“…Given pesticide resistance, many of these insecticides are often ineffective [ 188 ]. Furthermore, resource-poor farmers in developing countries usually cannot afford personal protective equipment and lack the knowledge and understanding of chemical pesticides and their safe use [ 46 ], which compromises their proper use and risks exposure to toxic substances, resulting in accidental poisonings. Widespread and indiscriminate use of chemical pesticides also undermine environmental quality (biodiversity loss and pollution of air and water) and the pest control services provided by natural enemies [ 208 ].…”

“…The use of synthetic pesticides to control both field and storage insect pests is dominant in Africa [ 240 ]. Regarding S. frugiperda , control is maintained mainly through the use of a combination of synthetic pesticides and cultural (early planting, varietal selection and field hygiene) and mechanical methods [ 40 , 46 , 113 ]. Since the invasion of the African continent by S. frugiperda , huge quantities of pesticides amounting to trillions of US dollars have been used to control the pest ([ 241 ]; Table 2 ).…”

“…Since the invasion of the African continent by S. frugiperda , huge quantities of pesticides amounting to trillions of US dollars have been used to control the pest ([ 241 ]; Table 2 ). However, the use of synthetic pesticides is unsustainable due to high costs, resistance development, pest resurgence and negative effects to environmental and human health [ 40 , 46 ]. This calls for the development and use of alternative control options, for example, systemic seed treatments [ 242 ].…”

“…This polyphagous characteristic enables the pest to survive across diverse host environments. Spodoptera frugiperda larvae defoliate crops during vegetative growth reducing crop growth and reproductive capacity [ 10 , 42 , 43 , 44 , 45 , 46 , 47 ]. In maize, the pest attacks the crop up to the soft dough stage, increasing the crop’s vulnerability to additive losses through storage insects and mycotoxin contamination [ 45 ].…”

Invasive alien species (IAS) are a major biosecurity threat affecting globalisation and the international trade of agricultural products and natural ecosystems. In recent decades, for example, field crop and postharvest grain insect pests have independently accounted for a significant decline in food quantity and quality. Nevertheless, how their interaction and cumulative effects along the ever-evolving field production to postharvest continuum contribute towards food insecurity remain scant in the literature. To address this within the context of Africa, we focus on the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), and the larger grain borer, Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae), two of the most important field and postharvest IAS, respectively, that have invaded Africa. Both insect pests have shown high invasion success, managing to establish themselves in >50% of the African continent within a decade post-introduction. The successive and summative nature of field and postharvest damage by invasive insect pests on the same crop along its value chain results in exacerbated food losses. This systematic review assesses the drivers, impacts and management of the fall armyworm and larger grain borer and their effects on food systems in Africa. Interrogating these issues is important in early warning systems, holistic management of IAS, maintenance of integral food systems in Africa and the development of effective management strategies.

“…Within the IPM approach, several strategies such as early monitoring, cultural practices, physical control and biological control have been employed for management of S. frugiperda. [19][20][21] Biological control using parasitoids represents a good option for management of invasive pests. This approach involves three strategies: classical, augmentative and conservation biocontrol.…”

BACKGROUNDMaize production in Africa is hindered by a myriad of biotic challenges, key among them being invasive and native lepidopteran stemborers. Recent invasion of the continent by fall armyworm, Spodoptera frugiperda, has further exacerbated the situation. Fortunately, Cotesia icipe was found to be very promising against S. frugiperda. However, the co‐occurrence and interaction between S. frugiperda and the stemborers (Busseola fusca, Sesamia calamistis, and Chilo partellus) in maize agroecosystem may jeopardize the efficiency of C. icipe as a biocontrol agent of S. frugiperda. This study investigated the performance of C. icipe on S. frugiperda, Spodoptera littoralis and the stemborers. Specifically, the preference and acceptability of C. icipe to the host insects, the physiological suitability of the hosts for its development, and the effect of these hosts on the fitness parameters of the offspring were assessed.RESULTSCotesia icipe accepted all the tested hosts, albeit with higher preference for Spodoptera species than for stemborers under multiple‐choice tests. Also, the highest parasitism of up to 97% was recorded on S. frugiperda compared with parasitism on the stemborers of 43% in B. fusca. Moreover, physiological suitability and fitness traits (except for per cent female offspring) varied with host species, again being optimal on Spodoptera species.CONCLUSIONCotesia icipe demonstrated strong potential to control S. frugiperda in maize due to its high affinity for parasitization and developmental success in this host; and despite its non‐specific parasitization, the presence of other hosts may not prevent its maximum control of S. frugiperda. © 2023 The Authors.
