The ethanolic extract of two plants Mentha arvensis (Lamiaceae) and Nerium
oleander (Apocynaceae) were tested for direct toxicity action on last phase larvae
of Ectomeylois ceratoniae (Lepidoptera: Pyralidae),one of the most serious pests on
pomegranates and other trees. Three sets of Concentration 2.5%, 5% and 7.5%
were tested. Percent mortality was recorded at intervals of time for each plant
extract. Data analysis was made by using Complete Randomized Design (CRD).
The results showed that mortality effect varies according to extract type,
concentration and time period .The time 12 h showed higher insecticidal effect with
the tested plants, Strong toxicity effect was observed at concentration 7.5 %. The
LT50 values were 1.10, 1.05 and 0.30 for Mentha arvensis and 1.75, 1.48 and 0.90
for Nerium oleander.
