Trichogramma species that could parasitize Corcyra eggs with different adhesives were determined. This study was laid out in 2 x 4for split plot design. The different Trichogramma species, namely: T. chilonis Ishii, T. japonicum Ashmead, and T. evanescens Westwood composed the main plot and the different adhesives, namely: A1 Gum arabic), A2 Elmer's sup TM parasitization of Corcyra eggs did not differ significantly among Tricogramma species, although numerically, the highest number of parasitized eggs was by T. evanescens. Regardless of parasitoid species, the adhesives also showed no significant effect on the percentage of parasitized eggs. Nonetheless, the highest number of parasitized eggs was in Elmer's sup TM glue and the interaction between parasitoid species and adhesives yielded a significant result in the percentage of parasitized eggs. The data on the percentage of remaining eggs after physical disturbance showed highly significant difference among species and adhesive. The most number of eggs that remained on the strip was T. evanescens and adhesive. The most number of eggs that remained on the strip was T. evanescens. Regardless of species, the adhesives showed highly significant influence on the number of eggs that remained after physical disturbance. The most number of eggs that remained glued was in Elmer's sup TM glue. The interaction between species and adhesives revealed a significant result in the number of eggs that remained glued after physical disturbance.
