The development of a simple, durable, lightweight and disposable beehive for high-density (and netted) orchards and crops distant from beekeeping areas provides a useful product and a further diversification for beekeepers involved in professional pollination services. The total weight of a fully developed Beetube ranged from 2.23 to 3.64 kg, contained about 9101 bees, 3038 cm2 of comb, and had a morning and afternoon flight activity of 19-43 and 11-34 honey bees per minute, respectively.

Specific Regulation

Faced with adverse conditions, such as winter in temperate regions or hot and dry conditions in tropical regions, many insect species enter a state of diapause, a period of dormancy associated with a reduction or arrest of physical activity, development, and reproduction. Changes in common physiological pathways underlie diapause phenotypes in different insect species. However, most transcriptomic studies of diapause have not simultaneously evaluated and compared expression patterns in different tissues. Honey bees (Apis mellifera) represent a unique model system to study the mechanisms underpinning diapause. In winter, honey bees exhibit a classic diapause phenotype, with reduced metabolic activity, increased physiological nutritional resources, and altered hormonal profiles. However, winter bees actively heat their colony by vibrating their wing muscles; thus, this tissue is not quiescent. Here, we evaluated the transcriptional profiles of flight muscle tissue and fat body tissue (involved in nutrient storage, metabolism and immune function) of winter bees. We also evaluated two behavioral phenotypes of summer bees: nurses, which exhibit high nutritional stores and low flight activity, and foragers, which exhibit low nutritional stores and high flight activity. We found winter bees and nurses have similar fat body transcriptional profiles compared to foragers, whereas winter bees and foragers have similar flight muscle transcriptional profiles compared to nurses. Additionally, differentially expressed genes were enriched in diapause-related GO terms. Thus, honey bees exhibit tissue-specific transcriptional profiles associated with diapause, laying the groundwork for future studies evaluating the mechanisms, evolution, and consequences of this tissue-specific regulation.
