title: A survey of gregarines associated with Tenebrio molitor and Opatriodes vicinus in the central region of Saudi Arabia.
abstract: The present work recorded five species of septate gregarines in the intestine of two species of insects they were: Gregarina polymorpha (Hamm.), in the gut of Tenebrio molitor (L.), percentage of infection 100%, with a density of 2-6 and G. cuneata (Stein), in the gut of T. molitor (L.), percentage of infection 100% with a density of 15-17; Hirmocystis harpali (Watson), in the mid gut of Opatriodes vicinus (Fairmaire), percentage of infection 34%, with a density of 19-28 and Leidyana sp., in the mid gut of O. vicinus percentage of infection 17%, with a density of 2-11 and Spharorynchus chabaudi percentage of infection 33% with a density of 100-180 in an infected insect. Members of genus Gregarina are considered to be coccidian and malarial organisms, however, till now gregarines cause little or no damage to their hosts.
