“…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 ). It caused enormous damage in Africa on sorghum (Hailu et al 2021 ) and maize crops, with an annual loss in yield up to 17.7 million tons (Day et al 2018 ; International Plan Biotechnology Outreach (VIB) 2019 ; Kassie et al 2020 ).…”

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.

“…Spodoptera frugiperda Data in Table (1) showed the toxicity of tested chemical insecticides, Flubendiamide, lambada cyhalothrin against 4 th instar larvae of fall armyworm (FAW) S. frugiperda when applied with immersion technique method. Insecticides were rapid and highly toxic, then EPNs in which compounds gave effects to calculate their LC 50 values after 24 hours and were (3.26± 0.52 and 04.23±0.85) for flubendiamide and lambada cyhalothrin, respectively without a large variation among LC 50 values among the two insecticides.…”

Under laboratory conditions, the activity of two entomopathogenic nematodes, Heterorhabditis bacteriophora (HP88) and Steinernema carpocapsae (AT4), as well as their compatibility with two common insecticide formulations (lambada cyhalothrin and flubendiamide) and one insect growth regulator (lufenuron), were evaluated against Spodoptera frugiperda. The nematode IJs were subjected to the LC 50 and LC 25 of insecticides, and the viability of infective juveniles (IJs) was measured before being tested against Galleria mellonella larvae to determine IJs pathogenicity. Also, the mixtures were evaluated against the 4 th instar larvae of S. frugiperda to select one mixture can serve in integrated pest management (IPM) in agro-ecosystems. Results showed that H. bacteriophora strain (HP88) was more efficient with higher pathogenicity and virulence against 4 th larvae of S. frugiperda (LC 50 = 48.67±0.34IJs/ml -1 ) than S. carpocapsae (AT4) (LC 50 = 65.88± 3.04). flubendiamidee was the most toxic insecticide (LC 50 = 3.26±0.52) followed by Lambada cyhalothrin (4.23±0.8PPM). Lufenuron was the least toxic one (5.67±1.53PPM). Both EPN H. bacteriophora (HP88) and S. carpocapsae viability was not affected by any of tested insecticides (LC 25 and LC 50 ), while lambada cyhalothrin reduced S. carpocapsae pathogenicity with LC 50 concentration. Lufenuron at the rate LC50 and Lc25, not affect H. bacteriophora and S. carpocapsae pathogenicity. All tested insecticides with the two doses were harmless according to IOBC test. All mixtures of insecticides with the two EPN strains were synergistic effect against 4 th larvae of S frugiperda except lufeuron with LC 25 was antagonist. It was explored how these nematode insecticide combinations could be used in maize pest management.

“…Fall Armyworm (FAW), Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae), is one of the deadliest insect pests for economic crops, having arrived to Egypt from South African countries, attacking over 353 plant species (Casmuz et al, 2010;Rwomushana, 2019 andMontezano et al, 2018). S. frugiperda was first discovered in Egypt in a corn field at Kom Ombo, Aswan Governorate, Upper Egypt, in May 2019 (Dahi et al, 2020;Mohamed et al, 2022). The larvae of S. frugiperda is the damaging stage, with caterpillars feeding on young leaf whorls, ears, and tassels, producing significant damage to maize crops and severe grain yield loss (Sarmento et al, 2002;Rwomushana et al, 2017 andPrasanna et al, 2018).…”

Y MAY of 2019, it was the first time to report fall armyworm, Spodoptera frugiperda (Smith) at Upper Egypt. So, two field experiments were conducted at Nubaria region, Behaira Governorate to find out the relationship between population of S. frugiperda larvae and maize grain yield, and to assess yield loss%, voltinism (annual number of generation) and to evaluate the economics of maize production under the circumstances of some insecticidal applications. The RCBD with four replicates was used and treatments included two insecticides (methomyl and emamectin benzoate) applied in trinary or binary sequences against fall armyworm. There was a negative correlation between population of S. frugiperda larvae and maize grain yield. Applying methomyl and emamectin benzoate in a trinary sequence produced the highest maize yield; 4.249 and 3.416 t/fed in the 1 st and 2 nd seasons, respectively. The highest quantitative yield losses were found in untreated check plots;77.76 and 78.89% in 1 st and 2 nd seasons, respectively. Methomyl, emamectin benzoate and methomyl sequence produced the highest net benefit over untreated check and net benefit/ total costs (%).The insect pest had 5 generations on maize plants during the growth period from May1 st to November 30 th in both seasons. To avoid the widespread off all armyworm, in Egypt, the growers are recommended to spray a sequence of insecticides, including methomyl 15 days after planting, emamectin benzoate, and methomyl at recommended doses with 10 day-interval between each two pesticide applications.
