Outbreaks of the fall armyworm (Spodeptera frugiperda), and maize production constraints in zambia with special emphasis on coping strategies

Abstract

The fall armyworm (FAW) (Spodoptera frugiperda J.E. Smith) is an invasive pest of maize, as well as other important cereals and vegetables, threatening food systems and biodiversity in Sub-Saharan Africa. This study aimed to assess the outbreaks of the FAW, farmers’ perceived production constraints, and coping strategies in maize production in Zambia. A participatory rural appraisal (PRA) study was conducted in two FAW-affected maize production districts in Zambia in 2017 and 2018. Data were collected using semi-structured questionnaires, preference ranking, and focused group discussions. Crop losses due to FAW, the high cost of fertilizers, and a limited availability of arable land were the major production constraints across the districts. There were significant differences (X2 = 12.415; p = 0.002) in the severity of FAW infestation between the two districts in 2017. Notable FAW coping strategies used by the respondent farmers included cultural and landscape management practices, chemical pesticides, and crushing of FAW larvae. There was a disparity between male and female respondents who perceived social, agronomic management, and crop protection-related factors that influenced the choice of a maize variety. Information presented here will serve as a basis for FAW-resistant cultivar development and deployment of the integrated pest management methods for Zambia.
