The repellant and antifeedant properties of Cyperus articulatus against Tribolium casteneum Hbst.

Antifeedant, Growth Regulatory and Ovicidal Effect of Sambucus ebulus L. Extract on Tribolium confusum Duv.

Aqueous extract from leaves of Sambcus ebulus L. were tested for antifeedant, growth regulation and ovicidal effects against the red floor beetle Tribolium confusum Duv. under laboratory condition (29?1?C, RH 60?5% and 12L:12D). The results indicated a significant deterrence for feeding, and comparatively significant larval, pupal and adult weight decrease in treated vs. controlled insects. Sim...

Antifeedant Activities of Lignans from Stem Bark of Zanthoxylum armatum DC. against Tribolium castaneum.

The speciation of a methanolic extract of Zanthoxylum armatum stem bark has enabled the isolation and characterization of 11 known lignans. Among them, five compounds (6, 8-11) are reported in this plant for the first time. All of the chemical structures were elucidated on the basis of NMR spectral analysis. Additionally, their antifeedant activities against Tribolium castaneum were evaluated s...

Phytoremediation Potentiality of Cyperus Articulatus L

The phytoremediation potentiality of Cyperus articulatus naturally growing in industrial wastewater was tested. Nine heavy metals were selected for this purpose; As, Cd, Cr, Cu, Fe, Hg, Mn, Ni and Pb. Metal concentrations were measured using the atomic absorption. The accumulation rates of the studied heavy metals showed considerable variations in the accumulation abilities according to the pla...

Antifeedant diterpenoids against Tribolium castaneum from the stems and twigs of Ceriops tagal (Rhizophoraceae).

The screening of several Chinese mangrove plants for insecticidal principles showed that ethanol extract of Ceriops tagal stems and twigs possessed significant feeding deterrent activity against the red flour beetle, Tribolium castaneum (Family: Rhizophoraceae). From the ethanol extract, three feeding deterrent diterpenoids were isolated by bioassay-guided fractionation. The compounds were iden...
