Recently, scientists at the CSIR-Indian Institute of Integrative Medicine (IIIM), Pulwama, successfully demonstrated that Apis mellifera can survive sub-zero temperatures.

About Apis mellifera

Apis mellifera, commonly known as the Western Honey Bee or European Honey Bee, is the most widely distributed and commercially important species of honey bee in the world.

It is regarded as the most extensively domesticated insect species and plays a crucial role in honey production, beeswax production, pollination services, and agricultural productivity.Because of its efficiency in pollinating crops, Apis mellifera is considered one of the most economically valuable insects for global agriculture.

Habitat and Distribution

Apis mellifera is native to Europe, Western Asia, and Africa. However, beginning in the seventeenth century, humans introduced this species to many other parts of the world.

Today, it is found across almost all continents, including Asia, Australia, North America, and South America.The species thrives in areas that provide an abundant supply of flowering plants. It commonly inhabits meadows, gardens, agricultural fields, and open woodland areas. it can also survive in grasslands, deserts, and wetlands, provided that sufficient food, water, and shelter are available.

Physical Characteristics

The Western Honey Bee is generally reddish-brown to yellowish in colour, with distinct black bands and orange-yellow rings on its abdomen.

It possesses two pairs of wings, a slender waist, and a body covered with fine branched hairs that help collect pollen from flowers.

These hairs are especially important in facilitating pollination, as pollen grains easily attach to them and are transported from one flower to another.

Social Organization

Apis mellifera exhibits eusocial behaviour, representing one of the most advanced forms of social organization found in insects.

Each colony consists of:

• A single fertile female known as the Queen.

• Thousands of sterile female Worker Bees.

• A relatively small number of fertile male bees called Drones.

A single colony can contain tens of thousands of individuals, functioning together as a highly organized social unit.

Stinging Mechanism

Both worker bees and queens possess venom-producing stingers.

Nest Structure

The nests of Apis mellifera display remarkable architectural complexity. They are made up of multiple hexagonal combs constructed from beeswax secreted by worker bees.

Economic Importance

Apis mellifera is commercially exploited for several valuable products, including honey, beeswax, propolis, royal jelly, and bee venom.

Recently, China completed an 11.18-kilometre-long high-speed underwater tunnel beneath the Yangtze River. The tunnel is designed to facilitate the movement of bullet trains at speeds of up to 350 km/h.

About the Yangtze River

The Yangtze River, known in China as Chang Jiang or Yangzi, is the longest river in China and Asia and the third-longest river in the world, after the Nile River and the Amazon River.

The river is approximately 6,300 kilometres long and is also regarded as the longest river that flows entirely within a single country.

Course of the River

The Yangtze River originates in the mountainous regions of Tibet and flows eastward across China.

For much of its journey, the river passes through mountainous terrain, deep valleys, and gorges. As it approaches eastern China, it enters broad and fertile plains before finally emptying into the East China Sea near Shanghai.

Major Tributaries

The Yangtze River has eight principal tributaries.

On the left bank, the major tributaries are:

• Yalung River

• Min River

• Jialing River

• Han River

On the right bank, the important tributaries are:

• Wu River

• Yuan River

• Xiang River

• Gan River

These tributaries significantly contribute to the river's volume and support agriculture, transportation, and settlements across the basin.

Economic Importance

The Yangtze River has been one of China's most important transportation routes since the thirteenth century. It connects inland regions with coastal ports and links major cities such as Nanjing, Wuhan, and Chongqing.

The river serves as a vital commercial artery, facilitating the movement of goods and people across the country.

Agricultural Importance

The Yangtze Basin is often referred to as China's Great Granary because of its immense agricultural productivity.

Nearly half of China's agricultural crops are grown within the basin. The fertile alluvial soils, abundant water supply, and favourable climate make the region ideal for intensive farming.

The basin is particularly important for the cultivation of rice, wheat, cotton, and oilseeds.

Fisheries and Industry

The Yangtze Basin is also one of China's most important fishing regions. It provides approximately half of all the fish consumed in China, making it crucial for food security and livelihoods.

Population and Urban Centres

The Yangtze River Basin supports a population of around 400 million people, accounting for nearly one-third of China's population.

A recent report of the Kerala State Food Commission highlighted significant irregularities in the distribution of ration supplies in Edamalakkudy, which is Kerala's only tribal panchayat and is predominantly inhabited by the Muthuvan tribe.

About the Muthuvan Tribe

The Muthuvan Tribe, also known as Mudugars, is an indigenous tribal community inhabiting the Western Ghats of Kerala and Tamil Nadu.

The Muthuvans are known for their deep connection with forests and mountains. Over generations, they have developed extensive traditional knowledge about the ecology of the hills and have learned to coexist harmoniously with wildlife. The community is also renowned for its expertise in traditional medicine. Knowledge of medicinal plants and healing practices is carefully preserved and passed down through generations.

Language

The Muthuvans speak the Muthuvan language, which belongs to the Dravidian language family.

Within the tribe, there are two major groups that speak slightly different dialects. These groups identify themselves as Malayalam Muthuvan and Pandi Muthuvan, reflecting linguistic and regional variations within the community.

Social Organization

The social structure of the Muthuvan tribe is highly organized and based on a traditional clan system.

The community is divided into six clans known as “Koottams.” Each koottam is further divided into smaller sub-clans. These clan divisions play an important role in regulating marriage alliances, maintaining social status, and preserving ancestral lineage.

The Muthuvans follow the practice of community endogamy, which means marriage takes place within the tribe. At the same time, they practice clan exogamy, requiring individuals to marry outside their own clan.

One of the most distinctive features of Muthuvan society is the “Kani System” of governance. Under this traditional system, the affairs of the community are managed by a council of elders headed by a leader known as the Kani.

Religion and Beliefs

The Muthuvans traditionally practice animism and spirit worship. They believe in the presence of spiritual forces in nature and worship various forest deities.

Occupation and Livelihood

Agriculture remains the primary occupation of the Muthuvan tribe. Their traditional farming practice is known as Virippukrishi, a form of shifting cultivation that has been followed for generations.

The crops cultivated by the community are mainly intended for self-consumption rather than commercial sale. This reflects their subsistence-based economy and self-reliant way of life.

The major crops grown by the Muthuvans include Ragi (Little Millet), Maize, Thina (Italian Millet), Varagu, Chama Rice, Tomato, Carrot, Sweet Potato, Potato, Cheeni Vala, Toppi, and Mocha. These crops form an essential part of their diet and contribute to their food security.

Key Features of the Muthuvan Tribe

The Muthuvan tribe is known for its strong clan-based social structure, traditional Kani governance system, rich knowledge of medicinal plants, and harmonious coexistence with forests and wildlife. Their unique cultural practices, indigenous knowledge systems, and sustainable lifestyle make them one of the most significant tribal communities of the Western Ghats region
