Summary: This study investigated the genetic architecture and resistance status of fall armyworm (FAW) in China. The findings revealed that the corn-strain of FAW was predominant in China, and some populations exhibited low levels of resistance to certain insecticides. The study also identified gene mutations with relatively high mutation frequencies. The results have significant implications for the development of region-wide chemical control and resistance management strategies for FAW in China.

Summary: The study utilized the CRISPR/Cas9 system to generate an ABCB1 knockout strain of the Spodoptera frugiperda, which showed increased susceptibility to specific chemical insecticides and Bt toxins. This suggests that ABCB1 plays a significant role in the resistance of Spodoptera frugiperda to certain pesticides.

Summary: The study investigates the insecticide resistance status and synergistic effects of gradual doses of three synergists in the fall armyworm population in Hainan. The results show varying levels of resistance in different populations, with some populations showing improved insecticidal efficacy with higher doses. Continued monitoring and appropriate management strategies are recommended.

Summary: Spinosyn insecticides have been widely used to control agricultural pests. In this study, the involvement of Sfrugiperda nAChR alpha 6 (Sf alpha 6) in spinosyn susceptibility was determined using CRISPR-mediated gene knockout. The results showed that disruption of Sf alpha 6 led to high levels of resistance to spinosad and spinetoram. The findings highlight the importance of developing methods to detect and monitor mutant allele frequencies of Sf alpha 6 in global populations of S. frugiperda.

Summary: This study focused on the genetic background and pesticide resistance of the fall armyworm (FAW) in China. The results showed that FAWs invaded into China were most likely originated from Africa and had significant genetic differentiation from American populations. Furthermore, specific detoxification genes in FAWs responded to different pesticides.

Summary: The highly destructive fall armyworm was first detected in China in late 2018, posing a major economic threat to corn production. This article reviews control strategies and discusses the prospects of managing this pest with Bacillus thuringiensis (Bt) corn in China.

Summary: The study investigated resistance levels to chlorantraniliprole and tetrachloropyramid in 13 populations of Spodoptera frugiperda in China. Results showed low resistance levels to diamide insecticides in China, and differences in relative resistance among populations were not caused by mutations in RyR or its expression.

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: This review explores various strategies for controlling Spodoptera frugiperda, including chemical compounds, plant extracts, biological control, and sex pheromone monitoring. Plant extracts and biological control may offer more environmentally sustainable options for combating this pest.

Summary: The study revealed that resistance of Spodoptera frugiperda to emamectin benzoate is polygenic and shows incomplete dominant inheritance. Low cross-resistance was detected between emamectin benzoate and other insecticides. The synergists did not have a significant effect on the Ben-R strain, indicating a minor role of metabolic resistance in resistance evolution.
