Bees are vital to ecosystems, playing a crucial role in maintaining biodiversity, ensuring plant survival, promoting forest regeneration, adapting to climate change, and improving agricultural production. Close to 75% of the world’s crops producing fruits and seeds for human consumption rely on pollinators for sustained production, yield, and quality. Beekeeping, or apiculture, involves the practical management of social bee species.
Beekeeping differs from honey-hunting, which involves plundering wild nests. For thousands of years, humans have encouraged bees to nest in man-made hives for easier honey extraction and colony management. Beekeeping is widespread in many rural areas, with thousands of small-scale beekeepers relying on bees for their livelihoods.
Social bees provide valuable hive products such as honey, wax, propolis, pollen, royal jelly, queen bees, and swarms. They also offer services like pollination, apitherapy, apitourism, and environmental monitoring, playing significant economic, cultural, and social roles.
Across the world, several bee species are kept. Western honeybees (Apis mellifera) are standard in Europe, America, and West Asia, while the indigenous Eastern or Asiatic honeybee (Apis cerana) is kept in East and South Asia.
South Africa's Western Cape is home to a unique honeybee subspecies called Apis mellifera capensis, or Capensis. These bees can reproduce without a queen. While honey is extracted, it is only done so from strong hives with a surplus and at appropriate times.

The Africanized Honey Bee (AHB) and Management Practices
The Africanized honey bee (AHB) presents unique challenges, requiring beekeepers to rethink their management practices. Evidence suggests that Africanized honey bees are often more manageable in the dark, a stark contrast to European honey bees. Honey harvesting at night is a common practice in South Africa, where beekeepers use red lights that bees perceive as dark.
One method uses beehives on platforms for easy movement. The bees are smoked, and the hive is moved at right angles from the flight path, reducing the number of bees left in the hive. The comb is then collected quickly and placed in a covered receptacle, and the hive is returned to its location. Daylight harvesting is advantageous for efficiency, brood nest control, and disease/predator detection.
It is crucial to remember that the Africanized honey bee is still a honey bee, and beekeepers must adapt to its behavior. The most noticeable behavior, stinging, can be extreme, with bees being gentle at times but highly defensive at others.
Adapting to the Africanized Honey Bee
One beekeeper's experience in southern Mexico highlights the need for preparation when dealing with AHB:

- Large smokers are essential.
- Full bee suits with ankle protection are necessary, as managing hives without protection is no longer viable.
- Colonies should be kept 100 meters from houses, roads, or livestock to prevent stinging incidents.
Other issues include swarm control, requeening, and preventing vandalism.
European-style bee houses are particularly useful in urban areas because they:
- Keep colonies out of sight.
- Facilitate manipulation under all weather conditions.
- Calm colonies by providing constant shade.
Challenges Facing the South African Beekeeping Industry
The beekeeping industry in South Africa faces numerous challenges that threaten its sustainability. These include:
- Aging beekeepers
- Low honey prices
- Inadequate training
- Vandalism
- A scarcity of young commercial beekeepers
These issues have raised concerns about the future of apiculture in the country.
Innovative Solutions: The AgriSound Project
To address these challenges, a collaborative project involving CHAP, Agrisound, and Cropimpi aims to introduce in-hive sensor technology to provide real-time decision support for South African beekeepers. These sensors measure colony acoustics, temperature, humidity, light, and motion detection to identify potential hive theft.

