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 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 کاملDetoxification System in Spodoptera littoralis against Abamectin
Biochemical and histological analysis were performed on 4 larval instar of the cotton leaf worm Spodoptera littoralis to determine the effect of abamectin (LC50) on the biomarkers acetylcholinesterase (AChE), glutathione S-transferase (GST), α-, βesterase and mixed function oxidase (MFO).Biochemical analysis showed a severe reduction in the enzymatic activities of GST and α-esterase, as compare...
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 کاملComparison of Amino Acid Sequences of Halloween Genes in Spodoptera litura and Spodoptera littoralis
20-Hydroxyecdyone (20E), an active form of ecdysteroid, is the key hormone in insect growth and development. To date five P450 enzymes involved in the last four steps of ecdysteroid biosynthesis from ketodiol to 20E namely Spook (Spo), Phantom (Phm), Disembodied (Dib), Shadow (Sad) and Shade (Shd) related to ecdysteroid biosynthesis, are identified and the character of last four enzymes is well...
