respectively. The effect of E. senticosus extracts on honeybees involved a similar adaptogenic response as on other animals, including humans. In this research, we show for the first time such an adaptogenic impact on invertebrates, i.e., the effect on honeybees stressed by nosemosis. We additionally hypothesised that these adaptogenic properties were connected with eleutherosides—secondary metabolites found exclusively in the Eleutherococcus genus and undetected in other studied extracts. As was indicated in this study, eleutherosides are very stable chemically and can be found in extracts in similar amounts even after two years from extraction. Considering the role bees play in nature, we may conclude that demonstrating the adaptogenic properties which plant extracts have in insects is the most significant finding resulting from this research. This knowledge might bring to fruition numerous economic and ecological benefits.

Horminum pyrenaicum L. is a medicinal, aromatic and ornamental plant native to the Pyrenees and Alps. The phytochemical composition is affected by various ecological factors, climatic conditions and cultivating factors, and especially phenological growth stages. Flavonoids, phenolic acids and triterpenic acids were identified and quantified in the above-ground parts of H. pyrenaicum during the phenological stages. The massive flowering was distinguished with the greatest total amounts of phenolic compounds (22232.8 μg/g), and rosmarinic acid was the predominant compound. The amounts of triterpenic compounds were at the lowest during the intense growth stage and significantly increased up to the massive flowering. The prevailing compounds were ursolic acid and betulinic acid, 12092.4 μg/g and 2618.9 μg/g, respectively. The major essential oil compounds were β-phellandrene (56.6%), caryophyllene oxide (5.9%), (Z)-caryophyllene (4.4%), myrcene (4.1%) and thymol (3.6%). Selecting the optimal harvesting time could ensure the herbal raw material rich with preferred bioactive compounds.
