Spodoptera frugiperda (Lepidoptera: Noctuidae), commonly known as fall armyworm, was first detected in Uganda 2016 and has spread to all the maize-growing districts. Different methods have been deployed control this pest. However, there is a limited understanding of role environment farmers’ practices on abundance damage by S. Uganda. This study, therefore, assessed leaf levels three different districts explored association between agronomic practices, crop phenology, weather parameters smallholder maize fields using longitudinal monitoring survey 69 Kole, Kiryandongo, Nakaseke for seasons. The numbers egg masses adults were generally low. highest trapped followed Nakaseke, lowest Kole. Leaf incidence damaged plants differed significantly larvae varied at growth stages. Conservation tillage, reduced weeding frequency, increased rainfall high maximum temperatures associated with damage. No significant relationship observed pesticide or cropping systems influence fertilizer use contradictory across seasons Timely vigilant scouting, proper timing measures, minimum tillage should be included an IPM strategy frugiperda.

Abstract The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is a globally significant agricultural pest, causing severe damage to corn production in China. Chemical odor‐based trapping major approach for FAW control, making it essential understand the antennal sensillum types enhance development of effective chemical odor attractants. In this study, we comprehensively examined sensilla FAW, identifying eight and two subtypes, including Böhm's bristles, trichoidea, chaetica (I II), coeloconica, styloconica, squamiformia auricillica, basiconica. Sensilla II, II are reported first time study. Detailed low‐voltage field emission scanning electron microscope (LVSEM) images descriptions provided each type. This study provides morphological information aid conducting neurophysiological tests on FAW. Research Highlights were examined,

The fall armyworm (Spodoptera frugiperda) poses a substantial threat to many important crops worldwide, emphasizing the need develop and implement advanced technologies for effective pest control. CRISPR/Cas9, derived from bacterial adaptive immune system, is prominent tool used genome editing in living organisms. Due its high specificity adaptability, CRISPR/Cas9 system has been various functional gene studies through knockout applied research engineer phenotypes that may cause economical losses. practical application of diverse insect orders also provided opportunities developing strategies genetic control, such as drive precision-guided sterile technique (pgSIT). In this review, comprehensive overview recent progress S. frugiperda presented. We outline fundamental principles applying embryonic microinjection highlight study genes associated with biological aspects, including body color, insecticide resistance, olfactory behavior, sex determination, development, RNAi. ability technology induce sterility, disrupt developmental stages, influence mating behaviors illustrates roles management strategies. Furthermore, review addresses limitations studying function explores future potential promising controlling pest.
