The effect of intra- and interspecific conditioning of host eggs was examined with regard to the discriminative ability of the two mono-parasitic parasites of Nezara viridula L., viz. Asolcus mitsukurii ASHMBAD and Telenomus nakagawai WATANABE. These two species scrape and mark the egg surface with the tip of their ovipositor after oviposition. A female of either species can distinguish the eggs which have been marked by another female of the same species and she will restrain from oviposition. She can not, however, distinguish the eggs previously marked by the females of another species. This resulted in a multiple parasitism followed by larval competition in the host egg, giving rise to A. mitsukurii as the usual victor. Both physical attack and physiological suppression of T. nakagawai by A. mitsukurii were thought as the possible underlying processes to determine the result of larval competition.
