Abstract

Population fluctuation of sunn pests’ parasitoids was studied in 3 different regions Garmsar (Semnan province), Islam-Shahr (Tehran province) and Savojbelagh (Alborz province). Totally nine parasitoid species including, Trissolcus basalis (Wollaston, 1858), T. djadetshkoi Rjachovsky, 1959, T. grandis Thomson, 1861, T. rufiventris Mayr, 1908, T. semistriatus Nees, 1834, T. simoni Mayr, 1879, T. vassilievi Mayr, 1903, T. festivae (Viktorov, 1964) (Scelionidae) and Ooencyrtus telenomicida (Vassiliev, 1904) (Encyrtidae) were collected and identified. Upon the samplings in Garmsar 3 species T. semistriatus, T. grandis and T. rufiventris were collected which the Percent parasitism of the two dominant species T. semistriatus and T. grandis were obtained 28. 32% and 39. 78%, respectively in 5th May. In Islam-Shahr 5 species T. grandis, T. vassilievi, T. basalis, T. simoni and O. telenomicida were collected which of these, T. grandis was determined as the dominant species with 49. 72% parasitism in 8th April. In Savojbelagh 4 species T. vassilievi, T. rufiventris, T. djadetshkoi and T. festivae were collected which 2 of them T. vassilievi and T. chloropus with 24. 56% and 18. 37% parasitism respectively, were the dominant species. About the Sex ratio of the mentioned parasitoids, the mean percent producing of females was higher than males in all the sampled regions.
