Discussion

Fieldwork demonstrates reduced insect incidence in millet when combined with cowpea and biopesticides, suggesting improved yields.

Cowpea intercropping reduced the incidence of Heliocheilus albipunctella, indicating an effective pest management strategy.
Fieldwork conducted in Burkina Faso's Djibasso and Dori communes found a significant yield increase by over 40%.
The integration of biopesticides, specifically neem extracts, was shown to be beneficial at the flowering stage of cowpea.
This approach may provide a sustainable alternative to synthetic insecticides, thereby promoting environmental health.

Boly et al. (2025) studied this question.
