“…Degri et al [59] studied the effect of intercropping pearl millet with groundnut on stem borer infestation of millet in Nigeria and found up to 48% reduction in the per cent of plants infested with stem borer and a 58% reduction in the number of borers per plant. This reduction was attributed to the increased levels of natural enemies found in the intercropped fields.…”

The fall armyworm (FAW) (Spodoptera frugiperda) is a crop pest species that has become global, having spread from its native American distribution to Africa and Asia since 2016. Its rapid spread, plus concerns about potential yield losses, have led to the search for sustainable management options. While most farmers affected by FAW in America have large-scale farm operations, the overwhelming majority of farmers in Africa and Asia are smallholders. This dramatically different context means that different management approaches must be sought. Large-scale producers with high-productivity, access to international market prices, risk-transfer mechanisms and the benefits of government subsidies are able to use technologies unavailable to smallholder farmers without access to those conditions. This review examines these differences and surveys the literature for accessible management options for smallholders, largely based on locally available solutions using ecological knowledge. Innovative digital solutions may also play a role in helping farmers learn about these solutions, and share them locally.

“…MSB pressure at Sadore during the study period was high, at the same level as that reported in 1996 both at this site with a MSB susceptible pearl millet cultivar (Drame-Yaye et al, 2003;Sastawa et al, 2002) and, for damage rate, as that reported from farmers' fields (on supposedly local pearl millet cultivars) in the Upper East Region of Ghana, and for MSB infestation, from the Upper West Region (Tanzubil and Mensah, 2000), and higher than the damage rate observed in 2010 to 2011 at Maiduguri in Northern Nigeria, with a MSB-susceptible pearl millet cultivar (Degri et al, 2014). Pearl millet cultivar Souna 3 infestation and damage by MSB observed in 2010 at Sadore were higher and more variable than those observed on the same site on cultivar ICMV 99001 (Ratnadass et al, 2014).…”

From 2008 to 2010, the effect of a wind erosion-alleviating practice, that is, planting of windbreaks of the perennial grass Andropogon gayanus Kunth on the populations of millet stem borer (MSB) Coniesta ignefusalis (Hampson) (Lepidoptera: Pyralidae) and the damage induced by this pest to pearl millet, was studied at Sadore (Niger). The extent of bored stems in the A. gayanus hedge bordering millet plots (23% on average) was significantly lower than in the millet plots (76% on average), with no MSB larva recovered, compared to an average of 2.2 larvae per stem in the millet plots over the three years. Andropogon grass was thus ruled out as a trap crop for MSB management. Under the conditions of this study, a pest regulation service by Andropogon grass hedges, synergistic with a potential wind erosion alleviating service, cannot be put forward.

“…Intercropping is commonly used in small‐scale farming systems for pest control as it diversifies crops in a given agro‐ecosystem to reduce the population of insects and consequently their attack (Degri, Mailafiya, & Mshelia, ; Pimental, Hepperly, Hanson, Douds, & Seidel, ; Vaiyapuri, Amanullah, Rajendran, & Sathyamoorthi, ). Studies in Kenya (Kinama, Habineza, & Jean Pierre, and references therein) and Egypt (Abdel‐Wahab, Abdel‐Wahab, & Abdel‐Wahab, ) demonstrated that cereal–legume intercropping has benefits beyond just pest and disease control, as they also measured increased yield, better biological nitrogen fixation, and better weed control.…”

Africa is burdened by food insecurity with nearly a billion people suffering from starvation, undernutrition, and malnutrition. Climate change prediction models forecast changes in rainfall patterns and rising temperature regimes, with impacts particularly on Southern and East Africa. These predictions are especially concerning for the production of major food crops, such as maize, sorghum, millet, and groundnut, because median temperature increases are associated with increased pest pressure and changes in migratory patterns. These factors will result in significantly more pest invasions and an increased need for innovative insect management practices. This review focuses on pest control strategies, highlighting important examples, their economic impact, and new alternative pest control strategies. African policymakers remain hesitant to move forward with establishing biosafety laws and commercializing GM crops, and it is often difficult to implement regulatory measures in smallholder agriculture to increase efficacy.
