Africa: The First Fossil Thrips in Africa – This Tiny Insect Pest Met Its End in a Volcanic Lake 90 Million Years Ago

Published

Thrips are tiny insects – their sizes range between 0.5mm and 15mm in length and many are shorter than 5mm. But the damage they cause to crops is anything but small. A 2021 research paper found that in Indonesia “the damage to red chilli plants caused by thrips infestation ranges now from 20% to 80%”. In India, various thrips infestations in the late 2010s and early 2020s “damaged 40%-85% of chilli pepper crops in Karnataka, Andhra Pradesh and Telangana”.
In Africa, a number of thrips species feed on sugarcane and have been known to damage nearly 30% of the crop in a single hectare of a farm. High rates of destruction have been recorded in Tanzania and Uganda on onion and tomato crops.
Now it’s emerged that thrips are hardly new to the African continent and the southern hemisphere more broadly. South Africa’s first and only Black palaeoentomologist, Sandiso Mnguni, who studies fossil insects, recently described a fossil thrips from Orapa Diamond Mine in Botswana that’s more than 90 million years old. He discussed his unique fossil find with The Conversation Africa.
What are thrips and how do they cause damage?
Thrips, also known as thunderflies, thunderbugs or thunderblights, are small, slender and fragile insects. They can be identified by their typically narrow, strap-like, fringed and feathery wings. Over time, they have also evolved distinctive asymmetrical rasping-sucking mouthparts consisting of a labrum, labium, maxillary stylets and left mandible. Most species use these to feed primarily on fungi. Some feed on plants and eat the tender parts of certain crops like sugarcane, tomatoes, pepper, onions, avocado, legumes and citrus fruits, focusing on the buds, flowers and young leaves.
This, along with their habit of accidentally distributing fungal spores while feeding or hunting, makes them destructive crop pests. They tend to feed as a group in large numbers, causing distinctive silver or bronze scarring on the surfaces of stems or leaves.
However, not all thrips are harmful. A small fraction of the 6,500 species that have already been described so far are pollinators of flowering plants; and a handful are predators or natural enemies of moths and other smaller animals such as mites.
Tell us about the fossil thrips you’ve discovered
This is the first time that a fossil thrips has been recorded anywhere in Africa – or the entire southern hemisphere.
The Orapa Diamond Mine in Botswana is one of the most important fossil deposits on the continent. It’s about 90 million years old, dating back to the Cretaceous period.

The deposit is situated 960 metres above sea level in the Kalahari Desert, about 250km due west of Francistown in Botswana, and 824km away from Johannesburg in South Africa. It was first discovered in 1967 and started producing carat diamonds in 1971.
Roughly 90 million years go, steam and gas caused a double eruption of diamondiferous kimberlites. These are vertical, deep-source volcanic pipes that form when magma rapidly rises from the Earth’s mantle, carrying diamonds and other minerals up to the surface. They create a distinctive rock formation that gets studied by geologists. This explosive volcanic eruption formed a deep crater lake at the centre of the mine.
Mining excavations during the 1980s and earlier uncovered and exposed fine-grained sedimentary rocks containing well preserved fossil plants and insects. These have already been studied by many researchers in the past. At the time, geology and palaeontology researchers from what was then the Bernard Price Institute, which has since been renamed the Evolutionary Studies Institute, at the University of the Witwatersrand in Johannesburg, were invited to collect the fossil material.
Although some of the material has been studied in the past, the fossil thrips hadn’t yet been put under the microscope. And that’s just what we did. By using its body characteristics and comparing it to living thrips, we can say for sure that it’s a thrips. But we didn’t give it a formal scientific name because it doesn’t have enough characteristics to classify it at the species level and describe it either as a new species or one that still exists today.
We think that the thrips either flew into the palaeolake that was formed by the volcanic eruption or was transported there through grass from a bird’s nest.
Why is this useful to know?
This discovery sheds light on the biodiversity and biogeography of thrips and many other groups of insects during a time when we know flowering plants that heavily relied on insect pollination were rapidly diversifying. This plant-insect reciprocal interaction goes back to the Devonian period, a time when there was a large super-continent called Gondwana. That’s when the first land plants evolved and dominated the Earth, and inadvertently led to many groups of insects, including thrips, diversifying to keep up with drastic changes in their preferred plant diets and habitats due to the dramatic environmental and climatic changes.

The fossil find also contributes to a more accurate documentation of life on Earth during the Cretaceous and helps scientists in reconstructing the past environment and climate in Botswana.
Hopefully there are more fossil insects waiting to be discovered in Botswana and elsewhere in Africa, to keep improving our picture of this long-ago world, and preserve the heritage of our continent.

