Warmer weather makes feeding time much easier, and more effective, for honeybees, according to Professor Sue Nicolson of the University of Pretoria (UP) and colleagues from Chinese universities, who made this discovery after analysing high-speed videos. The results were published in the Journal of Experimental Biology.

Most people have a perception that beehives and colonies are perfectly built, and that they are places of industrious labour for the greater good of the colony and a workforce working for the common good. Prof Crewe’s research uncovers the “dark” side of bees.

Once upon a time there was a world without bees, but we would not have liked this world. It was a dark world without flowering plants competing to attract buzzing bees for pollination—a world without colourful fruits and berries. Even after solitary bees emerged, it took many millennia before bees became social and a colourful and sweet world, a place with nectar, emerged.

A species of mosquito that can carry malaria – known as Anopheles stephensi – has invaded eastern Africa and is quickly moving across the region. Moina Spooner, from The Conversation Africa, asked Jeremy Herren and Clifford Mutero to provide insights into why this invasion is happening and what can be done to protect people from it.

The polyphagous shot hole borer (PSHB) is a tiny, invasive black beetle from Asia that has recently been discovered in South Africa. Although only 2 mm in length, this tiny beetle has detrimental consequences for South African trees, as it carries a destructive fungus, Fusarium euwallaceae, from tree to tree.
