Abstract

The host preferences of Trissolcus semistriatus Nees, an egg parasitoid of Sunnpest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae) were studied under laboratory conditions (25±1 ºC & 65±5% RH) in accordance with “free-choice” experimental design. For this purpose eggs of E. integriceps, Dolycoris baccarum (L.), Holcostethus vernalis (Wollf) and, Eurydema ornata (L.) and Piezedorus lituratus (Fabr.) (Hemiptera: Pentatomidae) were exposed to T. semistriatus adults for 8 days. T. semistriatus parasitized eggs of E. integriceps and above mentioned Pentatomidae species with the averages of 45.1±7.3%, 29.0±2.6%, 15.6±2.8%, 5.7±6.3% and 4.6±1.9%, respectively. According to the results, it was concluded that E. integriceps was the most preferred species, followed by D. baccarum. It was also emphasized that taking environmental precautions to maintain natural populations of these species, H. vernalis, E. ornata and P. lituratus would be in favor of sustaining bio-control of Sunn pest.

Özet

Deneme laboratuar şartlarında (25 ± 1 ºC ve % 65 ± 5 orantılı nem) “çoklu tercih” düzeninde kurulmuş, bu amaçla Süne, Eurygaster integriceps Puton (Hemiptera: Scutelleridae) yumurta parazitoiti, Trissolcus semistriatus Nees (Hymenoptera, Scelionidae)’un E. integriceps, Dolycoris baccarum (L.), Holcostethus vernalis (Wollf), Eurydema ornata (L.) ve Piezedorus lituratus (F.) (Hemiptera: Pentatomidae) türlerinin yumurtalarını parazitlemede 8 gün süresince tercihleri (%) belirlenmiştir. T. semistriatus, E. integriceps ve öteki Pentatomidae türlerini sırasıyla ortalama % 45.1 ± 7.3, % 29.0 ± 2.6, % 15.6 ± 2.8, % 5.7 ± 6.3 ve % 4.6 ± 1.9 oranlarında parazitlemiştir. Bu sonuçlara gore T. semistriatus’un E. integriceps’ten sonra en çok tercih ettiği Pentatomid türünün D. baccarum olduğu anlaşılmış; Süne ile biyolojik savaşta bu tür başta olmak üzere H. vernalis, E. ornata ve P. lituratus’un da doğada varlığını sürdürmesine yönelik çevre önlemlerinin alınmasının yararlı olacağı vurgulanmıştır
