Martin Boima stands under a large mango tree in Mopye, a village in northeast South Africa, and eats crispy dried termites. He ate that insects, known locally as “Makeke” since he was a little boy who lured them out of their mounds with long strips of grass and dried or fried them.
Today he distributes homemade termite protein bars, which are available in cheese or chocolate flavor, to an excited village people. It’s part of a series of taste tests he’s doing in his new insect-based food business.
He is joined by Bronwyn Egan, a zoologist from the University of Limpopo in South Africa, who shares his fascination with edible insects on a culinary and academic level. For the past two years she has worked closely with Boima and other locals, building her knowledge of both nutritious animals and actual specimens.
Enriching science with traditional knowledge
She wants to build a scientific understanding of these species as a first step towards their conservation. Some estimates say up to 40% of insect species could be extinct worldwide in the decades to come – mainly due to habitat loss as land is turned into intensive agriculture, as well as urbanization and pesticide use.
Termites are lured out of their mounds
Egan fears that poor insect taxonomy in South Africa makes it particularly difficult to accurately understand the extent of biodiversity loss. “We don’t even have names for all the things that are lost every day,” she said. Enriching science with traditional knowledge Egan hopes her project will help conservation for insects, which are a particularly valuable source of food for communities.
Catching, cooking, and eating insects as a whole is common in many parts of rural South Africa, including the lush, mountainous Bolobedu South area of Limpopo, where Boima lives. He says he “loves insects” for their earthy, nutty taste. “However you want to cook them – they’re always nice.”

Boima and other field workers share the names, whereabouts, and behavior of local edible species with Egan to help protect and promote insects and the traditional knowledge that is close to his heart.
Today he shows her how he catches his dinner in the fields next to his village. He shakes plants with a green branch and causes locusts – or “ditšie” – to jump into his waiting hands.
Bar coding biodiversity
Part of his bounty goes into a plastic bag for Egan’s lab, where she keeps the samples in alcohol and records her identity information. A selection of the specimens received will then be sent nationwide to Barbara van Asch, lecturer at the Institute for Genetics at Stellenbosch University.

Van Asch sequences the insects’ DNA to create a genetic barcode. This information, along with other classifications such as genus and scientific name, is then added to databases such as the International Barcode of Life – a global library of genetic information for various species aimed at protecting biodiversity.
So far, Van Asch’s Limpopo Samples have provided nine “ethno-species” groups of animals identified by local communities rather than Western scientific classification systems. This type of work was done on other edibles insect Population in Asian countries, but African knowledge has often been overlooked by academic science, explained van Asch. “It’s like bringing them to life,” she said. “But only on our side, because on the side of the communities they [already] exist.”
Environmental threats
From the field where he caught the locusts, Boima points to a spot on the other side of a green valley that used to be rich in insects. Now there is hardly any left, he explains, and the leaves are starting to turn brown. He suspects the landowner sprayed pesticides in preparation for converting the land for development or agriculture.
Scientist Bronwyn Egan wants to use traditional knowledge about insects to support research and conservation
Egan and van Asch see their identification work as an essential first step towards conservation. “If it doesn’t have a name, no one will prevent a building from being erected for an unnamed cause,” says Egan. They hope that this foundation of scientific knowledge will inform researchers and activists who want to track and defend insect populations.
Commercialization insects
They also see the potential it has to aid in the commercialization of human insect-based food Animal feedwhich has gained momentum in recent years. Consumers can now buy cricket protein in the US or insect ice cream in South Africa. “They only need a very small amount of resources compared to their nutritional value,” said van Asch.
Insects were highlighted as being more sustainable alternative Meat protein as it uses less water, less land and produces fewer greenhouse gas emissions.
In addition to the continued barcode work, Van Asch plans to provide funding for pilot projects to test how households in South Africa can set up small farms. The results of her research with Egan will help determine which species might be suitable.
A study This year, the University of Bonn came to the conclusion that while insect breeding has growth potential as a sector, more research is required on the suitability of the species and the investment and political framework conditions required for this.
However, Egan believes that combining traditional knowledge from areas like Limpopo with scientific data could help identify which species could be commercialized. For example, these soldier termites, which occur year round, would be a better choice than the seasonal flying termites.
Boima plans to start selling its termite protein bars soon and eventually hopes to employ others in the area. He is also interested in teaching people the value of this traditional knowledge. “We need to know that these insects are very important to our culture and that we can live because of them,” he said. “So we have to take care of them.”
