Morphological diagnosis of Sunn pest, Eurygaster integriceps (Heteroptera: Scutelleridae) parasitized by Hexamermis eurygasteri (Nematoda: Mermithidae)
Öz
Hexamermis eurygasteri Tarla, Poinar and Tarla (Nematoda: Mermithidae) is an important natural
enemy of Sunn pest (SP), Eurygaster
integriceps Put. (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).
