Abstract:
The cotton leaf worm, Spodopetra littoralis (Boisd.) is a highly polyphagous insect that causes serious damages to more than 112 plant species belonging to 44 different families in Africa. The toxic effect of Ipomea carnea extracts against fourth instar larvae of Spodoptera littoralis was evaluated under laboratory conditions. Based on LC50 and LC90 values, Ipomea carnea extracts were recorded (24.622 and 164.947 ppm respectively) for the most potent one (acetonic extract) followed by hexane (232.677 and 15377.590 ppm respectively) and finally the alcoholic extract which doesn’t reveal any toxicity until five days post treatment. Ultra structure sections were made for the epithelial cell of midgut and muscles for 4th instars larvae treated with LC25 and LC50 of acetonic extract of I. carnea which caused vacuolization in the cytoplasm, degeneration of organelles and destruction of the plasma membrane according to the ultrastructure studies on S. littoralis larvae.
