Abstract:

Orius albidipennis Reuter populations are widely common in many regions of Iran what makes them appropriate for biological control of small arthropods, especially thrips, in fields and greenhouses. In this research, adults of O. albidipennis were collected from 12 various locations in Iran during 2006-2009. Populations were collected from Tehran, Gorgan, Mashhad, Zabol, Kerman, Yazd, Esfahan, Shiraz, Bandar Abbas, Rudan, Shahr-e-kord and Hamadan. Nucleotide sequences of the internal transcribed spacer 1 and the flanking regions of the nuclear ribosomal gene were compared between O. albidipennis populations. The objective of this research was to evaluate genetic variations among and within O. albidipennis populations in different regions of Iran. Samples were placed in 96% alcohol for DNA extraction. DNA was extracted from individual insects using a Bio-Rad^TM Kit. Genetic variation within and among Orius albidipennis populations was evaluated with XLSTAT 2009 and Arlequin 3.1 softwares. Results showed that the majority of genetic variation is among populations and not within populations, indicating O. albidipennis in Iran may not be an interbreeding population. Mantel test revealed that there was a significant correlation between the geographic distance and genetic dissimilarity. Phylogenetic analysis showed that Bandar Abbas and Rudan populations were genetically most dissimilar among populations. We suggest that the genetic variability between O. albidipennis is high and internal transcribed spacer 1 (ITS 1) is an appropriate gene for determination of genetic variation among and within O. albidipennis populations.
