Genetic diversity and population structure of the Saharan honey bee Apis mellifera sahariensis from southeastern Morocco: introgression assessment and implications for conservation

ArticlesBy Abdessamad AGLAGANE 5. June 2023

Abstract – This study assessed the conservation status of the Saharan honey bee (Apis mellifera sahariensis) from southeastern Morocco using 12 microsatellite loci to examine genetic diversity and hybridization with other subspecies. Samples from 148 colonies were clustered into seven populations representing the expected distribution of A. m. intermissa and A. m. sahariensis, and reference…

New resource for Varroa tolerant bees

ArticlesBy NormanCarreck 25. April 2023

Here is a new website put together by Stephen Martin of Salford University, UK, with the help of various beekeepers providing resources for those exploring the possibility of using varroa tolerant bees: https://www.varroaresistant.uk/

Synergistic antioxidant activity of honey bee products and their mixtures

ArticlesBy AhmedKamel 13. April 2023

The goal of this study was to assess the impact of binary combination antioxidant synergistic effects of honeybee products (citrus honey, clover honey, sugar feeding honey, bee pollen, bee bread, bee wax, old wax comb, Egyptian propolis, Chinese propolis, royal jelly, Drone brood homogenate, worker brood homogenate, queen brood homogenate, bee venom) and The present…

Exposure of Apis mellifera to anti-Varroa destructor formic acid treatment induces significant proteomic alterations

ArticlesBy RachelWard 13. April 2023

The parasitic mite Varroa destructor is a major threat to the health and productivity of Apis mellifera hives and induces its effect by feeding on the fat body of larvae/pupae and transmitting viruses. The effect of the anti-Varroa formic acid containing – Mite Away Quick (MAQ) strips on the proteome of A. mellifera was assessed.…

Be aware the Tropilaelaps mite is spreading!

ArticlesBy VictoriaSoroker 13. April 2023

Members of COLOSS have recently been reporting that the Tropilaelaps mite, which has previously been confined to eastern parts of Asia, has been spreading on Apis mellifera towards the west, and has been detected in Uzbekistan, south -western parts of Russia and possibly Iran. In view of this threat, we feel that there is an…

The value of insect pollination to yield of oilseed rape (Brassica rapa) in Bangladesh

ArticlesBy RabiulIslam 13. March 2023

Abstract Brassica rapa L., is a crop grown globally and studies have indicated that insect pollination can improve yields. However, the importance of insect pollination in this crop depends on cultivar reproductive biology, insect pollinator species and their abundances. In Bangladesh, the acreage of B. rapa for oilseed production has been expanding, but little is…

Proteomic analysis of summer and winter Apis mellifera workers shows reduced protein abundance in winter samples

ArticlesBy RachelWard 10. March 2023

Apis mellifera workers display two stages; short lived summer bees that engage in nursing, hive maintenance and foraging, and long lived winter bees (diutinus bees) which remain within the hive and are essential for thermoregulation and rearing the next generation of bees in spring before dying. Label free quantitative proteomic analysis was conducted on A.…

4-Year Overview of Winter Colony Losses in Greece: Citizen Science Evidence That Transitioning to Organic Beekeeping Practices Reduces Colony Losses

ArticlesBy EvangeliaKagiali 20. February 2023

The honey bee is one of the most important pollinators with a close relationship to humans. The questionnaire from the non-governmental association “COLOSS”, answered by beekeepers around the world, is a valuable tool for monitoring and analyzing factors involved in overwintering losses, as well as for understanding the evolution of the beekeeping sector over the…

Exploring the impact of RF-EMF exposure on planetary health

ArticlesBy MariaBouga 16. February 2023

Approaches to assess the impact of emerging technology from a planetary perspective, while exploring options for exposure reduction and interacting with citizens and stakeholders about exposure levels and possible associated risks. Following a citizen science paradigm, ETAIN will develop an app and a platform able to quantify one’s personal exposure to RF-EMF (Radiofrequency Electromagnetic Fields).…

Nationwide Screening for Bee Viruses in Apis mellifera Colonies in Egypt

ArticlesBy YahyaAlNaggar 14. February 2023

Honey bees are essential for crop and wild plant pollination. However, many countries have reported high annual colony losses caused by multiple possible stressors. Diseases, particularly those caused by viruses, are a major cause of colony losses. However, little is known about the prevalence of honey bee pathogens, particularly virus prevalence, in Egyptian honey bees.…
