(Heteroptera: Scutelleridae) in overwintering areas. Adults of this pest become inactive during hibernation and aestivation about nine months in overwintering areas. These areas are very important for biological control of this pest. Because the overwintering adults with entomoparasitic nematodes can be easily collected from there and they can be sent to uninfected overwintering areas for inoculation. The success of this method depends on the morphological diagnosis of individuals infected with mermithids. It is necessary recognizing the individuals that infected with nematodes collected from overwintering areas to be used as biological control agent for the pest management. As a result of the studies carried out for this purpose, it was determined that the bodies of parasitized SP individuals have a wet and greasy appearance. The movement of infected SP is slowed when near nematodes leaving from the host body. Insect head extends forward, the neck is prolonged and nematodes are usually left the body from the cervix. Before leaving from the hosts, the mean distance between the head at eye level and the thorax was measured as 419.4 ± 117.30 μm (n = 11).Keywords : Eurygaster, Hexamermis, Mermithidae, entomoparasitic nematode
