Integrated pest management in Africa: the necessary foundation for insect resistance management

Tailoring IPM plans to fight a cloaked pest: helping smallholder farmers combat the sweetpotato weevil in sub-Saharan Africa

“…Concomitantly, the attention to SPW management could achieve improvements in both the quantity and quality of sweetpotato production. We also concur with others who have indicated that the inherent challenges which exist in SSA agriculture (Parsa et al 2014) might render it non-ideal to have the IPM plans in SSA (in this case for SPW) mimic programs from other developed countries (Oyediran 2023). Rather, we advocate the IPM plans which evolve for SSA should reflect the practice options that exist for a given locale and build off of more of a localized and coordinated approach to IPM awareness and implementation.…”

“…While some "success stories" have been demonstrated across various regions of Africa in the past when IPM has been practiced against other agricultural insect pest or disease problems (Kiss and Meerman 1991;Nwilene et al 2008;Norton et al 2019) problems exist in SSA which interfere with grower implementation of IPM. Of concern are aspects of IPM not being designed for current SSA considerations such as: a lack of cost-effectiveness, not being adaptable to farming practices that are in place, not being supported with requisite training and education, being presented with weak incentives for adoption, lacking the region-specific strong research association, and outreach challenges centered around limitations in the existing research and extension systems (Parsa et al 2014;Oyediran 2023). Oyediran (2023) has considered these IPM challenges for SSA in the context of other crop systems, however, those same problems noted likely interfere with IPM for sweetpotatoes as well.…”

Oyediran (2023) has considered these IPM challenges for SSA in the context of other crop systems, however, those same problems noted likely interfere with IPM for sweetpotatoes as well. For example, small scale farming and other aspects of routine sweetpotato farming practice(s) in SSA have been largely driven by local or even family subsistence economics as well as very individualized experience and training; it has not been primed to benefit from the consideration of new inputs and information regarding control options.…”

PRESENCIA DE DOS ESPECIES DE ÁCAROS (Prostigmata:Tetranychidae: Mononychellus) DE LA YUCA (Manihot esculenta Crantz), PROVINCIA DE COCLÉ, PANAMÁ

“…Entre otras afectaciones por el ataque de estos ácaros en la yuca, reportes en diversas localidades en África indican que las pérdidas secundarias incluyen la reducción de la superficie de las hojas, erosión, invasión de maleza y producción de una reducida calidad del material vegetativo destinado para la siembra de la siguiente temporada (Oyediran, 2023).…”
