گونه های euphorbia maculata و e. consanguinea که به ترتیب از شمال و شمال شرق ایران جمع آوری شده اند برای اولین بار از منطقه فلورا ایرانیکا و ایران گزارش می شوند
To study the chemical constituents of Euphorbia antiquorum L., the constituents were isolated with normal-phase and reverse-phase silica gel column chromatography and their structures were elucidated on the basis of spectroscopic data. Seven terpenoids were obtained from EtOAc extract of E. antiquoru L. They were identified as antiquorine A (1), antiquorine B (2), ent-13S-hydroxy-16-atisene-3,1...
Fractions obtained from partitioning of aerial methanolic extract of Euphorbia Aelleniiwith chloroform (E2), ethyl acetate (E3), n-butanol (E4) and water (E5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. Sample E2 appeared to have significant phytotoxic activity. In the insecticidal screening study onl...
Phylogenetic relationships within the tribe Moriomorphini Sloane, 1890 are analyzed cladistically based on 75 morphological characters and 21 ingroup terminal taxa rooted at a Trechus obtusus Erichson outgroup. Based on the resultant cladistic relationships, two subtribes-Moriomorphina and Amblytelina Blackburn, 1892-are recognized, with the following new synonymies proposed: Meonides Sloane, 1...
We evaluated the effects of snow cover and debris cover on overwintering success of Aphthona from 2001 to 2004 in southeast North Dakota. Chill degree-days, soil temperature, and duration of soil temperatures were monitored in field plots. Emergence of Aphthona from soil cores collected in October and held in the laboratory under simulated winter conditions did not differ across treatments. Fie...
Three trials were conducted to determine if low ingestion of some leafy spurge (Euphorbia esula L.) by sheep is primarily due to differences in sheep or in leafy spurge. In the first trial, pastures in Idaho and North Dakota were grazed by sheep originating from both states. Generally, sheep from both states grazed the leafy spurge growing in the Idaho pastures reluctantly but grazed the leafy ...
