“…Pollination is necessary for the plants to reproduce. The death of a bee colony affects the reproduction of plants, which is necessary for the maintenance of the ecosystem (Flores et al, 2021). Today, the topical issue is the change in the use of varroasis control products, as Varroa mite in the world have become accustomed to synthetic pesticides, and bee colonies are weakening due to the increasing use of chemicals in agriculture (Kasiotis et al, 2021).…”

The aim of this study was to review research findings and information about chemical composition and application of bee drone brood homogenate for food purposes. As the world’s population grows, global warming and the impact of meat production on the ecosystem are increasingly being discussed. Various non-traditional sources of protein, such as insects and larvae, could replace traditional sources of meat protein in the future. Drone brood homogenate is obtained from honey bee drone larvae and is considered to be a very high value by-product of beekeeping. Scientific studies prove the prophylactic properties of drone brood homogenate to improve fertility and strengthen immunity against viral diseases. This product is rich in nutrients, amino acids, vitamins, minerals and hormones but a certain harvesting and processing technology is required to ensure that the product has a sufficient shelf life and an attractive appearance.

Diet is an important factor in the proper development of the individual and the entire colony. A pollen diet affects honey bees in a number of ways. It can stimulate the number and type of hemocytes, the total number of proteins, carbohydrates and lipids, affect the histology of the middle intestine, and ensure the correct ontogenesis of the larvae. Moreover, selected single-flower diets can stimulate the development of the pharyngeal glands that produce royal jelly, thus conditioning the development of secretory immunity. Selected single-species pollen may also increase the phenol oxidase concentration, which contributes to the humoral response. A honey bee diet based on multi-flower pollen is more desirable than a mono-flower diet, but must be properly balanced.

“…Varroa control is known to have a tremendous influence on colony losses (Flores et al, 2021;Francis et al, 2013;Noël et al, 2020;van Dooremalen et al, 2012). For Varroa control (2015-2016, only four veterinary medicinal products were authorized in Belgium to treat Varroa: three based on thymol extract to which Varroa have shown resistance for several years (Bonafos et al, 2011) (Thymovar 15 g bee-hive strip, Apiguard 12,5 g gel, and Apilife Var 8 g bee-hive strip (FASFC, 2015)), and one based on flumethrin (PolyVar Yellow 275 mg bee-hive strip) comparable to the fluvalinate molecule, the active ingredient in Apistan (10,3% w/w bee-hive strip), abandoned a few years ago due to Varroa resistance (Elzen et al, 2000;Rodríguez-Dehaibes et al, 2005) but still authorized in other EU countries so applicable by cascade 2 in Belgium.…”
