Efficiency of Trissolcus spp. (hymenoptera : scelionidae) as egg parasitoids of eurygaster integriceps puton (hemiptera : scutelleridae) in Iran
The natural control exerted by egg parasitoids of Sunn Pest, Eurygaster integriceps Puton, in wheat fields in Varamin, Iran from 1997-1998 was assessed. A total of 306 egg masses were collected and 70 of them (22%) were parasitized by Trissolcus grandis Thomson, T. vassilievi Mayer, T. semisteriatus...

| Zusammenfassung: | The natural control exerted by egg parasitoids of Sunn Pest, Eurygaster integriceps Puton, in wheat fields in Varamin, Iran from 1997-1998 was assessed. A total of 306 egg masses were collected and 70 of them (22%) were parasitized by Trissolcus grandis Thomson, T. vassilievi Mayer, T. semisteriatus Nees or T. basalis Wholaston. Parasitism efficiency was >90% for all species. The impact of these parasitoids on Sunn Pest populations was 22.30% and 23.43% for 1997 and 1998, respectively. |
