- During 2009–2010, a field survey of native Trichogramma species was carried out in six provinces of Iran, including Khorasan Razavi, Tehran, Mazandaran, Guilan, Golestan, and Qom. In this study, a molecular method for identifying Trichogramma and for determining the prevalence of Wolbachia in those species was used. Based on ITS2 (internal transcribed spacer 2) sequence, 14 populations were identified as the species T. embryophagum, T. evanescens, or T. brassicae. Wolbachia infection in these Trichogrammatids was detected using wsp gene sequencing. The highest infection rates in Trichogramma were found in Mazandaran and Golestan provinces. There was no evidence of infection in Trichogramma species in Guilan and Qom provinces. Of the three infected populations, two populations of T. evanescens were infected with only one Wolbachia strain from sib subgroup and one population was superinfected. Here, we report the first data on molecular characterization of Iranian Trichogrammatids and their Wolbachia-endosymbionts.
