PCR molecular identification of the fall armyworm in the Chontalpa region, Tabasco, Mexico

O Objective: To perform the first molecular characterization of barcoding COI region S. frugiperda found in Tabasco and to test whether it can reliably identify strain detected said state. Design/Methodology/Approach: We collected specimens using four pheromone traps placed corn plots. Subsequently, we implemented DNA extraction, PCR with LCO-L/HCO-L primers, sequencing six individuals captured traps. Results: After aligning sequences, developed a phylogenetic tree, determining that belongs rice (RS). Implications: Identifying is necessary for management purposes, since different strains may require control methods. Findings/Conclusions: Our study revealed isolates from Chontalpa, Tabasco, Mexico, match RS fall armyworm reported other latitudes. Consequently, this report Tabasco. findings are relevant because species potentially become pest sugarcane- rice-growing areas
