Spatial representation of odours in the antennal lobe of the moth Spodoptera littoralis (Lepidoptera: Noctuidae).
Glomeruli within the antennal lobe (AL) of moths are convergence sites for a large number of olfactory receptor neurons (ORNs). The ORNs target single glomeruli. In the male-specific cluster of glomeruli, the macroglomerular complex (MGC), the input is chemotypic in that each glomerulus of the MGC receives information about a specific component of the conspecific female sex pheromone. Little is...
متن کاملFlight attraction of Spodoptera littoralis (Lepidoptera, Noctuidae) to cotton headspace and synthetic volatile blends
The insect olfactory system discriminates odor signals of different biological relevance, which drive innate behavior. Identification of stimuli that trigger upwind flight attraction toward host plants is a current challenge, and is essential in developing new, sustainable plant protection methods, and for furthering our understanding of plant-insect interactions. Using behavioral, analytical a...
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 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 کاملCROP PROTECTION Growth Disruption, Abnormalities and Mortality of Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) Caused by Azadirachtin
Azadirachtin is the most effective compound of the neem tree, Azadirachta indica A. Juss, with insecticidal and growth disruption properties on several species of insects. Its effects on the development and survival of Spodoptora littoralis (Boisduval) were studied under laboratory conditions. Third-instar larvae were individually fed on artificial diet treated with azadirachtin (from 0.01 ppm ...
