Biodiversity and Challenges of Honey Bee Population in Pakistan
Summary
This review examines the biodiversity and ecological challenges facing honey bee populations in Pakistan, covering threats from habitat loss, pesticide use, disease, and climate change. The authors assess the status of native bee species and managed colonies and discuss implications for agricultural pollination services and food security in the region.
Honey bees are important pollinators that support food security and nature’s biodiversity. They are also a source of various honey bee-derived products (api-products) used in the food, pharmaceutical, and cosmetic industries. However, various biological, chemical and physical factors threaten the population and biodiversity of feral and managed honey bees. These challenges have not been elaborated upon in the Pakistani context; therefore, this review aims to identify and describe the menaces to feral and domesticated populations of honey bees in Pakistan. Four honey bee species are reported in the country, with the Western honey bee (Apis mellifera) currently being the main domesticated species. Climate change and urbanization are altering the habitats of honey bees. Additionally, agrochemicals are extensively used to manage emerging pests, exacerbating environmental pollution. The air quality in the majority of urban areas is toxic for honey bees. Although remote forest areas can provide habitat and food for these insects, low forest cover and non-sustainable silviculture are still significant hurdles. Microplastics and antimicrobials are impacting the fitness of honey bees and also appear in their products, making it a One-Health issue. Electromagnetic signals also influence honey bee health and behavior. Overall, all these factors influence honey bee health and colony fitness, ultimately causing population declines in both managed and wild honey bees. The purpose of this information is to assist decision-makers, researchers, beekeepers and educators in comprehending the obstacles faced by the honey bee population within the context of Pakistan.

Biotic and abiotic stresses on honeybee health
This review covers the many threats facing honeybee health, including parasites, pesticides, habitat loss, climate change, and emerging pollutants like microplastics. Microplastics have been found in bee habitats and can be ingested during foraging, potentially affecting bee health and colony survival. Since honeybees are essential crop pollinators, threats to their health from microplastic pollution could indirectly impact human food production.
The Role of Beekeeping in the Generation of Goods and Services: The Interrelation between Environmental, Socioeconomic, and Sociocultural Utilities
This review examines the diverse ecosystem goods and services generated by beekeeping, including pollination, honey production, and cultural benefits, while documenting growing threats to bee populations from pesticides, habitat loss, and emerging pathogens. The authors argue that beekeeping supports biodiversity and food security in ways that are systematically undervalued in economic and environmental assessments.
Microbiota and Its Importance in Honey Bees
This review examines the role of microbiota in honey bee health, finding that gut microbiome composition is critical for metabolism, immune function, and protection against pathogens, with environmental stressors including pollution threatening bee microbiome stability.
The Honey Bee Apis mellifera: An Insect at the Interface between Human and Ecosystem Health
This review provides an updated overview of the many ways honey bees benefit both human societies and natural ecosystems, from pollinating crops and wild plants to producing honey and serving as environmental monitors. Researchers highlight the bee's role as a bioindicator species that can reveal pollution levels, including microplastic contamination, in the environment. The study underscores how threats to honey bee health, including exposure to environmental pollutants, can have cascading effects on food security and biodiversity.
Developing Strategies to Help Bee Colony Resilience in Changing Environments
This review identified strategies for improving bee colony resilience under multiple stressors including climate change, pathogen pressure, and pesticide exposure, with a focus on the links between nutrition, gut microbiota, and immune and stress response systems. The authors highlight dietary diversity and microbiome support as practical levers for maintaining colony health.
