Antifeedant Activity of Plant Extracts Against Spodoptera litura (Fab.) (Lepidoptera: Noctuidae)
Botanicals act not only as insecticides but also function as antifeedants, oviposition deterrents and ovicides. The present investigation reports on the antifeedant property of leaf components of Curculigo orchioides, Evolvulus alsinoides, Phyllanthus deblis, Swertia corymbosa and Zanthoxylum limonella. Solvent residues of these leaf components obtained from different solvent extracts dissolved...

متن کاملBioactivity of Carica papaya (Caricaceae) against Spodoptera frugiperda (Lepidoptera: Noctuidae).
The composition of a chloroform seed extract of C. papaya was determined by GC-MS. Nineteen compounds were identified, with oleic (45.97%), palmitic (24.1%) and stearic (8.52%) acids being the main components. The insecticidal and insectistatic activities of the extract and the three main constituents were tested. Larval duration increased by 3.4 d and 2.5 d when the extract was used at 16,000 ...
متن کاملPotential of Entomopathogenic Fungi for Biocontrol of Spodoptera Litura Fabricius (lepidoptera: Noctuidae)
Susceptibility of different biological stages of Spodoptera litura to various strains of entomopathogenic fungi was evaluated under laboratory conditions at Department of Entomology University of Agriculture, Faisalabad using the insect immersion method. Virulence potential of the entomopathogenic fungi varied with different biological stages of the insect pest. Eggs and larvae were comparative...
