Various honey bees, especially subspecies , occur in Africa and are distribute across the continent. The genetic relationships and identical genetic characteristics between honey bee subspecies in Africa (African bee subspecies) have not been widely investigated using sequence analysis. On the other hand, bioinformatics are developed rapidly and have diverse applications. It is anticipated that bioinformatics can show the genetic relationships and similarities among subspecies. These points have high importance, especially subspecies with identical genetic characteristics can be infected with the same group of pathogens, which have implications on honey bee health. In this study, the mitochondrial DNA sequences of four African subspecies and Africanized bees were subjected to the analyses of base composition, phylogeny, shared gene clusters, enzymatic digestion, and open reading frames. High identical base composition was detected in the studied subspecies, and high identical results from all tests were found between and followed by and . The least genetic relationships were found between and the other subspecies. This study presents insights into the genetic aspects of African bee subspecies and highlights similarity and dissimilarity aspects. Also, Africanized honey bees derived from showed high genetic similarities to other African bees, especially . Additionally, specific primers to identify these subspecies were designed and tested.

Honeybees, Apis mellifera, have experienced the full impacts of globalisation, including the recent invasion by the parasitic mite Varroa destructor, now one of the main causes of colony losses worldwide. The strong selection pressure it exerts has led some colonies to develop defence strategies conferring some degree of resistance to the parasite. Assuming these traits are partly heritable, selective breeding of naturally resistant bees could be a sustainable strategy for fighting infestations.

The honey bee (), a subspecies of , is endemic in China and possesses a valuable ecological niche. Understanding the ways to protect this honey bee's populations is crucial, but this topic has been understudied. For the efficient utilization of beekeeping and pollination, there is a need to explore its biology and management practices.

Pesticides may have serious negative impacts on bee populations. The pesticide exposure of bees could depend on the surrounding landscapes in which they forage. In this study, we assess pesticide exposure across various land-use categories, while targeting the Japanese honey bee, Apis cerana japonica, a native subspecies of the eastern honey bee.

The conservation of the genetic integrity of Apis mellifera subspecies has emerged as an important objective. In 2019, the Emilia-Romagna region became the first Italian regional authority to issue a law specifically addressing the protection of the native Apis mellifera ligustica subspecies. In this study we analysed a highly informative portion of the mitochondrial DNA (mtDNA), widely used for assessing genetic diversity of honey bee populations.
