However, Allen et al (2021) argue that larval parasitism rates are probably largely underestimated in most studies in the Americas because of likely biases in sampling and calculation of parasitism rates. Furthermore, the extensive use of pesticides and Bt crops probably negatively affects natural parasitism rates, either by direct effect on parasitoids or because many parasitoids forage in a density-dependant manner (Ramirez-Romero et al 2007;Desneux et al 2010;Han et al 2016).…”

“…The recent worldwide invasion of FAW in Africa and Asia has generated interest for CBC using natural enemies from the Americas (Allen et al 2021;Tepa-Yotto et al 2021). However, nowadays, selecting a CBC agent for introduction into a new area is a long process involving careful assessments of potential non-target effects (Hayek et al 2016).…”

“…Among the main parasitoids of FAW, few appear specific. Eiphosoma laphygmae is one of them and is presently being evaluated for potential introduction in Africa and Asia (Allen et al 2021). The most abundant and widely distributed parasitoid of FAW in its native range, C. insularis, is also known from a few other hosts (Yu et a.…”

The fall armyworm (FAW), Spodoptera frugiperda (JE Smith, 1797), is a serious pest of several crops, particularly maize and other cereals. It has long been known as a pest in the Americas and has invaded most of Africa and parts of the Middle East, Asia, and Australia in the last six years. Its new status as an invasive species causing serious damage in many regions worldwide has highlighted the need for better understanding and has generated much research. In this article, we provide a comprehensive review of FAW covering its (i) taxonomy, biology, ecology, genomics, and microbiome, (ii) worldwide status and geographic spread, (iii) potential for geographic expansion and quarantine measures in place, and (iv) management including monitoring, sampling, forecasting, biological control, biopesticides, agroecological strategies, chemical control, insecticide resistance, effects of insecticides on natural enemies, as well as conventional and transgenic resistant cultivars. We conclude with recommendations for research to enhance the sustainable management of FAW in invaded regions.

“…In Florida, Meagher et al (2016) studied parasitism of S. frugiperda in sweet corn and found that larval parasitism rates were much higher in unsprayed fields (average 44%, up to 91% in some fields) than in fields sprayed with insecticides (15%). The low rates of parasitism mentioned in the literature may also result from underestimations due to sampling and calculation methods ( Vickery 1929 , Allen et al 2021 ). Most studies on field parasitism of S. frugiperda do not separate between larval instars.…”

Fall armyworm, Spodoptera frugiperda (J.E. Smith) is a polyphagous agricultural pest threatening food security worldwide. This American species recently invaded most of Africa, many Asian countries, and Oceania, where it mainly damages maize. Classical biological control (CBC) through the introduction of natural enemies from its area of origin is considered as a potential management approach. The paper reviews the prospects and constraints of a CBC programme against S. frugiperda using larval parasitoids, which are considered the most suitable natural enemies for introduction against this pest. The most important larval parasitoids in its native range are presented and discussed for their suitability as CBC agents, based the following criteria: their frequency of occurrence and parasitism levels, specificity, climatic suitability and absence of closely related species parasitizing S. frugiperda in the area of introduction. The ichneumonid Eiphosoma laphygmae Costa-Lima (Hymenoptera: Icheumonidae) is considered as a potential candidate for introduction because of its specificity and its importance as a parasitoid of the pest in most of its native range. The most frequent and important parasitoid of S. frugiperda in the Americas, the braconid Chelonus insularis Cresson (Hymenoptera: Braconidae), would most probably contribute to the control of S. frugiperda if released in invaded areas. However, it is oligophagous and would most certainly parasitize nontarget species. Before introducing C. insularis, or any other parasitoid species, the potential nontarget effects will have to be assessed and the risks will have to be weighed against the benefits of improving the natural control of this important pest.

“…Classical biological control, i.e., the introduction of parasitoids from the native range of the pest, is considered in several invaded regions ( Allen et al 2021 ). Should Europe be seriously invaded by S. frugiperda in the future, classical biological control could be envisaged, considering first the most cold-tolerant and most specific, thus safe, American parasitoids.…”

We here review and discuss management options that growers in Europe could take in response to the expected invasion of the fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae). The focus is put on maize but the information provided is also relevant for other crops potentially affected. A sound forecasting system for fall armyworm both on a regional as well as at local scale should be established to alert growers as early as possible. Whilst a number of cultural control methods are adopted by maize growers in different regions globally to fight fall armyworm, many of them may either not be highly effective, too laborious, or otherwise unfeasible within the mechanized crop production systems used in Europe. Potential is seen in the stimulation of natural enemies through conservation biocontrol approaches, e.g., the planting of flower strips or intermediate cover crops, reducing tillage intensity, and avoiding broad-spectrum insecticides. To manage fall armyworm infestations, several effective biologically-based products are available globally, and some in Europe, e.g., based on specific baculoviruses, certain Bacillus thuringiensis strains, few entomopathogenic nematodes, and a number of botanicals. These should be given priority to avoid a major influx of insecticides into the maize agro-ecosystem once the fall armyworm arrives and in case growers are not prepared. Plant protection companies, particularly biocontrol companies should act proactively in starting registration of ingredients and products against fall armyworm in Europe. European maize growers should be made aware, in time, of key features of this new invasive pest and appropriate control options.
