(BOISD.)

T
he cotton leaf worm,
Spodopetra littoralis
(Boisd.) is a highly polyphagous insect that causes serious dam-
ages 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 sec-
tions 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.
