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 Different Host-plants on Development and Fecundity of the Cotton Leafworm, Spodoptera Littoralis (boisd.) (lepidoptera: Noctuidae)
Studies on the effect of different host-plants on the development and fecundity of the cotton leafworm S. littoralis were carried out under constant laboratory
متن کاملAn Agar-Free Insect Rearing Artifical Diet: A New Approach for the Low Cost Mass Rearing of The Egyptian Cotton Leafworm, Spodoptera littoralis (Boisd.)(Lepidoptera: Noctuidae)
A new formula for insect rearing artificial diets without using any of their conventional gelling agents was provided in the present work, for the first time. Larvae of the Egyptian cotton leafworm, Spodoptera littoralis (Lepidoptera: Noctuidae) were successfully mass-reared, for nine consecutive generations on an agar-free artificial diet. This suggested medium is based on yellow lentils, Lens...
متن کاملIn Vivo Pyro-SIP Assessing Active Gut Microbiota of the Cotton Leafworm, Spodoptera littoralis
The gut microbiota is of crucial importance for the host with considerable metabolic activity. Although great efforts have been made toward characterizing microbial diversity, measuring components' metabolic activity surprisingly hasn't kept pace. Here we combined pyrosequencing of amplified 16S rRNA genes with in vivo stable isotope probing (Pyro-SIP) to unmask metabolically active bacteria in...
متن کاملCharacterization of Multisugar-Binding C-Type Lectin (SpliLec) from a Bacterial-Challenged Cotton Leafworm, Spodoptera littoralis
BACKGROUND Various proteins that display carbohydrate-binding activity in a Ca(2+)-dependent manner are classified into the C-type lectin family. They have one or two C-type carbohydrate-recognition domains (CRDs) composed of 110-130 amino acid residues in common. C-type lectins mediate cell adhesion, non-self recognition, and immuno-protection processes in immune responses and thus play signif...
