Large and diverse genera, such as Silene need more reliable morphological traits for the credible identification and delimitation of the species. Despite the fact that the type of indumentum among the species of Silene had been addressed in most available revisions, monographs and floristic studies, the trichome-based features and their adaptational importance have not been investigated explici...

three genera and species from the family ichneumonidae, viz. diadegma majale gravenhorst, campoletis thomsoni roman and hyposoter notatus gravenhorst are newly recorded from iran. these species were collected from shiraz and vicinity and the identification confirmed by jussila, finland, university of turku. the members of the subfamily campopleginae to which these three species belong are known...

the fauna of the superfamily bombylioidea was studied in alborz province, iran during 2012. two families (bombyliidae and mythicomyiidae), eight genera and ten species were identified, of which two species, exoprospora dispar loew, 1869; parageron lutescens (bezzi, 1925), are new records for the iranian fauna. an identification key for the species of the family mythicomyiidae known from iran is...

aphids are among important agricultural pests. the pest's evolutionary tendency towards a loss of taxonomically useful characteristics, as well as morphological plasticity due to host type and as a result of environmental factors, make a morphological identification of aphids difficult, whereas exact identification is indispensable for managment of these pests. thus, modern identification ...

Pythium species are cosmopolitan, fungus-like oomycotes which may cause diseases in plants, animals and even human beings. Some of the species, however, are saprophytes and also well-proven biological control agents of plant pathogenic fungi. Since 1968, when the first Pythium species was reported from Iran, ca 44 species, two varieties, and five groups of this genus have been reported from dif...

introduction many studies have shown epidemiological links between strains isolated in tap water, and those isolated from patients. molecular methods linked to pcr are more reliable and faster for identification of             non- tuberculous mycobacteria(ntm). in this study molecular methods were used for identification and typing of ntm. materials and methods five hundred ml of 85 water samp...

background: sarcocystosis is one of the most widespread parasitic diseases in cattle caused by three main species of sarcocystis genus. the major aim of this study was to determine the prevalence of sarcocystis spp. in meat produced in yazd, central iran with special reference to species identification, using polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp).  method...
