Pollinator biodiversity research
Bee taxonomy is essential for pollination biology, pollination management and biodiversity conservation. Because pollination is often an intricate interaction between the plant and the pollinator, it is essential to correctly identify the organisms involved. There are 2755 bee species in sub-Saharan Africa, about a third of which occur in South Africa.
Pollination mostly precedes fruit and seed production and many plants, including many crops, are insect pollinated. Bees are the most important group of pollinators.
Around the World bee abundance and diversity is diminishing. This affects agriculture and biodiversity conservation and we cannot understand and rectify the problem if we don’t know the organisms involved.
Dr Connal Eardley
Almost all bees are pollinators, but only a few species make honey. The honey makers are the honey bee (one species) and the mocca or mopani bees (10 species), and even these honey producers are very important pollinators. Pollination precedes fruit and seed production and therefore it is an ecosystem service, the cost of which is the maintenance of pollinator healthy ecosystems.
Pollination is a difficult subject because different crops and wild plants need different pollinators. The pollinators may differ in different areas and periods of the season. Further, most plants have a complex of pollinators, and similarly many pollinators visit several plant species. Both pollinator and plant biodiversity together maintain pollinator healthy ecosystems. This complex situation is, in essence, biodiversity a biodiversity is in itself an ecosystem service.

The Aculeate Hymenoptera collections
The bee collection of the S.A. National Collection of Insects comprises about 50 000 bee specimens. Material belonging to genera that have been revised are identified. Currently the Megachilidae are being studied.
The aculeate wasp collection comprises about 40 000 specimens. They have not been databased. Specimens in genera that have been revised are mostly identified.
Material is made available to researchers interested in studying Afrotropical bees and aculeate wasps.
