“…Results indicated that maize leaves could be considered as a more favorable food material to rearing of S. frugiperda. These results agree with findings by Gamil 2020, Guo et al, 2021and Maha et al, 2024 Also, artificial diet can be considered a suitable food source to S. frugiperda larvae as it, successfully, complete their life on it and succeeded in laying fertile eggs (87.38% hatchability). It can also be arranged favorable food material to rearing of S. frugiperda, as follows: maize, artificial diet, rice, pea and tomato.…”

Spodoptera frugiperda (J.E.Smith) (fall armyworm), is very serious pest in Americas and has newly be an invasive pest in Africa. Exhaustive register of S. frugiperda's plant of hosts is major to better understand the biology of this pest and develop Integrated Pest Management programmes. Impact of various plant of hosts on food consumption,host preference and several biological side,determine total protein,carbohydrate and lipid for third instar larvae of S. frugiperda were executed on laboratory. Outcome indicated that, larvae fed on leaves of maize, rice and artificial diets had the fastest larval and pupal development cycle. While those fed on pea and tomato had the longest one. In case of moth emerging from larvae fed on maize showed longest life span. But moths producing from larvae fed on leaves of tomato had the shortest life span. Obtained results revealed that, female moths produced from larvae fed on maize, rice and artificial diet laid the highest number of eggs,but female producing from larvae fed on tomato leaves produced the least number of eggs. Otherwise,the highest mean larval consumption for maize and wheat. While,larvae fed on leaves of tomato showed lowest mean consumption. Results reported that, total protein,carbohydrate and lipid were higher in the haemolymph of 3 rd instar larvae of S. frugiperda reared on maize, wheat and rice leaves. Meanwhile, tomato and cucumber were present at a low value level. Studies showed that,maize was the preferred host for S. frugiperda,but may be also,successfully reared on another plants especially in absence of the main host.

“…The fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is one of the major invasive polyphagous pests that habitat more than 353 plant species, especially maize, sorghum, sugarcane, turfgrass, cotton, and vegetable crops (Montezano 2018 ; Gamil 2020 ; Timilsena et al 2022 ). Since 2016, S. frugiperda has spread rapidly over 44 countries in West Africa (Day et al 2018 ; Kassie et al 2020 ).…”

“…Since 2016, S. frugiperda has spread rapidly over 44 countries in West Africa (Day et al 2018 ; Kassie et al 2020 ). In Egypt, S. frugiperda was first recorded on maize fields in 2019 in Komombo, Aswan Governorate (Food and Agriculture Organization (FAO) 2019 ; Dahi et al 2020 , Gamil 2020 ). Thereafter, it overspread Upper Egypt governorate towards the north on maize and sorghum crops in 2021 (Mohamed et al 2022 ).…”

Frequent inspections on sorghum and maize crops during seasons of 2021 and 2022 in some regions in Bani-Suef governorate, Egypt, discovered unprecedented invasions of Spodoptera frugiperda (J. E. Smith). Accordingly, our study on Beauveria bassiana and spinetoram was supporter to the Food and Agriculture Organization’s tendency in adopting biorational insecticides against S. frugiperda in Egypt. Exposure toxicity of LC25 values at 48 h of B. bassiana were 2.7 × 106 and 5.2 × 106 conidia mL−1 and spinetoram were 0.019 and 0.048 mg L−1 against the 2nd and 4th instar larvae laboratory strain of S. frugiperda, respectively. Sub-lethal effects (LC25) were accomplished on biological parameters against both instar larvae. LC25 of B. bassiana reduced adult emergency (89.91 and 91.05%) more than spinetoram (75.99 and 79.49%) against the 2nd and 4th instar larvae, respectively. The 2nd instar larvae exposed to LC25 of B. bassiana suppressed female fecundity (0.00 eggs) more than spinetoram (19.74 eggs). Enzymatic activity of lipase in hemolymph, fat bodies, and mid-gut of the 4th instars at 48 h showed significant drop in B. bassiana more than spinetoram. Glutathione-S-transferase (GST) levels in hemolymph for both insecticides were equal and exceeded the control. Fat bodies and mid-gut possessed the highest GST activity in B. bassiana followed by spinetoram and the control. Residual efficacy of spinetoram exceled B. bassiana at their field rates under semi-field condition in Bani-Suef along the two seasons of maize crop against both instars. Eventually, B. bassiana alongside spinetoram could afford good control especially on early instar larvae of S. frugiperda.

“…The invasion process typically occurs in three distinct phases [31]. First, it involves the introduction of a non-native species to an area outside of its original habitat, often facilitated by human activities such as trade, urbanization, and infrastructure development [32]. The second phase entails the establishment of stable populations, supported by either a higher intrinsic growth rate [33] or superior competitive ability compared to native species [34].…”

Fall armyworm, Spodoptera frugiperda, is a serious agricultural pest native to tropical and subtropical regions of the Western Hemisphere and has invaded Africa and further spread into most countries of Asia within two years. In Egypt, researchers have conducted thorough investigations into the behavior of the fall armyworm and various methods to manage its impact. This study aims to further our understanding of the genetic diversity of fall armyworm populations in Egypt. By collecting specimens from five provinces across the country, we sought to analyze their genetic makeup. Through examination of partial sequences of the mitochondrial cytochrome oxidase subunit I (COI), we identified three distinct haplotypes. Phylogenetic analysis suggests that the primary sources of Spodoptera frugiperda in Egypt likely stem from both Asian and African origins. Employing the PCR-RFLP technique on the complete COI sequence, we were able to discern genotype patterns within the fall armyworm population. Our findings indicate the presence of two distinct strains—the Corn and Rice strains—within Egypt. This research contributes essential insights into the genetic diversity of insects in Egypt, providing valuable knowledge that can inform more effective strategies for managing this agricultural pest.
