Insects hold enormous potential to address food and nutritional security issues. The honey bee is a key insect, given its importance for pollination, as well as its products which can be directly consumed, like honey, pollen and brood. Research on edible insects is an emerging field that draws upon methods and techniques from related fields of research. In this paper, we provide recommendations and research protocols centered on production of worker and drone brood for human consumption, on brood harvesting, including hygienic considerations, on nutritional aspects of brood, on sensory analyses of brood and brood products and on the gastronomic applications of honey bee brood; all of which will help elucidate the edible potential of honey bee brood now, and in the future.

SummaryA variety of methods are used in honey bee research and differ depending on the level at which the research is conducted. On an individual level, the handling of individual honey bees, including the queen, larvae and pupae are required. There are different methods for the immobilising, killing and storing as well as determining individual weight of bees. The precise timing of developmental stages is also an important aspect of sampling individuals for experiments. In order to investigate and manipulate functional processes in honey bees, e.g. memory formation and retrieval and gene expression, microinjection is often used. A method that is used by both researchers and beekeepers is the marking of queens that serves not only to help to locate her during her life, but also enables the dating of queens. Creating multiple queen colonies allows the beekeeper to maintain spare queens, increase brood production or ask questions related to reproduction. On colony level, very useful techniques are the measurement of intra hive mortality using dead bee traps, weighing of full hives, collecting pollen and nectar, and digital monitoring of brood development via location recognition. At the population level, estimation of population density is essential to evaluate the health status and using beelines help to locate wild colonies. These methods, described in this paper, are especially valuable when investigating the effects of pesticide applications, environmental pollution and diseases on colony survival.
