Abstract
Backround: Helicoverpa armigera is major maize pest, while Conopomorpha cramerella is cocoa is main insect pest. Their larvaes lie in corn cob and cocoa pulp which can be controlled using egg parasitoids. Methods: Exploring H. armigera eggs on female flowers on a corn plant along the 50 m line at 10 points with a 4 m distance to obtain parasitoids. C. cramrella. Egg parasitoids were obtained by taking eggs from cacao pod, while Corcyra cephalonica from egg traps along a straight line with 10 points with 3 m distance. Result: H. armigera egg parasitoids include Trichogramma sp. and Trichogrammatoidea armigera. Corn grown in between coconut palms has higher parasitism than without coconut palm shade and highest parasitism was in Bolaang (60.91±2.52 %). Parasitoids of Trichogaramma sp. produce unrearable female offsprings in C. cephalonica eggs. Dominant Trichogrammatoidea sp. were found in egg traps while only two C. cramerella parasitized eggs were found in cacao pod. Dominant Trichogaramma sp. Parasitoids in egg traps were found in Tombariri. C. cephalonica egg trap is the latest method for monitoring Trichogrammatoidea sp parasitoid The parasitism of Trichogrammatoidea sp. on C. cramerella eggs and C. cephalonica egg traps is low.
