Since 2021, the Ministry of Planning and Development has been collaborating with the United Nations Development Programme (UNDP) to implement the Biodiversity and Ecosystem Services Network TT (BES-Net TT) project. The project serves to bring awareness and improve the management of local pollinators in Trinidad and Tobago.

A main group of pollinators, the native stingless bees or Meliponini is singled out for special attention. On the occasion of World Bee Day today, this article shines a light on these bees and the work being done through BES-Net TT to assist in their conservation.

Introducing stingless bees

Throughout the life of the BES-Net TT project, any interaction with the public to promote activities and objectives in stingless bee management has yielded the question, “There are stingless bees?” These native organisms have lost the spotlight to their exotic, honey-producing cousins, the European honeybee (Apis mellifera), which in Trinidad are mainly the "Africanised honey bee" poly-hybrid, while in Tobago the milder European honeybees are reared, a media release said.

Stingless bees are so-called as they do not sting, and do not possess that appendage for defence. Several of them are mild-mannered, with perhaps just one species – Trigona amalthea (“Pegone”) – that may issue a "nip" with its mouthparts to defend itself.

In general, the bees range in size from about as large, to about half the size of a honeybee. One species – Melipona favosa (Moko Chiquita) – has banding patterns like a honeybee, with yellow stripes alternating with cinnamon brown bands. Most of the local species are black in colour, slim-bodied and may be mistaken for flies or wasps. Stingless bees live in colonies, some species creating circular, horizontal brood combs stacked like pancakes, and others creating brood cells that look like a mass of tiny grapes.

Busy, beneficial bees

Stingless bees perform important roles, contributing to food production and the plant reproductive cycle through the process of pollination. Some species have preferred plants to visit, to obtain nectar and pollen; for example, Friesiomelitta paupera (Petit angel) is a main pollinator for avocado and Nannotrigona testaceicornis (Irai) visits cucumber and tomato flowers.

Some species are prized for their hive products, with some producing a type of honey – which generally has a higher moisture content than honey from honeybees – used more for medicinal properties than as food. In parts of Latin America, this type of honey is used in wound treatment. Within TT, it is a low volume, high value product, traded among local keepers and users familiar with these properties.

A need to conserve