Africa: Expanding Market Access – Unlocking New Opportunities for Entrepreneurs

Published

on

7 Views

Sometimes, one opportunity is all it takes to change the trajectory of a business. For many women in the WCW Programme, 2024 has been a year of breakthroughs – where barriers gave way to bridges, and small businesses found space to grow.
Thanks to focused coaching and training, WCW entrepreneurs opened the door to over 10 new markets, generating opportunities valued at more than US$200,000. With tailored procurement support, they went even further – securing five supplier partnerships in Tanzania and seven in Zambia. These aren’t just numbers. They’re new deals signed, new shelves stocked, and new markets won.
Behind this progress is WCW’s strong belief in insight before action. Partnering with a leading service provider, the programme is helping entrepreneurs decode market trends, customer behaviours, and competitor landscapes. Through boot camps in six countries, women are now equipped with sharper strategies to position and promote their businesses like pros.
In the agriculture and agro-processing sectors, WCW is collecting critical data to pinpoint entry barriers, market concentrations, and competitive pressures. These insights are more than academic – they’re fuelling policy advocacy aimed at making it easier for small businesses to enter and thrive in high-potential sectors.
Support is also happening behind the scenes. WCW has brought in seasoned service providers to guide entrepreneurs in securing offtake agreements – particularly in agribusiness, where the potential to scale is massive. Plans to roll out a collective/aggregation model are also underway, giving smaller businesses the power to move together and tap into bigger supply chains.
Key Voices:
“The programme helped me focus on customer needs, allowing me to improve service delivery and expand my product range.”
— Participant from Tanzania
“The WCW-I programme has been helping me develop confidence, refine operations, and expand my market reach.”
— Participant from Zambia
With clearer pathways and stronger partnerships, WCW is showing what’s possible when entrepreneurs are given the tools – and the trust – to lead their own growth.

US to ban artificial food dyes in cereals, snacks and beverages

Published

7 Views

(BBC) US Health Secretary Robert F Kennedy Jr is set to announce a ban on certain artificial food dyes, according to a statement from the health agency.

Kennedy plans to announce the phasing out of petroleum-based synthetic dyes as a “major step forward in the Administration’s efforts to Make America Healthy Again” the US Department of Health and Human Services (HHS) said on Monday.

No exact dates for the changes were provided, but HHS said Kennedy would announce more details at a news conference on Tuesday.

The dyes – which are found in dozens of foods, including breakfast cereals, candy, snacks and beverages – have been linked to neurological problems in some children.

On the campaign trail alongside Donald Trump, Kennedy last year pledged to take on artificial food dyes as well as ultra-processed foods as a whole once confirmed to lead to top US health agency.

The move comes after the Food and Drug Administration (FDA) earlier this year banned one dye, Red Dye 3, from US food and pharmaceuticals starting in 2027, citing its link to cancer in animal studies. California banned the dye in 2023.

Most artificially coloured foods are made with synthetic petroleum-based chemicals, according to nutrition nonprofit Center for Science in the Public Interest (CSPI).

Some of the petroleum-based food dyes include Blue 1, used in candy and baked goods; Red 40, used in soda, candy, pastries and pet food; and Yellow 6, also used in baked goods and drinks. Synthetic food dyes are found in dozens of popular foods including M&M’s, Gatorade, Kool-Aid and Skittles.

The only purpose of the artificial food dyes is to “make food companies money”, said Dr Peter Lurie, a former FDA official and the president of CSPI.

“Food dyes help make ultra-processed foods more attractive, especially to children, often by masking the absence of a colorful ingredient, like fruit,” he said. “We don’t need synthetic dyes in the food supply, and no one will be harmed by their absence.”

Companies have found ways to eliminate many of the dyes in other countries, including Britain and New Zealand, said former New York University nutrition professor Marion Nestle.

For example, in Canada, Kellogg uses natural food dyes like carrot and watermelon juice to colour Froot Loops cereal, despite using artificial dyes in the US.

How harmful the synthetic dyes are is debatable, said Ms Nestle.

“They clearly cause behavioural problems for some – but by no means all – children, and are associated with cancer and other diseases in animal studies,” she said.

“Enough questions have been raised about their safety to justify getting rid of them, especially because it’s no big deal to do so,” she added. “Plenty of non-petroleum alternative dyes exist and are in use.”

In 2008, British health ministers agreed to phase out six artificial food colourings by 2009, while the European Union bans some colourings and requires warning labels on others.

