The fall armyworm (FAW), Spodoptera frugiperda, causes harm to over 360 plants by eating both the vegetative and reproductive components. While synthetic insecticides have been widely used to manage this pest, they pose a significant ecological risk to beneficial insects. The Trichogramma genus, comprising over 240 parasitoid species, presents a promising alternative to insecticides. They utilize the chemical signals emitted by host eggs to locate and lay their eggs inside, ultimately leading to the host’s death. This review aims to provide comprehensive insights into the potential of Trichogramma species as biocontrol agents of S. frugiperda, highlighting both their potential and challenges in augmentative biocontrol alongside chemical control. penetrative ability, cost of mass-rearing, frequency, and release-timing of the parasitoid, influence its application and effectiveness in managing S. frugiperda in agroecosystems. The typical problem of Trichogramma’s low penetrative ability of scaled S. frugiperda egg mass can be resolved by integrating other parasitoids that can easily penetrate the egg barriers. Also, certain pesticides registered for controlling S. frugiperda require re-evaluation to learn about their effects on Trichogramma species, inform conservation strategies, and promote sustainable pest management.
