Dendroctonus jeffreyi and D. ponderosae are sibling species of bark beetles (Coleoptera: Scolytidae) with few morphological and molecular genetic differences. The two species are believed to have diverged relatively recently. Dendroctonus jeffreyi colonizes only Pinus jeffreyi, while D. ponderosae colonizes up to thirteen Pinus spp., but not P. jeffreyi. Adult beetles of both D. jeffreyi and D....

Endophytic fungi promote plant growth through the production of IAA, siderophore and phosphate solubilization. Out of thirty fungal endophytes isolated from tomato roots grown in a stressed, cold climate of Central Himalayan hills of district Pithoragarh, Uttarakhand, India twelve showed distinct morphological and study was undertaken, to understand the plant growth promoting properties possess...

the aim of this study was to isolate and identify airborne fungi from locations in babol city, babolkenar forest and a beach on the caspian sea (all in north part of iran) in spring and summer. of 126 samples collected, the most clinically important isolated fungi were mucor spp. (18.6%) in the forest, alternaria spp. (13.4%) at the beach; and cladophialophora spp. (15.8%), mucor spp. (11.7%) a...

Introduction: Heavy metal contamination has necessitated a less expensive and non-destructive clean-up technique such as mycoremediation. This study aimed to isolate, identify, and evaluate the tolerance of fungi species in different concentrations of heavy metals for their potential use in bioremediation. Materials and Methods: Fungi were isolated by serial dilution and spread plate technique...

School buildings typically serve a number of functions simultaneously, owing to which they seem to be especially exposed to the expansion of fungi with wide enzymatic capabilities, including fungi of the genus Penicillium. In total, 34 isolates belonging to 20 species were obtained within two schools. The most frequently isolated species included: Penicillium chrysogenum, P. waksmanii, and P. c...

Ophiostomatoid fungi were isolated from Scolytus ratzeburgi infesting Betula pendula and B. pubescens in Norway. Fungi were identified based on morphology, DNA sequence comparison for two gene regions and phylogenetic analyses. The most abundant fungus was Ophiostoma karelicum, suggesting a specific relationship between the fungus, the vector insect and the host tree. Our results suggest that O...

garlic and onion are very important crops which are cultivated especially in autumn season in jiroft region, southeast of iran. one of the limiting factors for development of cultivation of these crops is fungal diseases such as leaf spot and blight. for identifying the causal agents of this disease, numerous onion and garlic fields were surveyed during 2001-2003 and infected samples were colle...

Methods Air samples were collected during loading/unloading of stored food grains in a godown with the help of Rotorod sampler, UK on petroleum jelly coated tape at 2900 rpm for 30 minutes, the tapes were then directly inoculated on Sabouraud’s dextrose media for isolation of fungi by imprint smear. Most of the collected samples yield Aspergillus sp., Rhizopus sp., Penicillium sp., Mucor sp. an...
