Biocontrol reduces Maruca pod borer population by 85%
3 April 2020
Manuele Tamò, an insect ecologist and IITA’s Benin country representative, was excited about the results, adding that the next stage is to release the wasps in Niger and Nigeria.
The Maruca pod borer is a pest that attacks cowpea leading to devastating losses of up to 80%. Farmers have resorted to spraying 6‒8 times in a season, which is harmful to both human and environmental health. The use of this biocontrol measure is another successful intervention in plant health as IITA and partners spearhead the move towards sustainable food systems. In this video, Tamò explains more about this biocontrol method.
