An insecticide based on fungal spores is devastating locusts in a trial in Mauritania, says a report from Reuters. The spores — dubbed Green Muscle — come from a species called Metarhizium anisopliae, whose locusticidal properties have been known since 1989. Green Muscle’s proponents have been waiting since 1998 for an opportunity to test it in the field, but have been thwarted by a lack of gregarious locusts.
The test showed that Green Muscle works well, with an added bonus that the weakened young locusts are a magnet for predators of all kinds, who despatch them even before the fungus has done its work. The treatment was developed by scientists at the International Institute of Tropical Agriculture and the good folks at FAO have said that if the Mauritania test is a success they will adopt it for widespread use in Africa.
