“…However, the choice of a parasitoid is influenced by several factors, among which is its foraging behaviour. 35 In that regard, it is important to assess the foraging behaviour of parasitoids, which include investigation of parasitoid behaviour in location of the host and/or habitat with potential patches of suitable host species, host acceptance for oviposition, preference for different host species, sex allocation and number of offspring, 36 among others. Nevertheless, the foraging behaviour of a parasitoid is influenced by the complexity and diversity of the insect community within an ecosystem.…”

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.
