Appetitive 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...
متن کاملFatty Acid Composition of Eggs during Development of the Cotton Leaf-Worm, Spodoptera littoralis Boisduval
Gas-liquid chromatographic analysis of egg lipids during development of Spodoptera littoralis showed the presence of 13 fatty acids ranging in carbon chain length from caproic (C6:0) to linolenic acid (C 18:3). Palmitic, palmitoleic, stearic, oleic and linoleic acids composed over 90% of the total fatty acids. Palmitic acid was always the predominant fatty acid and oleic acid was the second mos...
متن کاملAppetitive and Aversive Learning in Spodoptera littoralis Larvae
Page 725 Adult butterflies are capable of associative learning that serves foraging flowers or finding oviposition sites. In experimental paradigms, they learn to extend their proboscis in response to floral orders associated with a sugar reward or to avoid them if paired with bitter substances. Such settings have been used to elucidate the neuronal circuitry and mechanisms underlying the afore...
متن کاملErratum: Development of insect resistant maize plants expressing a chitinase gene from the cotton leaf worm, Spodoptera littoralis
Due to the importance of chitinolytic enzymes for insect, nematode and fungal growth, they are receiving attention concerning their development as biopesticides or chemical defense proteins in transgenic plants and as microbial biocontrol agents. Targeting chitin associated with the extracellular matrices or cell wall by insect chitinases may be an effective approach for controlling pest insect...
متن کاملInsecticidal and Antifeedant Activities and Chemical Composition of Casimiroa Edulis La Llave & Lex (Rutaceae) Leaf Extract and its Fractions Against Spodoptera Littoralis Larvae
Insecticidal and antifeedant activities of acetone extract of Casimiroa edulis (Rutaceae) leaf were screened against 4 instar larvae of Spodoptera littoralis. Crude extract had LC50 value of 79.47μg/cm and SC50 of 88.97 μg/cm. Seven fractions were then collected from the extract by silica gel column chromatography (eluted by different solvent systems). Four of these fractions recorded percent s...
