The results showed that Pileolaria terebinthi, type species of the genus Pileolaria is not a hemi–form or brachy–form rust species as mentioned among literature by several authors. Study on miscellaneous specimens collected from Iran and locus classicus of the species, France, revealed that P. terebinthi is an automacrocyclic rust and its aecial state is not uredinioi...

The Miocene pyroxene andesite lava flows are exposed in southeastern edge of Urumieh Dokhtar Magmatic assemblage in Iran. The hypocrystalline andesite in parts contain conspicuous co-magmatic igneous enclaves which are dark grey and occur mostly as spherical and occasionally as ribbon shapes with some showing chilled margins. Petrographic study shows that the ribbon type enclaves have been form...

the relationship between female oviposition preference and offspring performance is a key area of study on the evolution of host specificity. this study investigates host prefer-ence of the polyphagous hover fly syrphus ribesii (diptera: syrphidae) and compares it with some components of its offspring`s performance. females and offspring were tested on six naturally used aphid hosts (blackberry...

background: biting habit of mosquitoes plays an important role in the epidemiology of mosquito-borne diseases. mosquitoes use a set of elaborate sensory modalities to find their preferred hosts by exploiting cues emanating from a nearby host. it has been suggested that the chemical profile of skin can provide further support for anthropophilic mosquito species to find their suitable hosts. this...
