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 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 ...
متن کاملSpatial 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...
