fauna of ichneumonidae of isfahan province was studied in 2012. specimens were collected using sweep net and malaise trap on various plants from different places in isfahan. totally, 18 species belong to 16 genera and 7 subfamilies were collected and identified as: anomalon cruentatum (geoffroy, 1785) (anomaloninae); exetastes syriacus schmiedeknecht, 1910 (banchinae); diplazon laetatorius (fab...

Pollen grains of Malvoideae (Malvaceae) which corbiculate bees cannot collect constitute a floral filter that excludes pollen-collecting bumble and honey from exploiting pollen resources. Although large, spiny are in fact harder to compact for collection by bees, morphology (e.g., grain diameter, spine length) is not itself reliable indicator collectability. In this study, we discovered two spe...

In this paper, the short injection method using GC-EI (+) MS/MS with end-point back-flush and dynamic-multi-reaction mechanism technique was validated for simultaneous determination of pesticide residues in dry Hibiscus syriacus L. applying QuEChERS extraction covering 176 GC-amenable residues. The GC optimum temperature program achieved a run time it 20 minutes. linearity evaluated matrix matc...
