Augusman Waruwu, 2022. The Egg Parasitoid is exploration of Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) in Purwobinangun Village, Sei Bingai District, Langkat Regency, guided by Maryani Cyccu Tobing  and Ameilia Zuliyanti Siregar. Species of parasitoids on maize is the beginning to control S. frugiperda pests. An Integrated Pest Management (IPM) strategy is needed to reduce the population of S. frugiperda. This research was carried out on land owned by farmers in Purwobinangun Village, Sei Bingai District, Langkat Regency (February to June 2021).

The results showed that 2 genera egg parasitoids of S. frugiperda are Telenomus and Trichogramma. The highest parasitization  (28,32%) was in the intercropping treatment of maize variety Pioneer 32 (P1V0) and the lowest parasitization (12,47%) was in the monoculture treatment of maize variety Bisi 18 (P0V1). The egg parasitoid of  S. frugiperda was dominated by the Telenomus.
