Species in News: Western Honey Bees

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Western Honey Bees

Why in the News?

  • Western Honey Bees widely used for boosting pollination has led to unintended ecological consequences.
    • Now they inadvertently carry and transmit Thai Sacbrood Virus to native bee colonies.

About Western Honey Bees

  • Scientific Name: Apis mellifera
  • Introduced globally for their pollination abilities and honey production. In India, they were introduced in 1983 to enhance honey yield.
  • Widely used in agriculture, particularly for pollination of crops like fruit trees, crops, and vegetables.

Thai Sacbrood Virus Outbreak

  • The Thai Sacbrood Virus (TSBV) outbreak in China and Vietnam has severely impacted honey bee populations.
    • In 1991-1992, a Thai sacbrood virus outbreak devastated around 90% of Asiatic honey bee colonies in South India and re-emerged in 2021 in Telangana.
  • The virus primarily infects honey bee larvae, leading to their high mortality rates.
  • As a result, the affected regions experienced significant declines in bee colonies, which in turn affected pollination services and honey production.
  • The movement of bee colonies for commercial pollination and honey production has facilitated the spread of the virus.

About Indian Bees and Their Habitat

  • Indian bees are predominantly Apis cerana indica, a species of Asian honey bee.
  • They are found in a wide range of habitats, including forests, agricultural land, and urban environments.
    • They thrive in areas with abundant flowers and nectar sources.
  • Indian bees are important for pollination, especially for local flora, and contribute to the ecosystem by supporting biodiversity and food production.
  • They face threats from habitat loss, pesticide use, and competition from Western Honey Bees, which may outcompete them for food and nesting sites.

Significance of Honey Bee: 

  • Pollination and Food Security: Honey bees play a crucial role in pollinating crops, contributing to the production of fruits, vegetables, and nuts, ensuring global food security and agricultural sustainability.
  • Biodiversity Conservation: By facilitating plant reproduction, honey bees support ecosystem health and biodiversity, maintaining the balance of natural habitats and enhancing the resilience of ecosystems.