In recent months, Kennedy’s food-dye ban has found momentum in several state legislatures. West Virginia banned synthetic dyes and preservatives in food last month, while similar bills have been introduced in other states.

Africa: Captain Ibrahim Traoré – the Soldier Selling Africa False Hope

Published

Traoré’s anti-democratic posture is not a blueprint for development — it is a calculated strategy to entrench military rule under the guise of a populist revolution.
What Traoré is selling is not a radical reimagining of governance. It is an age-old authoritarian tactic: discredit democracy, invoke national pride, and suppress dissent — all while consolidating power… Since assuming power through a 2022 coup, Traoré has suspended political parties, cracked down on the press, and muzzled civil society organisations. He claims these actions defend national sovereignty and promote a “popular, progressive revolution.”
Clad in fatigues and fluent in fiery rhetoric, Captain Ibrahim Traoré of Burkina Faso has emerged as a poster child of a new wave of African populism. To his supporters, he is a revolutionary — bold, youthful, and principled.
To the disillusioned youth across the continent, he offers a seductive promise: progress without the inconveniences of democracy. But behind the revolutionary slogans and Sankara-inspired aesthetics lies a far less romantic reality.
Traoré’s anti-democratic posture is not a blueprint for development — it is a calculated strategy to entrench military rule under the guise of a populist revolution. Let us be clear, Africa has every right to interrogate the forms and functions of democracy on the continent.
For decades, many African states have endured dysfunctional governance, hollow elections, and endemic corruption — even under democratically elected leaders. But that frustration must not be manipulated into legitimising authoritarianism.
What Traoré is selling is not a radical reimagining of governance. It is an age-old authoritarian tactic: discredit democracy, invoke national pride, and suppress dissent — all while consolidating power.
Since assuming power through a 2022 coup, Traoré has suspended political parties, cracked down on the press, and muzzled civil society organisations. He claims these actions defend national sovereignty and promote a “popular, progressive revolution.”
But there is little “popular” about a regime that stifles dissent and sidelines citizen participation. Beneath the rhetoric, his governance follows a familiar authoritarian script: glorify the military, delegitimise the opposition, and centralise authority.
His framing of democracy as a Western construct is both lazy and intellectually dishonest. Democracy is not a Western invention — it is a universal aspiration. It is not perfect — no system is — but it provides tools for accountability, the protection of rights, and peaceful transitions of power.
Traoré’s assertion that no country has developed under democracy ignores glaring counterexamples: India, Indonesia, Botswana, Mauritius, and even South Africa — imperfect democracies that have made tangible developmental progress.
Democracy is not the enemy of progress; bad leadership is. Traoré frequently cites China and Rwanda as models of authoritarian success. But cherry-picking these exceptions while ignoring the graveyard of failed autocracies is deeply misleading.
For every China, there are countless Zimbabwes, Sudans, and Libyas — nations brought to their knees by unchecked power. Even China’s economic gains have come at great human cost: widespread censorship, suppression of dissent, and the erosion of personal freedoms — trade-offs many Africans are neither willing nor ready to accept.
In truth, Traoré’s appeal is more symbolic than substantive. His military garb, rejection of Western aid, and Pan-Africanist slogans serve a performative function — designed to project the image of a revolutionary, while masking the repressive nature of his regime.
It is political theatre, expertly staged for a generation hungry for change but jaded by the failures of democracy. And let us not be fooled by his youth or populist flair. Africa has seen this movie before.
From Mobutu in Zaire to Mengistu in Ethiopia, the continent’s post-independence history is littered with military strongmen who promised renewal but delivered repression. They all began with charismatic appeals and revolutionary fervour.
They all ended with censorship, violence, and economic ruin. Traoré’s growing popularity among young Africans — many of whom have no memory of the brutality of past military regimes — is understandable, but dangerous.

Disillusionment with democracy should fuel reform, not nostalgia for dictatorship. Africa does not need another soldier-saviour. It needs strong institutions, functional systems, and an empowered citizenry — not one infantilised by authoritarian paternalism.
If Captain Traoré is genuinely committed to African sovereignty and development, let him invest in institution-building. Let him empower an independent judiciary, uphold press freedom, invest in civic education, and be accountable to the people — not just through speeches, but through action.
Anything less is not leadership — it is manipulation. The truth is, democracy does not fail because it is un-African. It fails when it is hijacked by corrupt elites, undermined by weak institutions, and eroded by poverty and exclusion.
The solution is not to discard democracy — but to fix it, to deepen it, to make it real. That is the only sustainable path to development, dignity, and self-determination.
