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: The fall armyworm arrived in China in late 2018 and has since spread across eastern Asia. Research shows that the flight performance of the fall armyworm is stronger at 20-25 degrees Celsius and 60-90% relative humidity, but flight parameters gradually decrease over five consecutive nights. This study provides baseline information for predicting changes in the geographical distribution, movement patterns, and invasion trajectories of the fall armyworm.

Summary: The fall armyworm (Spodoptera frugiperda) has invaded Africa and quickly spread to most Asian countries since 2016. Studies showed that the invaded populations mainly consist of heterogeneous hybrids (males from the corn strain and females from the rice strain) with a small percentage of homogenous individuals from the corn strain. The genetic diversity of fall armyworm in Africa and Asia was found to be similar, indicating no significant genetic changes due to rapid migration within two years.

Summary: The study confirmed the first immigration of Fall Armyworm (FAW) into China, with the early immigrant population being of the corn strain and mainly colonizing corn in Pu'er, Dehong, and Baoshan areas in Yunnan province. Migration trajectory simulation suggested that the moths might have mainly come from the eastern area in the mid-latitude region of Myanmar.

Summary: With the globalization and agriculture trade development, fall armyworm (FAW) has invaded over 70 countries, posing a serious threat to major crop production. The study used multiple factors to analyze the risk of FAW migration to Europe from 2016 to 2022, and suggested that coastal areas, particularly Spain and Italy, had a high risk of invasion. Early warning based on spatio-temporal data is crucial for multinational pest management and crop protection.

Summary: The fall armyworm is a highly destructive agricultural pest of tropical-subtropical origins, with its population dynamics and crop damage significantly influenced by temperature. This review discusses the biological manifestations and tolerance of the fall armyworm at different temperatures, providing constructive suggestions for control strategies and future research directions. The information presented in the paper aims to enhance understanding of the relationship between insect pests and temperature, strengthen monitoring and pest control efforts, and support the development of effective strategies for global pest management.

Summary: The fall armyworm is one of the most destructive insect pests in the world, and it has invaded Africa and spread to Asia within two years. Glycerol has been found to play a crucial role in the rapid cold hardening process, and the genes GPDH and GK are associated with glycerol synthesis. RNA interference of these genes resulted in a decrease in survival rate in the fall armyworm larvae. After a cold period, an increase in glycerol accumulation was observed. This research highlights the importance of glycerol as a cryoprotectant for the survival of this quarantine pest during the cold period.

Summary: The fall armyworm (FAW) Spodoptera frugiperda is a migratory insect pest that has recently expanded its range to colder regions in East Asia. A study shows that long-term exposure to moderately low temperatures (3 to 15 degrees C) causes indirect chilling injury, which is the most important factor for the survival of S. frugiperda during winter. Adult S. frugiperda are more tolerant to these temperatures than larvae and pupae, but survival decreases significantly at temperatures of 9 degrees C or lower. Short-term daily exposure to higher temperatures helps improve survival, suggesting the existence of a repair mechanism for indirect chilling injury in S. frugiperda.

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: Modeling dispersal of wind-borne pests is a valuable tool in integrated pest management, with both biotic and abiotic factors playing important roles. Uncertainty in key parameters can impact regional infestation forecasts, with spatial variability depending on local landscape specificity, particularly in areas with less frequent infestations.
