Soybean grown at latitudes of ~20° or lower can produce lower grain yields due to the short days. This limitation can be overcome by using the long juvenile trait (LJ) which delays flowering under short dayconditions. Two LJ loci have been mapped to the same location on Gm04, J and E6. The objective of this research was to investigate the e6 allele in 'Paranagoiana' and determine if E6 and J are the same locus or linked loci. KASP markers showed that e6 lines did not have the j-1 allele of LJ PI 159925. A population fixed for E1 but segregating for E6, with e6 introgressed from Paranagoiana, showed single gene control for flowering and maturity under short days. Sequencing Glyma.04G050200, the Jgene, with long amplification Taq found that the e6 line 'Paranagoiana' contains a Ty1-copia retrotransposon of ~10,000bp, inserted within exon 4. PCR amplification of the cDNA of Gencing Glyma.04G050200, the J gene, with long amplification Taq found that the e6 line 'Paranagoiana' contains a Ty1-copia retrotransposon of ~10,000 bp, inserted within exon 4. PCR amplification of the cDNA of Glyma.04G050200 also showed differences between the mRNA sequences (presence of insertion in j-x). Hence, we conclude that the loci E6 and J are one locus and deem this new variation found in Paranagoiana as j-x.Pyrethroid and indoxacarb are commonly used pesticides to control the fall armyworm (Spodoptera frugiperda) in the crops. There are a series of consequences caused by the use of pyrethroid and indoxacarb pesticides under emergency control, such as pest resistance development, contamination of soil, water, and farm products. This study analyzed the structure and physiological function of the sodium channel in S. frugiperda, which is an important step to elaborate the resistance mech
