The fall armyworm (FAW), Spodoptera frugiperda, is one of the most important invasive pests worldwide, resulting in considerable losses host crops. FAW comprises two genetic strains, such as “rice strain”, which prefers rice and other grass species, “maize feeds upon maize sorghum. Potential control measures are generally more applicable to farmers who lack financial assets buy chemical insecticides or costly pure seeds. adverse effects pesticides on ecosystem human’s health development resistance insect have exaggerated efforts find an alternative strategy that cost-effective, low-risk target-specific. Therefore, biological widely considered options for pest management. This comprehensive review amasses information all phases their development, including predators, parasitoids, entomopathogenic fungi, viruses, nematodes, bacteria, biopesticides, with a special focus effectiveness against FAW. findings regarding briefly discussed light improving management programs S. frugiperda.

The chemical application is considered one of the most crucial methods for controlling insect pests, especially in intensive farming practices. Owing to application, pests are exposed toxic insecticides along with other stress factors environment. Insects require energy and resources survival adaptation cope these conditions. Also, insects use behavioral, physiological, genetic mechanisms combat stressors, like new environments, which may include chemicals insecticides. Sometimes, continuous selection pressure metabolically costly, leads resistance development through constitutive upregulation detoxification genes and/or target-site mutations. These actions costly can potentially affect biological traits, including reproduction parameters key variables that ultimately overall fitness insects. This review synthesizes published in-depth information on costs induced by insecticide past decade. It thereby highlights resistant populations might help design integrated pest management (IPM) programs spread populations.

The use of excessive chemicals in agriculture can cause harm to the environment and human health. Sustainable systems promote agroecological practices reduce chemical environmental However, there is a lack data on status adoption Fez-Meknes region, which significant national vegetable production area. To address this gap, we conducted cross-sectional surveys with 603 farmers analyze their practices, behaviors, knowledge regarding bio-product use, as well risks crops, health, environment. Additionally, aimed diagnose diffusion identify most relevant obstacles motivations for adoption. Our results indicate that majority (95%) throughout process but good understanding associated risks. do have access alternative such crop rotation (99.67%), manure (96.35%), drip irrigation (74.46%), intercropping (69%). success these among was motivation (50%), whereas difficulties managing pests diseases without pesticides (73.2%) technical advice support (70.8%) were main barriers In conclusion, our study highlights need training financial encouragement from state healthy eco-friendly farming practices.

Abstract Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) has significantly affected maize crop yields, production efficiency, and farmers’ incomes in the Indian Eastern Gangetic Plains region since it was first observed India 2018. A lack of awareness by growers appropriate selection, method, timing insecticide application not only creates a barrier to sustainable FAW control but also contributes increased environmental pollution, reduced human health costs. We demonstrated that inflicted most damage early whorl growth stage maize, regardless whether chemical insecticides were applied. egg masses larvae collected from fields which no had been sprayed showed high parasitism rates parasitoid wasps; contrast much lower on FAW. Ten hymenopteran parasitoids across study region, suggesting diversity natural methods suppress at different stages. These included two eight larval parasitoids.

The fall armyworm (Spodoptera frugiperda) (J. E. Smith) is a widespread, polyphagous, and highly destructive agricultural pest. Global climate change may facilitate its spread to new suitable areas, thereby increasing threats host plants. Consequently, predicting the potential distribution for plants under current future scenarios crucial assessing outbreak risks formulating control strategies. This study, based on remote sensing assimilation data plant protection survey data, utilized machine learning methods (RF, CatBoost, XGBoost, LightGBM) construct prediction models 120 Hyperparameter stacking ensemble method (SEL) were introduced optimize models. results showed that SEL demonstrated optimal performance in armyworm, with an AUC of 0.971 ± 0.012 TSS 0.824 0.047.

Understanding predator-prey and predator-predator interactions is essential for evaluating the effectiveness of biocontrol agents developing efficient pest management strategies. This study investigates effects prey species, predator life stage, density on predatory efficiency generalist Rhynocoris fuscipes (Fabricius) under semi-field conditions. Both nymphs adults R. consumed significantly more second-instar larvae S. frugiperda than litura or M. separata. Notably, fifth-instar exhibited higher predation capacity (11.75 ± 0.37 10.90 0.40 larvae) fourth-instar (9.05 0.29 frugiperda. demonstrated a Type II functional response at all developmental stages toward each revealed attack rates (a = 1.5205 0.0544) frugiperda; additionally, handling time did not differ among three species. It suggests that this may be effective controlling noctuid populations low densities. As age increased, intraspecific competition also intensified.

Abstract Coccygidium luteum (Hymenoptera: Braconidae), a solitary larval parasitoid, is associated with the fall armyworm (FAW), in Africa. However, there very limited information on reproductive biology, and other biological parameters that influence its life strategies. We conducted laboratory experiments to gain new insights into biology of C. reared FAW as host. Host age preference, lifetime fecundity, cycle, adult longevity were studied under conditions 28 ± 1°C 70 3% relative humidity. This study revealed prefer early (1st–3rd) instars for oviposition.
