Potent limonoid insect antifeedant from Melia azedarach.
Systematic fractionation of a fruit extract from Argentine Melia azedarach L., which was monitored by an insect antifeedant bioassay, led to the isolation of meliartenin, a limonoid antifeedant, which existed as a mixture of two interchangeable isomers. At 4 microg/cm2 and 1 microg/cm2, the isomeric mixture was as active as azadirachtin in strongly inhibiting the larval feeding of Epilachna pae...
متن کاملAntifeedant/insecticidal terpenes from asteraceae and labiatae species native to Argentinean semi-arid lands.
To validate the potential as added-value resources of Asteraceae and Labiatae species of Argentinean semi-arid lands, we have selected 13 of their major terpenoids belonging to several chemical classes and tested their insect antifeedant and toxic activity on the herbivorous insects Spodoptera littoralis and Leptinotarsa decemlineata. The antifeedant effects of the test compounds were structure...
متن کاملLabelling studies on the biosynthesis of terpenes in Fusarium fujikuroi.
Synthetic [2-(13)C]mevalonolactone was fed to the gibberellin producer Fusarium fujikuroi and its incorporation into four known terpenoids was investigated by (13)C NMR analysis of crude culture extracts. The experiments gave detailed insights into the mechanisms of terpene biosynthesis by this fungus.
متن کاملFeeding and Molt Inhibition by Azadirachtins A, B, and 7-Acetyl-azadirachtin A in Rhodnius prolixus Nymphs
The antifeedant and antimolting effects of azadirachtins A and B, and of a synthetic derivative, 7-acetyl-azadirachtin A were examined. Given through a blood meal, the effective dose (ED50) for the antifeedant effect ranged from 25 to 30 ng/ml of blood for the three compounds. ATP, a phagostimulant, also given orally, reversed the antifeedant action of azadirachtin A. The ED50 values for molt i...
متن کاملAntifeedant activity of plant extracts to an insect Helopeltis theivora.
The different solvent extracts (viz Petroleum ether Ethyl acetate and Methanol) obtained from leaves and flowers of Heliotropium indicum and Spilanthes calva were screened for antifeedant activity against Helopeltis theivora. All the six different extracts showed antifeedant activity at four different concentrations. The methanolic extracts of leaves of Heliotropium indicum and Spilanthes calva...
