ABSTRACT Five species of Trogoderma Berthold are reported from Iraq. These are: I inclus,n LeCont. T. granarium Everts, T. variable Ballion. I. bactrianum Zantiev and T. irroraturn Reitter. A key to the species is presented, with redeseriptions and illustrations of all species. INTRODUCTION Trogoclernia Berthold is one of the largest genus in the family Dermestidae. It includes more than 120 species (Morcskowski. 1968). some of them are economically important. Several work have been done on the species of this genus in different part of the world such as Hinten (1945). Beal (1954) and Zantiev (1976). In Iraq no work has been done on this group except that some species appeared in faunistic lists such as Hussain (1963). who reported I granarium Everts. and I versicolor creuts. ( I inclusum LeCont.). El-Haidari et al. (1972( recorded T inclusurn and Thompson (1977) reported I. variable Ballion. Mawlood (1985) classified three specie I inclusum, T granariuni and I irroratun. and Abdul-Rassoul (1996) added T. bactrianun Zantiev for the Iraqi lists. This work presents redescription and distinguishing five species of Tregoderma so far have been found in Iraq. MATERIALS AND METHODS The specimens were collected during March to August 1989 from different localities in Baghdad. Diyala. Erbil and Mosul. The specimens were placed in boiling water for ten minutes to soften their parts. Then the parts were.seperated by two fine pins, to remove parts and put in 10% KOH which placed in water bath for five to fifteen minutes. After that placed in distilled water for few more minutes in order to neutralise the alkali. The parts are placed in ethyl alcohol 75% and dissected under microscope, then these parts were placed in Canada balsam to support slides for subsequent examination under microscope.
