Summary: The threat of invasive species is on the rise due to global trade and habitat disruption. This study uses the Triosephosphate isomerase gene (Tpi) as a marker for host choice phenotype and phylogenetic analysis, revealing genetic differentiation between populations and supporting the existence of host strains. Regional variations in host strain behavior are identified through the efficacy of different molecular markers.

Summary: The study found that corn is the preferred oviposition host for both rice and corn strains, and corn strain is more tolerant to Cry1F corn tissue compared to the rice strain. Hybrid populations have similar performance to corn strain in terms of Bt toxin tolerance.

Summary: The main benzoxazinoid found in corn, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA), elicits different larval responses from different pest moths. Fall-armyworm (FAW) corn and rice strains showed differential performance and gene expression when reared on DIMBOA-enriched artificial diet, indicating an intrinsic cost for FAW rice strain larvae to metabolize corn-originated hydroxamic acids.UDP-glucuronosyltransferase plays a central role in an effective response to DIMBOA in FAW larvae.

Summary: Spodoptera frugiperda is a highly polyphagous and invasive agricultural pest that can harm over 300 plants and cause significant economic losses. In this study, the gut microbial community of S. frugiperda was found to be influenced by different host plants and treatments, playing a crucial role in host adaptation. Understanding the symbiotic relationships between invasive organisms and microorganisms is essential for developing more effective pest management strategies.

Summary: The fall armyworm is a polyphagous insect pest, preferring maize but also able to complete its life cycle on sorghum and wheat. Rice is a non-preferred host plant for fall armyworm. Larval diets significantly impact development time, fecundity, and survival rates of the insect. Maize is found to be the most suitable diet for fall armyworm based on the study's findings.

Summary: This study found that olfaction plays a crucial role in the host selection process of the fall armyworm. The moths showed a strong preference for maize, sorghum, and wheat for oviposition, while cowpea was the least preferred. The identification of terpenes as potential attractants provides valuable insights for the management of this pest.

Summary: The fall armyworm, Spodoptera frugiperda, is a polyphagous global pest that preferentially feeds on gramineous crops such as corn, sorghum, and pasture grasses. It consists of two genetically distinct host strains known as the corn and rice strains, complicating pest management approaches. Through molecular markers and TaqMan assays, researchers are able to differentiate between strains and interstrain hybrids, allowing for future studies on strain population dynamics and hybrids. Understanding the ecology of S. frugiperda strains is crucial for informing effective management strategies.

Summary: This study found that the fall armyworm can survive and reproduce on bananas, although they prefer maize as their host. The larvae that fed on bananas had a longer developmental duration and slower population growth compared to those that fed on maize. The survival probability and reproductive capacity of the fall armyworm were lower when fed on bananas compared to maize.

Summary: Sustainable control of fall armyworm (FAW) requires implementation of effective integrated pest management strategies, with host plant resistance as a key component. Significant opportunities exist for developing and deploying elite maize cultivars with native genetic resistance and/or transgenic resistance for FAW control in both Africa and Asia.

Summary: This review provides a list of practical pest management options for fall armyworm in maize, including host plant resistance, agronomical, cultural, biological, botanical, chemical, and biotechnology approaches. The study found that cultivating tolerant genotypes, adjusting sowing windows, and implementing specific intercultural and cropping system measures, along with chemical and non-chemical pest management strategies, showed promising results for the sustainable management of fall armyworm.

Summary: This study examined the impact of two grasses (napier and natal grass) and one legume (sunn hemp) crop on the population growth of the fall armyworm, a lepidopteran pest. The findings showed that the alternative host plants significantly influenced the development and reproduction of the pest. Sunn hemp was identified as a more suitable host plant, while natal grass was less suitable. The results imply that all alternative host plants can support the growth and development of the pest in the absence of the main host.

Summary: Field strains of fall armyworm have developed resistance to Bt protein Cry1F in Brazil, Argentina, and the United States. This study found that mutations conferring resistance to Cry1F in three strains of fall armyworm are present in a single locus, providing valuable information for developing effective strategies for Bt resistance management.

Summary: The fall armyworm is a major agricultural pest in China. This study evaluated the behavior and performance of the fall armyworm on different host plants and found that maize was the most optimal for its growth and development, while barley and faba beans were the least optimal. This research enhances our understanding of the fall armyworm and can aid in pest management strategies.
