Research progress on chemical synthesis and application of the sex pheromone of Spodoptera frugiperda

Sex pheromone is one of the most promising and environment-friendly strategies to control the fall armyworm moth. In this review, the separation process, structure identification and application of the sex pheromone of Spodoptera frugiperda were summarized. Its compoments comprise monoolefinic esters and diolefinic esters. The chemical synthesis of the sex pherpmone were reviewed. Among them, the construction of the Z- double bond was mainly involved in catalytic hydrogenation of alkyne, Z-selective cross metathesis of olefin, Z-olefin, Wittig coupling, vinylic organoborane and ring opening of cyclooctadiene and the E-one included Grignard coupling, ring opening of cyclepropylethanol and E-olefinic ester. Besides, the current problems and the future researches of the sex pheromone of S. frugiperda were discussed.
