The results indicate that female wasps deposit HMPs on the chorion of host eggs with her ovipositor near the end of egg-laying process. Na ye females do not posses the ability for recognizing the marking pheromones and have to obtain the ability though the learning process, in which the wasp inserts her ovipositor into a host egg to determine whether the egg has been parasitized followed by antennal drumming on the exterior. Once the learning process is completed, the female wasp will be able to discriminate between parasitized and unparasitized hosts and reject a parasitized egg by simply drumming on the exterior of the egg. Learning plays an important role in reducing initial rejection time when an unsuitable host is encountered. Female wasps of T. astriniae can quickly learn to associate the presence of a HMP on host egg chrion with the internal status of the egg.

研究结果表明，玉米螟赤眼蜂的寄主标记信息素是在其产卵过程中的收场阶段由产卵器产生的，并且标记在寄主卵表的化学物质；玉米螟赤眼蜂对标记信息素的识别不具有先天性，其必须先用产卵器插入寄生卵来检测是否被寄生，然后其触角不停地敲击，通过学习获得对标记信息素的识别能力，从而放弃了对寄生卵的选择，学习对初始放弃时间有着重要影响，改善了其对寄主搜索效率，这种学习行为是与寄主联系在一起学习的，它能根据寄主被寄生与否而对标记信息素作出反应与不反应。
