“…Biological control, particularly using parasitoids as primary agents, combined with other control measures, has been shown to reduce costs, minimize agricultural nonpoint source pollution, and achieve long-term and effective control [23]. Several studies demonstrated that parasitic wasps can limit the population growth of S. frugiperda to some extent [24,25]. The parasitoid species Cotesia ruficrus (Hymenoptera: Braconidae) is an endoparasitic wasp that can parasitize the larvae of several pests in Noctuidae and Pyralidae families [26,27].…”

Chemosensory proteins (CSPs) are a class of soluble proteins that facilitate the recognition of chemical signals in insects. While CSP genes have been identified in many insect species, studies investigating their function remain limited. Cotesia ruficrus (Hymenoptera: Braconidae) holds promise as an indigenous biological control agent for managing the invasive pest Spodoptera frugiperda (Lepidoptera: Noctuidae) in China. This study aimed to shed light on the gene expression, ligand binding, and molecular docking of CrufCSP1 in C. ruficrus. A RT-qPCR analysis revealed that the expression of CrufCSP1 was higher in the wings, with male adults exhibiting significantly higher relative expression levels than other developmental stages. A fluorescence competitive binding analysis further demonstrated that CrufCSP1 has a high binding ability with several host-related volatiles, with trans-2-hexenal, octanal, and benzaldehyde showing the strongest affinity to CrufCSP1. A molecular docking analysis indicated that specific amino acid residues (Phe24, Asp25, Thr53, and Lys81) of CrufCSP1 can bind to these specific ligands. Together, these findings suggest that CrufCSP1 may play a crucial role in the process of C. ruficrus locating hosts. This knowledge can contribute to the development of more efficient and eco-friendly strategies for protecting crops and managing pests.

“…Interactions with other insects, such as competing herbivores and natural enemies, affect fall armyworm performance (Costa et al, 2022). In its native region, fall armyworm is a host to a large variety of parasitoid wasps and flies (von Mérey et al, 2012; Barreto‐Barriga et al, 2021; Traine et al, 2021), some of which are commercially available (Vargas et al, 2021). The species is also frequently attacked by predators, fungi, viruses, and entomopathogenic nemathodes (Molina‐Ochoa et al, 2003; Fallet et al, 2022).…”

Fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a voracious pest of various crops, such as maize, rice, and sugarcane. Originally from the tropical and subtropical regions of the Americas, it recently spread around the world. As populations can be resistant to pesticides, integrated pest management (IPM) is important, relying on a combination of chemical, physical, and biological control. This special issue of Entomologia Experimentalis et Applicata includes both fundamental and applied studies on fall armyworm biology, monitoring, and control, setting the stage for the development of effective, sustainable strategies to protect crops against fall armyworm, both in its native range and in areas where it has invaded.

“…The type and size of a study arena used to assess predation can influence the results obtained from the experiments, with predation rates usually decreasing from small, closed containers to open containers to plants within cages (Macfadyen et al 2015). The placement of prey can influence predation results in artificial arenas, because predator searching behavior and efficiency may change on different plant parts and species (Coll et al 1997;Castellanos et al 2010;Barreto-Barriga et al 2021). Food deprivation also can influence rates of predatory attacks, and in ambush predators the attack distance increases with hunger (Wallin & Ekbom 1994;Taylor & Schmidt 1996).…”
