Résumé

Spodoptera frugiperda, the fall armyworm (FAW), has become a major pest of maize since its
appearance in Burkina Faso in 2017 requiring appropriate emergency response. A survey was
conducted with 161 maize farmers from 9 regions and 48 villages in the Sudano-Sahelian and Sudanese
agro-climatic zones, the main maize-growing areas in Burkina Faso to collect their perceptions. For this
purpose, a questionnaire designed on the Open Data Kit (ODK) mobile platform was administered to
them individually. 96% of the farmers considered FAW the main current biotic constraint to maize
cultivation. Most of them (98%) declared they could recognize the pest even though 60% had not
received any training on the pest identification. Production losses caused by FAW range from 25 to 50%
each year for 91% of the respondents. More farmers (90%) systematically use chemicals, notably
Emacot 50WG (Emamectin benzoate 50 g/kg) against the pest. Unfortunately, 96% of users do not take
any appropriate personal protective measures, while more than half (59%) have experienced adverse
health effects. These results contribute to the implementation of a better FAW control strategy. It is also
recommended that an effective national surveillance and early warning system be set up to better
manage other such pests.