The project's first phase focused on the KwaZulu Natal province, home to the African honeybee species. Twenty-five participants from diverse backgrounds were selected and provided with comprehensive online training modules covering hive health, installation, components, and beekeeping tips. The training materials were tailored based on an initial survey that assessed the beekeepers' skills and experience.
As part of the first phase, 100 AgriSound in-hive sensors were distributed among the participating beekeepers. The success of this phase validated the demand for improved beekeeping practices and confirmed the viability of using 3G/4G connectivity for IoT devices.
The project's next phase involves gathering data from in-hive sensor devices in KwaZulu Natal and the Western Cape provinces. The team will also organize knowledge dissemination events in Cape Town and at the Honey Festival in KwaZulu Natal.
Project Outcomes and Benefits
The project demonstrated the positive value of in-hive monitoring technologies. From the 200 in-hive sensors installed across 43 participants, 47% noted reduced time spent monitoring hives, and 63% reported quicker action on their hives. This increased customer awareness and demand for the product, with 87% of participants wanting to continue using the technology and 71% willing to pay for it.
The types of corrective actions taken included:
- Temperature control (moving the hive into the sun/shade/removing super)
- Humidity control (tilting hive to remove excess water)
- Introduction of a new queen (following the identification of severe temperature fluctuation of hive)
- Honey harvest (stable temperature recorded indicating the box was full and ready to harvest)
- Preventing splitting of hive by addition of super (due to lack of space in the hive thus inducing swarming)
The needs and priorities identified by beekeepers included theft protection/identification (23%), opportunity to learn more about their hives (33%), early/remote detection of issues (16%), opportunity to save money/time/fuel to visit hives (10%) and reduce swarming (10%).
The overall data showed that 47% said it reduced time spent monitoring hives, and 63% said it enables them to take quicker action on their hives. Furthermore, 20% of participants recorded increased yield as a result of using the device.
While it is too early to know whether they have a tangible impact on honey productivity, there are strong indications that the sensors devices help to reduce time of beekeeping.
| Metric | Percentage |

| Participants taking corrective actions | 43% |
| Participants finding training helpful | 97% |
| Participants valuing the technology | 70% |
| Participants willing to pay for the technology | 71% |
| Participants reporting reduced time monitoring hives | 47% |

Cost Model and Local Manufacturing
To make the in-hive devices more accessible, the optimum price point was shown at R600-1000 (£25-40) for a gateway and four sensors, with a monthly data fee of R99 (£5/pcm). The current level of price sensitivity means that the existing business model is not viable and indicates a need to identify new more affordable solutions.
Several options were considered, including local manufacturing, and sponsorship and/or subsidies. A deep-dive into local manufacturing showed that several electronics manufacturers are present in the region and have the ability to produce the hive monitoring technology. However, this option was ultimately discounted.
Promisingly, the rise of an ‘agri-fintech' sector presents a great opportunity to spread the cost of the hardware over a multi-year period through an asset financing model. Simple modelling suggested that spreading the cost over a 5-year period could make the technology accessible to most end-users and aligns with their willingness to pay. The potential for support and subsidies from both international foundations and local government agencies is substantial.
Community-Led Initiatives: Ruliv's Approach
In the Eastern Cape, Ruliv, a non-profit organization, is working alongside communities to strengthen community-led solutions tailored to local needs. Ruliv has established farmland across three sites, planting vegetables for household consumption and income generation. The gardens are grounded in a participatory approach, where communities are taking a leadership role.
Community members also requested diversification through beekeeping, with technical support provided by experienced beekeepers and permaculture experts. The initiative began with a pilot garden and training in organic farming practices for 60 community members.
Beekeeping as a Complementary Livelihood
Beekeeping has emerged as a complementary livelihood opportunity, with added benefits for local ecosystems and biodiversity. Under the mentorship of Vincent Shaw, 18 new beekeepers were trained, and five now actively manage hives and have established a local beekeepers’ association.
Five hives have been strategically placed across the Amatole Basin, with support from Shaw in transferring wild hives and queen bees to ensure sustainability. The new beekeepers expressed their determination to look after bees, recognizing the importance of bees as part of nature, not just for honey.
Varroa Mites and Bee Pathology
Consideration of the Varroa situation in South Africa as well as the rest of the world falls under the Bee Pathology Standing Commission. Treatment of Varroa was the largest symposium in Durban as might be expected and took two full sessions. Alsopp, treatment will artificially sustain the susceptible honey bee population, and will prevent the development and spread of a naturally-selected Varroa resistant population.
Hence, a comprehensive response to the Varroa threat is required, involving Integrated Pest Management (IPM) strategies, further research, and regional, governmental and legal strategic actions.
At the South African Apimondia meeting, Dr. Anderson reported that over twenty genotypes of newly-named Varroa destructor and newly-defined Varroa jacobsoni now exist. According to Dr. Anderson, the Korean genotype has the widest geographical distribution, affecting A. mellifera in the Europe, the UK, Russia, the Mediterranean, the Middle East, North Africa, Asia, North and South America, Canada and New Zealand (and now identified in South Africa).
