Tetragonula yikhumensis

WHY IN NEWS  

Researchers discovered a new stingless bee species in Wokha district, Nagaland.

Basic Facts

• Scientific name: Tetragonula yikhumensis.

• It belongs to the genus Tetragonula.

• It was named after Yikhum village, where it was first collected.

• Discovery location: Wokha district, Nagaland.

Key Features

• It is a subterranean, or underground-nesting, stingless bee.

• It has a large body, unique morphology and distinctive nest architecture.

• Body length: About 5.59 mm.

• It is the largest stingless bee recorded in India.

Nesting Behaviour

• Colonies are built more than 2 metres below the ground.

• Nests contain separate honey, pollen-storage and brood chambers.

• The chambers are protected by hard batumen layers.

• Batumen is a mixture of wax, plant resins and other materials.

• Narrow tunnels connect the underground nest to the surface.

Why is the Discovery Important?

• India now has 26 known stingless bee species, up from 25.

• The genus Tetragonula now has 18 recorded species in India.

• It is only the second underground-nesting Tetragonula species documented in India.

• It improves our understanding of India's pollinator diversity and bee evolution.

Traditional and Ecological Importance

• The Lotha community calls these bees 'Litsuk' or 'Ground Bees'.

• Their honey and pollen are traditionally valued for medicinal properties.

• Stingless bees pollinate wild plants and crops.

• They support crop productivity, biodiversity, ecosystem stability and sustainable agriculture.

QUICK RECALL  Nagaland • Yikhum village • 5.59 mm • Largest stingless bee in India • Underground nest >2 m

Picrorhiza kurroa (Kutki)

WHY IN NEWS  

A sustainable cultivation model in Mandi district, Himachal Pradesh, is helping conserve the endangered medicinal plant Kutki.

About Kutki

• Picrorhiza kurroa is a perennial medicinal herb with underground rhizomes.

• Its common name is Kutki.

• The name comes from Greek: 'Picros' means bitter and 'Rhiza' means root.

Habitat and Distribution

• It grows in alpine and sub-alpine Himalayan regions at 2,700-4,500 metres.

• In the Himalayas, it occurs from Garhwal to Bhutan and from Kashmir to Sikkim.

• It is also found in Pakistan, Tibet, western China and Myanmar.

Climate and Soil

• It prefers moist, north-west-facing and less exposed slopes.

• Sandy clay soil is ideal.

• Porous soil helps rhizomes spread horizontally and new shoots emerge from nodes.

• Prolonged and intense rainfall causes high mortality.

Propagation

• It is initially propagated through seedlings.

• It can also grow through rhizomes, stolons and offsets.

• Stolons are creeping stems with nodes. They spread over the soil and produce new plants.

Medicinal Uses

• Widely used in Ayurveda and traditional medicine.

• Properties: Anti-pyretic, anthelmintic, carminative, stomachic, hepatoprotective, anti-malarial and laxative.

• In large doses, it acts as a cathartic.

• It improves appetite and stimulates gastric secretions.

• It is used for asthma, cold and cough.

Conservation Status

• IUCN Red List: Endangered.

• CITES: Appendix II.

QUICK RECALL  Kutki • Bitter root • 2,700-4,500 m • Endangered • CITES Appendix II
