the functional response of aphidius ervi to different sitobion avenae densities on two wheat cultivars (sardary and alvand) was examined in laboratory conditions. experiments were carried out in test tubes on an f2 lab generation without wheat clusters and also on f2 and f5 generations in pots using wheat clusters. in the tubes, female wasps were exposed to aphid densities of 2, 4, 7, 14, 28, 3...

background: the alcoholic decoction of root ethanolic extract of aristolochia ringens is taken orally to treat various ailments in south-west nigeria without prior knowledge of its potential toxic effect. therefore, this study aimed at assessing the toxicity potentials of root ethanolic extract of a. ringens on functional indices and histology of the liver. methods: twenty male rats were random...

the stage specific functional response of the acarophagous ladybird beetle stethorus gilvifrons mulsant to varying densities of citrus brown mite eutetranychus orientalis (klein) eggs was examined in a simplified castor bean leaf arena under laboratory conditions. all stages of s. gilvifrons were individually isolated for 24 hours with different prey densities at 30âºc and a photoperiod of 14: ...

in this study, chemical composition and functional properties of red bean, chickpea, lentil and canellini bean were evaluated. our results revealed that chickpea had the highest protein (43.4%) and fat (5.17%) content and lentil, red bean and canellini bean were the following ones. the isoelectric point of all the samples were determined as about ph=4 but other than lentil, the remaining sample...

the seeds of lepidium sativum (garden cress) were selected as a new source of hydrocolloid and some of its fundamental physico-chemical properties such as intrinsic viscosity and functional group were determined. ftir analysis showed that this polymer was composed of carbohydrate with functional carboxyl and hydroxyl groups. intrinsic viscosity was determined to be 1.33 ml/mg in water. the hydr...
