Antimicrobial activity and phytochemical screening of Maerua pseudopetalosa (Glig and Bened.) DeWolf

Chloroform, ethyl acetate and ethanol, which were used for the extraction of Maerua. pseudopetalosa parts, gave nine extracts with different colors, consistencies and extractabilities. Four bacterial strains (Bacillus cereus, Escherichia coli, Staphylococcus aureus and Salmonella typhi, and three fungal species: Aspergillus fumigatus, Aspergillus flavus and Candida albicans) were tested for antimicrobial activities of the extracts. […]

Potentially beneficial rhizobacteria associated with banana plants in Juja, Kenya

Climate and its changes have a direct impact on the development of the different hydrobiont species. These effects on aquatic organisms could be either positive or negative. Every species adapts specifically to natural periodic and seasonal changes, however, the response to unexpected climate changes is inconsistent and not always adequate. Climate-related factors could influence food […]

Bio-efficacy of Azadirachta indica A. Juss oil extracted from sun- and shade-dried seeds against two stored-product beetles

Azadirachta indica is a source of highly effective botanical insecticides, with Azadirachtin A as the major active principle. However, it has been contended that sun-drying reduces its Azadirachtin A content and insecticidal efficacy. This work investigated the Azadirachtin A content, fatty acid contents, adult toxicity, F1 progeny inhibition and damage reduction of A. indica oils […]

Anatomical study of Astragalus sect. Caprini (Leguminosae) from NE Iran

This study has examined petiole and leaflet anatomy characteristics of 20 species of the Astragalus sect. Caprini from Khorassan Razavi Province (NE Iran) using light microscopy. For this, cross section of the fresh or dried mature petiole and leaflet were prepared and stained by differential staining. Some differences were notice in the outline shape of […]

The role of phenological stages of Hammada salicornica on grazing management and sustainable utilization of rangeland forage

Hammada salicornica is a key range species in arid regions. In this study, phenological stages of Hammada salicornica were investigated at two desert vegetative regions of AbBarik Bam (Kerman province) and Tabas (Yazd province) during 2008-20111. In each vegetative region, after the registration of geographical features, 10 species of Hammada salicornica were selected and then […]

Comparative foraging behavior of eastern honeybee, (Apis cerana F) and western honeybee, (Apis mellifera carnica) in pollinating pear and apricot flowers in Taleghan, Iran

The Eastern honeybee, (Apis cerana), is indigenous to Asia and is an important pollinator for Asian ecosystems; the Western honeybee, (Apis mellifera), has been introduced to Asia because of its high honey yields. European honeybee, (Apis mellifera carnica) is native to the Iranian continent and is adopting apiaries by the beekeepers in Iran. The results […]

Analytical characterization of fatty acids present in seed oils by gas chromatography-Mass spectrometry and qualitative determination of various phytonutrients in dandelion plant

The current research was carried out to determine the phytochemicals constituents in the species of dandelion. Quantitative screenings of fatty acids was also carried out in our lab. Derivatives of methyl ester of fatty acids were analyzed. The analysis was carried out using gas chromatography coupled to mass spectrometer. The result of 19 different fatty […]

Bio geographical distribution of Trissolcus semistriatus Nees (Polygasteroidea: Scelionidae) an egg parasitoid of sunn pest, Eurygaster integriceps puton (Hemiptera: Scutelleridae) in Iran

Trissolcus semistriatus is an egg parasitoid showing the crucial role in plant protection as biological control agents on Eurygaster integriceps under different climatic conditions. The geographical distribution of T. semistriatus was studied using Maximum Entropy (MaxEnt) in different climatic regions of Iran. Records of 1161 specimens collected from 24 climates, altitude and climate variable data […]
