“…Results of the pathogenicity studies revealed the highest mortality (90%) at the concentration of 1 × 10 8 spores ml −1 and the lowest mortality (10%) at the concentration of 1 × 10 3 spores ml −1 with a LC 50 value of 5.8 × 10 4 spores ml −1 against 2nd instar FAW larvae. The efficacy of M. anisopliae against FAW was also reported by Gutiérrez-Cárdenas et al (2019) reported that the CP-MA 1 strain of M. anisopliae could cause 72.5% mortality at a spore concentration of 54 × 10 4 spores ml −1 . Akutse et al ( 2019) also observed that 1 × 10 8 conidia ml −1 of M. anisopliae strain ICIPE 41 could cause the highest mortality of 96.5% in FAW neonates.…”

Background The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) is a devastating pest of maize, difficult to manage using a single pest management tactic. The entomopathogenic fungus (EPF), Metarhizium anisopliae being an eco-friendly component, could be an effective tool for managing this notorious pest owing to its preferred habitat, principally the whorl region. Results Metarhizium anisopliae (TNAU-MA-GDU) isolated from FAW was evaluated against 2nd instar larvae of S. frugiperda reared under laboratory conditions. The pathogenicity and infection process were also studied through scanning electron microscope (SEM). The LC50 value for M. anisopliae isolate TNAU-MA-GDU was recorded as 5.8 × 104 spores ml−1 against the second instar larvae of S. frugiperda. SEM observations on the infection process revealed the adherence of the conidia on the head, cuticular ornamentations of the thorax, sensory seta, and legs at 24 h post-infection (hpi). Formation of germ tube and appressoria was observed from 48 hpi with subsequent hyphal development at 72 hpi. Complete networking of mycelium and conidiogenesis observed after 168 hpi. Conclusion An understanding of fungal–host interactions at the ultramicroscopic levels could reform present tactics for developing hyper-virulent EPF strains.

“…Current EPF products are focussed on formulations for foliar application against the immature life stages of FAW. However, the compatibility of EPFs with FAW pheromones and their impact on fertility and egg viability highlight the potential for the development of lure and infect application strategies (Rivero-Borja et al 2018;Gutiérrez-Cárdenas et al 2019;Akutse et al 2020b). Furthermore, endophytic colonization of cereals and other hosts with B. bassiana, M. anisopliae, and Metarhizium robertsii (Metchnikoff) Sorokin, and the impact of such plant colonization on FAW survival, growth, reproduction, and food preference offer a promising potential for incorporating EPFs into FAW management practices (Ramirez-Rodriguez & Sanchez-Pena 2016;Jaber & Ownley 2018;Vega 2018;Mwamburi 2021;Russo et al 2021;Gustianingtyas et al 2021).…”

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.

“…acridum . Thus, Gutiérrez-Cárdenas et al [ 164 ] disclosed the potential of entomopathogenic fungi for the management of adults of Spodoptera frugiperda using the auto-dissemination technique. Three isolates of Beauveria bassiana (Balsamo-Crivelli) Vuillemin and six isolates of Metarhizium anisopliae (Metschnikoff) (Hypocreales: Clavicipitaceae) were reported to be pathogenic to the insect, and the isolate M. anisopliae Ma-San Rafel-2 was used for auto-dissemination.…”

The fungus and the synthetic sex pheromone attracted, infected, and killed males 5–8 days after dissemination, paving the way for the potential management of S. frugiperda [ 164 ]. In the same way, Akutse et al [ 165 ] evaluated the effect of 22 entomopathogenic fungi isolates on the fall armyworm S. frugiperda , and their compatibility with the pheromone FALLTRACK lure.…”

Since the first identification of the silkworm moth sex pheromone in 1959, significant research has been reported on identifying and unravelling the sex pheromone mechanisms of hundreds of insect species. In the past two decades, the number of research studies on new insect pheromones, pheromone biosynthesis, mode of action, peripheral olfactory and neural mechanisms, and their practical applications in Integrated Pest Management has increased dramatically. An interdisciplinary approach that uses the advances and new techniques in analytical chemistry, chemical ecology, neurophysiology, genetics, and evolutionary and molecular biology has helped us to better understand the pheromone perception mechanisms and its practical application in agricultural pest management. In this review, we present the most recent developments in pheromone research and its application in the past two decades.
