The paper discusses the identification of potential bio-control agents against sugarcane stem borers in Negros Island, Philippines. Four species of Trichogrammatoidea are described, highlighting their mass-rearing capabilities and efficiency as biological control agents. The study emphasizes the importance of Trichogramma chilotraea and Trichogrammatoidea nana in parasitizing specific pest eggs, Tetramoera schistaceana and Chilotraea infuscatellus, with significant parasitism percentages observed in the field.
