Antifeedant and phytotoxic activity of hydroxyperezone and related molecules.
The insect antifeedant and toxic activity of hydroxyperezone (1), its derivatives 2-9, along with 3-hydroxy- (10) and 6-hydroxythymoquinone (11) were studied against Spodoptera littoralis, Leptinotarsa decemlineata, and Myzus persicae. The antifeedant tests showed that L. decemlineata was the most sensitive insect, followed by M. persicae, while S. littoralis was not deterred by compounds 1-11....
متن کاملShort communication. The antifeedant activity of natural plant products towards the larvae of Spodoptera littoralis
Worms are becoming difficult pests to control since many insecticides are now forbidden and the present alternatives are insufficiently effective. Antifeedants of plant origin may have potential against such pests. In this work, several diterpenoids, flavones and coumarins extracted from plants were assayed as antifeedant agents against Spodoptera littoralis larvae. Among these compounds, four ...
متن کاملAntifeedant activity of some polygodial derivatives.
Polygodial (1) and its derivatives acetal 2 (propylene) and 3 (ethylene) were prepared and their antifeedant activity and toxic effects evaluated on several insect species with different feeding ecologies (Spodoptera littoralis, Leptinotarsa decemlineata, Myzus persicae and Rhopalosiphum padi) along with that of polygonone (4). We also tested their selective cytotoxic effects on insect-derived ...
متن کامل3-O-Acetyl-narcissidine, a bioactive alkaloid from Hippeastrum puniceum Lam. (Amaryllidaceae).
In the context of the study on plant defensive compounds we have isolated the main alkaloid from Hippeastrum puniceum (Amaryllidaceae), 3-O-acetyl-narcissidine (1), and its biological activities tested against two divergent insect species and several plant species. 1 was isolated from the bioactive alkaloidal fraction of H. puniceum. Its chemical structure was established by spectroscopic analy...
متن کاملSelective action of acetogenin mitochondrial complex I inhibitors.
Five annonaceous acetogenins, rolliniastatin-1 [structure: see text], rolliniastatin-2 [structure: see text], laherradurin [structure: see text], squamocin [structure: see text], annonacin [structure: see text], and rotenone as a reference, differing in their NADH oxidase inhibition activity, have been evaluated for antifeedant, insecticidal, trypanocidal and cytotoxic effects on insect, mammal...
