Repellent and insecticidal activities of Melia azedarach L. against cotton leafworm, Spodoptera littoralis (Boisd.).
A crude acetone extract and oil of ripe fruits from Melia azedarach L. were evaluated against the 2nd and 4th instar larvae of Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). Both oil and extract exhibited highly significant growth inhibition at all concentrations tested, while the oil of M. azedarach recorded higher insecticidal activity against both instars than the crude extract. GC...
متن کاملEffect of Soybean Trypsin Inhibitor on Digestive Proteases and Growth of Larval Spodoptera Littoralis (boisd.)
Two serine proteases were identified in midgut of 4 instar of Spodoptera littoralis. A trypsin-like one (BApNAhydrolyzing) (TRYP) with a pH optimum at 11.0, and a chymotrypsin esterase-like enzyme (BTEE-hydrolyzing) (CHYMO) with optimum activity at pH 10.0. Serine protease activities were significantly (p < 0.001) inhibited in vitro by soybean trypsin inhibitor (SBI). The incorporation of diffe...
متن کاملInsecticidal and growth inhibiting action of the supercritical extracts of Melia azedarach on Spodoptera frugiperda
This study evaluates the effects of supercritical carbon dioxide extracts obtained from the fruit of Melia azedarach L. (Meliaceae) on the development of Spodoptera frugiperda J.E. Smith, 1797 (Lepidoptera: Noctuidae), from the larval period until the insect adulthood. For this purpose, a laboratory-scale extraction unit was operated at 60 °C and 200 bar. Larval mortality increased by raising t...
متن کاملRepellent and insecticide activity of Pelargonium x hortorum against Spodoptera littoralis (Boisd.).
Insecticide and repellent activity of an acetone extract and oil from fresh leaves of Pelargonium x hortorum (cv. Orangesonne) were evaluated against the 2nd and 4th instar larvae of Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). The oil showed medium toxicity against the 2nd instar and low toxicity against the 4th instar larvae, while the extract showed high significant toxicity at a...
متن کاملAntioxidative Activity of Melia Azedarach Linn Leaf Extract
The antioxidant activity of the melia azedarach was investigated in rats with ethanol-induced erythrocyte damage. Chronic administration of ethanol (20% w/v, 2 g/kg.p.o.,daily for four weeks) increased the level of lipid peroxidation (LPO), decreased the activity of superoxide dismutase (SOD) and catalase and reduced the content of glutathione (GSH). The concurrent treatment of ethanol-admini...
