Repellent 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 کاملMechanisms of Gustatory Coding in Spodoptera Littoralis
Adult Lepidoptera use their antennae to probe their distant and proximate environment with sensory organs which detect volatile and contact chemicals. In this work, we have investigated the role and the sensitivity of antennal contact chemoreceptors of Spodoptera littoralis. Adults of both sexes have long and filiform antennae composed of about 70 flagellomeres. Each flagellomere bears six tast...
متن کاملSpodoptera littoralis-induced lectin expression in tobacco.
The induced defense response in plants towards herbivores is mainly regulated by jasmonates and leads to the accumulation of so-called jasmonate-induced proteins. Recently, a jasmonate (JA) inducible lectin called Nicotiana tabacum agglutinin or NICTABA was discovered in tobacco (N. tabacum cv Samsun) leaves. Tobacco plants also accumulate the lectin after insect attack by caterpillars. To stud...
متن کاملAppetitive and aversive learning in Spodoptera littoralis larvae.
Adult Lepidoptera are capable of associative learning. This helps them to forage flowers or to find suitable oviposition sites. Larval learning has never been seriously considered because they have limited foraging capabilities and usually depend on adults as concerns their food choices. We tested if Spodoptera littoralis larvae can learn to associate an odor with a tastant using a new classica...
