Detailed Summary

World Bee Day is observed globally on May 20 every year. The United Nations designated May 20 as World Bee Day in December 2017, on the proposal of Slovenia. The date commemorates the birth anniversary of Anton Janša (born May 20, 1734), a pioneer of modern beekeeping from Slovenia. The theme for World Bee Day 2026 is "Bee Inspired by Nature to Nourish Us All." The day aims to raise awareness about the vital role bees and other pollinators play in maintaining biodiversity, ensuring food security, and supporting sustainable agriculture. Globally, bees pollinate approximately 75% of food crops and 90% of wild flowering plants. In India, bees and other pollinators are critical for crops like coconut, mango, cardamom, sunflower, cotton, and vegetables. The declining bee population globally — due to pesticide use, habitat loss, monoculture farming, climate change, and invasive species — is a major ecological and agricultural crisis.

Key Facts

Ecological and Agricultural Importance of Bees

• Bees pollinate ~75% of major food crops globally
• Over 80% of flowering plants depend on insect pollinators (primarily bees)
• Annual economic contribution of pollination: estimated at ~$577 billion globally
• Without bees: reduced crop yields, lower biodiversity, ecosystem collapse risk
• Key crops pollinated by bees in India: Mango, Coconut, Cotton, Cardamom, Sunflower, Apple, Mustard, Lychee

Tamil Nadu Relevance

• Tamil Nadu is a major producer of Honey — Nilgiris district bees produce unique honey varieties
• Tamil Nadu horticulture crops like Mango (Alphonso, Banganapalli varieties), Coconut, Banana depend on pollination
• The Nilgiri Biosphere Reserve supports diverse native bee species including Apis cerana indica and Apis dorsata (rock bee)
• Tamil Nadu Government promotes beekeeping through the Horticulture Department as an income supplement for rural farmers

Threats to Bees

• Pesticides (especially neonicotinoids) — damage nervous system of bees
• Habitat loss due to urbanization and monoculture farming
• Climate change altering flowering seasons — causing mismatch with bee activity cycles
• Invasive species — Varroa mite parasite destroys honeybee colonies
• Disease and pathogens affecting bee colonies

Important Terms and Definitions

• Pollination: The transfer of pollen from the male part (anther) to the female part (stigma) of a flower — required for fertilization and fruit/seed production.
• Apiculture: The scientific practice of maintaining bee colonies in hives for honey production and pollination services.
• Apis mellifera: The European honeybee — most commonly domesticated bee species worldwide.
• Apis cerana indica: The Indian honeybee — native Asian honeybee species important for Indian agriculture.
• Varroa Mite: A parasitic mite (Varroa destructor) that attacks and weakens honeybee colonies — one of the biggest threats to bee populations globally.
