Eat them, poison them and use scent to drive them to cannibalism – as a second wave of locusts threatens to devour East Africa's crops, scientists in a Nairobi lab are experimenting with novel ways to kill them.
Swarms are the worst for three generations, encouraged by unseasonably wet weather and dispersed by a record number of cyclones. The destructive pests could cost East Africa and Yemen $8.5 billion (Dh 31.2) this year, the World Bank has said.
Locusts are usually controlled by spraying them with pesticides before they can fly, but the chemicals can damage other insects and the environment.
So, scientists at the International Centre of Insect Physiology and Ecology (ICIPE) are experimenting with biopesticides and the use of locusts as human and animal food as they look for environmentally-friendly extermination methods.
ICIPE researchers were a part of a group that discovered an isolate from a fungus, Metharizium Acridum, could kill locusts without harming other creatures. The isolate is now being used across East Africa.
Now researchers are pouring through 500 other fungi and microbes in their bio bank in the hope of discovering another locust poison.
ICIPE scientist Baldwyn Torto's research has mostly focused on locust smells and pheromones.
Before locusts can fly, they have a certain chemistry and therefore a unique smell that allows them to remain in a group, he said. That smell changes as locusts mature.
Disseminating the scent of an adult among the young can help destroy swarms.
"They get disoriented, the group breaks into pieces, they cannibalize each other and they become even more susceptible to biopesticides," he said.
A lower-tech, but still environmentally-friendly way of combating locusts is eating them.
ICIPE is developing nets and backpack-vacuums to capture large numbers of locusts. The protein-rich insects can then be cooked or crushed into meal or oil suitable for animal feed or human consumption. ICIPE organizes regular events to normalise the consumption of insects.
Researcher Chrysantus Tanga eats the insects himself. In the ICIPE cafe, the heads, legs and wings have been removed.
"They have to make it presentable for a first-timer," Mr Tanga said motioning towards colourful plates of locust-based meals prepared by ICIPE chefs, ranging from deep-fried with tartar sauce, to skewered among vegetables in a kebab.
"For me, I'll eat 100 per cent of it... whatever is crunchy."

Stormy seas
Weather warnings show that Storm Eunice is soon to make landfall. The videographer and I are scrambling to return to the other side of the Channel before it does. As we race to the port of Calais, I see miles of wire fencing topped with barbed wire all around it, a silent ‘Keep Out’ sign for those who, unlike us, aren’t lucky enough to have the right to move freely and safely across borders.
We set sail on a giant ferry whose length dwarfs the dinghies migrants use by nearly a 100 times. Despite the windy rain lashing at the portholes, we arrive safely in Dover; grateful but acutely aware of the miserable conditions the people we’ve left behind are in and of the privilege of choice.
