This dissertation dealt with comparing the host-preference in laboratory,searching ability with host plant in cage and greenhouse, crossing relationship amongsome Trichogramma species/strains used to control Ostrinia spp., ovipositon andmating behavior, the dispersal behavior and activity period in daytime, effects ofextracts of corn, mung bean and ECB female scale on searching behavior, functionalresponse, and effect of host eggs stored at low-temperatures on parasitization ofTrichogramma ostriniae.
