“…So, providing colonies with protein source all over the year, especially during dearth periods of pollen is a critical matter. Recently, several studies have given more attention to formulate supplementary diets or substitutes to compensate the lack of the natural protein source (pollen) (Zheng et al, 2014;Amro et al, 2016;Negri et al, 2017;Gamal Eldin et al, 2018;Gregorc et al, 2019;Younis, 2019). Moreover, different pollen types from different plant origin differently effects on the physiological conditions of worker honey bee (Amro et al, 2015).…”

“…Some pollen substitutes were tested for feeding honey bee workers by Amro et al (2016) andGamal Eldin et al (2018). They have considered the consumption of pollen substitute by newly emerged bee workers, development of HPG, longevity of bee workers, and weight of rectal content as important criteria for estimating the suitability of diets for bee workers.…”

Nutritional value of four proteinaceous diets and their physiological effects on honey bee workers were evaluated under laboratory conditions. The tested diets were as follows: diet 1 – date (Phoenix dactylifera L.) syrup, skimmed milk powder and dried brewer's yeast, diet 2 – Fenugreek (Trigonella foenum-graecum L.), Turmeric (Curcuma longa L.) powders and dried brewer's yeast, diet 3 – chickpea (Cicer arietinum L.) flour, wheat germ and dried brewer's yeast and diet 4 - soybean meal, skimmed milk powder and dried brewer's yeast, beside a control group (bee bread). Caged Carniolan honey bee workers were used in the experiments. The consumption rate, workers longevity, development degree of hypopharyngeal glands (HPG), and weight of rectal contents were determined. The greatest consumption rate was recorded for the control group while the lowest one was recorded for diet 4. Feeding bees on diet 3 gave the longest longevity (LT50= 27.0 days) among the tested diets and as a second rank after bees in the control group (LT50 = 29.0 days) while diet 4 showed the lowest longevity (LT50 =20.5 days). The highest HPG development degree (3.78) was recorded for 9 days old bees in the control group, followed by diet 3 (3.24) while the lowest degree (2.14) was to diet 4. The weight of rectal contents of honey bee workers was 13.43, 16.03 and 16.12 mg/bee/3 days for diet 3, diet 1 and diet 2, respectively, suggesting the suitability of these diets to bees. In light of this study, diet 3 and 2 have the best physiological effects for bees with good nutritional values.

“…The nectar substitutes like royal jelly, sugar, honey, glucose, and fructose alone or mixed were used in combination with different types and forms of yeasts and drugs (Fumagillin-an antimicrobial) to feed the bees Kaftanogluet al 2011;Stevanovic et al 2018 Nectar substitutes were also tried in a combination of vitamins, proteins, minerals, and amino acids. Among the mentioned 10 combinations in table 16, along with honey and different sugar forms, different types of vitamins (vitamin A, E, B1, B2, B6, B12, C, D3, E, K1, K3, and multivitamins), proteins (Casein, corn gluten, and whey protein concentrates), amino acids (Pantothenic acid, Nicotinamide, Folic acid, Biotin, K2HPO4) and minerals were tested as an alternate artificial food for honey bees (Gençer et al 2000;El-Sherif 2002;Mahfouz 2016;Gamal Eldin et al 2018).…”

Artificial nutrition in apiculture is a long-term subject of discussion and investigation. The maintenance and boosting of bee colonies in apiculture depends on synthetic food around the globe to overcome the suppressing factors, including dearth periods. The information on types of food components and their combinations used is haphazard and hardly helpful in determining the advancements in the artificial feeding of bees. This study aimed to extract the available information on artificial feeding on honeybees and arrange it most scientifically. The information in the form of research or review articles available on every platform, viz., soft portals, printed journals, books and scientific proceedings, were collected and analyzed to produce a comprehensive and informative review article on the artificial nutrients in apiculture. Compilation of the available information revealed that artificial feeding of bees depends on food components and their combinations. Based on this, it can be suggested that nectar and pollen are basic foods of honey bees, and based on this, the food components were further categorized as nectar supplements and pollen supplements. These supplements were fed to bees as natural nutrients and food components. The natural nutrients include proteins, carbohydrates, vitamins, yeasts, antibiotics, amino acids, enzymes, antioxidants, etc. Meanwhile, under natural food components, cereal grains, pulses, beans, fruits, vegetables, medicinal plants, spices, condiments, and some non-traditional/ miscellaneous kinds of stuff have been included in the bee diets. On the other hand, many diet categories have been prepared using the abovementioned nutrients and food components in various forms and proportions. In general, the pollen and nectar, the main food of bees, have been supplemented under different diet combinations. These diet combinations used pollen and nectar substitutes or combined with other nutrition, drugs, antibiotics, etc. The present investigation provides an updated overview of the food categories and their combinations used in the artificial feeding of bees to date. These findings can help explore new food items and their effective diet combinations.

“…Otherwise, feeding has a good role in improving honey bee survival, immunity, and tolerance to harsh conditions as well as colony development (Babendreier et al, 2004;DeGrandi-Hoffman et al, 2016;Glavinic et al, 2017). Therefore, beekeepers supply their colonies with alternatives to natural feeding including sugar feeding (Abou-Shaara 2017a), pollen alternatives (De Jong et al, 2009;Saffari et al, 2010;Aly et al, 2014;Zaghloul et al, 2017;Gamal Eldin et al, 2018) under the shortage of natural resources availability. The period from autumn to early spring is considered the most challenging time for bee colonies due to the absence of natural food resources, harsh environmental conditions, and the prevalence of bee diseases.…”

From late autumn until the end of winter conditions, bees are exposed to many stress factors including low air temperature and several pathogens. This study aimed to estimate the effects of three commercial materials (acetylsalicylic acid, Echinacea purpurea extract, and vitamin (C) mixed with sugar feeding on some parameters related to stress tolerance using laboratory and field tests. The laboratory tests supported the potential role of vitamin C and Echinacea purpurea extract to enhance the tolerance ability of bees to low temperatures. The most promising results for the recovery time of bees after exposure to low temperatures, survival rates after narcosis, and hemocyte count were recorded with these two materials. After winter the strength of bee colonies fed on sugar feeding mixed with vitamin C and Echinacea purpurea extract were approximately equal to the strength before winter. However, the contrary was obtained with acetylsalicylic acid and the control group. Thus, using vitamin C or Echinacea purpurea extract as safe additives can boost the survival of bee colonies during the winter period.
