Antifeedant activities of secondary metabolites from Ajuga nipponensis against adult of striped flea beetles, Phyllotreta striolata

Abstract: Antifeedant activities of the isolated chemical compounds from Ajuga nipponensis, were studied against adult of striped leaf beetles. The methanol, petroleum ether, ethyl acetate and n-butanol extracts at 1.0 mg/ml, were used in this study. All four extracts exhibited more than 65 antifeedant index at 24 h and ethyl acetate extract showed significant activity against striped leaf beetles with 83.12 antifeedant index. Six compounds and one fraction were isolated by chromatography and their structures were ident… Show more

“…Both apigenin and genistein are known for their anti-herbivore properties. Apigenin is highly toxic to larvae of southern house mosquito Culex quinquefasciatus Say (Diptera: Culicidae), affects the fecundity, mortality, and food consumption of Formosan termite Coptotermes formosanus Shiraki (Blattodea: Isoptera: Rhinotermitidae), shows antifeedant activity against striped flea beetles Phyllotreta striolata (Coleoptera: Chrysomelidae) 59 61 . Apigenin reduced the pea aphid abundance and phloem sap ingestion on alfalfa, caused a reduction in the number and duration of probes when added to saponin mixtures in artificial diets, and was accumulated in vegetative parts of aphid-infested pea plants 62 .…”

“…Different methods such as using synthetic pesticides are prefered for pest management, but fast acting synthetic pesticides causes several ecological problems [33]. Recently, biological pesticides have been originated from plants and plant-derived products [34] such as extracts take attention, because they are safer, more friendly and more efficient alternatives to synthetic pesticides [35].…”
