    Experiences and Perspectives on Spodoptera frugiperda (Lepidoptera: Noctuidae) Management in Sub-Saharan Africa
    (Journal of Integrated Pest Management, 2021) Njuguna, Elizabeth; Nethononda, Phophi; Maredia, Karim; Mbabazi, Ruth; Kachapulula, Paul; Rowe, Arielle; Ndolo, Dennis
    It has been over five years since the first report of an outbreak of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) in Africa. The highly invasive pest, native to the Americas, has since spread across the African continent attacking many crops and causing significant yield loss to Africa’s staple crop, maize. From the onset of the outbreak, there have been massive and varied responses from farmers, governments and nongovernmental organizations. This mini-review provides various perspectives on S. frugiperda control in sub- Saharan Africa, building on previously published evidence, and experiences of the authors. It also highlights new technologies and lessons learned so far from the S. frugiperda outbreaks in sub-Saharan Africa, based on which suggestions on possible integrated management approaches are proffered.

    Research and Development of Biopesticides: Challenges and Prospects
    (Outlooks on Pest Management, 2019) Ndolo, Dennis; Njuguna, Elizabeth; Oluwaseun Adetunji, Charles; Harbor, Chioma; Rowe, Arielle; Breeyen, Alana Den; Sangeetha, Jeyabalan; Singh, Gurpreet; Szewczyk, Boguslaw; Anjorin, Toba S.; Thangadurai, Devarajan; Hospet, Ravichandra
    Even though pesticides have greatly contributed to boosting agricultural productivity and farmer income over the years, there have been concerns about the safety of some of these pest control products. Besides, there has been a growing demand for good quality and safe food in the recent past – as reflected in the stringent regulations on pesticide residue levels in produce (Damalas & Koutrobas, 2018). Biopesticides in comparison with conventional synthetic chemical pesticides are usually less toxic, generally affect only the target pest and closely related organisms, are often effective in relatively small quantities and decompose faster, resulting in lower exposure. Consequently, over the last few years, biopesticides have attracted global attention as a safer pest control strategy (Arora et al., 2016) for incorporation into Integrated Pest Management (IPM) programmes. Besides, in the last decade, adoption of IPM programmes has significantly enhanced pest management practices and, in some cases, reduced pesticide use, consequently reducing the rise in demand for synthetic chemical pesticides.
