abstract in order to evaluate crop water stress index (cwsi) and canopy temperature of wheat cultivars under terminal drought stress, a field experiment was conducted at the agricultural research station of shiraz university, shiraz, during 2009 growing season. five wheat cultivars including shiraz, bahar, pishtaz, sistan and yavaros and four levels of water regime including well watering [irr...

beauveria bassiana (balsamo) vuillemin is an important natural regulator of insect populations. identification of a suitable molecular marker for detecting a virulent phenotype on a target pest would be useful in screening for effective isolates against the pest. nine isolates of b. bassiana were tested for their virulence to adults of tribolium castaneum (herbst) in laboratory bioassay with 1×...

Wireworms are the soil inhabiting larvae of click beetles and can cause severe damage to arable crops such as potatoes (Solanum tuberosum, L.). Several strains of the entomopathogenic fungus Metarhizium brunneum (Petch) are pathogenic to wireworms. In this study, three European strains of M. brunneum were tested in the laboratory against the most damaging wireworm species in Europe, Agriotes li...

Candidate OSPAR/ICES recommended biomarkers at the level of the individual in Mytilus edulis for determination of good environmental status for MSFD were evaluated against contaminant levels at sites around Ireland. The sites chosen ranged from moderate to low pollution levels, but the actual ranking of the sites varied according to the contaminant levels present. At the most contaminated site,...

The red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) is a serious pest of the palm tree in tropical regions of the world. One strain of Metarhizium sp. ZJ-1, isolated from Chinese soils, was evaluated for growth characteristics, and screened for its virulence to R. ferrugineus larvae in laboratory conditions. An approximately 685-bp fragment was amplified by ITS (I...

Objective: In order to investigate effects of different concentration of gibberlic acid and poly amines on germination and early growth of Pishtaz cultivar under salinity stress. Methods: The experiment was carried out as factorial based on completely randomized design with four replicates in laboratory of agronomy and plant breeding of agricultural department, Islamic Azad University, Varamin-...
