Antifeedant 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 کاملFour Botanical Extracts are Toxic to the Hispine Beetle, Brontispa longissima, in Laboratory and Semi—field Trials
The potential of botanical extracts such as Celosia argenea L. (Caryophyllales: Amaranthaceae), Ricinus communis L. (Malpighiales: Euphorbiaceae), Mikania micrantha Humboldt, Bonpland & Kunth (Astrales: Asteraceae), and Catharanthus roseus (L.) G. Don (Gentianales: Apocynaceae) for the control of Brontispa longissima Gestro was evaluated in a bioassay and semi-field trial. Dose-response bioassa...
متن کاملAntifeedant Activity of Ginkgo biloba Secondary Metabolites against Hyphantria cunea Larvae: Mechanisms and Applications
Ginkgo biloba is a typical relic plant that rarely suffers from pest hazards. This study analyzed the pattern of G. biloba pest hazards in Beijing; tested the antifeedant activity of G. biloba extracts, including ginkgo flavonoids, ginkgolide, and bilobalide, against Hyphantria cunea larvae; determined the activities of glutathione transferase (GSTs), acetylcholinesterase (AChE), carboxylestera...
متن کاملMoluccensins R-Y, limonoids from the seeds of a mangrove, Xylocarpus moluccensis.
Eight limonoids, named moluccensins R-Y (1, 2, 5-10), and six known compounds, including 6-hydroxymexicanolide (3), were isolated from the seeds of an Indian mangrove, Xylocarpus moluccensis, collected in the estuaries of Andhra Pradesh. The absolute configuration of moluccensin V (7) was confirmed by means of single-crystal X-ray diffraction analysis. The (1)H and (13)C NMR data for 6-hydroxym...
متن کاملIsolation and characterization of eight polymorphic microsatellite loci for the coconut pest, Brontispa longissima (Coleoptera: Hispidae).
Brontispa longissima is one of the most serious insect pests of coconut in Southeast Asia; it was first discovered on Hainan Island in June 2002. Despite the economic risk associated with this pest, genetic aspects of the invasion process have remained relatively unexplored. Using microsatellite markers, we investigated the population structure, genetic variability and pattern of invasion in va...
